Back
[00:01:49] <JT-Shop> I just mounted the button box
[00:01:59] <JT-Shop> starting to clean up the mess...
[00:02:00] <s1dev> looking at these small mills what's the difference between a #3 Morse Taper and an R8 taper?
[00:02:29] <Tom_itx> oh #3 is pretty weak
[00:02:33] <JT-Shop> morse is usually for drills like a tail stock on a lathe
[00:02:35] <Tom_itx> R8 has a drawbar

[00:02:50] -!- logger[mah] has quit [Remote host closed the connection]
[00:02:53] <JT-Shop> R8 is the typical bridgeport and clone type of collet

[00:02:57] -!- logger[mah] has quit [Remote host closed the connection]
[00:02:59] <Tom_itx> #3 won't hold much side force
[00:03:02] <Tom_itx> for milling
[00:03:04] -!- logger[mah] [logger[mah]!~loggermah@ns1.mah.priv.at] has joined #linuxcnc
[00:03:05] <s1dev> so R* is ideal?
[00:03:07] <s1dev> *8
[00:03:14] <Tom_itx> common
[00:03:21] -!- Nick001-Shop has quit [Ping timeout: 244 seconds]
[00:03:37] <Tom_itx> we used 40 and 50 taper
[00:04:06] <Tom_itx> so somewhere inbetween is good
[00:06:58] <s1dev> http://www.ebay.com/itm/TREE-10-1-2-x-42-VARIABLE-SPEED-VERTICAL-MILLING-MACHINE-2UVR-/160883320556?pt=LH_DefaultDomain_0&hash=item257564a6ec
[00:07:03] <s1dev> too bad it's in the wrong state
[00:08:15] <s1dev> and the wrong voltage as well
[00:10:34] <Tom_itx> does mesa make a small standalone vfd card?
[00:10:45] -!- Nick001 [Nick001!~Nick001@clsm-74-47-85-39-pppoe.dsl.clsm.epix.net] has joined #linuxcnc
[00:10:45] -!- micges has quit [Quit: Leaving]
[00:12:33] <Tom_itx> most of those are likely gonna be 3 phase
[00:16:04] <djdelorie> why is 3-phase a problem?
[00:16:41] <Tom_itx> generally not run to residential addresses
[00:16:52] <Tom_itx> some cnc don't like phase inverters
[00:17:12] <djdelorie> even digital ones? I mean, my bldc motors are all three-phase...
[00:17:32] <Tom_itx> it's all generated though
[00:17:37] <Tom_itx> not from the supply
[00:18:16] <djdelorie> well yeah, but it's functionally the same as provided three-phase (and maybe cleaner ;) if done right
[00:20:07] <toastydeath> digital phase converters are okay for most machines
[00:20:17] * djdelorie wonders if my bldc drivers could drive my bridgeport...
[00:20:24] <toastydeath> 2% error is generally considered good enough for a cnc
[00:20:35] <toastydeath> in voltage between phases
[00:20:40] <djdelorie> 10% error is considered good enough for home power delivery...
[00:20:54] <toastydeath> there's only one phase
[00:21:03] <djdelorie> (good thing too :)
[00:21:21] <toastydeath> machines are a little more tolerant of total voltage error but not much
[00:21:24] <toastydeath> 5-6%
[00:21:56] <Tom_itx> we had the power company put a monitor on the feed for a couple weeks when the new shop was built
[00:22:01] <toastydeath> ^^ this
[00:22:13] <toastydeath> machine installers will do the same thing if you buy from a dealer
[00:28:17] -!- broofa has quit [Ping timeout: 252 seconds]
[00:32:35] <JT-Shop> how can the voltage be wrong when you can pick between all three?
[00:33:37] <JT-Shop> s1dev: for a spindle motor 3hp and less you just get a VFD that is single phase in 3 phase out
[00:33:55] <JT-Shop> I use a GS2 as LinuxCNC has a driver for it
[00:34:08] <Tom_itx> jt does mesa have vfd's for small motors?
[00:34:22] <JT-Shop> I've not seen any
[00:34:22] <Tom_itx> i was thinking about my sherline spindle
[00:34:30] <JT-Shop> Automation Direct does
[00:34:34] <Tom_itx> someone said i could replace the pot with something
[00:34:39] <JT-Shop> is your sherline 3 phase?
[00:34:42] <Tom_itx> no
[00:34:47] <Tom_itx> dc motor
[00:34:51] <Tom_itx> 90v? maybe
[00:34:54] <Tom_itx> i dunno
[00:34:56] <JT-Shop> line voltage pot?
[00:35:02] <Tom_itx> no
[00:35:07] <Tom_itx> i don't think so
[00:35:13] <Tom_itx> i haven't torn into it yet

