[00:15:36] <nsp> do they work ok? I looked on youtube and someone looked like they just did a standaard parallel port setup and normal prepackaged settings
[00:15:43] <nsp> with very little setup trouble
[00:15:54] <nsp> i got a few free laying around and thinking of making this annirouter
[00:16:08] <CaptHindsight> they are for small steppers
[00:16:15] <CaptHindsight> also noisy
[00:20:15] <nsp> i saw a guy run them with nema 23

[00:30:03] <kengu> what kind of voltages you can run with those tb6560 ones
[00:31:53] <nsp> so u can run those other drivers off of the built in drivers on the tb6560 if you want to go higher?
[00:36:15] <nsp> or is that just the motor driver with a built in pcb
[00:36:23] <nsp> ah i see its just the chip?

[00:39:41] <nsp> I see, thanks tom
[00:40:28] <Tom_itx> maximum
[00:41:09] <nsp> anybody have any idea on how to calibrate a scara arm
[00:41:32] <Tom_itx> there have been a couple here with them
[00:42:19] <nsp> ya, ive got mine all set and wired up. I can get it to move when i tell it to and it shows up in lcnc but the pid isnt tuned and the revs per joint arent tuned to the correct values
[00:42:34] <TekniQue> it's a bit retarded that the specs on that ebay listing don't tell you what kind of voltage that thing tolerates
[00:43:42] <Tom_itx> i didn't read far enough to know about clamping diodes on the outputs either
[00:45:32] <nsp> its weird for my motors i should be able to find encoder tics per rev and just set that number but the motors are too hard and old to find exactly what model they are
[00:45:40] <nsp> ive found similar but not the exact one
[00:47:47] <CaptHindsight> TekniQue: there are a bunch of boards with similar designs, some don't even have data sheets just the PCB silkscreen with G, 24V+, A- A+ B- B+ etc etc

[00:51:38] <TekniQue> I blew up a chinese stepper driver by overvoltage
[00:51:46] <TekniQue> it used some integrated circuit
[00:52:35] <CaptHindsight> probably tb6560, they destruct if you remove the motor leads when under power
[00:55:10] <CaptHindsight> http://www.sainsmart.com/3d-printing/3d-printing-modules/sainsmart-a4988-stepper-motor-driver-3d-printer-carrier-for-reprap-ramps-prusa.html
[00:55:12] <TekniQue> my engine dyno uses a nema23 motor to turn a ball valve that adjusts the water flow through the water brake
[00:55:21] <CaptHindsight> lots of these in the reprap world
[00:55:49] <TekniQue> and when I was testing that out with a variable power supply I found it worked smoothest with lots of voltage
[00:55:54] <TekniQue> before the driver blew up
[00:56:19] <TekniQue> so I ended up using a 48V power supply when I rigged it up
[00:56:25] <nsp> lol
[00:56:42] <TekniQue> and got a driver with enough voltage rating
[00:57:12] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/kl-stepper-drivers these are about 1,000,000 times better for a few $$ more
[00:57:44] <TekniQue> KL-5056 is what I use now
[00:57:44] <CaptHindsight> well 1,000 x at least
[00:57:59] <nsp> whats the difference in the circuitry
[00:58:11] <CaptHindsight> better design
[00:58:16] <TekniQue> nsp: these use discrete mosfets for the drive

[00:58:58] <CaptHindsight> where they are actually from
[00:59:02] <nsp> instead of the tb6560 is actually an ic chip used for the drive for the other driver?

[18:03:34] <eric_unterhausen> I'd like to follow the residential code
[18:04:08] <CaptHindsight> eric_unterhausen: unless you're on a town that has lots of code variances just check the current NEC
[18:04:10] <jthornton> codes vary from state to state unless you follow the national electrical code
[18:04:18] <jthornton> we have no codes here
[18:04:40] <eric_unterhausen> I think we are following the NEC from 1950 or so
[18:05:09] <eric_unterhausen> I tried to get Cletus to put gravel under my deck, they only did about 1/4 of it, inspectors didn't care
[18:05:19] <CaptHindsight> how many conductors? what insulation and what size conduit are you using?
[18:05:48] <eric_unterhausen> I have 6 14AWC, 3 12AWG and 4 10AWG
[18:05:56] <eric_unterhausen> right at 40% the way I calculate
[18:06:13] <CaptHindsight> how many are current conducting?
[18:06:38] <CaptHindsight> or is this just for signals?
[18:06:40] <eric_unterhausen> I have 4 grounds
[18:07:14] <eric_unterhausen> and 2 neutrals on 220 single phase. does that make a difference?
[18:07:17] <CaptHindsight> nevermind, 10ga signal would be silly
[18:07:58] <CaptHindsight> yes, fill is based on physical volume, wire insulation and current carrying conductors

