[00:45:01] <somenewguy> makes me sad this computer won't boot
[00:45:12] <somenewguy> I like that the fan outputs actually have a spec on how much power they can source
[00:45:31] <somenewguy> four million jumpers tho, no wonder the manual is 140 pages long
[00:45:52] -!- amiri_ has quit [Read error: Connection reset by peer]
[00:47:59] <somenewguy> now since I am just running a mini mill, it occurs to me there is PLENTY of room in this case to stuff my 24 volt supply and gecko drivers
[00:48:06] <somenewguy> think that would be too noisy, or work just fine?
[00:48:22] -!- jaketea has quit [Ping timeout: 240 seconds]
[00:48:24] <somenewguy> It looks like I'll need to buy a new mobo and processor tho
[00:49:49] <Tom_itx> if things are shielded and grounded properly it should work fine

[01:01:15] <XXCoder> somenewguy: just \get egg holder foam sheet
[01:01:32] <XXCoder> stick it on side safely away from computer stuff

[01:12:08] <somenewguy> I meant electrical noise
[01:12:37] <somenewguy> its a work shop, anything quiter than a 2 stage comperssor in the next room is fine
[01:15:19] <XXCoder> oh yeah
[01:15:27] <XXCoder> sounds like something faraday cage would help
[01:16:53] <XXCoder> googling it up eh

[01:17:14] <CaptHindsight> somenewguy: I put stepper and servo drives into the same case as the PC all the time
[01:17:39] <CaptHindsight> you have to be sure you have enough airflow/cooling
[01:18:08] <CaptHindsight> but power and electrical noise has never been a problem for me
[01:19:04] <CaptHindsight> but people tend to have more problems by running 13ft of USB and VGA cable out to their monitor and keyboard :)

[01:20:46] <zeeshan|2> :D
[01:21:01] <zeeshan|2> i call that the mill corner!

[01:22:38] <Tom_itx> git rid of that car in the way and you'd have alot more room
[01:22:51] <XXCoder> indeed
[01:23:03] <zeeshan|2> i think im more into racing than machining
[01:23:05] <zeeshan|2> so that'll enver happen
[01:23:09] <XXCoder> or turn it into transformer that turns from car into massive cnc machine
[01:23:15] <zeeshan|2> haha XXCoder ilike that idea!
[01:23:17] <XXCoder> and back
[01:23:28] <zeeshan|2> turns into a massive laser cutter
[01:23:34] <XXCoder> just dont press that button while racing ;)
[01:23:41] <zeeshan|2> i can be a sore loser
[01:23:53] <zeeshan|2> and machine other cars while we're race preping
[01:23:56] <zeeshan|2> and then transform
[01:24:13] <XXCoder> heh. so you making parts for yourself?
[01:24:21] <XXCoder> for rce car
[01:24:26] <zeeshan|2> XXCoder: yes i do that a lot
[01:24:29] <G0704> I'm after 3 hours of griding with my dremel.
[01:24:31] <zeeshan|2> thats how i started
[01:26:03] <zeeshan|2> has anyone used a siemens sub panel?
[01:26:06] <G0704> I've make the room for the X axis ball nut.
[01:28:32] <G0704> what cuplers to buy?

[01:34:00] <G0704> I need it?
[01:34:21] <XXCoder> lovejoy coupling :P
[01:35:37] <somenewguy> CaptHindsight: thanks, I will put chokes on all long cables, if only cause I can get em from the trash at work
[01:35:49] <Tom_itx> G0704, you may want a more direct connection
[01:36:02] <Tom_itx> too much backlash with that coupler
[01:36:39] <somenewguy> I'm looking at moving into a new place w/ a 2 car garage and a basment with a real cieling, and sice my car doesn't fit in the garage, there is only one way this can end...
[01:38:38] <somenewguy> also are intel atom's still the best bang for the buck for a mill pc, or has a new favorite been found? I thought someone said they were ending em
[01:38:57] <XXCoder> raspberry pi heh
[01:38:58] <somenewguy> looking at newegg right now, thinking if I throw out all my old pcs I can "reward" myself with new parts!
[01:39:02] <somenewguy> hush you
[01:39:15] <somenewguy> I have two of those and already know you're messing w me
[01:40:29] <XXCoder> heh I do want to get one, but just unsure what I would do with one.
[01:40:35] <somenewguy> car computer?
[01:40:43] <somenewguy> thats' what mine are for
[01:40:46] <XXCoder> theres project that uses it and nook simple touch into fun
[01:42:43] <somenewguy> argh parametric search won't work on newegg for me
[01:42:49] <somenewguy> clearly a sign I need to go work on my car
[01:42:54] <somenewguy> would be nice to have somethign to drive to work in tomorow...
[01:43:06] <XXCoder> meh just walk there ;)
[01:45:07] <somenewguy> 9 miles in teh snow? this aint 1942
[01:45:18] <Tom_itx> uphill both ways?
[01:45:29] <somenewguy> not since '35
[01:45:38] <somenewguy> according to gramps
[01:47:14] <malcom2073> Tom_itx: With no feet?
[01:47:35] <XXCoder> the uphill both ways is from gravity warping. it went away, but it should come back when you're 80s and complaining to kids.
[01:49:40] <XXCoder> okay the joke didnt work :P

[02:21:10] <bobo_> zeeshan|two Looks as if you are on the final stage of wiring the mill
[02:21:26] <CaptHindsight> does anyone keep the Linuxcnc machine on their network?
[02:21:37] <CaptHindsight> and internet connected?

[02:43:39] <skunkworks> (it is at the shop - sometimes dad leaves it on...)
[02:45:04] <bobo_> blame it on good old Dad
[02:47:40] <skunkworks> well - the main breaker is off - so you couldn't just turn it on...

