[00:00:02] <zeeshan> o
[00:00:13] <_methods> yeah little mini mill
[00:00:31] <zeeshan> i honestly wanted to do plasma after my mill
[00:00:31] <jdh> the canononical mini-mill for cheap cnc conversions
[00:00:34] <zeeshan> but fak, im out of space
[00:00:39] <zeeshan> i'd need to design it to fold up
[00:00:41] <zeeshan> and store in the backyard
[00:00:42] <zeeshan> haha
[00:00:45] <zeeshan> and work outdoors
[00:01:21] <_methods> yeah i don't need any big machines since i have them at work
[00:01:32] <_methods> if i need to do any real machining i can just do it there
[00:01:55] <zeeshan> honestly i have access to some nice cnc's at the research lab
[00:02:00] <zeeshan> but its such a pain in the ass to get time on them
[00:02:09] <zeeshan> and have to listen to other people's way to do something
[00:02:12] <zeeshan> sometimes you just wanna get stuff done
[00:02:42] <_methods> well they are their machines so you are at their mercy
[00:02:50] <_methods> i can't just go break a setup down lol
[00:02:53] <_methods> i'd get my ass beat
[00:03:03] <zeeshan> yea
[00:03:08] <zeeshan> and if its for production purposes
[00:03:12] <zeeshan> i'd prolly get banned
[00:04:53] <_methods> to say the least
[00:05:27] <zeeshan> plus i'd like to make sex toys on my machines
[00:05:30] -!- Nick001-shop has quit [Remote host closed the connection]
[00:05:38] <zeeshan> which wouldnt be appropriate at the research lab
[00:05:39] <zeeshan> :-)
[00:05:54] <zeeshan> 'meluvulongtime bot v1.0'
[00:05:59] <_methods> i guess that depends on what your lab researches
[00:06:04] <zeeshan> haha thats true

[00:36:00] <jdh> looks like the new draftsight pro version has some sort of CAM built in
[00:36:59] <_methods> wut
[00:37:01] <_methods> no shot
[00:37:12] <_methods> the free version?
[00:37:18] <_methods> oh nm
[00:37:21] <_methods> pro
[00:37:40] <zeeshan> i wonder if 4 vfds running ast the same time
[00:37:50] <zeeshan> with no filters will blow up my utility transformer
[00:37:52] <zeeshan> down the street :)
[00:37:55] <zeeshan> *ast = at
[00:38:29] <_methods> hell i still use and old version of cimco to drip and do quick programs
[00:39:05] <ssi> zeeshan: at least it's not yours to replace ;)
[00:39:16] <zeeshan> haha
[00:39:23] <zeeshan> if i blow it enough times
[00:39:26] <zeeshan> i wonder if they'll give me 3 phase
[00:39:35] <ssi> doubt it!
[00:39:39] <zeeshan> did you know
[00:39:45] <ssi> if you blow it enough times they might make you pay for it tho!
[00:39:47] <zeeshan> 3 phase people have to pay $250 / mo for delivery
[00:39:52] <zeeshan> on top of any electrical charges
[00:40:01] <_methods> it's regional
[00:40:13] <zeeshan> that is a bit of rape
[00:40:19] <zeeshan> considering i only pay l ike 120 a month in electricity
[00:40:26] <zeeshan> even going balls out with the welder
[00:40:32] <ssi> _methods: I bumped my quote up to 85c due to the time
[00:40:37] <ssi> _methods: and I just got the goahead on it
[00:40:43] <ssi> so I'm about to burn up the first 24x36 sheet :)
[00:41:01] <_methods> \congrats man
[00:41:11] <ssi> the other guy, on top of being more money, told him 10 business days
[00:41:19] <ssi> I'm gonna try to have the first 25% of the parts done this weekend
[00:41:26] <ssi> 10 days on 25% of the parts no less

[00:41:48] <zeeshan> ssi
[00:41:50] <zeeshan> how much moneys
[00:41:53] <zeeshan> $$$$$44
[00:42:03] <zeeshan> a billion dollars
[00:42:10] <ssi> about $3600 for this first run

[00:42:26] <zeeshan> sweet
[00:42:32] <zeeshan> pretty much paid for your laser cutter in 1 job
[00:42:32] <zeeshan> haha
[00:42:42] <ssi> they want four runs as fast as I can do them
[00:42:53] <ssi> actually closer to five
[00:42:54] <zeeshan> sex toys?
[00:42:56] <ssi> 6160 sets altogether
[00:43:33] <SpeedEvil> :)
[00:43:40] <ssi> honestly the plastic parts are making me wish I had a little injection molding machine :P
[00:43:40] <zeeshan> what are you making
[00:43:55] <zeeshan> why dont you get a 3d printer
[00:43:59] <zeeshan> it'd only take you 10 years to make those
[00:44:01] <zeeshan> :)
[00:44:02] <ssi> I have a 3d printer :P
[00:44:02] -!- anarchos2 has quit [Read error: Connection reset by peer]
[00:44:05] <zeeshan> it was a joke
[00:44:06] <zeeshan> haha
[00:44:08] <ssi> yeah that's not happening
[00:44:15] <ssi> I have some experience with trying to mass produce parts on a 3d printer
[00:44:17] <ssi> it's not pretty
[00:44:28] <SpeedEvil> In principle, ganged heads

[00:44:45] <ssi> https://pbs.twimg.com/media/B0rD5-RIIAAiNMD.jpg:large
[00:44:50] <ssi> that's what I'm making
[00:45:02] <zeeshan> thats some thick material
[00:45:02] <ssi> that's basically a "set", except half of them will have no center hole
[00:45:09] <ssi> it's just 1/4"
[00:45:10] <zeeshan> wait the orange stuff
[00:45:12] <zeeshan> or black
[00:45:17] <ssi> both
[00:45:18] <zeeshan> ok
[00:46:27] <SpeedEvil> Seems ideal to punch

[00:47:05] <zeeshan> acrylic go boom
[00:48:58] <ssi> yeah actually punched out of .090" aluminum would be great I think
[00:49:03] <ssi> except my punch isn't up yet
[00:49:09] <ssi> and they designed them in plastic for whatever reason :)
[00:49:24] <zeeshan> i think you'd shatter the acrylic
[00:49:26] <zeeshan> if you tried to punch it
[00:49:55] <zeeshan> i think you have the ideal process :P
[00:50:15] -!- _DannyK_ [_DannyK_!~nicktoolo@] has joined #linuxcnc
[00:50:47] <SpeedEvil> i WAS ASSUMING IT WAS RUBBER
[00:51:16] <_DannyK_> Any one here use Solidworks SimulationXpress?
[00:51:22] <ssi> first batch on at 8:51
[00:51:31] <ssi> SpeedEvil: the orange is silicone
[00:51:36] <ssi> the black stuff is 1/4" cast acrylic
[00:51:40] <SpeedEvil> ah
[00:51:48] <zeeshan> dannyk what are you trying to do
[00:51:53] <ssi> these go on the end of some custom extrusion they did, and they're endcaps
[00:51:57] <SpeedEvil> :)
[00:52:10] <ssi> they're light fixtures, and it's 700VDC across the lights, and there's water spraying everywhecre
[00:52:14] <ssi> very hostile environment :)
[00:53:00] <_DannyK_> Simple pressure analysis. I was wondering where the hell is the value I selected of 5000psi
[00:53:09] <_DannyK_> only in the report?
[00:53:12] <zeeshan> static analysis?
[00:53:23] <_DannyK_> "Resultant Displacement"
[00:53:33] <_DannyK_> yeah
[00:53:36] <_DannyK_> static
[00:53:42] <zeeshan> youll see green arrow where you applied pressure
[00:55:13] <_DannyK_> I see no green arrow.
[00:55:32] <_DannyK_> I see a overall yield strength witha red arrow
[00:57:26] <zeeshan> take a screeenshot and post it
[00:57:31] <zeeshan> i dunno what youre trying to do :P
[00:57:38] <zeeshan> youre trying to find the location of max stress?
[00:59:53] <_DannyK_> Actually I was trying to figure out how much a extruded piece with a flat bottom hole in it would flex at the opposing face on the extruded part.
[01:01:38] <zeeshan> so youre trying to find max displacement
[01:02:31] <_DannyK_> Wait, is the animation amplified?
[01:02:37] <zeeshan> yea
[01:02:40] <zeeshan> look at the displacement numbers
[01:02:59] <_DannyK_> oh, those SW jerks..
[01:03:40] <_DannyK_> I asked because I looked at the Max numbers..
[01:03:48] <_DannyK_> Thanks good to know
[01:04:10] <zeeshan> i hope you know those values
[01:04:13] <zeeshan> are an approximation :P
[01:04:26] <zeeshan> and you need to refine your mesh to ensure they dont change

[01:06:45] <zeeshan> once youre satisfied with your simulation
[01:06:45] <_DannyK_> More beer will solve this faster..
[01:06:47] <zeeshan> refine the mesh
[01:06:51] <zeeshan> resolve it
[01:06:57] <zeeshan> if the numbers change significantly, you know its mesh sensitive
[01:07:13] <_DannyK_> Alrighty good to know
[01:07:36] <_DannyK_> Thank you zeeshan

[01:25:43] <_DannyK_> :P
[01:25:44] <ssi> after dinner perhaps :)
[01:25:53] <PetefromTn_> Burn baby BURN!!
[01:25:59] <ssi> PetefromTn_: that's what I'm hoping to avoid :)
[01:26:07] <ssi> I don't feel comfortable leaving it running unattended just yet heh
[01:26:11] <zeeshan> why
[01:26:19] <zeeshan> let it be!
[01:26:22] <PetefromTn_> what no midnight machining?
[01:26:23] <ssi> fire risk
[01:26:38] <ssi> midnight machining is fine
[01:26:42] <ssi> just no machining while I'm not home
[01:27:09] <ssi> although I do get alerts on my phone from my smoke alarm
[01:27:10] <ssi> :P
[01:27:58] <zeeshan> lol
[01:28:04] <zeeshan> i have so many of these contactors

[01:29:18] <ssi> Rab: yeah I've seen heads melt badly before, but nothing quite that bad
[01:29:55] <zeeshan> knock on wood
[01:29:57] <zeeshan> no fires here
[01:30:08] <zeeshan> unless it was brake cleaner trying to kill those big mosquitos
[01:30:33] <zeeshan> it is very effective
[01:30:37] <ssi> I might run by walmart while I'm out and get a couple spare extinguishers actually :P
[01:30:45] <zeeshan> dude
[01:30:48] <zeeshan> ive been meaning to do that for the shop
[01:30:52] <ssi> yeah it's a good idea
[01:30:53] <zeeshan> the one in my rx7 is dischargedf
[01:30:56] <zeeshan> i fucking hate how they discharge
[01:30:57] <ssi> I've been meaning to have one by the laser
[01:30:59] <zeeshan> after a year of sitting
[01:30:59] <ssi> but now is the time
[01:31:07] <ssi> since I have to run it for a freakin month straight
[01:31:23] <ssi> I would like to put some kind of temp probe in the coolant water too so I can keep an eye on it

[01:34:23] <t12> http://www.sensata.com/klixon/thermostat-precision.htm
[01:34:45] <ssi> yeah maybe
[01:34:47] <jdh> hey pete
[01:34:50] <ssi> I wouldn't put it on the laser power tho
[01:34:52] <ssi> estop worst case
[01:34:56] <t12> or yeah
[01:34:56] <zeeshan> run it to linuxcnc!
[01:34:58] <ssi> best case, feedhold + laser enable
[01:34:59] <t12> something obvious
[01:35:00] <zeeshan> monitor temp! :D
[01:35:08] <ssi> zeeshan: that's what I want to do

[01:35:14] <zeeshan> rtd type sensor
[01:35:16] <zeeshan> or thermocouple
[01:35:21] <PetefromTn_> yeah
[01:35:35] <jdh> guess where I'll be tomorrow.
[01:35:46] <PetefromTn_> gee I wonder...
[01:36:33] <zeeshan> i forgot what chip i was using
[01:36:44] <zeeshan> it was an ADC of some sort

[01:40:15] <ssi> good ol' JT
[01:40:21] <ssi> always making handy stuff for us to use :)
[01:41:17] <PetefromTn_> Kinda surprised it is not built in really.
[01:42:01] <ssi> I think these are running in under an hour
[01:42:02] <ssi> which is awesome
[01:42:07] <ssi> 1/4 sheet per hour
[01:42:22] <PetefromTn_> how many sheets?
[01:42:31] <ssi> four sheets in the first batch
[01:42:38] <ssi> plus all that again in silicone, but the silicone cuts at 100ipm
[01:42:46] <ssi> approx five batches overall
[01:43:01] <ssi> so 20 24x36" sheets of acrylic
[01:43:18] <ssi> rendered into teeny little 1.6x0.7" rectangles :)
[01:44:09] <zeeshan> ssiu
[01:44:12] <zeeshan> can you stack the sheets
[01:44:16] <zeeshan> and cut through multiple?
[01:44:17] <ssi> no, I tried that
[01:44:33] <ssi> was a nice idea though :)

[03:40:44] <cathode> the shaft is 1-1/4" diameter
[03:41:18] <cathode> it needs to be able to handle quite a lot of torsional force. i'm building a bandsaw from scratch

[03:53:52] <cathode> thanks
[03:54:33] <ve7it> a bushing bolts into the hub taper and locks onto a shaft (lightest duty version seems to be good for 1000 in-lbs
[03:55:25] <cathode> i guess i could surface mount the wheel onto the flange of that
[03:55:42] <ve7it> They are easy to take on and off... the bolts are removed and used as jacking screws to push the taper apart.... I used these to make hubs for a go cart many years ago
[03:55:45] <cathode> i actually bought a browning Q-D type bushing to install the cast iron pulley onto the other end of the shaft
[03:55:50] <cathode> yeah
[03:56:04] <cathode> they're nice. but the wheel i'm trying to affix is of my own making
[03:56:19] <cathode> it's a wooden 20" diameter wheel for the bandsaw blade to ride on
[03:56:52] <cathode> i don't have tools that allow me to drill a precisely perpendicular bore through the middle... it ends up with wobble no matter how accurate i can get
[03:57:03] <ve7it> I welded the hub on page 132 to a piece of 1/2"plate and then trued the whole thing up on a lathe
[03:57:14] <cathode> i have neither a welder nor a lathe
[03:57:16] <cathode> nor access to them
[03:57:25] <cathode> i have a woodworking shop not a machine shop
[03:57:43] <XXCoder> cathode: shims?
[03:57:44] <cathode> hence my predicament..
[03:58:08] <ve7it> you could buy one of the sprockets say 8" in diameter with a tape lock hub and then bolt your wheel to it

