[00:00:00] <Jymmm> atom1: geckos have pins for the resistor
[00:00:11] <atom1> i see it in the pic
[00:00:34] <atom1> any wattage is ok i presume.. very little current draw on the sense resistor
[00:00:46] <Jymmm> Yeah, 5w is fine
[00:00:52] <atom1> 5W!!
[00:00:55] <Jymmm> err 1/2w
[00:00:57] <atom1> holy crap
[00:01:07] <atom1> i'm lookin at 1/8w or so
[00:01:20] <Jymmm> sure, I just like 1/2
[00:01:28] <Jymmm> 1/4 i mean
[00:01:34] <atom1> all the stuff i make is small so that's what i have
[00:01:42] <Jymmm> its all good
[00:01:44] <atom1> that or 0603 smt
[00:02:13] <Jymmm> if you have 1% use it, else 5%
[00:02:20] <atom1> now all i gotta do is sell a kidney for this shopping list
[00:02:43] <Jymmm> resistors are expensive there?
[00:02:50] <atom1> a bit overkill for a sherline mill
[00:02:53] <atom1> no
[00:03:03] <atom1> i'm sure i have resistors
[00:03:10] <atom1> maybe not 1%

[00:04:09] theorb is now known as theorbtwo
[00:04:10] <Jymmm> Every time I hit the surplus store, I grab a box or roll - they're free.
[00:04:38] <Jymmm> well maybe 5ft of a roll that is
[00:05:57] <Jymmm> one of these days I'll even have every value =)
[00:06:08] <atom1> no need really
[00:06:51] <Jymmm> It helps when playing with LED arrays
[00:07:26] <atom1> i think i'm going about this right. the first step was to calculate the max voltage the steppers could take
[00:07:35] <atom1> then find drivers that would take that voltage
[00:07:50] <atom1> that will allow me maximum step rates
[00:07:56] <Jymmm> what voltage is you motor?
[00:08:10] <atom1> depends how it's wired
[00:08:34] <Jymmm> what voltages is you motor?
[00:08:53] <atom1> just a sec..
[00:12:01] <atom1> http://tom-itx.dyndns.org:81/~webpage/motors/KL23H276-30-8B.pdf
[00:12:20] <atom1> eventually i'll probably wire it bipolar parallel
[00:13:19] <atom1> i figured ~50v max
[00:13:22] <atom1> just under
[00:13:30] <atom1> my supply is 50v no load
[00:13:36] <atom1> so it should be ok
[00:15:05] <Jymmm> parallel?
[00:15:20] <Jymmm> 4 wire
[00:17:10] <Jymmm> 48.25v

[00:20:52] <Jymmm> This input matches the G203V’s current output to the motor windings. The G203V will accommodate motor winding currents from
[00:20:52] <Jymmm> 0 to 7A. Use the following equation to calculate the value, (in kilo-Ohms) of the current set resistor:
[00:20:52] <Jymmm> R (in kilo-ohms) = 47 * I / (7 – I) Use the nearest standard value 5% tolerance, 1/4W resistor for this setting.

[00:22:09] <Jymmm> atom1: Pg 3 http://www.geckodrive.com/images/fck_uploads/G203V-REV-7-MANUAL.pdf
[00:22:13] <atom1> i assume even though you exceed the voltage rating of the stepper, you want to maintain it's current rating set by the driver current limit resistor
[00:22:26] <Jymmm> yes
[00:22:46] <Jymmm> 2.1 or 4.2 on your motor
[00:22:56] <atom1> so max current for bipolar parallel wiring would be 4.2A
[00:23:26] <Jymmm> so either:
[00:23:34] <Jymmm> g. 4A – 62.67K
[00:23:34] <Jymmm> h. 4.5A – 84.6K
[00:24:07] <atom1> you could likely calculate a value inbetween to get right at 4.2A
[00:24:17] <atom1> provided you can find a 1% resistor of that value
[00:24:25] <Jymmm> Round the appropriate answer to the nearest 5%
[00:24:25] <Jymmm> resistor value.
[00:24:33] <Jymmm> right out of the manual
[00:24:36] <Jymmm> 5%
[00:24:39] <atom1> yeah
[00:24:49] <atom1> i have those here
[00:24:54] <atom1> for the 201 as well
[00:25:41] <atom1> how do you calculate the maximum step frequency you can use?
[00:25:56] <atom1> on the stepper side of things... not the computer
[00:27:01] <Jymmm> I dont know what you mean
[00:27:26] <atom1> the maximum step rate before the rotor mass stalls out
[00:27:32] <Jymmm> it's 1.8 deg/step which is 200 SPR
[00:27:45] <Jymmm> got a torque curve?
[00:29:25] <atom1> http://www.kelinginc.net/KL23H276-30-8BT.pdf
[00:29:33] <mozmck1> yeah, figure how much torque you need and look at the curve.
[00:30:26] <Jymmm> what mozmck1 said
[00:31:04] <Jymmm> Note the curve says HALF STEP and at 30V
[00:31:31] <Jymmm> so take those into account
[00:32:12] <atom1> yeah, it'll probably be trial and error. i'm not sure how much torque i need per axis
[00:33:18] <atom1> i'm not looking for breakneck max performance. i'm just learning how to figure it
[00:34:03] <atom1> i'm sure heat becomes a factor at some point
[00:35:32] <mozmck1> I think the heat is mostly a function of the current.
[00:36:07] <mozmck1> Steppers on geckos that are just idling can build up a good bit of heat.
[00:36:43] <mozmck1> they do get hotter in use though.
[00:37:03] <atom1> i thought some of them had cutback circuitry for idle conditions
[00:38:02] <mozmck1> some of them may. I know some of the older ones the motors would warm up a good bit.
[00:38:21] <atom1> yeah, right now mine get warmer when sitting idle
[00:38:42] <atom1> ?Recirculate mode while motor is stopped
[00:38:47] <atom1> whatever that is