[00:36:10] * JT-Shop looks at the mess around the BP and ponders cleaning up
[00:36:28] * djdelorie must be donig something right, as he just got a GS2 also...
[00:37:03] <L33TG33KG34R> tjb1: you were asking if someone here was slisgrinder?
[00:37:07] <tjb1> yes

[00:37:33] <tjb1> Thats you
[00:37:38] <L33TG33KG34R> yeah, just wondering
[00:38:02] <tjb1> Whats your problem with the 220v
[00:38:22] <L33TG33KG34R> well I need to use a VFD and it needs 220V
[00:38:59] <tjb1> yes
[00:39:12] <L33TG33KG34R> so I am pondering whether or not I should route a 12-3 wire from the panel or if I should use 2 existing plugs that are on either side of the 220V center tapped and gang my breaker
[00:39:33] <djdelorie> never use two separate plugs
[00:39:54] <L33TG33KG34R> why do you say that?
[00:40:01] <jdh> Tom_itx: http://www.cnc4pc.com/Store/osc/product_info.php?cPath=25&products_id=303
[00:40:08] <djdelorie> unplugging one doesn't make the machine safe to fiddle with
[00:40:32] <tronwizard> and can make the plug out dangerous
[00:40:34] <L33TG33KG34R> yes, I would need to unplug both
[00:40:44] <djdelorie> and if you plug one of of the two plugs in the "wrong" way or place, bad things might happen
[00:40:50] <JT-Shop> djdelorie: got the GS2 up and going?
[00:41:08] <djdelorie> not yet. Just got the BP delivered last week, the GS2 is still on the counter
[00:41:27] <djdelorie> http://www.delorie.com/photos/bridgeport/
[00:41:38] <L33TG33KG34R> well, its really simple, take the hots of the 2 plugs and the ground and done. You have 220V with ground to connect to the VFD
[00:41:43] <JT-Shop> IIRC if you don't set the communication protocall they won't talk
[00:41:49] <Tom_itx> jdh, is the voltage divider in the manual speed control 0-10v?
[00:42:01] <djdelorie> first step is to just get a fixed speed working, the mill isn't CNC
[00:42:06] <jdh> Tom: dunno about yours, but most of them are.
[00:42:07] <Tom_itx> i haven't even taken it apart yet
[00:42:10] <tjb1> Im pretty sure you cant just take 2 hots and get 220
[00:42:18] <JT-Shop> was it that clean when you got it?
[00:42:23] <tjb1> You need to get the opposite hot wires off the transformer
[00:42:31] <tjb1> Otherwise youll just have 120v
[00:42:45] <djdelorie> yes, the only thing I've done with it so far is reassemble it
[00:43:01] <L33TG33KG34R> I know, I made sure the plugs are on the opposite side of the center tap from the breaker panel
[00:43:14] <JT-Shop> djdelorie: you can set it for 60 cycles and jsut use the manual speed changer
[00:43:19] <djdelorie> L33T: also, worry about ground loops, faults, etc. Please just run a new 12-3 to a dedicated outlet
[00:43:37] <L33TG33KG34R> that is what I will end up doing. Not my house to begin with
[00:43:54] <djdelorie> JT-Shop: that was the plan. The GS2 will eventually be shared with the lathe, once it has a 3-phase motor, to give it reversibility too.
[00:44:34] <ReadError> hey anyone here done a will-call order with mcmaster?
[00:44:37] <JT-Shop> ah it is a step pulley model
[00:44:43] <djdelorie> The BP is a potential CNC target, if I get to that point the GS2 will get to show its full functionality...
[00:44:46] <ReadError> ssi ?
[00:45:03] <jdh> Read: I have a friend in atlanta that does it, just goes and picks it up.
[00:45:17] <jdh> but, he also gets same-day UPS delivery if he orders early
[00:45:39] <ReadError> jdh
[00:45:42] <ReadError> i placed an order
[00:45:49] <ReadError> was just wondering if they send you an email
[00:45:53] <ReadError> like ohai its ready to be picked up
[00:45:56] <JT-Shop> djdelorie: nice clean BP
[00:45:57] <ReadError> or you just show up
[00:45:59] <jdh> oh, never asked.
[00:46:09] <djdelorie> I'd say "thanks" but it wasn't my doing ;-)
[00:46:12] <ReadError> i should throw in some endmills and stuff
[00:46:17] <ReadError> g10 kills them
[00:46:19] <ReadError> (fast)
[00:46:24] <JT-Shop> good score then
[00:46:33] <djdelorie> It was a one-owner machine, he took good care of it. Lots of oil throughout, too :-)
[00:46:48] <JT-Shop> lucky score then
[00:46:58] <JT-Shop> say goodnight Gracie
[00:46:58] <djdelorie> and it was nearby, although it still took four hours and heavy equipment to move it to my shop
[00:47:15] * JT-Shop heads inside for the night
[00:47:20] <JT-Shop> see you guys later
[00:47:58] <ReadError> how much was shipping djdelorie?