[03:59:37] <cathode> hmmm
[04:00:10] <ve7it> how about using something like a boat trailer axle/bearings... they allready come with flanges for bolting on the whelles
[04:00:28] <ve7it> sorry (sp)!
[04:00:31] <cathode> those would be considered idlers though yeah?
[04:00:46] <cathode> i have to transmit torque through the shaft
[04:01:10] <cathode> i would just buy a pair of cast iron wheels but the cheapest i can find are $500 for a pair
[04:01:22] <ve7it> yes, you would still need a drive pulley/sprocket
[04:01:27] -!- Sigmac has quit [Quit: Leaving]
[04:01:30] <cathode> that's more than i've spent on the entire project. and i'm already over-budget
[04:02:24] <XXCoder> there is ways to make crappy lathe
[04:02:31] <XXCoder> but good enough for your needs
[04:02:40] <roycroft> is your problem centering the hole or boring the hole perpendicular to the wheel hub?
[04:02:45] <XXCoder> one of em is drill press
[04:02:49] <cathode> roycroft - both
[04:02:58] <roycroft> is the wheel hub flat?
[04:03:04] <cathode> but the perpendicularity is the hardest
[04:03:05] <cathode> yes
[04:03:05] <XXCoder> you need to figure how to build other end so it holds stock
[04:03:14] <roycroft> what size does the hole need to be?
[04:03:19] <cathode> 1-1/4"
[04:03:41] <cathode> i have a forstner bit that does a good job, gives me a snug fit on the shaft
[04:03:42] <roycroft> if you have a power drill and a spade bit you can drill a pretty accurate hole
[04:03:57] <roycroft> go get a pipe flange at a local hardware store
[04:04:08] <roycroft> 1" might be ok, but you might need 1-1/4"
[04:04:24] <cathode> mmmmk?
[04:04:24] <roycroft> it will be a flat flange with a threaded pipe fitting
[04:04:41] <roycroft> get a short 1" or 1-1/4" nipple to screw into the flange
[04:04:43] <ve7it> http://www.princessauto.com/pal/en/Axles/1000-lb-4-Bolt-Posi-Lube-Stub-Axle/8217242.p is hard to beat, but you would need to attache a pulley to the big wood wheel
[04:05:11] <roycroft> then go to the brass bushing department and get bushing (or a couple nested ones) that fit the shaft of the spade bit snugly and fit the id of the pipe snugly
[04:05:20] <roycroft> and you'll have a decent guide for the drill
[04:05:26] <roycroft> center the hole as best you can
[04:05:42] <cathode> i already did something similar with my forstner bit
[04:05:47] <cathode> it still wobbles a bit
[04:05:59] <cathode> keep in mind that even half a degree off, it won't work
[04:06:11] <roycroft> yeah, the guide needs to be pretty accurate
[04:06:18] <tjtr33> "it's a wooden 20" diameter wheel for the bandsaw blade to ride on" could you modify a 20" bike wheel? accurate, axle is square to rim...
[04:06:19] <roycroft> the fit of the bushings has to be very tight
[04:06:48] <cathode> this is my design... the end result is pretty close: https://dl.dropboxusercontent.com/u/88948814/Shop/Bandsaw/2014-06-21_0127.png
[04:07:10] <CaptHindsight> heh, they have align the parts off camera http://www.youtube.com/watch?v=Ic3jfVwmDyQ#t=22 they should call it pick and nearly place :)
[04:07:22] <cathode> tjtr33 - the rim of a bike wheel is concave, not convex. i'm not sure how i would modify that
[04:08:02] <roycroft> i'm assuming you need two of those wheels
[04:08:06] <roycroft> are they identical?
[04:08:06] <cathode> yep
[04:08:08] <cathode> yes
[04:08:16] <cathode> the wheels are already constructed
[04:08:20] <roycroft> so cut the wheel slightly oversize
[04:08:28] <ve7it> I have seen homemade bandsaws built with car tires/rims/bearings where the blade runs on the rubber tire
[04:08:30] <roycroft> when the bores are done, mount each wheel in turn on the driven shaft
[04:08:51] <cathode> ve7it - that's a bandsaw mill. i know what you mean
[04:08:53] <roycroft> and rig up some kind of rest so you can turn the wheel to final diameter in place
[04:09:20] <cathode> a bandsaw mill is for cutting logs into planks. i'm making a shop bandsaw for cutting curves and resawing
[04:09:27] <XXCoder> cathode: are you trying to size inside hole or what>
[04:09:28] <cathode> roycroft - already done
[04:09:59] <cathode> i don't really know how to explain better than i have already... the wheels are not coming out perpendicular to the shaft
[04:10:15] <roycroft> yeah, i get that
[04:10:30] <cathode> my drill press only has an 8" swing, so it can't reach the middle of the wheels (as they're 20" diameter)
[04:10:53] <roycroft> perhaps you can find some bearings that are flange-mounted
[04:11:01] <roycroft> cut the center hole oversize
[04:11:09] <roycroft> slightly
[04:11:16] <cathode> i guess i could resort to shimming like XXCoder mentioned earlier
[04:11:41] <roycroft> and use a flange-mounted bearing block on either side
[04:11:55] <roycroft> you can align them with a shaft and then attach them permanently
[04:14:01] <tjtr33> dunno how wide your blades are, but the center of tire rims is sometimes flat http://goo.gl/bjkYe6
[04:14:34] <roycroft> my wood bandsaw blades do best on a slightly convex tire
[04:15:26] <roycroft> and i think that, with the wooden wheels already made, cathode probably wants to make them work, and not use something else
[04:15:35] <ssi> yeah convex wheels tend to want to track in the center if they're coplanar
[04:15:45] <XXCoder> roy yeah woodgears bandsaw wheels is convex slightly. it keeps blade centered on wheels
[04:15:51] <roycroft> and it's easy to make them coplanar
[04:18:57] <cathode> yep
[04:19:12] <roycroft> that link reminds me that i have to fire up solidworks and do some work on my router design tonight
[04:19:22] <cathode> once i get the bandsaw running i'll take a sanding block and add like 2-4 degree convex bevel to the wheels
[04:19:26] <cathode> ok guys
[04:19:33] <ssi> I need to get my damn commutation converter working
[04:19:42] <ssi> I think I've decided to shelve the rev2 converter if possible
[04:19:45] <roycroft> i would look for flang-mounted bearing blocks, cathode

[04:20:32] <cathode> i failed to mention that i had drilled a hole through the end of the shaft
[04:20:38] <tjtr33> quite a few vids on making bandsaw wheels
[04:20:54] <cathode> so i used a block of wood with a hole drilled through it and a long hex bolt to secure the wood
[04:21:05] <cathode> and clamped the wheel to that (eventually will bolt or glue it on)
[04:21:13] <cathode> it seems to be a lot better
[04:21:26] <cathode> i took a curved file and filed the bore of the wheel itself so that it had some play

[04:23:06] <cathode> fortunately the drill press i have is dead on accurate
[04:23:12] <cathode> <3 craigslist
[04:25:02] <roycroft> i bet you could mount a long 3/4" router bit and a collar on your router and make a guide template to route out the bore
[04:25:07] <XXCoder> ssi: can script it to play sound at m30?
[04:25:10] <roycroft> that would be pretty accurate
[04:25:26] <ssi> I don't have any sound hooked up to the machine
[04:25:28] <ssi> but yeah perhaps
[04:25:35] <cathode> roycroft - maybe. i think i can make this work (the video i just showed)
[04:25:39] <ssi> actually what'd be awesome is script it to send me a push notification to my phone or something :P
[04:25:53] <XXCoder> yeah if it can be scripted you can do anything with script

[04:26:43] <cathode> the slight wobble could be corrected by sanding
[04:26:58] <roycroft> yes, you could true it up easily
[04:27:19] <cathode> ssi - something simple and straightforward like an SNMP trap (if ethernet-connected)
[04:27:27] <roycroft> put a thin coat of paint on it
[04:27:29] <ssi> old school... I like it :)
[04:27:31] <roycroft> sand until all the paint is gone
[04:27:51] <XXCoder> I recall this trick using belt sander you can use pole to hold wheel as you rotate it against belt so distance from shift to wheel is all same
[04:27:52] <cathode> roycroft - yeah i need to balance the wheels too (they'll be running at around ~700 RPM)
[04:28:07] <XXCoder> no idea how to true inside of shaft hole though
[04:28:10] <roycroft> you can do that with a drill
[04:28:18] <cathode> yea
[04:28:33] <roycroft> after it's trued and crowned

[04:29:07] <roycroft> is that wheel made of maple?
[04:29:25] <cathode> the rim is maple and the spokes are hickory
[04:29:38] <roycroft> ok, i was looking at the grain on the rims
[04:29:45] <cathode> warning: do not ever EVER use hickory unless you enjoy being frustrated
[04:29:46] <ssi> ReadError: M100+ codes run shell scirpts
[04:29:47] <ssi> it's pretty easy
[04:30:00] <roycroft> green hickory is fun to work with
[04:30:08] <roycroft> dry hickory is great for firewood
[04:30:24] <cathode> i have mostly carbide cutters on everything in my shop. i can cut 2" hard maple on my table saw without a problem.... cutting 3/4" hickory bogged it down
[04:30:30] <cathode> with a new thin-kerf blade on the TS
[04:31:24] <cathode> the rims of the wheels are made from 3 layers of maple that are overlapping and glued together with urea formaldehyde glue
[04:32:20] <roycroft> are you going to cnc your new bandsaw?
[04:32:26] <cathode> the frame is made from 7 layers of mixed poplar and fir (reclaimed from some remodeling i did to my house) https://dl.dropboxusercontent.com/u/88948814/Shop/Bandsaw/2014-06-08%2013.53.00.jpg

[04:33:00] <cathode> yeah, matthias was my inspiration for this project
[04:33:05] <XXCoder> nice
[04:33:07] <roycroft> the frame looks like it's pretty rigid
[04:33:50] <cathode> but i wanted to go a bit further... i got half a pallet of stuff for free from work last year including a couple boxes of variable frequency drivers
[04:34:22] <cathode> so the bandsaw is currently using a single-phase to 3-phase VFD (1HP) to drive a 3ph 1HP 6-pole motor
[04:35:33] <cathode> VFDs are amazing, i'm assuming most of you in this channel already know that :)

[04:56:29] <XXCoder> not bad idea
[04:56:52] <cathode> if you find someone selling a whole lot of the stuff, often times they have "local pickup only" because they don't know how or don't want to deal with LTL freight shipping

[05:02:17] <cathode> by the way if you order from china... http://www.ebay.com/itm/linear-rail-SBR16-1200mm-4-supporter-rails-8-SBR16UU-blocks-for-CNC-/261002987964?pt=BI_Heavy_Equipment_Parts&hash=item3cc4fd89bc
[05:02:32] <XXCoder> I already has sbr :)
[05:02:54] <cathode> ah
[05:02:56] <zeeshan> you have 575V? :D
[05:02:56] <XXCoder> I theorically has everything (but bolts)

[05:03:51] <XXCoder> sorry about longass url
[05:04:06] <XXCoder> its my latest design, last updated months ago
[05:04:36] <zeeshan> you guys make me want to build a plasma table!

[05:04:57] <XXCoder> this is older design (looks same but yeah lol) but it shows sizes https://scontent-a-sea.xx.fbcdn.net/hphotos-xpf1/v/t1.0-9/10355837_452434954901413_6426483331751996077_n.png?oh=bdf3fa5c0fc2981c3fd8d6e262404d57&oe=54AF1F3F