[18:11:24] <IchGuckLive> hi all B)
[18:11:38] <eric_unterhausen> how much derating?, I'm at 25%
[18:12:06] <CaptHindsight> I dropped my license ~29 years ago, but it's something like 25 or 30%
[18:12:09] <eric_unterhausen> actually 30%
[18:12:46] <CaptHindsight> is any of it 3 phase wye?
[18:14:11] -!- AR_ has quit [Ping timeout: 272 seconds]
[18:14:16] <CaptHindsight> wye counts the neutral as a conductor if there are any non-linear loads that cause harmonics such as switching power supplies
[18:15:20] <CaptHindsight> so depending on how long the runs are it's sometimes cheaper to run more conduit and less copper
[18:15:22] <eric_unterhausen> no, it's all single phase
[18:16:52] <CaptHindsight> with single phase 120/240 the lines count as a conductor each and the neutrals don't count
[18:17:16] <eric_unterhausen> looks like I'm ok, although I don't have a NEC handy
[18:17:52] <CaptHindsight> the problem you can still get into is if you don't share/balance the neutrals

[18:21:30] -!- Tecan has quit [Read error: Connection timed out]
[18:21:51] <CaptHindsight> the two 120V lines sharing a neutral should be from opposite lines, so 240V when measured across them
[18:22:03] -!- Tecan [Tecan!~fasdf@unaffiliated/unit41] has joined #linuxcnc
[18:23:30] <CaptHindsight> if you have two 120V lines (even though from separate circuits/breakers) sharing a neutral the neutral can have 2X the current (the sum of both circuits) vs just the imbalance
[18:24:15] -!- PetefromTn has quit [Remote host closed the connection]
[18:25:16] <archivist> just think about that :)
[18:25:18] <CaptHindsight> so even though the lines have current protection say at 20A the neutral will have 40A on it at full load vs 0A if balanced
[18:25:29] <IchGuckLive> better to go 400V
[18:26:14] <IchGuckLive> oh the US got only 110 in the Net
[18:26:42] <archivist> US has a broken mains system
[18:27:06] <IchGuckLive> it still has powerlines on top of the earth
[18:27:20] <IchGuckLive> avery snow storm breaks the ingeners neck
[18:27:29] <CaptHindsight> the US used to be mostly 120?240 delta

[18:38:37] <eric_unterhausen> I am not sure having 120 v single phase is a problem

[18:39:52] <eric_unterhausen> my understanding is that the tranformers at the street are single phase
[18:40:09] <IchGuckLive> yes but on 2lines
[18:40:14] <IchGuckLive> 3lines
[18:40:34] <IchGuckLive> so you got 3 120V to the House 1 N and one Gnd
[18:40:36] <eric_unterhausen> still single phase in/single phase out
[18:41:01] <IchGuckLive> if you use only the 3 lines L1 L2 L3 you got 240
[18:41:09] <IchGuckLive> within them
[18:41:12] <eric_unterhausen> to get 3 phase costs quite a bit unless you are in an industrial area
[18:41:13] <CaptHindsight> for residential it's 3 wires, 120/208, 2 poles and the center neutral
[18:41:19] <IchGuckLive> no N Blue requiered
[18:42:05] <IchGuckLive> o i need to get of this as i never lived in the states only 6month as i wars young and that is quite a time
[18:42:26] <eric_unterhausen> looks like I am supposed to derate 20% for up to 6 conductors
[18:42:37] <IchGuckLive> but your oven in the kitchen shoudt got the 3 lines
[18:43:02] <eric_unterhausen> code requires 3 lines plus ground for oven/stove
[18:43:10] <eric_unterhausen> unless the locale is behind the times
[18:43:22] <CaptHindsight> for older homes you might still have 120/240, 3 wires, 120..neutral..120 from a delta
[18:44:13] -!- i_tarzan has quit [Ping timeout: 240 seconds]
[18:44:37] <CaptHindsight> eric_unterhausen: yeah. continuous maximum load should not be more than 80%
[18:45:07] <CaptHindsight> so no 19A on a 20A breaker
[18:45:48] <eric_unterhausen> my loads are much less than the rating of the circuit

[19:11:18] <eric_unterhausen> I think everything stayed the same up until 2009

[19:55:22] <eric_u_cnc> it's 3.4.55-rtai-2 #1 SMP PREEMPT

[20:00:20] <eric_u_cnc> how do you tell what video driver is running?

[20:03:12] <eric_u_cnc> I had a usb flash drive in, doesn't that screw things up sometimes?

[21:05:03] <eric_unterhausen> after all that navel-gazing about conduit, I decided it wasn't a good idea
[21:06:10] <eric_unterhausen> and putting up more conduit is made more difficult by the placement of the radon mitigation system piping
[21:06:43] <skunkworks> eric_unterhausen: you could try a few things.. disable lagecy usb, and the sound card in the bios..
[21:06:59] <skunkworks> Try adding idle=poll to the kernel line..

[21:31:34] <eric_unterhausen> I guess I should go downstairs and try again