[02:51:55] <G0704> someone here know cemistry?
[02:52:47] <skunkworks> bobo_: thank you. it has been making a lot of parts.
[02:54:34] <G0704> I've did today etching with salt water
[02:54:45] <G0704> and it's work very good
[02:55:10] <G0704> but i want to learn the camistry of it.

[03:13:19] <G0704> I've make an electrolosis, the solotion is salt water, the negative is iron, and the positive is copper. the iron (negative) start to make yellow color, and the copper stay without change. the iron also lose material. so something eat the iron
[03:13:20] <zeeshan|2> cube i got it i got it!
[03:13:20] <zeeshan|2> :D
[03:13:25] <G0704> the yellow can be FeCl3 ? Iron(III) chloride?

[03:14:05] <zeeshan|2> moose mill corner
[03:14:27] <[cube]> looks great :)
[03:14:35] <zeeshan|2> its heavy as hell man
[03:14:43] <zeeshan|2> not as heavy as the bridgeport clone was
[03:14:44] <zeeshan|2> but still
[03:14:56] <zeeshan|2> im not digging that 2 bolt clamp mechanism
[03:14:58] <zeeshan|2> to stop it from rotating
[03:14:59] <zeeshan|2> lol
[03:15:06] <zeeshan|2> (the head)
[03:15:09] <[cube]> heh
[03:15:15] <[cube]> try it out for a while
[03:15:20] <[cube]> see if you notice any movement
[03:15:23] <[cube]> do some tests
[03:15:27] <[cube]> i havne't got that far yet
[03:15:30] <zeeshan|2> im sure it will be fine man
[03:15:38] <zeeshan|2> i plan to onyl do light manual milling on it
[03:15:44] <[cube]> http://imgur.com/a/uaYbT
[03:16:02] <zeeshan|2> that turned out nice man
[03:16:08] <[cube]> i tested it, works pretty well
[03:16:14] <[cube]> doing some leak testing right now
[03:16:16] <zeeshan|2> i love the look of that print
[03:16:19] <[cube]> not that leakes really matter...
[03:16:38] <zeeshan|2> is that a threaded port for the oil inlet?
[03:16:51] <[cube]> nope
[03:16:57] <[cube]> just pressure fit
[03:17:01] <[cube]> its very snug
[03:17:08] <[cube]> .3 mm smaller than hose
[03:17:11] <zeeshan|2> ah
[03:17:13] <[cube]> and its 2 cm deep
[03:17:15] <zeeshan|2> you can always loctite it too
[03:17:34] <[cube]> oh the screw?
[03:17:43] <[cube]> its just to hold on that once side piece
[03:17:45] <zeeshan|2> http://i.imgur.com/yWNEhQo.jpg
[03:17:47] <zeeshan|2> right side port
[03:17:48] <[cube]> to clamp on to the brass
[03:18:01] <[cube]> ah
[03:18:02] <[cube]> yea
[03:18:03] <[cube]> just pressure
[03:18:14] <zeeshan|2> total print time? :p
[03:18:25] <[cube]> heh about 10 hrs
[03:18:29] <zeeshan|2> jeez lol
[03:18:36] <[cube]> for both parts
[03:18:46] -!- swingley has quit [Remote host closed the connection]
[03:18:47] <[cube]> about 4-5 each
[03:18:54] <[cube]> running it very slow
[03:18:58] <[cube]> becasue of the overhangs
[03:19:44] <zeeshan|2> if you go too fast, the plastic layer doesnt bond?
[03:20:03] <zeeshan|2> i am using a sla ? type 3d printer at school this semester
[03:20:06] <zeeshan|2> just got my TA assignment
[03:20:16] <[cube]> ah nice
[03:20:17] <zeeshan|2> gotta laser cut and 3d print parts for 2nd year projects
[03:20:23] <[cube]> yeah if you go too fast lots of nasty things happen
[03:20:26] <[cube]> you get rough edges
[03:20:32] <[cube]> stringy pieces during travel
[03:20:48] <[cube]> hah score
[03:20:49] <[cube]> ur all set
[03:20:55] <zeeshan|2> if ________________ < is table from the side
[03:20:59] <zeeshan|2> can you print a part like this:
[03:21:03] <zeeshan|2> |______|
[03:21:09] <zeeshan|2> or does it have to be \_________/
[03:21:11] <os1r1s> [cube]: Is that nylon or PLA?
[03:21:11] <[cube]> yes
[03:21:12] <zeeshan|2> slightly tapered
[03:21:18] <[cube]> vertical is preferred
[03:21:31] <[cube]> tapered is just for building steps to an overhand and/or decorative
[03:21:35] <[cube]> pla
[03:22:00] <os1r1s> [cube]: Nice design, but you should be able to print quicker. Thats a pretty small part
[03:22:01] <[cube]> one weird thing i'm noticing with the pla, and not sure if its just the infill % or the material or what
[03:22:12] <[cube]> but its almost like the oil is 'permeating' the part
[03:22:29] <zeeshan|2> sweats
[03:22:30] <zeeshan|2> hm
[03:22:30] <[cube]> yeah i could have probably done it in half the time easily
[03:22:37] <[cube]> but i didnt want to risk haveing to reprint
[03:22:42] <[cube]> im still workign out kinks
[03:22:45] <zeeshan|2> sounds like its porous :P
[03:22:49] <[cube]> and wanted these parts to get mill going
[03:23:02] <zeeshan|2> you have the bug
[03:23:08] <zeeshan|2> gotta mod the mill before even starting it!
[03:23:09] <zeeshan|2> :P
[03:23:23] <os1r1s> [cube]: I think you'd be better off printing that in Nylon. My .02
[03:23:30] <[cube]> agreed
[03:23:44] <zeeshan|2> why os1r1s
[03:23:51] <[cube]> i've never printed with nylon, will have to pick some up
[03:23:52] <os1r1s> zeeshan|2: Nylon is stronger than PLA
[03:23:58] <[cube]> i have abs here i could try
[03:24:08] <zeeshan|2> any other advantage?
[03:24:09] <os1r1s> Don't use loctite near ABS
[03:24:24] <zeeshan|2> why it melts? :P
[03:24:26] <[cube]> these parts wont be under any particular stress
[03:24:30] <os1r1s> zeeshan|2: I think it would be more chemically resistant. But not sure.
[03:25:01] <zeeshan|2> "Polylactic Acid is a biodegradable, grease and oil resistant, high clarity material"
[03:25:04] <os1r1s> Since PLA is biodegradable, I'm guessing that oil will eventually eat it away
[03:25:20] <[cube]> yeah, we'll find out soon enough :)
[03:25:28] <os1r1s> loctite causes ABS to crack
[03:25:32] <[cube]> luckily its easily removed/replaced
[03:25:54] <[cube]> 'oil resistant'....doesn't give me the warm fuzzies :P