[00:50:26] <djdelorie> $425 to move it 10 miles or so, from his garage to my basement (the excavator guy again). Well worth it. it was a beast to lift and manage, and my basement is not a walk-in.

[00:53:41] -!- sumpfralle has quit [Ping timeout: 248 seconds]
[00:54:08] <s1dev> djdelorie: what all was involved in moving it?
[00:54:16] <s1dev> how do you get it on the truck?
[00:54:33] <djdelorie> it had to be pulled out of they other guy's garage into the open, and he had a dirt driveway.
[00:54:51] <djdelorie> it had to be lifted onto a trailer, and it exceeded the strength of the excavator so it was done in two parts.
[00:54:52] <s1dev> how was that managed?
[00:55:17] <djdelorie> er, rollers, boards to slide on, and an expert touch with an excavator
[00:55:33] <Bigun913> Sorry to interrupt Can anyone here help me with tool touchoff
[00:55:34] <s1dev> and how was it moved into the basement?
[00:55:46] <djdelorie> then the two parts were lowered into my bulkhead, and shifted out of the way with an engine hoist
[00:56:03] <djdelorie> like this: http://www.delorie.com/photos/southbend-lathe/img_2418.html
[00:56:25] <djdelorie> (that stairwell is removable as a module, the excavator set it aside on the lawn)
[00:56:31] <jdh> Bigun: ask the question, someone might answer
[00:58:30] <Bigun913> I dont understand how to set up tool touchoff. I am new to linux. I have the machine running and cutting but would love to be able to do auto z setting. Can anyone point me to any resources or help?
[00:59:26] <Tom_itx> http://www.gnipsel.com/linuxcnc/g-code/gen05.html
[00:59:29] <Tom_itx> yes

[01:09:22] <Bigun913> I am using a router

[01:11:16] <Tom_itx> yup
[01:11:17] <jdh> that doesn't do auto setting.

[01:12:18] <Bigun913> I came from mach 3 and like linuxcnc much more but could never get the linits or toolsetting to work
[01:12:36] <djdelorie> limits are easy to do, but not as obvious to understand