[05:05:10] <zeeshan> lol
[05:05:13] <zeeshan> i made this design a long time ago
[05:05:21] <zeeshan> before i went to school
[05:05:29] <zeeshan> notice how small my round bar is
[05:05:33] <zeeshan> 1/4" lol
[05:05:36] <zeeshan> er 1/2"
[05:05:37] <XXCoder> fun
[05:05:41] <XXCoder> creaky fun
[05:06:00] <cathode> lol
[05:06:08] <cathode> oversize all the things!
[05:06:11] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/plasmacutter.png
[05:06:12] <XXCoder> cathode: what ya think of my design lol
[05:06:13] <zeeshan> nah
[05:06:21] <zeeshan> you can calculate the deflection based on the weights pretty easily
[05:06:28] <cathode> XXCoder - you know more about CNC stuff than i do but it looks good
[05:06:51] <XXCoder> bit ironic I know about large machines like hurce vm10 than tiny hobby machines
[05:07:01] <XXCoder> I REALLY wish I can run my own jobs
[05:07:14] <zeeshan> XXCoder: have you see the probotix fireball router?
[05:07:24] <XXCoder> I now run large car sized cnc router now.
[05:07:31] <zeeshan> http://probotix.com/FireBall_v90_cnc_router_kit/
[05:07:38] <zeeshan> i was thinking of making mine like that
[05:07:39] <XXCoder> its fairly crappy for company machine but for my home ut'd be kickass.
[05:07:42] <zeeshan> with those plates at the end
[05:07:49] <zeeshan> and round tube where the plates would sit
[05:07:57] <zeeshan> instead of using all that square tubing
[05:08:10] <XXCoder> well probably easier to order
[05:08:28] <zeeshan> suprisingly those ends are plastic
[05:08:30] <zeeshan> on their machine
[05:08:50] <XXCoder> this is machine I use mostly daily now http://www.haascnc.com/we_spec1.asp?id=GR-510&sizeID=120_150INCH_VMC
[05:09:03] <XXCoder> don't buy it.
[05:09:20] <zeeshan> ofcourse
[05:09:22] <zeeshan> its made by haas
[05:09:23] <zeeshan> =P
[05:09:43] <XXCoder> haas has bad rep?
[05:09:51] <Connor> I like the design of my little guy.. http://www.ivdc.com/cnc/cnc8.jpg
[05:09:53] <XXCoder> company I work at mostly use hurcos
[05:09:56] <zeeshan> i have yet to see one haas machine in a production environment
[05:09:59] <zeeshan> by production
[05:10:03] <zeeshan> i mean repetitive production
[05:10:04] <Connor> 12" x 18" x 4.5"
[05:10:11] <zeeshan> like a factory making the same thing over and over
[05:10:36] <XXCoder> that haas is used to make large airplane parts
[05:10:51] <zeeshan> i've seen mazak, dmg, mori seki, emag,
[05:10:54] <zeeshan> im forgetting one name..
[05:10:55] <XXCoder> it has optional air vaccum stuff (boy does that suck)
[05:10:57] <zeeshan> its starts with a m
[05:11:05] <XXCoder> mastercam? heh jk
[05:11:06] <zeeshan> matsuura
[05:11:10] <cathode> at my workplace we have a Euromac turret punch, because we deal exclusively with sheet goods
[05:11:15] <zeeshan> i meant to say matsuura not mazak
[05:11:32] <XXCoder> Connor: yea thats decent design
[05:11:38] <XXCoder> bet mine'd be worse lol
[05:11:52] -!- ve7it has quit [Remote host closed the connection]
[05:11:56] <XXCoder> you saw my design
[05:12:04] <Connor> btw, if you thinking of using 80/20 Look at these people.. http://www.misumiusa.com/
[05:12:08] <zeeshan> you guys really like your wood!
[05:12:16] <XXCoder> hey dont touch my wood
[05:12:34] <Connor> zeeshan: Built with a Table saw and a hand drill.. All I'm saying..
[05:12:40] <zeeshan> connor hehe :P
[05:12:52] <zeeshan> theres nothing wrong with wood designs
[05:12:56] <zeeshan> i will just set it on fire with the plasma
[05:13:10] <XXCoder> heh
[05:13:13] -!- jerryitt has quit [Quit: Connection closed for inactivity]
[05:13:13] <Connor> There is a reason it's a Router and Not a plasma..
[05:13:31] <zeeshan> the main reason i dont like wood is
[05:13:31] <XXCoder> im stuck between hyrid 80/20/wood and just wood
[05:13:33] <zeeshan> its sensitivity to humidity
[05:13:35] <XXCoder> probably go just wood
[05:13:45] <zeeshan> depending on the day, your hole will be in a different position :P
[05:14:13] <XXCoder> actually depend on wood
[05:14:21] <XXCoder> laminated wood isnt that sensive
[05:14:36] <XXCoder> mdf probably not that sensive
[05:14:41] <XXCoder> I dont plan to use mdfg
[05:14:58] <cathode> i hate machining mdf
[05:15:05] <cathode> fine powdery awful dust EVERYWHERE
[05:15:11] <zeeshan> wood doesnt belong in precise applications :P
[05:15:17] <XXCoder> cat just dont start fire
[05:15:21] <Connor> Yup.. Vacuum hooked up.. and wear a mask
[05:15:25] <XXCoder> in case it becomes fuel-air bomb
[05:16:16] <roycroft> my router will be 80/20 and aluminium plate
[05:16:41] <XXCoder> man I really wish theres local source of 80/20
[05:16:52] <zeeshan> automation stores carry it
[05:16:55] <XXCoder> seemly everyone can get em from local areas but me lol
[05:17:02] <roycroft> i don't have a local source
[05:17:05] <Connor> Look at the misumi stuff.. It's way cheaper.. http://us.misumi-ec.com/vona2/mech/M1500000000/M1501000000/M1501010000/
[05:17:14] <zeeshan> and last time i checked
[05:17:20] <zeeshan> 80/20 has a pretty bad tolerance
[05:17:23] <zeeshan> over a linear foot
[05:17:36] <zeeshan> again depending on what you want to do with it
[05:17:52] <XXCoder> im fine with .001" tol
[05:18:03] <XXCoder> its not like im making high precision sruff
[05:18:07] <zeeshan> thats straightness prolly
[05:18:10] <zeeshan> but flatness i think was 5 thou
[05:18:21] <Connor> It's not going to make any difference.. You tram it all out and mill down a spoil board using the machine itself.
[05:18:22] <zeeshan> thats why i looked at just getting regular profile
[05:18:24] <zeeshan> and machinig it flat
[05:18:51] <zeeshan> when your screw binds
[05:18:53] <zeeshan> it'll make a difference :P
[05:19:08] <XXCoder> Connor: I tend to refuse to buy from sites that dont display prices before login
[05:19:31] <Connor> XXCoder: It's worth making a login for.. I normally agree.. but, in this case.. it is worth it.
[05:19:54] <roycroft> i normally don't do that, either
[05:19:55] <Connor> 15x15mm 2 Meter long extersion for $7.10
[05:19:57] <XXCoder> lot cheaper than 80/20?
[05:20:08] <XXCoder> a sec
[05:20:08] <roycroft> i can make up email addresses at the drop of a hat though
[05:20:10] <Connor> Yea.. 30-40% cheaper.
[05:20:12] <roycroft> and can delete them even faster
[05:20:16] <zeeshan> roycroft: lol
[05:20:16] <zeeshan> :D
[05:20:17] <roycroft> so i make exceptions
[05:20:19] <XXCoder> half inch
[05:20:38] <XXCoder> well .6" basically
[05:20:39] <Connor> That was what I used for my enclosure on the G0704.
[05:20:54] <ssi> 15mm is VERY flimsy
[05:20:55] <Connor> They have metric profiles.. 15, 20, 40 etc
[05:21:09] <Connor> ssi: Like I said, it was for the frame of the enclsoure.
[05:21:12] <ssi> yeah I know
[05:21:13] <Connor> enclosure.
[05:21:15] <ssi> it's fine for that
[05:21:20] <ssi> but XXCoder is talking about making a machine frame
[05:21:23] <zeeshan> http://www.8020.net/design-tools-26.asp
[05:21:24] <XXCoder> yeah
[05:21:28] <zeeshan> i'd use those tools..
[05:21:32] <zeeshan> deflection calculator..
[05:21:33] <ssi> I need to go back and replace the legs of my laser with 40x40 double extrusion or something
[05:21:41] <Connor> Right. I was giving him a price of what I had purchased and knew about.
[05:21:48] <zeeshan> ssi gusset it :P
[05:21:50] <XXCoder> well getting late night :)
[05:22:00] <ssi> it's already gusseted
[05:22:02] <XXCoder> zee invent anti-grav
[05:22:03] <zeeshan> pics
[05:22:14] <ssi> not now
[05:22:15] <XXCoder> err ssi I mean lol
[05:22:16] <roycroft> i'm planning on making a stand for my router out of 3"x1/4" square steel tubing
[05:22:24] <XXCoder> anyway night!
[05:22:29] <zeeshan> roycroft: that's what im talking about
[05:22:31] <zeeshan> !!! :D
[05:22:34] <roycroft> and mounting the 80/20 frame right on top of that
[05:22:44] <zeeshan> you know that stuff is expensive though? :/
[05:22:49] <roycroft> i don't think i'll have deflection problems with that
[05:22:50] <roycroft> yes
[05:22:58] <zeeshan> what size router
[05:23:00] <roycroft> making crappy tools is more expensive
[05:23:05] <ssi> eh 3"x3"x1/4" steel is a lot cheaper than 8020
[05:23:08] <roycroft> 2'x3'x8"
[05:23:15] <zeeshan> ssi lies
[05:23:30] <zeeshan> well if youre comparing it with 3x3" 8020
[05:23:32] <zeeshan> yes
[05:23:40] <ssi> I built my plasma table out of 4x2x3/16" and it was maybe $400 for all the steel
[05:24:03] <roycroft> i was thinking about 1.5"x3" 80/20 for the base frame
[05:24:18] <zeeshan> shit gets heavy fast
[05:24:29] <zeeshan> ssi i think 3x3x.25 locally
[05:24:34] <zeeshan> for 1 length (20 foot)
[05:24:35] <roycroft> the 3" steel tubing is going to be pretty damn heavy
[05:24:42] <zeeshan> is easily 300$
[05:24:47] <Connor> 25mm x 25mm x 4000mm $68.00
[05:25:08] <zeeshan> nm
[05:25:11] <zeeshan> 220$
[05:25:17] <ssi> heavy is good
[05:25:21] <roycroft> and i'll need about 1 length of tubing for the base
[05:25:22] <ssi> zeeshan: that's insane
[05:25:26] <roycroft> er, stand
[05:25:32] <ssi> I buy full boat retail from metal supermarket and it's much cheaper than that
[05:25:37] <cathode> depends... for a router table, heavy is good (absorb vibration). for a plasma i dont know that it'd matter much
[05:25:44] <zeeshan> we're talking about .25"!!

[05:27:02] <ssi> you said 300
[05:27:03] <ssi> :P
[05:27:05] <ssi> revisionist
[05:27:11] <zeeshan> er 220
[05:27:18] <roycroft> online metals is high retail
[05:27:24] <roycroft> i get my metal locally for less than that
[05:27:33] <ssi> http://www.mcmaster.com/#47065t109/=uaasu8
[05:27:33] <zeeshan> yea its usually 50% of online metals
[05:27:45] <ssi> mcmaster is $100 for 8' of 1.5x3" 8020
[05:27:49] <zeeshan> the one thing i like about square tube
[05:27:55] <zeeshan> or tube in general is you can fill it up with sand
[05:28:02] <zeeshan> and get even more damping
[05:28:04] <roycroft> or granite epoxy
[05:28:11] <zeeshan> me like sand
[05:28:14] <zeeshan> fine sand
[05:28:17] <ssi> granite epoxy would probably be easier to do with C channel
[05:28:25] <zeeshan> the sand particles rub with each other for ultimate damping
[05:28:25] <Connor> Wow. $15.80 for 2 meters of 25mm x 25mm
[05:28:58] <zeeshan> usually people do granite epoxy in non enclosed sections
[05:29:03] <zeeshan> cause it's easier
[05:29:11] <roycroft> well i'm going to be a good engineer and fully design this router before i buy any more components
[05:29:17] <roycroft> and also do a cost estimate
[05:29:37] <zeeshan> roycroft: or you can hax one up like 80% :P
[05:29:38] <roycroft> i built a new brewing system earlier this year without doing the complete design up front and without a budget
[05:29:44] <roycroft> i guestimated it would cost about $4k
[05:29:48] <roycroft> it came in well over $6k
[05:29:54] <Connor> $69.00 for 40mm x 80mm x 2000mm
[05:29:55] <ssi> that's always the way
[05:29:59] <roycroft> i almost fired myself for that
[05:30:04] <roycroft> but instead i made some good beer :)
[05:30:53] <zeeshan> someone take a piece of square tube
[05:30:58] <zeeshan> and stuff it with granite epoxy
[05:30:59] <zeeshan> and one with sand
[05:31:04] <roycroft> i'm actually a really good estimator, when i take the time to do it
[05:31:13] <zeeshan> and bang it with a accelrometer hammer
[05:31:17] <zeeshan> and report back with results!
[05:31:18] <roycroft> that would be an interesting experiment, zeeshan
[05:31:32] <zeeshan> i'm really curious to see the differnce
[05:31:35] <zeeshan> internets isnt coming up with anything
[05:31:45] <zeeshan> ive used sand bags before and tested in a school experiment
[05:31:47] <zeeshan> vs gussets
[05:31:49] <roycroft> that's because there are no cats involved in the experiment
[05:31:57] <zeeshan> haha
[05:32:18] <roycroft> fill a cat with sand
[05:32:24] <roycroft> and fill another cat with granite epoxy
[05:32:29] <roycroft> then conduct the experiment
[05:32:41] <zeeshan> hahaha
[05:32:59] <roycroft> you will own the internet for 15 minutes
[05:34:45] <zeeshan> i remember when i was designing the round rails
[05:34:55] <zeeshan> i was suprised at how much 1/2" round bar deflects
[05:35:02] <zeeshan> under 100lb of load if you load it right at the center
[05:35:12] <zeeshan> of a 36" simply supported span
[05:35:19] <zeeshan> its a floppy noodle
[05:37:16] <roycroft> angle would deflect a lot less
[05:37:26] <roycroft> and square tubing is two pieces of angle
[05:40:30] <zeeshan> deflection_max = Pl^3 / (48EI ) = (100*36^3)/(48*30e6*(pi/64)*(0.5)^4) = 1.06 in
[05:40:31] <zeeshan> hm
[05:40:33] <zeeshan> something seems off :P
[05:40:50] <zeeshan> 100lb, steel, round bar .5"
[05:41:14] <zeeshan> okay i guess its right
[05:41:17] <zeeshan> it deflects 1.06"
[05:41:27] <zeeshan> 1" round bar deflects 0.066"
[05:41:43] <zeeshan> 2" bar deflects 0.004"
[05:41:44] <zeeshan> hmm
[05:41:54] <zeeshan> i dont believe these numbers :p
[05:44:45] <roycroft> so, using 1530, at 36" length fixed at both ends, a 35lb load in the center will deflect 0.0005"
[05:44:47] <roycroft> that's not bad
[05:45:32] <roycroft> a 100lb load would only deflect 0.0014"
[05:45:39] <zeeshan> where is my formula wrong
[05:45:54] <zeeshan> 1" is way too much
[05:46:03] <roycroft> that seems a bit much

[06:17:39] <zeeshan> they were gone in like 1hour of the posting
[06:17:41] <zeeshan> such bs
[06:19:44] <zeeshan> archivist: have you seen the patek philippe watch making video
[06:19:49] <zeeshan> for the 2.5 million dollar watches?
[06:19:52] <zeeshan> that they made like 7 of
[06:20:25] <zeeshan> http://www.youtube.com/watch?v=SGPjFFMD3c0
[06:20:26] <zeeshan> that one
[06:20:41] <zeeshan> i noticed a lot of tools in there
[06:20:43] <zeeshan> that you have :)