[03:27:23] <[cube]> also need to consider how my coolant and other oils/lubes like wd40 will affect the parts
[03:27:28] <[cube]> they'll no doubt be exposed
[03:27:47] <zeeshan|2> well nylon i know is pretty damn good
[03:27:50] <zeeshan|2> i use it for fuel lines
[03:27:52] <[cube]> should just spray a bunch of crap on the parts and let sit for a couple days
[03:28:17] <[cube]> yeah nylon sounds like a good idea
[03:28:23] * [cube] gets out credit card...
[03:28:27] <zeeshan|2> http://www.jegs.com/images/photos/555110920.jpg
[03:28:28] <zeeshan|2> that stuff
[03:29:09] <zeeshan|2> doh
[03:29:12] <zeeshan|2> thats nitrile inner tube
[03:29:13] <zeeshan|2> nm.
[03:29:32] <furrywolf> I use rubber for fuel lines. heh.

[03:29:42] <zeeshan|2> that stuff is nylon
[03:29:48] <zeeshan|2> furrywolf: why
[03:29:59] <furrywolf> ford, however, does use nylon fuel lines... they like cracking.

[03:34:51] <[cube]> or Nylon 618
[03:34:52] <os1r1s> [cube]: I use nylon 618. 645 should be much better
[03:35:01] <os1r1s> If doing it again I would get 645
[03:35:07] <[cube]> ah okay

[03:38:36] <bobo_> I am talking about size vers max chuck dia vers small dia parts
[03:40:16] <bobo_> rpm wise
[03:40:24] <furrywolf> that lathe isn't meant for very small parts, period. :P
[03:41:23] <bobo_> give him some numberrs Mr furry
[03:42:16] * furrywolf has no numbers
[03:43:17] * furrywolf contemplates making a prisoneresque joke, but fails
[03:43:57] <bobo_> also rpm of spindle bearings expensive spindle bearings did I mention expesive low rpm bearings
[03:45:31] <zeeshan|2> bobo_: prolly a good thing i am not getting it :P
[03:49:52] <furrywolf> couldn't work out transportation?
[03:50:00] <zeeshan|2> nahh
[03:50:03] <zeeshan|2> no space
[03:50:07] <zeeshan|2> see the pic abov ei posted :P
[03:50:30] <bobo_> I am not wishing you don't get the lathe , just wondering your thinking of chuck Dia vers max rpm vers rpm used for smaller dia stuff
[03:50:47] <zeeshan|2> bobo_: i know it was a low speed lathe
[03:50:55] <zeeshan|2> i work on a lot of stainless and steel
[03:51:54] <zeeshan|2> theyre like 800 rpm lathes
[03:52:01] <zeeshan|2> but people bump em up to 1200
[03:54:00] <furrywolf> what pic?
[03:54:18] <bobo_> those old timken taper bearings might get very hot around 900 rpm
[03:54:22] <zeeshan|2> grr i posted it 2 times already!! :P
[03:54:23] <furrywolf> I see fuel hose and fittings.

[03:54:37] <furrywolf> did you perhaps post it before I joined the channel? :P
[03:54:46] <zeeshan|2> oh i did
[03:54:47] <zeeshan|2> sorry :P
[03:55:14] <furrywolf> that's much, much more space than I have.
[03:55:20] <zeeshan|2> not enough for that lathe
[03:55:28] <furrywolf> I have a tiny house with no garage or storage, and a rental storage unit I have to drive to.
[03:55:39] <zeeshan|2> a lot of my stuff is in the basement
[03:55:50] <zeeshan|2> so its not enough space!
[03:56:06] <furrywolf> and no basement here either.
[03:57:45] <bobo_> zeeshamm blow out the formal dineing room wall
[03:58:38] <zeeshan|2> haha