[01:35:33] <L33TG33KG34R> if I just want to control 4 steppers, a hitachi x200 or some vfd, coolant pump, mister along with inputs for e-stop, 6 limit switches
[01:35:42] <L33TG33KG34R> is the 7i76 enough for that?
[01:37:14] <jdh> should be.
[01:37:27] <jdh> do you really need individual limit switches?
[01:38:01] <jdh> plenty of inputs, but more wiring hassle
[01:38:23] <Valen> home switches perhaps
[01:38:46] <L33TG33KG34R> home switch + limit switch
[01:38:51] <L33TG33KG34R> for each axis
[01:39:06] <L33TG33KG34R> I am an ENT student so wiring isn't a problem
[01:39:15] <jdh> ear nose & throat?
[01:39:18] <Valen> you say that
[01:39:24] <Valen> but your wrong lol
[01:40:27] <L33TG33KG34R> you're* and no. You have no idea what they put us through
[01:40:35] <jp_> one limit signal per axis is more than enough
[01:41:07] <L33TG33KG34R> but in that extreme is the 7i76 enough? Also how would I interface the 7i76 with a VFD?
[01:41:14] <jdh> it has 32 inputs
[01:41:33] <jp_> analog perhaps or modbus if you have it
[01:41:51] <jdh> it has an analog spindle output also.
[01:42:02] <jp_> the &i76 has analog out for spindle purpose
[01:42:04] <jdh> it's like they designed the card just for this!
[01:42:08] <djdelorie> I wired all six limit switches to just one input
[01:42:40] <djdelorie> I think.... maybe one input per axis...
[01:42:48] <jdh> I did one per axis
[01:43:18] <jp_> looking at the machine can tell yo what one tripped anyways
[01:43:26] <skunkworks__> Valen: your idea of lsof | grep media worked great
[01:44:10] <jp_> anyone used kelling's stepper drives?
[01:44:41] <jdh> I have some
[01:44:49] <jp_> how do you like them
[01:45:08] <jdh> I got the cheap ones. Might have preferred the slightly better ones, but they work fine.
[01:45:16] <Tom_itx> i've used em
[01:45:25] <Tom_itx> the 282 in oz ones
[01:45:32] <Tom_itx> on my sherline work good
[01:45:37] <jdh> drives, or motors?
[01:45:39] <jp_> they are just re branded imports anyways aren't they
[01:45:43] <jp_> drives
[01:45:54] <jdh> they are rebranded leadshines?
[01:46:00] <Tom_itx> oh, i got gecko drivers

[01:49:12] <jp_> just looking for low cost units for small stuff
[01:49:27] <jdh> I thought about replacing mine, the better ones are cheap enough but the ones I have seem to work fine.
[01:49:28] <Tom_itx> they're probably fine for that
[01:50:11] <jp_> im sure they are i bought one of those small side steps for my extruder and they work great
[01:51:02] <Tom_itx> probably a better choice than the pololu's
[01:51:14] <Tom_itx> i hear they blow alot
[01:51:27] <Tom_itx> probably from stupidity but still

[02:18:16] <archivist_> I started the #kicad channel next door that probably makes me biased too
[02:18:53] <djdelorie> skorket: I'm one of the maintainers
[02:18:54] <jdh> pcb-ware-wars!
[02:19:13] <djdelorie> nah, try both and use whatever you want.
[02:19:25] <L84Supper> skorket, the pro world is pretty much Cadence vs Altium
[02:20:38] <archivist_> the last pro I used was dos PCAD, I still prefer it fo rease of use
[02:20:42] <L84Supper> I've been using Capture and Allegro for years for the most complex designs, but the cost is >$10K
[02:21:13] <skorket> yeah, I'm an amateur/hobbyist/poor person, so nothing that expensive for me
[02:21:28] <L84Supper> use whatever you like
[02:21:38] <jdh> eagle?
[02:21:41] <skorket> I remember picking geda a while ago but now I'm not sure why and I wanted to get some opinions
[02:21:52] <archivist_> eagle is limited pcb size
[02:22:02] <L84Supper> I see more open hardware designs that use Kicad
[02:22:10] <jdh> yeah, but I'm pretty limited.
[02:22:17] <L84Supper> for schematic capture
[02:22:33] <archivist_> watching the irc channel and I see steady growth in use
[02:23:47] <L84Supper> i hear that some people actually suffer through using it for hand routing very dense 3 mil trace/space PCB's
[02:26:05] <Tom_itx> i use eagle
[02:26:09] <L84Supper> the pro tools have lots of utils for automating, simulating and design rule checking
[02:26:36] <Tom_itx> i looked at pads
[02:26:57] <L84Supper> I'm also spoiled by large libraries vs virtually none for Kicad
[02:27:18] <Tom_itx> i've got well over 300 eagle libs
[02:27:58] <Tom_itx> majority of them are in the package now though
[02:31:11] <Thetawaves> did you get eagle standard?
[02:31:45] <Thetawaves> i have eagle light
[02:32:04] <Tom_itx> i paid for it years back and still use that ver for most of my stuff unless someone is asking for help
[02:32:05] <Thetawaves> i probably won't spend 600$ for 6 signal layers
[02:32:10] <Tom_itx> i have 2 or 3 ver loaded
[02:32:54] <Tom_itx> i've probably used it since ver 2 or so
[02:32:55] <Thetawaves> i make the footprint for roughly half my parts anyway, so switching to kicad shouldn't be that difficult
[02:33:02] <L84Supper> Eagle Light is only 2 layers max ?!
[02:33:07] <Tom_itx> yeah
[02:33:24] <Tom_itx> how many do you need?
[02:33:25] <L84Supper> oh only $69
[02:33:29] <Thetawaves> 'only two'
[02:34:00] <Tom_itx> if you're making 4 layer boards you're likely above the hobby level
[02:34:31] <Tom_itx> it's rather reasonable compared to pads or altium
[02:34:40] <djdelorie> I do many 4-layer boards, and it's hobby...
[02:34:57] <Tom_itx> i can do 16
[02:35:02] <Tom_itx> but haven't
[02:35:07] <L84Supper> whats PADS cost these days? <$10K
[02:35:10] <djdelorie> I've tested pcb with 56 layers
[02:35:22] <Tom_itx> that's just nuts
[02:35:38] <djdelorie> yes it was. I did a test board that was 0.25 miles on a side too. My house was very small on that one...
[02:35:45] <Tom_itx> but you get into BGA and that's what you get
[02:36:39] <djdelorie> on a 64-bit machine, I think pcb can do a board the size of our solar system...