[02:40:54] <The_Ball> What switch kind is the way to go for diy retrofitting? I'm guessing optical switches over micro switches?
[02:41:29] <atom1> the take on that is they all have their drawbacks
[02:41:54] <jdhNC> for limits, it doesn't really matter does it?
[02:42:22] <jdhNC> for homing... something repeatable then home on z encoder
[02:43:41] <atom1> the encoder itself is an optical switch
[02:44:59] <jdhNC> hmm... do you usually get a Z out of a resolver?
[02:46:13] <The_Ball> I've got index on x/y but not z-axis
[02:47:21] <jdhNC> different z
[02:47:51] <The_Ball> isn't z index? channel a/b/z
[02:48:01] <jdhNC> heh, yeah
[02:48:27] <jdhNC> I just saw 'z-axis'
[02:49:19] <The_Ball> what's the drawback of optical gates?

[02:54:14] <Connor> What's a good source to get Aluminum ?
[02:54:28] <atom1> australia
[02:54:34] <atom1> the largest supplier in the world
[02:54:38] <jdhNC> I prefer raw bauxite
[02:54:41] <atom1> :D
[02:55:00] <atom1> i have a local surplus that has a goldmine of aluminum
[02:55:12] <jdhNC> depends on what you want and how fast you want it... there's a salvage/recylce place here that lots of good stuff
[02:59:03] <Connor> not in any hurry.. just looking for a general supplier.
[02:59:16] <atom1> what country?
[02:59:20] <Connor> US

[14:49:42] <tom3p> someone asked on the list about spoon feeding emc. doesnt emc have to process the entire file beforehand?
[14:51:08] <cradek> you can give emc one mdi command at a time, or you can let it open the whole file. those are the only two ways to run it.
[14:51:31] <cradek> someone who wants to drip feed emc is probably confused about something
[14:51:43] <tom3p> ok, like exact stop mode/mdi
[14:52:10] <tom3p> (i mean each indiv line is execd separately in the mdi scenario )
[14:52:11] <cradek> (I didn't see this question)
[14:52:30] <cradek> instead of giving an answer, I suggest trying to figure out what the real question is
[14:52:59] <tom3p> speakertodirt asked it posting titled "[Emc-users] Fw: Re: Shizuoka and Bandit Controller"
[14:53:14] <cradek> he was asking about using emc to drip feed a bandit
[14:53:34] <cradek> ... which shows a misunderstanding about what emc is/does, and maybe also other misunderstandings
[14:54:17] <tom3p> oh yeah, he wants to feed the bandit, my bad
[14:59:22] <skunkworks> odd
[15:00:37] <anonimasu> heh
[15:00:43] <JT-Shop> he just needs a program like dnc or what ever it is called
[15:00:43] <anonimasu> I see..
[15:00:47] <anonimasu> why not predator dnc or something
[15:01:15] <tom3p> about feeding the bandit? many people are used to small memory systems, and expect large programs need spoon/drip feed to circumvent the small mem.
[15:01:33] <tom3p> the bandits were 6502 when i worked on e,
[15:01:40] <tom3p> em
[15:03:23] <archivist> did you lot read the question, he want it to be emc like but then feeding the bandit
[15:05:22] <archivist> I would go with retrofit but with connectors so swap to new controller is fast and un-doable

[15:38:06] <Connor> right.