[03:59:55] <zeeshan|2> how to find pinouts for this motor
[03:59:59] <zeeshan|2> need to find out which lead is+
[04:00:16] <zeeshan|2> if it spins clockwise
[04:00:45] <zeeshan|2> and my +v wire is connected to a specific pin,
[04:00:48] <zeeshan|2> is that a + pin? :P
[04:01:36] <furrywolf> does flickr not have any form of embiggening function anymore?
[04:01:57] <bobo_> use 9volt batt. seek and ye shall find
[04:02:08] <furrywolf> clicking on the image, like every single other site on the planet, instead goes to the next image.
[04:02:32] <zeeshan|2> furrywolf: yea its a terrible service
[04:02:38] <zeeshan|2> im looking to get my own hosting in the future
[04:03:46] <Tom_itx> just put up a home server
[04:03:56] <zeeshan|2> too slow tom
[04:03:56] <furrywolf> does it matter? hook them up whichever way rotates the way you need to it? it should be reversible...
[04:04:12] <zeeshan|2> furrywolf: i wanna follow the + and - in the servo drive manual
[04:04:18] <zeeshan|2> so when i hook up the tachometer, there are no suprises
[04:04:33] <zeeshan|2> and im being anal about guessing the wires because the servo drives are retarded mechanically
[04:04:40] <zeeshan|2> remember the screws? theyre not accessible for the motor leads
[04:04:46] <zeeshan|2> so i'd have to dismount the 5 drives ..
[04:04:54] <furrywolf> if it runs away, swap the wires? :P
[04:05:05] <zeeshan|2> i dont wanna do it twice
[04:05:12] <zeeshan|2> cause its a bish to swap wires
[04:05:39] <Tom_itx> do one and see
[04:05:44] <Tom_itx> then do the rest
[04:06:06] <furrywolf> swap the wires on the motor end where it's easier?
[04:06:28] <zeeshan|2> Tom_itx: lets say ive hooked up a moto r a certain way, and i hooked up a tacho a certain way.. and i notice a run away condition.. how do i know whether the motor leads are reversed or the tacho is reversed
[04:06:48] <zeeshan|2> i think thats the longest sentence i've written since ive been in here
[04:07:10] <Tom_itx> i'm not sure, i don't have servos
[04:07:15] <zeeshan|2> hehe
[04:07:21] <Tom_itx> i would think ou could reverse one or the other
[04:07:22] <furrywolf> are the inputs to your drive labeled "clockwise" or similar?
[04:07:24] <Tom_itx> and be ok
[04:07:26] <furrywolf> otherwise, it doesn't matter.
[04:07:34] <zeeshan|2> furrywolf: no just + and -
[04:08:02] <zeeshan|2> okay so if my motor leads are reversed, and tacho is as required by the manual, and i end up flipping the tacho wires
[04:08:12] <furrywolf> so decide what you want them to mean. do you want a + step to be clockwise? or to move the axis in the positive direction? or to not care and just set the software to whatever works?
[04:08:14] <zeeshan|2> that means everytime i command a + position in linuxcnc, it will try to go the opposite way
[04:08:18] <zeeshan|2> and i've have to invert the signal?
[04:08:25] <zeeshan|2> that bothers me for some reason
[04:08:36] <Tom_itx> i inverted one of my drives
[04:08:43] <bobo_> 9volt batt on motor meter on tack
[04:08:44] <zeeshan|2> i dunno in engineering positive rotation is counter clockwise
[04:08:46] <furrywolf> if you don't want to invert any signals, then hook it up whichever way makes a + step move the positive axis direction.
[04:09:04] <furrywolf> bobo: I doubt a 9v battery will make his motor rotate.
[04:09:20] <Tom_itx> just change the sign of the SCALE
[04:09:22] <zeeshan|2> i have a 12v car battery
[04:09:30] <Tom_itx> in the ini
[04:09:40] <furrywolf> then if you do it that way, since some of your leadscrews probably run the opposite direction, you'll need to set them in software anyway.
[04:10:07] <zeeshan|2> fair enough
[04:10:09] <furrywolf> bobo: his motor is 137V, >2kW. a 9V battery tops out at, what, 1W, for short periods? :P
[04:10:19] <zeeshan|2> so i'll hook up my motor leads any random way
[04:10:30] <zeeshan|2> and if the motor runs away, ill flip the tachometer wires
[04:10:38] <zeeshan|2> cause thats a lot easier to do
[04:10:40] <Tom_itx> organized random
[04:10:52] <zeeshan|2> im just a bit afraid of a run away. never experienced it
[04:10:52] <furrywolf> it'd be a very efficient motor if it runs at .05% of its rated power!
[04:10:54] <zeeshan|2> sounds very violent
[04:11:01] <bobo_> car batt use light bulb in series to limit the Oh Shit
[04:11:23] <zeeshan|2> these are 2 hp servos
[04:11:30] <zeeshan|2> they can prolly do some damage
[04:11:36] <Tom_itx> my X axis SCALE is negative, my Y axis SCALE is positive
[04:11:40] <zeeshan|2> im hoping you clamping them down with a big ass c-clamp will be ok
[04:11:44] <furrywolf> zeeshan: don't have it connected to the machine during initial testing.
[04:11:50] <zeeshan|2> furry it wont be
[04:11:53] <zeeshan|2> but the motor will jump
[04:11:58] <zeeshan|2> ive had dinky little mtors jump on me
[04:12:02] <zeeshan|2> i cant imagine how violent this will be..
[04:12:08] <zeeshan|2> by dinky i mean rc car motors
[04:12:10] <furrywolf> a runaway on a servo motor is fine... a runaway on an axis may result in needing parts.
[04:12:12] <Tom_itx> when you power it, give it a very low feedrate
[04:12:28] <furrywolf> tom: if it runs away, it won't care what the feedrate is.
[04:12:31] <Tom_itx> and if it takes off you know something is backwards
[04:12:33] <zeeshan|2> i have a "test mode"
[04:12:39] <Tom_itx> i know that furrywolf
[04:12:41] <zeeshan|2> when it's in test mode and the motor leads are connected..
[04:12:49] <zeeshan|2> you can rotate the motor by using a pot
[04:12:53] <furrywolf> zeeshan: rathet strap it down to something.
[04:12:56] <zeeshan|2> maybe i can figure out the direction based o nthat?
[04:13:01] <Tom_itx> but if it creeps along you know that one is right
[04:13:12] <zeeshan|2> yea pcw was mentioning that before
[04:13:15] <zeeshan|2> if its drifting ill know
[04:13:23] <zeeshan|2> but if its run away, ill definitely know!
[04:13:27] <zeeshan|2> (scared me)
[04:15:04] <zeeshan|2> will found out tomorrow
[04:15:06] <bobo_> try 9 volt batt (good 9volt batt) just to tell me i am wrong servo no load
[04:15:15] <zeeshan|2> bobo_: i tried 24vdc psu before
[04:15:18] <zeeshan|2> they spun
[04:15:30] <zeeshan|2> i dunno if 9v will do it
[04:16:17] <zeeshan|2> i believe the coil resistance is 12 ohms
[04:16:25] <zeeshan|2> i dont remember
[04:16:47] <bobo_> will turn enough to find direction vers polarity
[04:17:03] <zeeshan|2> its a bit sad
[04:17:07] <zeeshan|2> but i dont have a9v battery :P
[04:17:11] <zeeshan|2> only 12v
[04:17:26] <furrywolf> a 12v non-tiny battery is much more likely to make it spin.
[04:17:55] <furrywolf> 9v batteries are only good for a couple hundred ma tops, and they'll melt if you do that for more than a couple seconds...
[04:17:58] <zeeshan|2> the z motor will be a bit annoying to figure out
[04:18:00] <zeeshan|2> cause it has a brake
[04:19:01] <Tom_itx> block the spindle up with wood
[04:19:20] <bobo_> if car batery I would use light bulb in series for less oh shit the lead fell off
[04:20:12] <zeeshan|2> im gonna just experience that a run away is all about
[04:21:53] <Tom_itx> the wood will keep it from damaging the table
[04:22:22] <zeeshan|2> Tom_itx: my spindle moves in the y direction
[04:22:23] <zeeshan|2> :)
[04:22:28] <Tom_itx> ahh
[04:22:30] <zeeshan|2> my table already fell down
[04:22:34] <Tom_itx> heh
[04:22:35] <zeeshan|2> when i disconnected the servo
[04:22:37] <zeeshan|2> :-(
[04:22:45] <zeeshan|2> it wasn't too dramatic though
[04:22:49] <zeeshan|2> i tried to stop it, but failed
[04:23:07] <zeeshan|2> i think that is an important note for hobbyists..
[04:23:10] <bobo_> for zeeshans mill the Z axis is table goes up and down it's a german thing
[04:23:13] <zeeshan|2> do not disconnect the Z without support
[04:23:20] <zeeshan|2> you can get your finger stuck in between the belt and the motor.
[04:23:25] <zeeshan|2> and likely chop it off
[04:23:33] <Tom_itx> anybody for that matter
[04:25:04] <zeeshan|2> servos are a bit scary..
[04:25:52] <zeeshan|2> a failure of servo tachometer
[04:25:58] <zeeshan|2> is enough to cause a run away from my understanding
[04:26:03] <furrywolf> yes
[04:26:20] <zeeshan|2> shoulda gone with steppers :P
[04:26:43] <furrywolf> steppers suck for large or fast things
[04:26:55] <zeeshan|2> another situation i can think of
[04:27:11] <zeeshan|2> is if linuxcnc doesn't know you're in e-stop mode and and the power to the servo drives is killed
[04:27:25] <zeeshan|2> so the position loop is still running
[04:27:38] <zeeshan|2> and you get out of e-stop mode
[04:27:44] <zeeshan|2> you can have a huge run away
[04:27:48] <zeeshan|2> am i right??
[04:27:57] <t12_> shouldn't all this be handled by tracking error e-stop maximums
[04:28:12] <furrywolf> I think linuxcnc will abort with a following error if the encoder stops matching what it tells it to do.
[04:28:23] <CaptHindsight> just start out slow with limited current
[04:28:28] <bobo_> oh no! zeeshan will you stop with the stepper thing
[04:28:33] <zeeshan|2> bobo_: im kidding haha
[04:28:35] <CaptHindsight> I use linear servos all the time
[04:28:55] <zeeshan|2> CaptHindsight: i already have them set to the absolute lowest current setting
[04:29:04] <zeeshan|2> so the run away wont be too aggressive?
[04:29:25] <t12_> i have some thing on a big iko linear servo
[04:29:28] <t12_> that thing is sorta scary
[04:29:39] <t12_> i think it may be able to propel itself off a table if not bolted down
[04:29:44] <zeeshan|2> haha
[04:29:50] <furrywolf> I haven't yet found anything with servos within my budget.
[04:29:50] <zeeshan|2> rail gun
[04:29:53] <CaptHindsight> I bump them back and forth first to see which way they are going if it's some new setup
[04:31:39] <CaptHindsight> linear servos also generally come with big springs at each end of their travel :)
[04:33:18] <t12_> this thing does not
[04:33:51] <t12_> http://www.ikont.co.jp/eg/product/mecha/mch10.html
[04:33:54] <t12_> some variant of these
[04:34:21] <CaptHindsight> those look nice
[04:34:22] <furrywolf> if I had a random linear servo lying around, there's probably one thing I'd mount on it first...