[06:25:47] <guerillaengineer> Ooh
[06:27:33] <guerillaengineer> Anyone here?
[06:28:56] <zeeshan> no
[06:29:07] <guerillaengineer> GOOD
[06:34:27] <guerillaengineer> I'm just messing, what's up?
[06:37:04] <ssi> ok I managed to burn up a whole 24x36" sheet of acrylic
[06:37:07] <ssi> moving on to silicone
[06:37:17] <ssi> made about 750 caps, I can get 1000 gaskets out of the silicone I have on hand
[06:37:57] <guerillaengineer> What was your relative RPM set at?
[06:38:35] <guerillaengineer> Oh crap, were you speaking of a laser cutter? I thought you meant you ruined an entire sheet.
[06:38:40] <ssi> yeah, laser
[06:38:50] <ssi> didn't ruin anything
[06:39:01] <ssi> amazing for me, I know
[06:39:01] <guerillaengineer> Geez, what's your wattage for the laserhead?
[06:39:23] <ssi> 120W max, but I'm only running about 50W for the acrylic and 20W for the silicone
[06:40:18] <guerillaengineer> That's nice, so you're slicing like 1/4inch?
[06:40:48] <ssi> yep
[06:40:56] <guerillaengineer> Pimpin', sir.
[06:42:00] <ssi> I have a long way to go :P
[06:42:12] <ssi> ~5000 parts this weekend, and another 20,000 in the weeks to follow
[06:42:31] <guerillaengineer> Holy christ, someone's busy.
[06:43:06] <ssi> heh yeeah
[06:44:14] <guerillaengineer> Question: Are you cutting seals and then slicing the excess for the gaskets? My brother used to do that and just sell the smaller sizings at a discounted rate.
[06:44:38] <ssi> nah these gaskets are about the same dimensions as the cap, and no waste
[06:44:51] <guerillaengineer> That's even better.
[06:45:05] <ssi> there's almost no waste in this project... love it
[06:45:15] <ssi> https://pbs.twimg.com/media/B0rVVuWIAAErD-P.jpg:large
[06:45:45] <guerillaengineer> *whistles* That is so efficient.
[06:46:07] <ssi> .007" kerf, and the kerfs overlap
[06:46:39] <ssi> I'm getting 750 parts from a 24x36" sheet of acrylic
[06:46:57] <guerillaengineer> That's impressive modeling, have you been in the fabrication business long?
[06:47:23] <ssi> it's not really my primary line of work, but I've done side work in fabrication for about a decade

[06:49:56] <guerillaengineer> Woah. That's why I'm getting into cnc/laser/3d building. Haha, I'm driving myself mad with my first build currently.
[06:50:04] <ssi> what are you working on?

[06:50:43] <zeeshan> har har har
[06:50:44] <ssi> hahah
[06:50:51] <ssi> gotta start somewhere :)
[06:51:07] <ssi> there's a lot of bootstrapping in this hobby
[06:51:21] <ssi> and you'll find yourself going down the rabbit hole of building tools to help you build tools
[06:51:46] <guerillaengineer> That's what got me here! I do a lot of pcb fabbing, along with "hand" engineering.

[07:12:25] <ssi> zeeshan: I'm making money! what's your excuse
[07:12:41] <zeeshan> studying this retardedly hard math for the exam on wednesday
[07:12:44] <zeeshan> this prof is.. ugh
[07:12:48] <zeeshan> he talks about this stuff casually
[07:12:50] <zeeshan> doesnt teach it
[07:13:31] <archivist> often they dont know it themselves
[07:13:39] <zeeshan> he does
[07:13:44] <zeeshan> he just sucks at teaching
[07:13:52] <zeeshan> its a graduate course, and its his speciality
[07:13:54] <zeeshan> so he better know it
[07:14:00] <guerillaengineer> I built a ballistics-style soundproof enclosure especially for this machine. @zeeshan I feel you, my bio-chem reactions prof is a very lazy guy.
[07:14:01] <zeeshan> he's been able to answer any question i ask him
[07:14:33] <zeeshan> he told us
[07:14:40] <zeeshan> in the 3 hours we have for the test, we will not be finishing it
[07:14:50] <zeeshan> the test would take us 9 hours to finish if we knew what we were doing
[07:14:58] <guerillaengineer> Wow
[07:14:59] <zeeshan> so WHAT is the point of asking that many questions?!?!?!
[07:15:12] <zeeshan> he told us, he wants to see who can finish the most
[07:15:16] <zeeshan> and grade them accordingly.
[07:15:16] <archivist> see if you know the methods
[07:15:40] <guerillaengineer> Tell him to be like a plotting machine, go too fast and you miss STEPS
[07:15:53] <zeeshan> dude if i had my computer
[07:15:54] <zeeshan> and matlab
[07:15:56] <guerillaengineer> I humor myself.
[07:15:58] <zeeshan> i could answer some of these questions really fast
[07:16:07] <zeeshan> but don't expect me to reduce a 16x16 matrix
[07:16:10] <zeeshan> in less than an hour
[07:16:12] <zeeshan> it takes a while.
[07:16:22] <guerillaengineer> What is the course?
[07:16:51] <zeeshan> "advanced structural mechanics"
[07:17:25] <zeeshan> basically its an extension of undergrad w/ some more advanced concepts
[07:17:32] <guerillaengineer> for DFI data structures?
[07:17:40] <zeeshan> like when doing torsion, in undergrad you stop at tau = tr / j
[07:17:53] -!- Mr_Sheesh has quit [Max SendQ exceeded]
[07:18:07] <zeeshan> in this coarse you talk about st venants torision (pure torsion)
[07:18:13] -!- koo6 [koo6!~sirdancea@98.82.broadband5.iol.cz] has joined #linuxcnc
[07:18:15] <zeeshan> which is unrestrained torsion
[07:18:18] <archivist> compression buckling of long thin stuff was timishenko iirc
[07:18:42] <guerillaengineer> Is... is that funny?
[07:18:44] <zeeshan> archivist: depends on the ratio of height to width
[07:18:50] <zeeshan> theres like 4 different theories
[07:19:04] -!- The_Ball has quit [Ping timeout: 265 seconds]
[07:19:06] <archivist> but wasnt he one of the first in that area
[07:19:06] <zeeshan> i haven't looked at it from theory of elasticity method
[07:19:23] <zeeshan> timshenko's methods are usually fron a boundary value perspective
[07:19:25] <guerillaengineer> Vlasov, yo.
[07:19:30] <zeeshan> he identies the boundary conditions
[07:19:38] <zeeshan> and identifies a partial differential equation that relates the system
[07:19:47] <zeeshan> so his solutions are way more accurate than using simple mechanics
[07:20:05] <zeeshan> so in undergrad we find out torsional stress = T * R / J
[07:20:11] <zeeshan> but in this course, he extends it to warping
[07:20:23] <zeeshan> basically if you roll up a piece of paper, and you torque it after
[07:20:28] <guerillaengineer> So you already learned shear stresses, right?
[07:20:29] <zeeshan> you'll not only that it develops shear
[07:20:45] <guerillaengineer> Ha, got my answer.
[07:20:48] <zeeshan> but the ends of the paper go in and out axially
[07:20:54] <archivist> I was working out a roll bend, then I noticed the simple mechanics are wrong, simple arc!
[07:21:16] <zeeshan> simple mechanics won't deal with plasticity too often
[07:21:33] <zeeshan> most of the theories assume linear relationship betwen stress and strain (hookes law)
[07:21:34] <archivist> this was in the elastic region
[07:21:37] <zeeshan> o
[07:21:53] <zeeshan> there is a lot of assumptions, gotta be careful
[07:22:01] <archivist> verily
[07:22:07] <zeeshan> like take a simple example
[07:22:10] <zeeshan> you have a hole in a plate..
[07:22:15] <zeeshan> and you stretch it axially
[07:22:25] <zeeshan> if you try to use simple mechanics to solve the problem near the hole
[07:22:28] <zeeshan> you'll get a completely wrong answer
[07:22:35] <zeeshan> but itll be valid far away from the hole
[07:22:57] <zeeshan> so they bring in fudge factors like stress concentration factor of hole
[07:23:09] <zeeshan> which has been found from theory of elasticity (timenshenko)
[07:23:12] <zeeshan> or FEA
[07:23:21] <zeeshan> or experiment :P
[07:23:34] <zeeshan> i hate this class because of how fast he goes
[07:23:37] <zeeshan> and how little he teaches
[07:24:03] <guerillaengineer> I can see it, man. That would be hell.
[07:25:03] <zeeshan> archivist: i dont know if you know this
[07:25:09] <zeeshan> but in 99% of undergrad
[07:25:15] <zeeshan> we dealt with isotropic materials only
[07:25:42] <guerillaengineer> ssi: You still around?
[07:25:45] <ssi> yep
[07:25:49] <zeeshan> okay enough talking about this
[07:26:13] <guerillaengineer> I was wondering if you could solve a hella problem for me? You seem to be quite adept in this field.
[07:27:10] <ssi> well I dunno
[07:27:35] <ssi> lay it on me
[07:27:42] <archivist> just ask there a plenty to reply at certain times of the day
[07:28:20] <guerillaengineer> I cannot find a driver/breakboard/controller/power supply setup that doesn't break my bank
[07:28:31] <guerillaengineer> I've been researching for 17 straight hours

[07:29:15] <guerillaengineer> I did, the hg7881 (l9110s)
[07:29:15] <ssi> zeeshan knows what I'll recommend :P
[07:29:15] <ssi> but it's probably more money than you'd want to spend
[07:29:15] <guerillaengineer> but it is so underpowered
[07:29:15] <zeeshan> ssi is an amc lover
[07:29:16] <zeeshan> :-)
[07:29:16] <ssi> no, not for this
[07:29:23] <zeeshan> oh keling drives
[07:29:24] <ssi> leadshine drives, mesa for everything else
[07:29:28] <ssi> yea keling/leadshine
[07:29:30] <ssi> same thing
[07:29:44] <zeeshan> honestly if i'd go back
[07:29:47] <zeeshan> i'd prolly do mesa on the lathe too
[07:29:55] <zeeshan> i might in the future
[07:29:58] <zeeshan> when i throw a tool changer on it
[07:30:01] <zeeshan> if i ever decide to
[07:30:13] <zeeshan> the kit looks simple enough to install
[07:30:18] <ssi> it's worth it
[07:30:32] <zeeshan> ssi
[07:30:38] <zeeshan> why do you think i cant get more than 150 iupm
[07:30:41] <zeeshan> without losing steps?
[07:30:47] <zeeshan> with the 1200oz-in motors
[07:30:55] <guerillaengineer> Ah, I've seen these. It's just that outside of having the stepper motors I only have like 100 bucks (I plan on allocating a serial-setup PC PS for a power supply, probably
[07:30:57] <ssi> big motors are slow
[07:31:11] <zeeshan> okay so its not a hardware limit
[07:31:12] <ssi> maybe insufficient voltage
[07:31:13] <zeeshan> it is a stepper limit
[07:31:18] <zeeshan> im giving them 65VDC
[07:31:19] <ssi> might be a hardware limit
[07:31:23] <ssi> there's no way for me to know :)
[07:31:39] <archivist> guerillaengineer, serial? er no
[07:31:41] <zeeshan> its not a hardware limit
[07:31:47] <zeeshan> cause the x drive is 3:1
[07:31:50] <zeeshan> while z is 1:!
[07:31:55] <guerillaengineer> I meant parallel, I am so burned out
[07:31:57] <zeeshan> i can push z to 150ipm
[07:32:01] <zeeshan> but i cant push x more than 100 ipm
[07:32:14] <zeeshan> 125 ipm, it loses steps
[07:32:18] <ssi> that means you're running x twice as fast
[07:32:27] <zeeshan> 3x

[07:32:42] <zeeshan> yes
[07:32:46] <ssi> twice as fast
[07:32:54] <zeeshan> 3:1 ratio??
[07:32:54] <ssi> if x were 1:1, you'd be getting 300ipm

[07:33:45] <ssi> besides, nobody needs that kind of speed
[07:33:48] <zeeshan> makes sense
[07:33:52] <ssi> keep it under 100ipm, whippersnapper

[07:34:18] <ssi> with 900ipm rapids
[07:34:21] <zeeshan> :D
[07:34:21] <ssi> and it's still too slow :(
[07:34:41] <zeeshan> i dont know this
[07:34:42] <ssi> the gaskets look like they'll be about 1:15 for 500 parts
[07:34:44] <zeeshan> but does a laser cutter need thc
[07:34:49] <ssi> no
[07:35:09] <ssi> I mean, if it had some way to maintain very accurate focus height that would be cool, but most don't
[07:35:19] <ssi> most in the class of my machine anyway
[07:35:25] <ssi> big metal lasers might do something like that
[07:35:30] <ssi> cause they likely have similar issues to plasma
[07:35:38] <zeeshan> im trying to remember the one at eaton
[07:35:41] <ssi> but the mechanism would have to be different
[07:35:42] <zeeshan> i vaguely remember something about focus
[07:35:44] <zeeshan> based on sheet size
[07:35:48] <ssi> plasma thc works by sensing arc voltage
[07:35:51] <guerillaengineer> Hold up, I can hook up this 75w carbon laser system to a cnc body. Holy crap, I am retarted.

[07:41:09] <ssi> or the HR/OC mirrors
[07:41:16] <ssi> CO2 lasers are simple
[07:41:31] <ssi> a 1kw co2 tube would be enormous though if it were straight line

[07:42:23] <ssi> yeah that'd be folded
[07:42:28] <guerillaengineer> If you had correct diodes array
[07:42:46] <zeeshan> correct me if im wrong
[07:42:50] <zeeshan> but you have a tube filled with co2
[07:42:51] <guerillaengineer> I am building a cnc to cover my arrays and mirroring
[07:42:54] <zeeshan> you shoot some electrons at it
[07:43:03] <zeeshan> and it releases photons?