[16:08:23] <cradek> for MT drill bit holders, I wonder if you could buy cheap (hardened, ground) MT2-to-something adapters and turn off whatever you don't want.
[16:08:56] <cradek> making a good MT is harder than paying a few bucks for something to cut up
[16:10:48] <cradek> http://www.shars.com/products/view/233/MT2_J2_Drill_Chuck_Shank
[16:11:48] <ssi_> I thought abaout that
[16:11:49] <archivist> or mt2 blanks that have soft end for making any whatever
[16:12:02] <ssi_> I figured cutting an MT under CNC would be relatively trivial
[16:12:52] <ssi_> I made an MT4.5 to 5C spindle nose adapter for my big lathe by hand
[16:13:46] <cradek> never heard of MT4.5 - ouch
[16:13:55] <ssi_> haha
[16:14:05] <ssi_> my old clausing 6300 is MT4.5 inside the spindle nose
[16:14:09] <ssi_> it's basically a short MT5
[16:14:11] <cradek> MT2 is pretty small
[16:14:17] <ssi_> 1-3/8" through the bore
[16:15:12] <archivist> you will discover any errors when it fails to stick in the taper properly :)
[16:15:19] <cradek> exactly
[16:15:19] <tom3p> i just started using Shars, they're next town down river, pretty quick
[16:15:45] <cradek> why not try cutting one, and blue it up and see if it's the right shape
[16:16:40] <archivist> tool will need to be dead on centreline
[16:17:34] <archivist> and the height change I get on my old southbend makes for added joy
[16:19:11] <cradek> the whole time, keep in mind that for $4 you get one the right shape, hardened and ground, with a tang
[16:19:40] <cradek> (well, assuming shars stuff is hardened)
[16:19:45] <cradek> it will probably be the right shape.
[16:20:11] <tom3p> if its inductioned hardened then rear is hard & ground usually and front is machineable
[16:20:33] <tom3p> look for the blue band
[16:32:46] <ssi_> all that is fantastic, but it still doesn't answer my question ;)
[16:33:36] <cradek> sometimes you don't get exactly what you ask for - sometimes you even get something better :-)
[16:33:54] <ssi_> sometimes!
[16:33:58] <cradek> haha
[16:34:11] <ssi_> it doesn't help for the TTS holders though