[05:34:05] <zeeshan|2> itd be a sofa in the garage basically :D
[05:34:14] <t12_> lol
[05:34:21] <t12_> kids these days, warns professor
[05:34:27] <XXCoder> actually I would grab mecury sable 1980s back chair
[05:34:39] <XXCoder> its the confortablest seat I ever sat on
[05:34:40] <zeeshan|2> XXCoder: sounds like youve had experience back there?
[05:34:42] <zeeshan|2> :-0
[05:34:44] <XXCoder> front seats is even better
[05:34:48] <bobo_> use robet arm with a plow seat
[05:35:03] <XXCoder> dude I used to own mecury sable for 9 years. its the best confort I ever hd
[05:35:12] <XXCoder> I rarely sit in back lol
[05:35:29] <XXCoder> but im always happy to sit back because damn confortable
[05:36:18] <bobo_> plow seat's have holes for running cather tube thru
[05:37:23] <zeeshan|2> you didnt get my reference
[05:37:31] <zeeshan|2> what do people do on back seats
[05:37:32] <zeeshan|2> get it?!
[05:37:39] <XXCoder> I know, I just ignored that lol
[05:37:41] <zeeshan|2> haha
[05:37:52] <zeeshan|2> are they leather
[05:37:56] <XXCoder> nah
[05:38:03] <XXCoder> I hate leather chairs
[05:38:08] <zeeshan|2> i love em!
[05:40:21] <XXCoder> cool I guess
[05:40:26] <XXCoder> ironically I love leather coat