[07:43:56] <zeeshan> what makes the laser tube so long
[07:43:59] <zeeshan> like 7 feet
[07:44:06] <ssi> it's a resonator
[07:44:33] <ssi> it's like if you want more output from a subwoofer, you need a bigger box
[07:44:34] <ssi> :)
[07:44:56] <guerillaengineer> You don't want to put that much power through a short housing without a VERY-high concentration with some magical shielding gas that doesn't exist yet

[07:45:03] <zeeshan> put em in series
[07:45:07] <zeeshan> and get 1kW? :D
[07:45:13] <guerillaengineer> It'd blow like crazy

[08:07:31] <ssi> that's what I've always used
[08:07:54] <guerillaengineer> someone told me 32xsqrt(mH)
[08:08:01] <gonzo_> on ebay the 7 odd amp 80V drivers are only around £40
[08:08:18] <ssi> gonzo_: the leadshine ones?
[08:08:34] <gonzo_> not sure of the make
[08:08:52] -!- tronwizard [tronwizard!tronwizard@] has joined #linuxcnc
[08:09:58] <ssi> guerillaengineer: you could take a 24VAC transformer, rectify and filter it and make a nice ~32VDC unregulated supply
[08:10:07] <ssi> use that to feed those KL4030 drives, and have a nice matched setup for those motors
[08:10:26] <guerillaengineer> I'll go pick up a UPS tomor-today
[08:10:38] <guerillaengineer> I love the transformers in those.
[08:10:44] <ssi> neat idea
[08:11:24] <guerillaengineer> Those kl4030s, I'll need one for each motor, wont I?
[08:11:28] <ssi> yeah
[08:11:36] <ssi> you MIGHT could get away with one for the gantry
[08:11:38] <guerillaengineer> Yeesh
[08:11:45] <ssi> assuming you're trying to build a laser
[08:12:02] <gonzo_> I have some ebay 261421509107 ones. Thoiugh they were £39 each when I brought mine
[08:12:05] <ssi> yeah that'd probably work fine actually
[08:12:08] <ssi> your motors are 1.5A
[08:12:14] <ssi> you could wire both in parallel on one drive
[08:12:16] <ssi> they're 4A drives
[08:12:25] <guerillaengineer> That's the thing, i'm building a crappy proto so I can mill better parts for a better cnc, which I will use to create my lasers
[08:12:38] <guerillaengineer> Oh, that's awesome
[08:12:49] <ssi> yea, but that won't work for a 3axis machine
[08:12:55] <ssi> you'll need three drives
[08:13:00] -!- quiqua has quit [Quit: quiqua]

[08:13:26] <ssi> it's not my favorite way to do things
[08:13:28] <ssi> but it's feasible
[08:13:43] <ssi> bear in mind you can't do anything independent with the gantry motors if you go that route
[08:13:47] <ssi> like independent homing
[08:13:55] <ssi> but apparently I'm the only person in the world who wants that anyway :)
[08:14:45] <guerillaengineer> Independant homing? For moving Y1 and Y2 (assuming Y1 and Y2 are the ends of the Y-axis) seperately for better tracking?
[08:15:17] <ssi> they move together during normal operation, but when the axes home, they move at the same time but find separate home switches and have separate offsets
[08:15:26] <guerillaengineer> Oh thanks the gods, I just imagined your machine ripping it's own neck off
[08:15:26] <ssi> for auto-squaring the gantry
[08:15:35] <guerillaengineer> That's a very neat idea
[08:15:35] <ssi> yeah it tries sometimes :)
[08:15:46] <ssi> fortunately the motors aren't strong enough to hurt anything
[08:15:52] <ssi> the nice thing about that is
[08:15:58] <ssi> I can take a long test cut, and check it for square
[08:16:02] <ssi> and ajdust out any error
[08:16:06] <ssi> by tweaking the home offsets
[08:16:36] <guerillaengineer> And you say you're doing this as a hobby? Because that's a professional idea if I've ever seen one.
[08:16:52] <ssi> it's not a popular idea for whatever reason
[08:17:04] <ssi> it's not supported in vanilla linuxcnc
[08:17:22] <ssi> we're working toward it; there's an active branch that makes provisions for it
[08:17:24] <guerillaengineer> Probably budgetary concerns/laziness. I'm going to calculate algorithms for linuxcnc
[08:17:35] <guerillaengineer> Because that sounds useful as hell

[08:17:56] <ssi> the laser, and a 50x50" plasma table

[08:18:27] <ssi> that was the first machine I built actually
[08:18:30] <ssi> like six years ago
[08:19:05] <guerillaengineer> You made hella money with that, didn't you?
[08:19:11] <ssi> no, I wish
[08:19:20] <guerillaengineer> Whaaat
[08:19:21] <ssi> I'm typically not very good at selling my services
[08:19:24] <ssi> heh
[08:19:42] <guerillaengineer> That's going to be my problem as well
[08:19:57] <ssi> the plasma table still doesn't work as well as I'd like it to
[08:20:07] <guerillaengineer> "Come buy things from a 24 year old crippled guy made from his living room!"
[08:20:11] <ssi> and I don't like trying to get jobs unless I'm very confident in my work

[08:21:08] <ssi> sounds like a lot of work for something fairly inexpensive :)
[08:21:45] <guerillaengineer> That doesn't look bad at all! What's your coolant system running? And He is doing it for free, (I'm a HUGE teacher's pet)
[08:22:00] <ssi> this vid was from before I did a bunch of rework on the machine
[08:22:12] <ssi> it has a proper machine torch now, and my water table is now self-filling/draining
[08:22:19] <ssi> the coolant is homemade plasma quench
[08:22:22] <guerillaengineer> That's potential, right therer
[08:22:28] <ssi> now I have a 55gal plastic drum under the table
[08:22:33] <guerillaengineer> Homemade, eh? Neat.
[08:22:37] <ssi> and 10psi of shop air will displace it into the table
[08:23:01] <guerillaengineer> That's a good idea, silent air compressor?
[08:23:11] <ssi> definitely not silent
[08:23:29] <guerillaengineer> Haha, I have a little silent one. Hate the loud ones
[08:23:36] <ssi> mine's not too loud as they go
[08:23:46] <ssi> it's a 5hp IR 18cfm oiled machine
[08:23:51] <guerillaengineer> I may do a plasma cutter with servo-driven ceramic leading arms
[08:24:02] <ssi> I don't know what you mean
[08:24:40] <guerillaengineer> Like, a tesseract-motion system. (four arms leading the torch)
[08:24:47] <guerillaengineer> Ceramic only for grounding purposes
[08:24:54] <ssi> hm, like a delta arm?
[08:25:07] <guerillaengineer> yeah! But horizontal and four of them
[08:25:10] <ssi> gotcha
[08:25:28] <guerillaengineer> I bet with the proper servos it'd be hella efficient.
[08:26:30] <ssi> probably
[08:27:16] <guerillaengineer> I seriously made couplings out of nylon spacers cut down and hooke up to vinyl tubing with a hex screw. I didn't want to use backlash nuts
[08:27:34] <ssi> I've done plenty of stuff like that
[08:27:41] <guerillaengineer> I live up to "guerillaengineer" as much as possible.
[08:28:03] <ssi> I built a little desktop machine and I took some acme screw, cut flutes in it to make a tap, and tapped a piece of delrin to make a homemade leadnut
[08:28:16] <guerillaengineer> flutes?
[08:28:23] <ssi> yeah like the flutes in a tap
[08:28:33] <ssi> just cut it with an endmill to give it "teeth"
[08:28:41] <guerillaengineer> Ohhh
[08:28:42] <ssi> homemade acme tap
[08:29:13] <guerillaengineer> Like, cutting the end for a better grip?
[08:29:29] <ssi> lemme see if I can find a picture
[08:30:07] <guerillaengineer> I found a youtube video
[08:30:28] <ssi> couldn't find a pic of the tap, but here's a pic from the era

[08:30:36] <ssi> taht's how my plasma Z axis started out
[08:30:43] <ssi> that's a homemade delrin leadnut
[08:31:01] <ssi> all of that's homemade actually except the rails and the screw
[08:31:07] <ssi> and the bearings and lovejoy coupler :P
[08:31:13] <ssi> ...and fasteners :)
[08:31:27] <guerillaengineer> I never thought of that
[08:31:53] <guerillaengineer> Yeah, I just pulled ABEC 7s from rollerblades
[08:32:03] <guerillaengineer> a little heat-shrink tubing and bam
[08:32:10] <ssi> I've used a ton of skate bearings :P
[08:32:34] <guerillaengineer> It's so good to know that I am not the only one that has ghetto-rigged parts
[08:33:17] <ssi> heh lots of us in here do
[08:33:37] <guerillaengineer> Do you think this would be sufficient in terms of a VAC transformer?

[08:34:00] <ssi> too small
[08:34:13] <guerillaengineer> Darn
[08:34:26] <ssi> if you're gonna run three motors at 32VDC, 1.5A apiece, I'd want to see at least 100VA
[08:34:38] <guerillaengineer> I thought 40 looked paltry
[08:34:53] <guerillaengineer> It was so cheap though ;-;
[08:35:12] <ssi> actually probably more like 200VA
[08:35:24] <ssi> 24VAC transformers should be easy to scavenge
[08:35:26] <ssi> they're very common
[08:35:40] <guerillaengineer> Oh yeah, the UPS
[08:36:01] <guerillaengineer> And one of these, rectified and filtered, can run three motors at 4amp?
[08:36:37] <guerillaengineer> Well, 3.5, with overhead?
[08:36:47] <ssi> 4.5A with overhead
[08:36:58] <guerillaengineer> Even better
[08:37:04] <ssi> 6A of current capacity out of your power supply should be a good target to shoot for
[08:37:24] <guerillaengineer> I'm going to need THICK rubber gloves.
[08:37:26] <ssi> look for a 24VAC transformer at least 200VA and I think you'll be happy
[08:37:36] <ssi> gloves?
[08:37:45] <guerillaengineer> I'm glad I have bigass capacitors lying around
[08:38:09] <guerillaengineer> I have a fear of electrocution.
[08:38:12] <ssi> ah
[08:38:30] <ssi> but you play with lasers? :)
[08:38:40] <ssi> the laser psu is the only electricity that actively scares me
[08:38:44] <guerillaengineer> Yeah, apparently Muscular Dystrophy and being struck by lightning don't mix well.
[08:39:00] <ssi> my laser supply is 35kV, 40mA
[08:39:03] <ssi> gives me the willies
[08:39:06] <guerillaengineer> I can test lined supplies without any active current though

[12:17:22] <Bearded_Comrade> yo?
[12:17:35] <guerillaengineer> Sorry, herr comrade. Hi.
[12:17:42] <Bearded_Comrade> Hey
[12:17:52] <guerillaengineer> What's up on your end?
[12:17:56] <Bearded_Comrade> not much
[12:18:00] <Bearded_Comrade> midterm exams
[12:18:05] <guerillaengineer> Same.
[12:18:17] <guerillaengineer> Well, next week.
[12:18:24] <Bearded_Comrade> last one today for me
[12:18:39] <guerillaengineer> Right on, you confident?
[12:19:06] <Bearded_Comrade> no
[12:19:19] <Bearded_Comrade> this is the midterm where the class average is like 25%
[12:19:26] <guerillaengineer> Aww, c'mon herr comrade. What's the course?
[12:19:40] <Bearded_Comrade> Sensors and Instrumentation
[12:19:47] <Bearded_Comrade> its that the prof kinda sucks
[12:19:51] <Bearded_Comrade> doesnt teach anything
[12:20:05] <Bearded_Comrade> and if he mentions it in passing, you should know it
[12:20:23] <guerillaengineer> ocrap.jpeg, that sucks. My biochem reactions prof sucks as well

[12:21:51] <guerillaengineer> What's your major?
[12:22:02] <Bearded_Comrade> mechatronics
[12:22:10] <guerillaengineer> Whaaat, that's awesome
[12:22:20] <guerillaengineer> Are you going to build the Sentinels?
[12:22:21] <Bearded_Comrade> ye, cool sounding name
[12:22:28] <Bearded_Comrade> maybe