[17:41:19] <jdhNC> yep
[17:41:41] <archivist> and define high speed

[17:41:47] <jdhNC> ~20k/hour
[17:42:09] <jdhNC> guess that's not so high speed really
[17:42:20] <jdhNC> 6/second
[17:43:13] <archivist> ah low speed, three choices, capacitive proximitry, inductive, or optical, first two will be more reliable, optical hates dirt
[17:43:45] <JT-Shop> I always thought optical was a dirt magnet somehow
[17:44:02] <jdhNC> err... they aren't really stainless. Just the samples are.
[17:44:16] <archivist> metal wont mater too much
[17:44:20] <jdhNC> they are nonferrous metallic balls
[17:44:27] <jdhNC> in a stainless tube
[17:44:35] * JT-Shop goes to clean the plasma table off
[17:45:09] <Connor> That's pretty cooll.. guy made a virtual CNC
[17:45:45] <jdhNC> any off-the-shelf thing?
[17:46:26] <archivist> the tube acts as a faraday shield, do you mean non rusting instead, eg plastic
[17:47:50] <jdhNC> the ball is non-rusting metallic
[17:47:52] <jdhNC> not plastic
[17:48:59] <archivist> bronze, stainless are the two Ive seen most, also seen plated brass
[17:49:03] <jdhNC> I was thinking of a fiber through-beam with the slits in the tube
[17:49:45] <archivist> you may need to clean the tube on a regular basis with optical
[17:50:12] -!- isssy [isssy!~isssy@78-83-51-185.spectrumnet.bg] has joined #emc
[17:52:13] <archivist> if tube was plastic with a small coil around the inductance would change as the ball passed though
[17:52:32] <Connor> What is all this for ?
[17:52:57] <archivist> the man said counting balls
[17:53:09] <Connor> Yea, but.. why? :)
[17:53:41] <fragalot> why not?
[17:53:53] <archivist> I think a bean counter wants it so
[17:55:35] <fragalot> tbf, capacitive or inductive would be the best way to go, depending on the material
[17:56:04] <fragalot> or possibly magnetic (hall sensor?) if the material allows for this
[17:56:56] <archivist> magnetic may cause buildup of shite and blockage
[17:57:09] <fragalot> hall sensor itself isn't magnetic afaik
[17:57:13] <awallin> archivist: I made a bit of progress with interfacing the cutsim with an OpenGL VBO. That seems to be fast enough. It's using Qt right now, but if there's another c++ toolkit with OpenGL that comes with emc2 then switching shouldn't be too hard. I guess I would need help from someone who knows the g-code -> interp -> canon-commands parts of emc2
[17:57:28] <fragalot> but the metal balls passing by change the magnetic field so...
[17:58:01] <archivist> fragalot, then there is a magnet, and brass balls
[17:58:34] <fragalot> you're the one that mentioned brass
[17:58:50] <fragalot> jdhNC just said "some non-rusting metal" .. could be anything really :p
[17:58:55] <archivist> inductive should work regardless of ball metal
[17:59:00] <fragalot> yeah it should
[18:02:34] <archivist> jdhNC, we have a part time visitor in here trying to make a ball sensor at the moment
[18:07:44] <pcw_home> Inductive could even work through a thin metal tube
[18:09:04] <pcw_home> especially stainless or some other high Ohmic resistance metal
[18:09:47] <archivist> http://www.sensource.biz/products/proximity-sensors/ nut the small size is the fun part
[18:09:56] <archivist> nut/but
[18:10:38] <jdhNC> it's not brass
[18:11:20] <Connor> jdhNC: Is this a closed system ? I.E. can dirt get introduced into it ?
[18:11:43] <Connor> If not, go with a slot style photo/ir sensor and be done with it.
[18:11:48] <jdhNC> it is closed, but I assume over time, there will be stainless dust
[18:12:11] <jdhNC> I can slot the tube, or possibly make an acrylic transition
[18:12:12] <Connor> not enough to cause issues..
[18:12:54] <Connor> this some sort of bearing?
[18:13:36] <jdhNC> it has the appearance of a stainless ball bearing
[18:13:57] <Connor> jdhNC: No, I mean the application.. what's this for?
[18:13:57] <jdhNC> I'm not being obnoxiously obtuse, I just can't say.
[18:14:03] <Connor> oh.
[18:14:33] <jdhNC> it is to count N balls into a container
[18:14:46] <jdhNC> which has been done many times before I'm sure.
[18:15:19] <tom3p> if all .25" and same material, can you use weight?
[18:15:22] <archivist> at high rates one has to take into account the balls in flight :)
[18:15:37] <jdhNC> they will be trapped in a tube

[18:19:55] <jdhNC> right
[18:20:09] <archivist> its knowing the right google term
[18:20:21] <grommit> Hi. I have a question about a limit switch and EMC. Let's say I have a heavy mill that takes .3" to stop an axis due to the mass and momentum of the moving table. If the table contacts a limit switch, which then signals to stop, and the table stops - but has moved 0.3
[18:20:31] <grommit> oops, didn't finish...
[18:21:04] <Connor> Oh. I though you were going to try to make it from components.
[18:21:14] <grommit> - but has moved 0.3", and the switch now de-activates. Will it re-trigger the limit as it passes back the other way?
[18:21:14] <archivist> jdhNC, http://www.balluff.com/Balluff/de/NewsChannel/News/en-gb/Inductive+ring+sensors+BES+IKVS.htm
[18:21:38] <grommit> Or does EMC have logic in it that knows the direction of travel and hence won't re-signal a limit condition?
[18:21:40] <cradek> grommit: set up your limit switch so it stays engaged all the way to the end of travel
[18:21:52] <DaViruz> long cam
[18:22:02] <cradek> you should never be able to get on the wrong side of a limit switch. if you can, the switch is not set up properly.
[18:22:03] <Connor> other possibility might be some sort of air flow sensor.. as the ball passes, it blocks air flow, you have something that counts the pulses of air.
[18:22:04] <DaViruz> (for instance)
[18:22:06] <jdhNC> archivist: those are cool, we use them for tube detection. Not sure they can see the material inside the tube though
[18:22:19] <grommit> Ok, I was afraid of that.
[18:22:30] <grommit> back to the drawing board on my switch :-)
[18:22:35] <archivist> jdhNC, hence why I mentioned a plastic tube part
[18:22:46] <cradek> it would be wrong of emc to do ANYTHING but stop if a limit switch is hit
[18:22:46] <DaViruz> in principle it would probably be possible to set up separate limit switches that only blocks a specific direction
[18:22:54] <DaViruz> and stay locked untill you pass it in the opposite direction
[18:22:55] <cradek> it is wrong to assume you know what's happening
[18:22:59] <grommit> Yeah, you're right.
[18:23:29] <grommit> Thanks.
[18:23:33] <grommit> I guess ;-)
[18:23:35] <cradek> welcome, good luck :-)