[07:12:12] <Bushman> i have a g-code for a part but i'd like to make it multiple times one next to the other...
[07:13:26] <Bushman> any tips on which gcodes to use to make the machine mill one part after the other without me manually offseting it each time?
[07:14:05] <Bushman> it's nice and dandy when i'm doing 2 or 3... but i'll like to make a set of 10 for example

[07:25:21] <Jymmm> toastyde1th: CONTROL PANEL http://www.ironcowprod.com/wp-content/uploads/2011/12/frankensteins_laboratory.jpg
[07:25:44] <toastyde1th> AH AH AH
[07:28:37] <Bushman> toastyde1th: linuxcnc
[07:29:13] <toastyde1th> i don't have a solution for you for linuxcnc but i know for a fact there are really simple ways to do it on linuxcnc
[07:29:24] <Bushman> Jymmm: hehe :D
[07:29:26] <toastyde1th> stick around and ask periodically and you'll get a good solution
[07:30:00] <Jymmm> gcode nesting, interesting
[07:30:41] <Jymmm> Bushman: gimme an example of a part, and what the raw material is?
[07:31:39] <Jymmm> and rough dimensions of the material
[07:32:03] <Bushman> example part: polygon with few polyline openings in it. nothing fancy
[07:32:16] <Bushman> let's say a square with 3 holes in it
[07:32:16] <Jymmm> flat, like washer
[07:32:21] <Jymmm> ?
[07:32:23] <Bushman> yes
[07:32:32] <Bushman> material acrylic sheet 3mm thick
[07:32:34] <Jymmm> or gasket?
[07:32:51] <Jymmm> 3mm is what in inches?
[07:32:55] <Bushman> yea, like a gasket
[07:32:58] <Jymmm> 1/8"?
[07:33:05] <Bushman> close
[07:33:08] <Jymmm> k
[07:33:19] <Bushman> ~3.17 is 1/8"
[07:33:25] <Jymmm> close enough
[07:33:35] <Jymmm> prt dims?
[07:33:47] <Jymmm> part dimensions (max)?
[07:33:51] <Bushman> 20x30mm aproximitly
[07:33:56] <Jymmm> k
[07:34:04] <Jymmm> material dims (max) ?
[07:34:33] <Bushman> the problem is the code is in absolute coordinates system... if it was in relative i'd just nest it with a simple sub
[07:34:37] -!- mhaberler has quit [Quit: mhaberler]
[07:34:55] <Bushman> and even write the multiplying routine by hand...
[07:35:36] <Bushman> but since it isn't i'm wondering if there's something like g54 that i could use dynamically from within the program but still start wher my g54 is set by me
[07:35:38] <Jymmm> Then why don't you rewrite it in relative terms?
[07:35:59] <Jymmm> ah, you are trying to workaround the clusterfuck basically?
[07:36:07] <Bushman> yes
[07:36:09] <toastyde1th> Bushman, how i'd do it
[07:36:30] <Jymmm> Bushman: What if, you just lie to lcnc?
[07:36:35] <toastyde1th> is the controls I'm used to allow me to temporarily offset the work coords
[07:36:43] <Bushman> the thing is ther's a lot of curves on the parts... and i'll be getting more of those, not just this one code
[07:37:06] <Bushman> Jymmm: i'd love to do that... but what do you mean exactly?
[07:37:10] <Bushman> :P
[07:37:16] <Jymmm> Bushman: Just ie to her, tell her she's pretty =)
[07:37:33] <Bushman> oh, i'm telling it to her everyday ;]
[07:37:39] <Bushman> and i don't have to lie!
[07:37:40] <Jymmm> Bushman: bastard! lol
[07:37:45] <Jymmm> Awwwwwwwwwwww

[07:38:09] <Bushman> isn't she gorgeous?!
[07:38:12] <Bushman> :D
[07:38:15] <toastyde1th> jymm - i recall linuxcnc using either g92 or g10 or some such?
[07:38:17] <toastyde1th> to set coords?
[07:38:32] <Jymmm> Bushman: If the raw material is 100x100, tell it it's 300x300 or whatever
[07:39:09] <Bushman> um... i don't think i follow?

[07:39:45] <Bushman> the materiall is arbitrary... (depends on how much acrylic i hack off)
[07:39:46] <Jymmm> Bushman: you are offsetting the material to compensate for the absilutele coordin
[07:39:56] <Bushman> yes
[07:40:13] <Bushman> to put the workpiece at 0,0,0
[07:40:30] <Bushman> cause that's what the gcode thinks it is
[07:40:48] <Jymmm> right
[07:40:57] <Bushman> but i want to do that once for all 10 itterations
[07:41:11] <Jymmm> but if the material is (virtually) 300x300 instead of 100x100, what happens?
[07:41:37] <Bushman> and then just, i don't know... set a grid value like: "put another part 35mm to the right and repeat"
[07:42:01] <Bushman> i'm not sure what you mean, i don't set any material
[07:42:19] <Jymmm> where is 0,0,0 on your machine?
[07:42:29] <Jymmm> absolute
[07:43:14] <Jymmm> in the pic you linked to, where is 0,0,0 ?
[07:43:16] <Bushman> it's my arbitrary decision to put it on left front bottom corner but it used to be in different places
[07:43:31] <Jymmm> bus well, make up your mind damnit =)
[07:43:49] * Jymmm slaps the arbitraryness out of Bushman!
[07:43:55] <Bushman> i don't have home switches... it's where i put it that day
[07:43:58] <Bushman> :D
[07:44:05] <Jymmm> then I cant help you
[07:44:11] <Bushman> why?
[07:44:37] <Jymmm> if you have code that is absolute, you need machine coordinates that are absolute too
[07:44:50] <Jymmm> not arbitrary for the day
[07:45:02] <Bushman> let's assume i will install the home switches and home the machine at left bottom front corner
[07:45:19] <Bushman> it's alway + vales
[07:45:24] <Jymmm> bottom left of photo?
[07:45:25] <Bushman> values
[07:45:29] <Bushman> yes
[07:46:08] <Jymmm> ok, so slap a 100x100 piece of acrtyic on there and mark 0,0,0 with a red dot
[07:46:15] <Jymmm> got it?
[07:46:25] <Bushman> ok
[07:46:30] <Jymmm> now...
[07:46:42] <Jymmm> tel the machine it's 400x400