[12:22:40] <guerillaengineer> Well, poo.
[12:23:00] <Bearded_Comrade> well, i'm trying to build a 4 legged robot now
[12:23:14] <guerillaengineer> I'm into bio-Medical Engineering myself. Cool, crab bot
[12:23:19] <guerillaengineer> *Joke*
[12:23:25] <Bearded_Comrade> cool
[12:23:45] <guerillaengineer> Not really. With tech the way it is, I'll be stuck making insulin injectors
[12:23:56] <Bearded_Comrade> do you cnc in your spare time?
[12:24:12] <Bearded_Comrade> or is it relevant to bio-eng?
[12:24:15] <guerillaengineer> Building my first unit as we speak. My hobby is mostly lasers
[12:24:19] <Bearded_Comrade> ah
[12:24:24] <Bearded_Comrade> thats a fun hobby
[12:24:42] <guerillaengineer> I'll be creating macro-scale models of veins and proteins at home.
[12:24:42] <Bearded_Comrade> are you the quantity or quality type o guy?
[12:24:54] <guerillaengineer> quality, except for my love of CO2
[12:25:15] <Bearded_Comrade> ie do you have one big lazer that burns through everything?
[12:25:55] <guerillaengineer> I make my own mirrors for folded designs, at least I used to. That's what this machine is for as well.. I can cut through people if they stand perfectly still for 14 seconds.
[12:26:09] <guerillaengineer> hopefully I'll be completing a railgun this semester
[12:26:42] <Bearded_Comrade> Do you expect me to talk? No Bond, I expect you to stand still for 14 seconds!
[12:26:51] <guerillaengineer> hahaha
[12:27:01] <XXCoder> lol
[12:27:03] <guerillaengineer> That's so true it's crazy
[12:27:25] <Bearded_Comrade> i had a cool idea that used a rail gun
[12:27:28] <Bearded_Comrade> so
[12:27:40] <Bearded_Comrade> you know how scram jets are pretty solid state
[12:28:02] <Bearded_Comrade> they basically have the compressor and the fuel goes in and ignites
[12:28:04] <guerillaengineer> Another reason for cncing is I have an idea to isolate shielding gases between mirrors only microns thick. Human in half in 2 seconds. Yeah, I'm familiar with scrams
[12:28:22] <Bearded_Comrade> so make a scramjet
[12:28:39] <Bearded_Comrade> that is small
[12:28:44] <guerillaengineer> With a big-ass transformer and a parallel cap array?
[12:28:49] <Bearded_Comrade> maybe 1 meter long
[12:28:55] <Bearded_Comrade> but scram jets only work mach 4+
[12:29:03] <Bearded_Comrade> so use the rail gun to shoot it
[12:29:17] <guerillaengineer> the force would rip your face off
[12:29:25] <Bearded_Comrade> exactly
[12:29:25] <guerillaengineer> Let me calculate really quick
[12:31:43] <guerillaengineer> Shoulder-mounted, the air would literally blow your top-half clean off. You would need a mount to support, and even then it may flip (even a hummer dug in the ground) unless it had a 300lb weight on the nozzle
[12:32:07] <Bearded_Comrade> oh yeah, this would have to be ground mounted
[12:32:19] <XXCoder> would a heavy tank work
[12:32:20] <Bearded_Comrade> cause you are launching a scramjet to 4+ mach
[12:32:34] <guerillaengineer> one sec
[12:32:42] <guerillaengineer> American modern?
[12:32:45] <Bearded_Comrade> depending on how big of a scramjet you wanna shoot
[12:33:02] <Bearded_Comrade> i mean, if the scramjet is really small, like a mini 20 cm one
[12:33:26] <guerillaengineer> I guess it could work, but a 2cm would displace, one sec
[12:33:32] <XXCoder> usa army has been researching kenetic kill weapons
[12:33:56] <guerillaengineer> My brother works on a strike squad that is developing that, it's declassified so I can finally open my fat mouth!
[12:34:06] <XXCoder> its apparently so fast that shooting though air or water makes no difference
[12:34:41] <guerillaengineer> 2cc SS one-fuel shot at 4+M would displace around 19ft of ground matter moving at 0/ms
[12:35:25] <guerillaengineer> That would hit a building, then propel the matter it hit through the rest of the building (assuming cinder black of solid 1-foot width) and land at about 40 yards away
[12:36:01] <guerillaengineer> So essentially you made a shotgun taht operates under the principle that the target is the shot!
[12:36:39] <guerillaengineer> The capacitive array would need about 200farads? I'm guesstimating. That's a BUTTLOAD of power
[12:37:20] <Bearded_Comrade> it aint worth building if its not at least a bit insane
[12:37:33] <guerillaengineer> ^ The point of what we do
[12:38:01] <guerillaengineer> Anyone familiar with the RAMPS 1.4?
[12:38:29] <Bearded_Comrade> no, i've only heard of it
[12:38:33] <XXCoder> heh im reading this silly book that has discriptation of special weapon that shoots 3 cc pellet at 0.8C
[12:38:46] <XXCoder> if you miss pellet leaves solar system evenually
[12:38:55] <Bearded_Comrade> and anything that it does hit?
[12:39:38] <XXCoder> it hits and explodes so hard. but then at that speed air would be "still" so it does not work. it would cause fusion while flying though air!
[12:39:44] <guerillaengineer> 681.3keV/c^2
[12:40:27] <XXCoder> by the way https://what-if.xkcd.com/1/
[12:40:39] <guerillaengineer> That's the relativistic momentum. It would only take around 2 years (outside of acceleration of any present atmosphere) to exit Pluto's axis
[12:41:19] <guerillaengineer> Yeah, excitation alone would destroy a bunch of junk
[12:42:09] <guerillaengineer> I've been experimenting with homopolar motors to find a feasible pulse rifle though
[12:43:01] <XXCoder> how does pulse rifle idea work
[12:43:09] <guerillaengineer> Basically plasma only stops short (which is creat for cutting metal) but if you superheated the surrounding environment it couls go as far as the heat
[12:43:22] <guerillaengineer> great*
[12:43:57] <guerillaengineer> It's like a railgun, but with EMFs
[12:44:14] <XXCoder> interesting
[12:44:55] <guerillaengineer> Have you guys heard of the new laser method to imprint like 20TB worth of data on a dvd?
[12:45:07] <XXCoder> got a link?
[12:45:51] <guerillaengineer> one second, and it's 1,000 Terabytes
[12:46:04] <guerillaengineer> http://phys.org/news/2013-06-storage-terabytes-dvd.html
[12:46:18] <guerillaengineer> I'm doing that, but with plasma in the middle of the resisting laser
[12:46:28] <XXCoder> I still remember reading about machine that can write and read from small crystal block, and it could hold 1 tb, and read speed was 1 Tb/s
[12:47:03] <guerillaengineer> The graphene reader?! Yeah, that's awesome
[12:47:16] <guerillaengineer> Allspark, right there
[12:47:32] <XXCoder> graphite? must be new one
[12:47:47] <XXCoder> One I menioned was holographic system using 2 lasers

[15:24:58] <pcw_home> Strange, pretty sure it worked out-of-the-box for me
[15:25:09] <pcw_home> (though running master)
[15:26:35] <pcw_home> realistically its probably easier to take a current config file set and change the names for Ethernet than make a whole new config
[15:30:36] <lair82> Do I need to add --enable-run-in-place to the ./configure line?
[15:32:21] <lair82> I wanted to try the wizard because of how I building a mill now instead of a turning center, and the fimware is readily available, unlike the lathes that we did.
[15:35:32] <pcw_home> pncconf will not currently make configs for the Ethernet cards
[15:36:18] <lair82> Oh, ok, won't try to go down that road then.
[15:36:43] <pcw_home> (though you can select similar PCI card firmware and make a config, and then use an editor to globally replace the card name in the file)
[15:38:13] <pcw_home> the .hal file I should say
[15:38:14] <lair82> pcw_home I have a substantial order to place, will it ship today, if ordered this morning?

[15:55:44] <lair82> I did everything from the command line, using git. I don't fully understand the buildbot, I put those lines in the software sources section, then updated, and installed. But how do you then check the dependencies, and start linuxcnc?
[15:56:14] <JT-Shop> ok, then you didn
[15:56:22] <JT-Shop> 't use the hybrid iso then
[15:57:37] <JT-Shop> I don't understand buildbot either
[15:58:23] <lair82> That's what I installed, I downloaded it from the download page, put it on a usb, and Debian is what is installed now
[15:58:32] <CaptHindsight> just FYI, I have installed Wheezy first then added all the Linuxcnc + RTAI and kernel packages as well as installed from the Linuxcnc Wheezy hybrid ISO and the results are different
[15:59:00] <JT-Shop> what did you add with git?

[16:45:40] <zeeshan> this is how the tool sits
[16:45:54] <zeeshan> i guess i have to press the drawbar button first (i dont have hydraulic power yet)
[16:45:59] <syyl_ws> yes

[16:49:41] <zeeshan> look at the cylindrical part of the tool holder though
[16:49:53] <zeeshan> what makes it look iso40
[16:50:01] <zeeshan> online it does say iso40 everywhere for the wf21c
[16:50:06] <zeeshan> but it makes no mention about pull stud
[16:50:12] <zeeshan> or retaining mechanism
[16:50:12] <syyl_ws> iso40 is just the taper

[16:50:14] <syyl_ws> nothing else

[16:50:21] <archivist> yes that is the style on my horizontal
[16:50:33] <syyl_ws> 2080 is the style of the holder which allready has a pull stud
[16:50:35] <zeeshan> archivist: with the cylindrical extension?
[16:51:08] <syyl_ws> there is also din 68971(or something like that) that has no extension, where the pull stud is screwed in
[16:51:24] <archivist> the extension is from the early use where a draw bar was used
[16:51:31] <zeeshan> "ISO describes the taper itself , DIN 2080 describes a style of clamping in the machine.'
[16:51:57] <zeeshan> so i guess it can be
[16:52:01] <zeeshan> ISO40 DIN2080
[16:52:46] <CaptHindsight> they have align the parts off camera http://www.youtube.com/watch?v=Ic3jfVwmDyQ#t=22 this is a terrible pick-n-place

[16:53:20] <archivist> may I recommend http://www.tools-n-gizmos.com/specs/Tapers.html
[16:53:28] <lair82> I am still trying to figure out how to disable the hardware graphics driver on this new FM2A88X-ITX+ MB. I see in the troubleshooting manual that this " radeon.modeset=0 " should disable it, but do I do that from the command line, or where?
[16:53:53] <CaptHindsight> lair82: kernel parameter in grub
[16:54:01] <zeeshan> so
[16:54:06] <zeeshan> this TOOL holder is the correct one for the machine!
[16:54:19] <syyl_ws> horrible amount of tapers and styles out there, archivist :D
[16:54:34] <archivist> see nmbt on that page
[16:54:48] <zeeshan> i am
[16:54:51] <archivist> that also has the 2080 in the section
[16:55:04] <syyl_ws> looks correct :)
[16:55:25] <zeeshan> so it doesnt matter what the trhread is in the end
[16:55:28] <zeeshan> cause i dont make use of it.
[16:55:42] <zeeshan> all i care about is where that groove near the cylindrical part is
[16:55:45] <zeeshan> and how wide it is
[16:55:48] <lair82> so just "sudo mousepad grub.conf", and add this line/
[16:57:07] <zeeshan> okay
[16:57:10] <zeeshan> this makes 100% sense
[16:57:14] <zeeshan> the key size i measured was .625"
[16:57:16] <zeeshan> with the mike.
[16:57:32] <zeeshan> and im looking through catalogs and they make specific nmtb 40 tool holders to make use with .625" key
[16:57:46] <syyl_ws> :)
[16:57:56] <CaptHindsight> lair82: I believe to save the kernel parameter in Wheezy so it boots with it every time edit: /etc/default/grub Then run: update-grub and reboot
[16:58:54] <zeeshan> archivist: is your machine nmtb40?
[17:00:04] <archivist> no it is an in between 35 ish which now seems to be missing from that page
[17:00:49] <archivist> my impression your holder is not from that machine
[17:01:01] <zeeshan> doesnt it look like din2080?
[17:01:09] <zeeshan> to you..
[17:01:30] <zeeshan> it looks exactly like that nmtb holder on that tools-n-grizmos site
[17:01:33] <archivist> that ebay item has a slot
[17:01:52] <archivist> SK40 is perhaps the other clue
[17:02:09] <zeeshan> if you google "mikron wf 21 din2080 iso40"
[17:02:17] <zeeshan> a whole bunch of links pop up where machines are for sale
[17:02:22] <zeeshan> so it must be it :P

[17:08:44] <zeeshan> wouldnt it be one button then?
[17:08:51] <zeeshan> which applys pressure when held
[17:09:20] <zeeshan> ill see what thsoe buttons are hooked up to :P
[17:10:21] <archivist> the idea being the holding force does not rely on constant pressure from the release mechanism
[17:10:43] <zeeshan> yes
[17:10:48] <zeeshan> its normally closed :)
[17:10:54] <zeeshan> and open when you pressure the pressure button
[17:10:57] <syyl_ws> one button gives clearance, then with the other the hydraulic is opened
[17:10:58] <zeeshan> im curious why there is 2 buttons
[17:11:20] <syyl_ws> then, when you press the button again it pulls the tool in
[17:12:11] <syyl_ws> the first one would be like a safety
[17:12:18] <syyl_ws> again, wild guess ;)
[17:12:20] <zeeshan> hehe
[17:12:25] <zeeshan> do you know if the hydraulic pump is always on
[17:12:30] <zeeshan> on these machines
[17:12:42] <zeeshan> or if it only comes on when you press the buttons
[17:12:47] <zeeshan> i still need to trace the wires
[17:12:49] <syyl_ws> not on those i ran
[17:12:51] <zeeshan> since i have no electric schematics.
[17:13:07] <zeeshan> okay then it must prolly come on
[17:13:09] <zeeshan> when you press the button
[17:13:20] <zeeshan> i also need to see if it has some sort of builtin over-pressure safety switch
[17:13:28] <syyl_ws> it will have
[17:13:32] <syyl_ws> that stopts the pump
[17:15:04] <zeeshan> i was reading some features online about other machines
[17:15:10] <zeeshan> apparently you can use the hydraulic pump
[17:15:16] <zeeshan> to provide hydraulic clamping of fixtures :P
[17:15:58] <syyl_ws> there might be three solenoid valves
[17:16:20] <syyl_ws> one for horizontal, one for vertical and maybe one for the brake on a cnc rotary axis

[17:25:10] <CaptHindsight> lair82: sorry I'm not a debian guru :)
[17:25:33] <CaptHindsight> lair82: why do you need the preempt_rt kernel vs RTAI?
[17:26:27] <lair82> I am going to be running the 7I80HD board from mesa
[17:26:59] <CaptHindsight> why doesn't the 7i80HD work with RTAI?
[17:27:47] <lair82> Apparently not,
[17:28:14] <CaptHindsight> lair82: what is your reason for wanting to disable the hardware accel driver?
[17:32:39] <CaptHindsight> we didn't look into preempt_rt much
[17:33:20] <CaptHindsight> we worked on the new RTAI branch and we had to disable kernel mode settings to have low latency
[17:34:28] <CaptHindsight> I don't know what the best settings are for kernel parameters with preempt_rt
[17:34:29] <lair82> I have noticed that the latency will run very low, 5-7k ns, but when I start dragging windows around, it shoots right up, 30,40,50k ns
[17:34:49] <pcw_home> I would not worry about latency at this point
[17:37:25] <lair82> pcw_home, ok, I guess I'm just paranoid for no reason, after all the ups and downs on the first three builds, now going off in uncharted territories has me nervous.