[03:11:02] <L84Supper> etch 1-2 layers
[03:11:24] <Thetawaves> huh?
[03:11:26] <L84Supper> then you stil have to plate the vias and holes
[03:13:17] <s1dev> I wonder if anyone has looked into electroplating boards
[03:13:34] <s1dev> instead of etching
[03:15:37] <L84Supper> thats how multilayer boards are done, they sandwich core that's been plated and prepreg, then also plate the through holes and vias

[03:21:16] <Valen> they don't electroplate the copper onto the boards, its glued on
[03:21:19] <Valen> well epoxy
[03:21:32] <Valen> very hard to electroplate to stuff thats non conductive
[03:21:45] <Valen> i spose you might be able to do some kind of metal spraying
[03:23:27] <L84Supper> for microwave we use PCB cores made of teflon and fibergalss plated with copper
[03:23:53] <Valen> sure its plated not glued foil?
[03:25:00] <Tom_itx> my understanding is it's plated
[03:28:17] <L84Supper> I'm currently working on printing the traces directly onto 3d printed core layers, a 3d PCB printer that only uses fluids

[03:46:27] <L84Supper> basically they exposing the PTFE films to a sodium naphthalenide (Na/naphtha) etchant, and esterification of 4,4'-azobis(4-cyanopentanoic acid) (ACP) with the hydroxyl groups covalently linked to the surface, followed by the surface-initiated free radical polymerization of 4-vinylpyridine (4 VP)
[03:47:05] <L84Supper> it's not really plated directly to the PTFE since they modify the surface of the PTFE quite a bit first

[14:56:16] <FinboySlick> Mesa 5I25 is what I need if I just want something better than my board's parallel port, right?
[14:56:31] <JT-Shop> if it ain't right Maritool will make it right
[14:56:58] <JT-Shop> toss a 7i76 and a cable in and you have way more than a parallel port
[14:57:31] <JT-Shop> Jymmm: didn't read the source of the file when he downloaded it...
[14:59:10] <FinboySlick> JT-Shop: I'm still a bit confused as to which bit does what. I know mesa will go all the way to driving steppers. I don't think I'm up to replacing all the drivers in my mill yet but I'm looking into hardware stepgen.

[15:07:24] <skunkworks> with just the 5i25 you get 2 printer ports in effect but with high speed pwm/step-dir/encoder counters/ i-o
[15:08:01] <FinboySlick> That's pretty much what I need too. They're around 90 bucks, right?
[15:08:35] <skunkworks> with the daughter boards you get a lot more.
[15:08:57] <FinboySlick> Daughterboard would connect directly to my stepper drivers?
[15:09:04] <skunkworks> urd
[15:09:36] <FinboySlick> urd?
[15:09:41] <skunkworks> yes
[15:09:44] <skunkworks> and yes
[15:10:30] <FinboySlick> Hmmm, that would allow me to control a bunch of other things I guess.
[15:10:33] <skunkworks> daughter board gives you 5 axis step/dir outputs, 1 analog, 1 encoder interface and 48 i/o
[15:10:36] <skunkworks> and it is expandable