[07:49:06] <Bushman> yes, g90
[07:49:36] <Jymmm> I'm saying tell the machine that the absolute (vurutal) 0,0,0 is now at -4,-4,-4

[08:00:17] <Bushman> it uses g91. my code is in g90. that's the problem
[08:00:48] <Bushman> if it was output by the preprocesor in g91 i would have NO problem making it multiple times
[08:01:23] <Bushman> i would just write a simple loop that executes the code, then moves away predefined value and repeats the whole proces given number of times
[08:02:02] <Bushman> i'm looking for a way to go around it when i have a piece of code that i can't manually re-write in g91
[08:04:50] <Bushman> and this particular preprocesor does not give the option to output in g91 if you wonder
[08:11:20] <Bushman> ok, i think i might be getting somewhere...

[14:18:51] <archivist> http://www.suttontools.co.uk/hand-tools/lozenge-gravers.html but that does not show the tip grind
[14:20:28] <archivist> unfortunately hand engraving tools are also called gravers but the grind is a bit different
[14:21:36] <archivist> a favourite shape for me is the oval http://contenti.com/oval-gravers
[14:22:26] <jdh> does it want to dig in and fling the tool into your face?
[14:23:42] <archivist> you have the rest reasonably close to the work and have the tool pointing up at about 30 deg or whatever till it sounds and turns right
[14:25:17] <archivist> so it pushes the tool off rather than dig in, you have to apply some pressure
[14:30:19] <CaptHindsight> https://www.youtube.com/watch?v=PlZDg0rpIi8 my first thought was to grind it

[17:06:54] <malcom2073> 3d printing is a world of "first", most of which has been around for years
[17:07:01] <CaptHindsight> it's not the first
[17:07:04] <malcom2073> I see "first" at least once a day when looking through thigns.
[17:07:10] <malcom2073> things*
[17:07:28] <malcom2073> Saw someone using a sharpie on a plotter to make circuits, then UV etching
[17:07:42] <CaptHindsight> that one is really low res
[17:08:03] <malcom2073> There was a 3d printer that squirted out solder, that was nifty
[17:08:13] <CaptHindsight> http://jordanbunker.com/archives/41 Project: Conductive Ink
[17:08:25] <CaptHindsight> we use inkjet
[17:08:30] <CaptHindsight> have been for years
[17:08:41] <cradek> multilayer circuit boards are certainly not 2d as they state
[17:09:36] <malcom2073> CaptHindsight: Nice
[17:09:48] <jdh> hype aside, it is still interesting to me. I started CNC'ing to make PCB's
[17:10:43] <jdh> does anyone use somethign other than solder to connect components to boards? conductive glues or something?
[17:11:08] <CaptHindsight> yes, inks, pastes, ultrasonic welding etc
[17:12:21] <CaptHindsight> that Harvard project looks like another reprap offshoot

[17:25:56] <malcom2073> 30 seconds per part
[17:26:00] <malcom2073> is one million parts per year

[17:27:00] <tjtr33> CaptHindsight, I see some 'blown powder laser deposition" where metal particles are blown into airstream around laser.
[17:27:01] <tjtr33> familiar? how does the process know when enuf material has accumulated, when to move on?
[17:27:16] <malcom2073> Yep, 24/7
[17:27:26] <CaptHindsight> tjtr33: like a laser printer

[17:27:41] <malcom2073> Pretty cool looking
[17:27:42] <CaptHindsight> we do that with power coatings as well
[17:28:13] <CaptHindsight> with metal powder it's pretty predictable
[17:28:18] <tjtr33> so it assumes it's done, open loop? rates left up to operator?
[17:28:18] <CaptHindsight> the rate of build

[17:31:41] <malcom2073> Of course

[17:31:52] <tjtr33> patent = "my nozzle has a hole in it"

[17:32:51] <malcom2073> I don't know if that sort of thing will ever be home-shop level anyway, but it's a cool idea
[17:33:01] <CaptHindsight> oh yeah it can be

[17:33:42] <tjtr33> hand held laser and sand box of carbide dust
[17:33:55] <CaptHindsight> as the parts made in China drive the prices down you'll be able to DIY them

[17:37:16] <tjtr33> uv is used to cure resin, right? can a form be in the resin bath, and the laser trace over the form? thinking medical prosthesis
[17:37:31] <jdh> like inkjet ink
[17:37:47] <CaptHindsight> yeah, UV or visible
[17:38:12] <CaptHindsight> a projector can cure an entire layer in <1 second

[17:39:47] <CaptHindsight> I'm placing metal inserts into photopolymer printers
[17:40:12] <_methods> ahhh so keycaps are a 2 shot mold
[17:40:25] <_methods> i got a buddy askin me to make key cap molds for him
[17:41:15] <CaptHindsight> you can DMLS the metal, then SLA resin over that and inkjet on that as well
[17:41:52] <tjtr33> can SLA work over, say organic stuff? an orange slice?
[17:42:12] <CaptHindsight> sure

[17:43:04] <tjtr33> nice molds then, from real parts ( plaster casters return )
[17:43:15] <CaptHindsight> the reason you don't see these types of printers here is that the 3d printer co's don't share

[18:04:16] <FinboySlick> zeeshan|2: It's probably the inkjet type then.