[18:21:03] <zeeshan> The Alpha series is our commercial 3D filament printing series. It is a large, heavy, solid machine built to handle the needs of commercial production printing, educational,
[18:21:04] <zeeshan> lol
[18:21:09] <zeeshan> large, heavy :P
[18:23:12] <CaptHindsight> made from the densest of hardwoods?
[18:24:35] <CaptHindsight> http://dev.metvnetwork.com/assets/images/bamboo%20car.jpg well it was good enough for Gilligan
[18:25:09] <PetefromTn_> HEHEHE cracks me up
[18:26:35] <PetefromTn_> designed from the ground up as a hybrid milling machine capable of high speed and stiffness needed for both milling metal and effective printing and engraving.
[18:27:08] <PetefromTn_> Outfitted with acme screws, dual 1/2 steel rails, and 200 watt 48v drive motors on all axes
[18:28:47] <syyl_ws> hey
[18:28:55] <syyl_ws> thats bullshit bingo :D
[18:29:06] <syyl_ws> the whole text
[18:29:13] <syyl_ws> and "hybrid" always sounds cool
[18:29:16] <PetefromTn_> says it is linux based wonder if it is just a reconfigured linuxCNC>
[18:29:31] <syyl_ws> kinda scifi
[18:29:35] <PetefromTn_> bullshit bingo LOL
[18:29:45] <zeeshan> bhahaha acme screws
[18:29:47] <PetefromTn_> I'm gonna have to use that one...
[18:29:47] <zeeshan> i didnt even notice that
[18:36:34] <lair82> Our $56000 Fagor retrofit on our 18x60 Cincinatti MO Lathe says "Decompressing Linux Files" when it boots up from a power outage
[18:37:18] <PetefromTn_> ooh nice got any pictures of that Cincinatti lathe?
[18:37:35] <syyl_ws> heidenhain controllers also run on linux
[18:37:39] <syyl_ws> thats not uncommon
[18:37:40] <PetefromTn_> is it a CNC turning center?
[18:37:54] <lair82> Don't believe so, I will have to get some and share
[18:38:32] <PetefromTn_> I am still trying to borrow a heavy duty trailer so I can go get my new CNC lathe retrofit project.
[18:38:52] <lair82> Yep, 1980 vintage, complete retrofit, drives servo's spindle motor controller
[18:39:17] <zeeshan> heidenhain is pretty nice
[18:39:18] <PetefromTn_> thats how ya do it in my humble opinion... all brand new if you can swing it.
[18:39:18] <lair82> What kind of lathe?
[18:39:20] <zeeshan> with their glass scales!
[18:39:47] <PetefromTn_> it's a Standard Modern

[18:41:50] <PetefromTn_> LinuxCNC is the control program for CNC machined this forum is based on
[18:41:57] <PetefromTn_> machines
[18:43:05] <Marfu_> Can I install this program on ubuntu?
[18:43:12] <PetefromTn_> yes
[18:43:16] <Marfu_> how?
[18:43:16] <PetefromTn_> that is what mine runs on
[18:43:30] <Marfu_> I search linuxcnc
[18:43:42] <PetefromTn_> best way is to download and burn the setup disk to a CD but there are quite a few ways apparently.
[18:43:43] <Marfu_> but not found apt-get not found it
[18:44:16] <Marfu_> no, i need this program in my normal computer no dedicated computer
[18:44:49] <PetefromTn_> http://www.linuxcnc.org/index.php/download
[18:45:57] <Marfu_> Your link is ISO not program
[18:46:10] <Marfu_> whole distribution not only one program
[18:46:54] <PetefromTn_> LinuxCNC is an open-source project. Currently we keep the source-code in "Git" (a versioning system) at git.linuxcnc.org. You can browse the sources online, using gitweb , or download them (instructions).
[18:47:14] <PetefromTn_> not sure what you are after but that is where they keep the source code.
[18:48:51] <Marfu_> ok
[18:48:57] <pcw_home> If you intend to actually run a machine you will need a real time kernel in addition to the linuxcnc software
[18:48:59] <Marfu_> i try to compile it
[18:49:12] <Marfu_> och
[18:49:17] <Marfu_> i undestand
[18:49:39] <Marfu_> what RTOS is in linuxcnc distribution?
[18:49:52] <pcw_home> RTAI
[18:50:15] <Marfu_> thanks
[18:50:29] <pcw_home> but master (the development version) can run under Preemt-RT alo
[18:50:36] <pcw_home> also
[18:51:12] <Marfu_> ok. I will read about it

[19:04:38] <zeeshan> me like
[19:04:43] <Connor> Do you not have that machine in a enclosure ?
[19:04:49] <ssi> sorta?
[19:04:55] <ssi> I never got around to adding the lexan ;)
[19:04:58] <Connor> and man is that video crappy
[19:05:05] <ssi> yeah fb video isn't great
[19:05:10] <zeeshan> ssi
[19:05:12] <zeeshan> for all these machines
[19:05:13] <ssi> I just didn't feel like taking the time to youtubs it
[19:05:15] <Connor> So, what are you doing about fumes ?
[19:05:16] <zeeshan> you surely have a 1970s camera
[19:05:17] <zeeshan> :D
[19:05:22] <ssi> it's not the camera
[19:05:32] <ssi> Connor: the bed has downdraft exhaust
[19:05:44] <Connor> okay. That's good
[19:05:59] <zeeshan> the silicone
[19:06:01] <zeeshan> has no chance
[19:06:02] <ssi> it'd work VERY well if the enclosure was enclosured
[19:06:06] <zeeshan> its getting raped=!
[19:06:06] <ssi> as is it works fine
[19:06:26] <zeeshan> ssi
[19:06:31] <zeeshan> how does the laser beam
[19:06:33] <zeeshan> make it into the head
[19:06:36] <zeeshan> from that huge glass tube
[19:06:39] <ssi> mirrors
[19:06:48] <Connor> Duh
[19:06:56] <zeeshan> but the head is moving
[19:07:09] <Connor> one of the mirrors is on the head.
[19:07:13] <lair82> ssi Is that using them boards I sent you/
[19:07:14] <ssi> there's three mirrors
[19:07:27] <ssi> one is fixed, one is on the left side of the gantry, and moves with Y, one is in the head and moves with X
[19:07:31] <ssi> the beam path stays rectilinear
[19:07:43] <ssi> lair82: no, it's on an optiplex... one of the boards you sent me is getting built into my VMC
[19:07:44] <zeeshan> ahh
[19:07:58] <lair82> I see
[19:08:07] <lair82> Pretty cool regardless
[19:08:07] <zeeshan> lair82: the mill with the tnc 155
[19:08:11] <zeeshan> what kind of tool holder does it use
[19:09:14] <lair82> Not sure, I would have ask the operator
[19:13:41] <ssi> zeeshan: I got that hook spanner from mcmaster, and sure enough it's armstrong
[19:13:48] <zeeshan> lol
[19:13:50] <ssi> mcmaster's prices are high, and graingers are 2x what mcmasters are
[19:14:01] <zeeshan> i dont even know who buys from grainer
[19:14:06] <ssi> me either
[19:14:08] <zeeshan> they sell a 1hp motor
[19:14:10] <zeeshan> for 800$
[19:14:11] <zeeshan> ..
[19:14:19] <ssi> best part is
[19:14:22] <ssi> I should have gotten a smaller one
[19:14:24] <ssi> the hook is too big :(
[19:14:28] <zeeshan> fak
[19:14:31] <zeeshan> grind it down :P

I will be calling monday with my order, I'm building 2 VMC controls at one time, and buying a spare of everything for the turning centers.
[19:23:13] <PetefromTn_> damn you're a busy boy er girl?
[19:23:37] <lair82> boy, :)
[19:23:43] <PetefromTn_> what MB?
[19:23:49] <ssi> that reminds me, I ordered another 7i77 kit the other day, wonder when it'll be showing up
[19:23:52] <ssi> tomorrow perhaps
[19:24:15] <PetefromTn_> I really need to get my 7i77 shipped out to PCW so he can see if it can be repaired..
[19:24:21] <lair82> Yep, a friend of ours has an identical 10vc-1000 machining center, so we are doing both machines at the same time,
[19:24:28] <ssi> PetefromTn_: what's wrong with it?
[19:24:41] <PetefromTn_> I blew it the fuck up awhile back LOL
[19:24:45] <ssi> oh you blew an output driver didn't you
[19:24:48] <ssi> like I did on my '76
[19:25:00] <PetefromTn_> no idea but the field I/O section is apparenlty down.
[19:25:05] <ssi> entirely?
[19:25:14] <PetefromTn_> PCW said I could send it back and he might be able to repair it.
[19:25:20] <PetefromTn_> Gonna be needing it for the Lathe.
[19:25:20] <ssi> so your machine is down right now?
[19:25:26] <lair82> FM2A88X-ITX+ with a AMD A6300 CPU
[19:25:26] <ssi> oh you got another one I guess
[19:25:29] <PetefromTn_> No this is the other 7i77
[19:25:35] <PetefromTn_> I have two combos here.
[19:25:38] <ssi> yea
[19:25:46] <PetefromTn_> one is still working beautiful in the machine.
[19:25:52] <PetefromTn_> ;)
[19:25:53] <ssi> :)
[19:26:05] <ssi> I think i'll have four 5i25s when the new kit comes
[19:26:07] <PetefromTn_> unless you think you can fix it LOL?
[19:26:22] <ssi> two '77s, a '76, and the one for the plasma table which uses a 7i75 and thcad, plus g540
[19:26:31] <ssi> I might be able to fix it, but you're better off sending it to him
[19:26:36] <PetefromTn_> agreed
[19:26:53] <PetefromTn_> I need to whip up a CNC router table like yours here at some point.
[19:27:02] <ssi> plus a machine on a 5i23, one on a 7i43, and a spare 7i43 on hand
[19:27:11] <ssi> yeah I want to build a router too
[19:27:16] <PetefromTn_> Just bought a brand new Air conditioning system for my house so gotta install that now probably this week,
[19:27:22] <ssi> in fact now that I have the whole hangar for machine shop
[19:27:29] <ssi> maybe I'll go whole hog and build a 4x8 router
[19:27:34] <ssi> that'd be freakin sweet
[19:27:35] <PetefromTn_> hell yeah..
[19:27:48] <PetefromTn_> I would not bother unless it was full size sheet capable.
[19:27:57] <ssi> yeah
[19:28:01] <ssi> for home, I just don't have the space
[19:28:04] <ssi> but now I have the space at the airport
[19:28:26] <ssi> maybe I'll reinvest the money from this laser job into a router :)
[19:28:37] <ssi> also I want to build a new frame with bed height control for the laser
[19:28:41] * JT-Shop just bought an exhaust bender swager expander

[19:32:50] <Connor> Are they interconnected ?
[19:32:59] <PetefromTn_> he said they are selling by the pound LOL
[19:33:00] <ssi> Connor: they're adjacent, and I can take panels down in between
[19:33:06] <ssi> PetefromTn_: yeah that's pretty common
[19:33:13] <PetefromTn_> he said many are TSC
[19:33:16] <Connor> ssi Cool
[19:33:20] <ssi> I wish I had tsc :/
[19:33:29] <PetefromTn_> mine machine has it as an option.
[19:33:34] <ssi> mine does too
[19:33:37] <ssi> but I don't have the option
[19:33:39] <PetefromTn_> I have considered trying to get it setup
[19:33:46] <ssi> and from what I've seen of the books, it doesn't look trivial to add
[19:33:47] <PetefromTn_> not sure what would be entailed
[19:34:02] <ssi> the cabling in the Z cable chain is different
[19:34:05] <PetefromTn_> the coolant lines are already up there.
[19:34:06] <ssi> different coolant trays and pump
[19:34:17] <ssi> it's a much higher pressure system I think
[19:34:17] <PetefromTn_> coolant trays?
[19:34:25] <ssi> yeah, on my machine the tray is different
[19:34:28] <PetefromTn_> yeah would have to upgrade the pump
[19:34:29] <ssi> for tsc
[19:34:51] <PetefromTn_> might need to somehow regulate the flood coolant from the TSC coolant
[19:35:00] <PetefromTn_> it makes a HUGE difference when drilling holes.
[19:35:06] <ssi> yeah
[19:35:09] <ssi> pressurized chip removal
[19:35:24] <PetefromTn_> Those carbide drilles with TSC can be fed stupid fast
[19:35:46] <PetefromTn_> we did it a lot in the shop I worked in and it is impressive to say the least.
[19:35:59] <ssi> I'm sure
[19:36:07] <ssi> I want to get a decent facemill
[19:36:13] <ssi> and chaw on some aluminomnomnoms

[19:47:21] <PetefromTn_> Well you're right JT but right now I make everything I needed to make and I wish I had work to do hehehe I am hoping to hear from a customer early in the week next week that MIGHT be promising.
[19:47:44] <PetefromTn_> Hell yeah right. Makes my shit feel turtle slow...LAZY turtle slow LOL
[19:47:46] <ssi> hm do they make ACME thread mills?
[19:48:10] <PetefromTn_> but they probably paid more for the coolant than I have in my whole machine.
[19:48:28] <ssi> they probably made more off that one job than you have in your whole machine :P
[19:48:39] <PetefromTn_> I would hope they made a lot more than that...