[19:32:07] <Jymmm> cradek: When doing a PCB, what is the narrowest area you've been able to get and with what tool? I need a clean/consistant 0.5mm or less gap
[19:34:19] <skunkworks> .007 with think/tink cutters..
[19:34:46] <Jymmm> skunkworks: Is that trace width, or space between traces?
[19:35:06] <skunkworks> space between traces
[19:35:07] <Jymmm> and is that in or mm?
[19:35:12] <skunkworks> in
[19:35:44] <Jymmm> 0.2mm that's not bad at a..
[19:36:18] <Jymmm> skunkworks: do you know which tink tool?
[19:37:49] <Spida> 0.2mm is what I get from my pcb manufacturer (etched)
[19:38:49] <skunkworks> Jymmm, give me a second

[20:00:29] <mrsun> can linuxcnc generate some kindof "timing file" or whatever one should call it, times etc that a stepper should step to to get the right velocity etc? :)
[20:09:06] <Spida> Jymmm: f-l.de
[20:09:27] <Kirk_Wallace> mrsun: If I understand your question, it seems you need to come up with the timing based on the manufacturer's data or you own testing.
[20:10:01] <Jymmm> Spida: thanks
[20:10:14] <mrsun> Kirk_Wallace, i mean like a for a buffer card that does all the stepping etc of the motors later
[20:10:42] <mrsun> sure motherboards still usaly have a header for parport but isnt it being kinda phased out ? :)

[23:12:10] <tjb1> No need for a screen to make things simple Loetmichel...
[23:12:10] <Loetmichel> tjb1: no, the screen with camery looks like a std tablet pc, maybe 100$ in extra cost and a bit soft

[23:13:48] <Loetmichel> and that helps in which way when expressing "get out of my way, i have to work"?
[23:14:07] <Loetmichel> i dont see the expensive
[23:14:13] <Loetmichel> the screen ist dirt cheap
[23:14:28] <Loetmichel> cheaper than a dedicated laptop anyway
[23:14:31] <tjb1> Dirt cheap is a 1x2 screen
[23:14:44] <tjb1> Not cheaper when you have 1,2,10,20 of these things
[23:14:54] <tjb1> 1 laptop versus 20 screens
[23:15:06] <L84Supper> they sell for $22K ea
[23:15:16] <Loetmichel> even then the laptop would be more expensive
[23:15:34] <tjb1> Laptops are $400...
[23:15:36] <Loetmichel> the screen will cost less than 20$ in quantities
[23:15:47] <tjb1> Yeah less than $20 to the company
[23:15:53] <tjb1> Not less than $20 to the person buying it
[23:16:04] <tjb1> Switch on my car cost me $13

[23:17:20] <tjb1> Its cheaper to dump the screen and whatever software and time they have in it and make it where you plug a laptop in or hit a button on the arm and teach it
[23:17:35] <tjb1> They are going to be trained for it anyway, simple light on it flashing can mean "Go away"
[23:18:20] <Loetmichel> [01:16] <Loetmichel> tjb1: i give up, one cant argue with ppl who wont accept any reason

[23:33:57] <JT-Shop> I didn't feel like wrestling a 6x6x1/4 x 20' square tube to the saw or the saw to the tube... so the torch came to the rescue
[23:34:36] <L84Supper> 20 inch or foot? :)
[23:34:41] <Tom_itx> foot
[23:34:42] <JT-Shop> foot
[23:35:06] <JT-Shop> I have 900 gallons of propane when all the tanks are full
[23:35:24] <JT-Shop> it's a 400lb beast
[23:35:53] <L84Supper> I just use the small propane tanks
[23:36:27] <L84Supper> the 330's are oxygen
[23:36:44] <JT-Shop> it would not be cost effective for me to switch, I might use it twice a year
[23:37:02] <L84Supper> my local menards always has stray tanks sitting out by the swap area
[23:37:42] <L84Supper> I get new full fresh tanks for the price of refills
[23:38:13] <L84Supper> not sure if people don't know how exchanges work or if they just drop of old tanks