[18:08:58] <zeeshan|2> *three
[18:09:12] <CaptHindsight> zeeshan|2: if it uses powder it's either SLS, (laser sinter) or inkjet with binder
[18:09:25] <zeeshan|2> 7.5A @ 190V, then some random I_o 6.4A , and I_o_max 7.0A
[18:09:29] <CaptHindsight> inkjet with binder gets you 4 color process
[18:09:57] <zeeshan|2> and 13.6A@173V, I_o 13.8A, I_o_max 15.3A
[18:10:05] <zeeshan|2> CaptHindsight: ah okay
[18:10:12] <CaptHindsight> it's a fancy HP45 thermal inkjet printer

[20:49:53] <zeeshan|2> more so than regular cable
[20:50:23] <alex____w> my gut feeling is that 12awg is small
[20:50:39] <alex____w> but my gut these days is around sizing dc cables, not ac cables
[20:50:43] <alex____w> so it's likely poorly tuned
[20:54:00] <zeeshan|2> i just measured fthe wires in the cable that came wit hthe machine

[20:57:22] <zeeshan|2> that table isn't derated though
[20:57:39] <zeeshan|2> for example if you look at 90C thhn.. (typical house wiring)

[22:36:28] <Jymmm> Connor: You could reverse feed it thru the existing hot wire lines
[22:36:35] <Jymmm> hot water lines *
[22:37:00] <Jymmm> Connor: Does the existing hot water heater no good?
[22:37:13] <Jymmm> or just poor
[22:37:23] <Connor> It heats, but, it's very very luke warm.
[22:37:33] <Jymmm> Ah, small tank.
[22:37:38] <Connor> 6 gallon.
[22:37:49] <Jymmm> Connor: Is there room to plumb in a spikot?
[22:38:14] <Connor> Not sure. I have access to the water lines on the inside under the stove.
[22:38:34] <Jymmm> Connor: but can you feed hot water into an exterior panel?
[22:39:01] <Connor> We have fresh water hookup if that's what your asking.
[22:39:12] <Jymmm> No I mean the hot water side
[22:39:16] <Connor> No.
[22:39:22] <Connor> Just cold only.
[22:39:31] <Jymmm> OH... does the existing hot water heater have a drain valve?
[22:39:51] <Connor> Umm.. I think it does.
[22:40:02] <Jymmm> There ya go, reverse feed it thru that
[22:40:10] <Connor> Let me go look at that.
[22:40:11] <Connor> brb
[22:40:27] <Jymmm> you might have to shut off the cold water supply to the HWH though
[22:42:22] <Jymmm> Connor: As a quick test, you can use plastic garden fittings if you have them. But if you don't already have them. Spend the money on brass fittings, it will be WELL WORTH IT. Don't ask me how I know this ;)
[22:44:38] <JT-Shop> if you have hot water why do you need to heat it
[22:44:56] <Jymmm> JT-Shop: only has a 6gal tank
[22:45:27] <JT-Shop> what does size have to do with the equation?

[22:45:58] <Jymmm> JT-Shop: In a RV, the tank size related to water temp
[22:46:28] <Tom_itx> stop taking 20 min showers!
[22:46:34] <Jymmm> JT-Shop: they are very ineffiant
[22:46:48] <JT-Shop> but the water is hot, why heat it?
[22:46:53] <Jymmm> Tom_itx: HA you could NEVER take a 20m shower... EVER
[22:47:05] <MC500> My computer died and I bought a new one with an ISA slot now EMC does not work at all... I am using EMC 2.3 for my ISA STG card, what version should I upgrade to before diving into why it doesent work?
[22:47:08] <Jymmm> JT-Shop: IT's luke water from their existing HWH
[22:47:35] <JT-Shop> so it's not a hot water heater, but a cold water heater
[22:47:57] <Jymmm> Connor: Crap, that hsoe is online only. But look for HOT WATER rubber hoses, they last forever
[22:48:21] <Tom_itx> hose from a cement truck
[22:48:27] <Tom_itx> those are pretty rugged
[22:48:43] <Jymmm> Yeah, I have two cement trucks right here, let me grab a hse
[22:48:46] <Tom_itx> i had some like that made when i did my basement
[22:48:48] <Jymmm> hose
[22:48:57] <Tom_itx> local rubber supply had it

[22:49:28] <Jymmm> he wants hot water, not $400 hose =)
[22:49:43] <Tom_itx> it wasn't $400
[22:49:53] <JT-Shop> w;hy not $400
[22:50:04] <Tom_itx> and how bad _does_ he want it?
[22:51:21] <JT-Shop> I'd say a hot shower in 10F is worth $400
[22:52:29] <JT-Shop> heating hot water seems like a waste of energy to me
[22:53:58] <Tom_itx> cold showers take much less time anyway
[22:54:34] <Jymmm> JT-Shop: You know, your HWH is now going to go out on you for saying that
[22:55:12] <jthornton> my water heater only heats cold water
[22:55:32] <_methods> hahahha
[22:55:37] <Jymmm> Well, it's gonna heat NOTHING 20 minutes before you want it to
[22:55:52] <Connor> what about running hot water line from the HOUSE ? My hotwater heater is in the shop which has a flap I can run hose out.
[22:56:27] <Jymmm> Connor: Sure, just drain it for sediment before connecting it to the RV

[22:57:45] <Connor> No. I would use the upper one.
[22:57:47] <Jymmm> Connor: DO NOT TOUCH the safety release valve though.
[22:58:49] <Connor> I have a connect for the clothes washer in that room.. direct off the hot.
[22:59:09] <Connor> clothes washer no longer in the shop.. it in 2nd bathroom in house now.. :)
[22:59:17] <Jymmm> Connor: Fine, just use a 50ft HOT WATER HOSE
[22:59:30] <Connor> ok. wonder how much of a temp drop I'll get...