[19:49:18] <PetefromTn_> That is my hope tho to get some jobs like that so I can work my way up to a machine like that

[19:49:30] <PetefromTn_> Brother drill and taps are crazy fast
[19:49:41] <ssi> https://www.youtube.com/watch?v=_oHlyF0skNE
[19:49:43] <CaptHindsight> double arm ATC mechanism system reduces tool-to-tool tool changes to 0.9 seconds
[19:49:45] <PetefromTn_> but they are pretty expensive for one that capable.
[19:50:10] <PetefromTn_> most of those drill and taps don't even use arm toolchangers it is like a round turret head.
[19:50:40] <PetefromTn_> Now that is freakin' cool....
[19:50:51] <CaptHindsight> maybe belt load them like 20mm rounds in a cannon
[19:50:58] <PetefromTn_> I need some of those inserts when I get my lathe CNC

[20:00:25] <zeeshan> ssi
[20:00:30] <zeeshan> i was thinking at some point hooking up a live spindle
[20:00:32] <zeeshan> in the QCTP
[20:00:37] <PetefromTn_> checkout 6:51 thats is really cool
[20:00:43] <zeeshan> and somehow using PID to eliminate slip
[20:00:46] <zeeshan> and using the vfd to index..
[20:00:48] <ssi> the broaching?
[20:00:51] <PetefromTn_> yeah
[20:01:00] <PetefromTn_> that bitch can do it all...
[20:01:06] <ssi> zeeshan: that's what we have to figure out for spindle orientation on our vmcs
[20:01:17] <ssi> it's fine for orient, might not be so great for livetooling
[20:01:22] <ssi> cause you really need to hold it rigidly in position
[20:01:25] <zeeshan> yes
[20:01:27] <zeeshan> so you'd hook up a brake
[20:01:28] <ssi> and induction motors won't do that well
[20:01:31] <ssi> yeah you'd need a brake
[20:01:36] <zeeshan> i was thinking mechanical brake

[20:13:53] <CaptHindsight> so fast you don't even see them
[20:15:13] <PetefromTn_> I have heard and seen that in person in Guantanamo Bay Cuba when we were there for refresher training when I was stationed aboard the USCGC Steadfast years ago and let me tell you even from hundreds of yards away it is quite impressive....
[20:15:38] <PetefromTn_> sounds like a very loud machine more than a gun really...
[20:20:36] <ssi> I gotta figure out how I'm going to count these parts
[20:20:44] <ssi> thought about doing it by weight but I don't think that's gonna work
[20:21:07] <zeeshan> why
[20:21:16] <ssi> because I didn't strip the chad out of all of them
[20:21:21] <ssi> so they'll weigh heavier than they actually are
[20:21:36] <zeeshan> lets say you have a 1000
[20:21:53] <zeeshan> you think all that crap will end up weighing more than one part? :P
[20:21:58] <ssi> yes
[20:22:13] <zeeshan> shoulda kept a counter!
[20:22:16] <zeeshan> when you were machining :P
[20:22:39] <ssi> I did
[20:22:42] <ssi> but I didn't have 100% yield
[20:22:48] <zeeshan> o
[20:23:51] <ssi> eh maybe I'll do it by weight anyway, and just estimate the amount of overage due to chad and err in their favor

[20:28:01] <ssi> and yeah there really are that many :(
[20:28:05] <ssi> 25,000 is a lot of damn parts

[20:30:02] <ssi> thanks a pantload
[20:30:04] <ssi> :D
[20:31:10] <ssi> I could seriously make a delta arm that mounts overhead of the laser, and when the cycle is done, the gantry retracts out of the way and the arm would pick and stack all the parts into boxes
[20:32:41] <PetefromTn_> you could buy that little pick and place machine they had up in that dealers shop LOL
[20:32:50] <ssi> I want that thing
[20:32:53] <ssi> but it'd be too small for this :)
[20:33:02] <ssi> I honestly considered riding back up there and trying to grab it
[20:33:05] <PetefromTn_> I know you do hehe
[20:33:36] <PetefromTn_> well if you can get a trailer I will drive up with you and we can get em both...
[20:33:47] <ssi> I don't have access to a trailer big enough for your lathe
[20:33:56] <PetefromTn_> any car trailer would work.
[20:33:57] <ssi> but the little picknplace would go on my utility trailer ok
[20:34:19] <ssi> my car won't pull a trailer big enough for your lathe :)
[20:34:26] <ssi> I mean it probably will
[20:34:31] <ssi> but some safety nazi will give me shit about it
[20:34:39] <PetefromTn_> NO we will take the bronco..
[20:34:55] <ssi> sounds expensive ;)
[20:35:04] <PetefromTn_> you drive up here, we rent a trailer and split the cost and drive up there and getem
[20:35:18] <PetefromTn_> I figured it would be like $150.00 in fuel both ways.

[20:37:36] <ssi> seriously though, its 398 miles from my house to louisville, 800 miles / 50mpg is 16 gal * 3.50/gal is $56 in fuel round trip
[20:37:40] <ssi> :D
[20:39:53] <PetefromTn_> not towing that machine and trailer it's not LOL
[20:40:01] <ssi> eh it'll be 46 prolly
[20:40:20] <ssi> I bet I could average over 50 pulling the trailer if I Was willing to go 62mph or less the whole way
[20:40:39] <ssi> I got 59mpg average over 800 miles at 62mph once
[20:40:46] <PetefromTn_> well the offer stands I need to get that machine here somehow so I will be going that way anyways...
[20:40:47] <ssi> and the diesel really doesn't care about the load
[20:41:01] <ssi> are you doing it tomorrow?
[20:41:11] <PetefromTn_> possibly..

[20:41:35] <PetefromTn_> dunno if he will open on Sunday...
[20:41:53] <PetefromTn_> he agreed to meet me even on the weekend to load it if I gave him enough notice tho..
[20:41:54] <ssi> I promised podponics I'd get these 5000 parts cut this weekend
[20:42:07] <ssi> how much is it to rent a trailer?
[20:42:23] <PetefromTn_> not sure probably like $75.00 or so.
[20:42:28] <ssi> that's not terribl
[20:42:35] <PetefromTn_> At least I rented a UHAUL car trailer awhile back for that much.

[21:13:34] <ssi> they slide
[21:13:35] <zeeshan> it slides over the next guys hanger?
[21:13:35] <ssi> overlap
[21:13:36] <zeeshan> lol
[21:13:40] <ssi> yeah
[21:13:43] <zeeshan> that would make me mad!

[21:15:46] <Connor> Get the hanger on the back side.. and remove the panels.
[21:16:14] <ssi> Connor: I would love to have B1 or B2 instead of A3
[21:16:16] <ssi> but it's not in the cards :/
[21:16:45] <ssi> SpeedEvil: holy crap
[21:16:49] <Connor> Don't think you could convince B1 or B2 to swap ?
[21:16:54] <ssi> no
[21:16:57] <ssi> B1 definitely not
[21:16:59] <ssi> I dunno who's in B2
[21:17:06] <Connor> By not B1 ?
[21:17:09] <Connor> Ass hole ?
[21:17:10] <ssi> it's a delta pilot
[21:17:15] <ssi> they're all self absorbed pricks
[21:17:18] <ssi> and he has a ton of crap in there
[21:18:56] <PetefromTn_> what a jerk, guy has hangars with lots of crap in them LOL
[21:19:12] <ssi> he's not a jerk for having crap in his hangar
[21:19:18] <ssi> he's just a jerk :)
[21:19:31] <PetefromTn_> hehe
[21:22:07] <PetefromTn_> Whats a good chinese dish OTHER than Shrimp with Lobster Sauce, Kung Pao, General Tso and lo mein? Trying to decide on order and wanna try something new LOL

[21:25:07] <zeeshan> wow
[21:25:18] <zeeshan> so a guy wanted my number on ebay seeing my pl 110b ad
[21:25:22] <zeeshan> he calls me, he's like
[21:25:33] <zeeshan> he'll give me $100 for the cable that goes from the pl to the heidenhain controller
[21:25:33] <zeeshan> lol
[21:25:40] <zeeshan> he's been looking for it everywhere and they dont make a replacement
[21:25:57] <zeeshan> damn old controls
[21:25:59] <ssi> dang
[21:26:06] <ssi> yeah that's why I had no interest in trying to run my old control as is
[21:26:15] <ssi> I wish I'd get some movement on my control parts :/
[21:26:17] <zeeshan> i'm glad you pushed me to get the amc drives..
[21:26:24] <ssi> yeah man, screw running old drives
[21:26:35] <ssi> (he says, while still running the Hiak drives in his hnc)
[21:27:17] <PetefromTn_> no chinese recommends?

[21:40:10] <ssi> there's really weird noises coming from my neighbors across the streuet
[21:40:18] <ssi> it sounds like they have a puma trapped in a garbage can
[21:40:28] <PetefromTn_> fighting cats?
[21:40:37] <ssi> I only hear one
[21:40:42] <ssi> and it's making a lot of ruckus like it's in something
[21:40:43] <_DannyK_> Have you ever heard a puma in a garbage can?
[21:41:00] <PetefromTn_> my neighborhood has several stray cats and they sometimes get into it and it sounds pretty amazingly violent for not much damage hehe

[21:41:15] <ssi> _DannyK_: what's it to you?!
[21:41:26] postaL_offline is now known as postaL
[21:41:57] <PetefromTn_> you would probably need a pretty big garbage can and some brave bastard to try to put it in there LOL
[21:42:01] <ssi> heehhe
[21:42:37] <_DannyK_> ssi: I'm just wondering the kinds of experience you had... I would be interested in that one.... :P
[21:42:49] <ssi> if I have, I'm taking it to the grave ;)
[21:43:08] <_DannyK_> oh, that isn't fair!
[21:43:33] <ssi> anyone around that knows a little about hall commutation?
[21:44:03] <_DannyK_> Like a hall sensor?
[21:44:31] <ssi> like a hall sensor, but with lots of other important things happening with the motors and the spinning
[21:45:08] <_DannyK_> oh, a quadrature hall effect sensor on a motor?
[21:45:10] <PetefromTn_> well looks like it's gonna be General Tso's Chicken, Shrimp fried Rice and Sweet and Sour Chicken with a side of Crab Rangoon and Egg rolls YUMM!
[21:45:24] <ssi> in the ballpark, but they're not quadrature
[21:45:37] <ssi> they're 120 degree sensors that overlap with six states
[21:45:47] <_DannyK_> oh those, I hate those
[21:46:03] <PetefromTn_> Freakin' Fanuc ;)
[21:46:04] <_DannyK_> Fist industrial machine I've ever worked on had those
[21:46:08] <ssi> the parker gemini manuals has a procedure for determining the correctness of hallstates by applying voltage to phases in a particular order
[21:46:19] <_DannyK_> First*
[21:46:20] <ssi> but its instructions are given in THALL state number, which is particular to those drives
[21:46:38] <ssi> and I'm trying to figure out how to correlate their THALL states to the actual lines
[21:46:45] <ssi> so I can verify my commutation pattern
[21:47:24] -!- jasen has quit [Quit: Page closed]
[21:47:52] <_DannyK_> I've done little work as to see if the sensor is working correctly, other then change the 2 sensors and see if it work now
[21:48:10] <ssi> ooh maybe the chart in their manual will help me
[21:48:58] <ssi> looks like THALL 1 should be AbC
[21:51:09] <ssi> then Abc, ABc, aBc, aBC, abC, AbC
[21:51:49] <_DannyK_> Hopefully, this isn't related to your production run you started last night...
[21:52:05] <ssi> haha no
[21:52:16] <ssi> this is me working on my VMC retrofit while the laser runs :)
[21:53:04] <_DannyK_> good...
[21:53:30] <ssi> the laser is little steppers

[22:00:12] <ssi> 14 shots in an automatic? what kind of crap is that
[22:00:13] <PetefromTn_> I have seen a few guys convert paint ball guns into pellet rifles and they are actually pretty cool..

[22:15:58] <zeeshan> druckschalter - pressure switch
[22:16:21] <zeeshan> HMM
[22:16:48] <zeeshan> getting close in figuring out this hydraulic mystery
[22:17:54] <MrHindsight> but in China it's difficult to find a restaurant that delivers :)
[22:18:20] <ssi> lo
[22:18:26] <ssi> in soviet china, restaurant deliver you!
[22:18:36] <MrHindsight> heh
[22:18:58] <PetefromTn_> https://www.youtube.com/watch?v=UjLO_CrZRmM What about this guy?

[22:21:14] <zeeshan> his hydraulic accumulator complies with the requirements of druckbehalterverordnung . The prescribed druckprufung revealed no client complaints
[22:21:17] <zeeshan> i got that so far
[22:21:33] <MrHindsight> zeeshan: https://www.swisschalet.com/ haven't seen those before
[22:22:47] <zeeshan> i guess druck means pressure :)
[22:23:01] <zeeshan> gionna eat ill be back :D

[22:49:51] <SpeedEvil> a linux PC?

[22:50:07] <SpeedEvil> Can't you just export the display?

[23:04:06] <SpeedEvil> or just straight X
[23:04:19] <zeeshan> okay guys
[23:04:34] <zeeshan> theres 3 main electrical components on the hydraulic power pack
[23:04:41] <zeeshan> electric motor, pressure switch, and solenoid valve
[23:04:57] <zeeshan> is the pressure switch supposed to trip a contactor which kills power to the pump?
[23:05:18] <zeeshan> similar to an air compressor
[23:05:44] <SpeedEvil> seems likely
[23:06:05] <zeeshan> i find that a bit weird
[23:06:13] <zeeshan> like why would they not have some sort of internal relief valve
[23:06:15] <SpeedEvil> Or if the switch is properly rated - it may simply be put in series with the motor
[23:06:18] <SpeedEvil> It depends
[23:06:18] <zeeshan> when it overpressurizes?
[23:06:22] <SpeedEvil> it might do
[23:06:32] <zeeshan> or are they trying to stop the pump from unnecessarily working
[23:06:39] <SpeedEvil> possibly
[23:06:41] <zeeshan> it does have an accumulator
[23:06:46] <zeeshan> so it stores some of that pressurized fluid..
[23:06:50] <ssi> probably has a popoff valve but it's not designed to be used to normally regulate the pressure
[23:07:52] <zeeshan> SpeedEvil: if it was rated to handle the motor currents
[23:07:55] <zeeshan> i think it'd be already in series
[23:08:00] <zeeshan> from what i can tell
[23:08:02] <SpeedEvil> likely
[23:08:06] <zeeshan> the old wires went to a contactor
[23:08:34] <zeeshan> im assuming this..
[23:08:41] <zeeshan> that you pass +24VDC through the pressure switch
[23:08:56] <zeeshan> which is likely normally closed
[23:09:05] <zeeshan> and asap the pressure switch hits some value, the switch opens
[23:09:10] <zeeshan> and trips the contactor
[23:09:24] <zeeshan> ill check with an ohmmeter to see if its normally closed
[23:09:43] <zeeshan> i wish this thing had some sort of gauge on it to show pressure.
[23:11:36] <SpeedEvil> no reason not to add one
[23:11:55] <zeeshan> it might not be too easy
[23:11:59] <zeeshan> unless there is already a port on the valve block
[23:12:27] <SpeedEvil> ah
[23:12:48] <zeeshan> maybe T it in between the accumualtor
[23:12:51] <zeeshan> and the valve body
[23:12:51] <zeeshan> hmm
[23:12:54] <zeeshan> http://i.imgur.com/dd2OCGU.jpg
[23:13:00] <zeeshan> where that orange bottle meets the valve
[23:13:20] <zeeshan> i can see why this thing is surrounded by 1/8" plate
[23:13:24] <zeeshan> just incase it blows up!
[23:13:24] <zeeshan> haha
[23:13:58] <zeeshan> jeez that solenoid valve is $427!!
[23:13:59] <zeeshan> haha
[23:19:47] <CaptHindsight> zeeshan: is that a hydraulic pump?
[23:20:14] <zeeshan> yes
[23:20:35] <CaptHindsight> I didn't notice that your mill used hydraulics
[23:20:48] <zeeshan> :/
[23:20:56] <CaptHindsight> for the ATC, chuck?
