[09:43:47] <Valen> got a friend with a stepper machine he is trying to get working, he has X axis running with 2 motors chained together in EMC however sometimes when he does a rapid only one motor moves. At the moment, the motors aren't in the machine so i presume its not mechanical

[14:00:33] <JT-Shop> I've used a 1" extruder to make collated nails
[14:02:12] <atom1> well at least i got boards ordered
[14:07:36] <JT-Shop> which ones?
[14:07:57] <atom1> 7i43 and 7i47
[14:09:15] <JT-Shop> cool
[14:09:49] <atom1> tryin to figure out the best way to make a pendant now
[14:12:48] <JT-Shop> is your machine big enough for a pendant?
[14:13:05] <atom1> why not?
[14:13:13] <atom1> it would be handy
[14:13:29] <atom1> how does emc jog otherwise?
[14:13:34] <atom1> i haven't used it yet
[14:15:20] <atom1> i'm trying to get stuff i can expand with
[14:15:26] <atom1> to a larger one eventually
[14:18:05] <JT-Shop> what I meant was do you need a pendant on a cord? they are clumsy to use... a fixed place with MPG and selectors seem to be easier to use on smaller machines like my VMC and CHNC
[14:18:49] <atom1> oh, well i was thinking the same thing. i may find a place to mount it in an enclosure of some type
[14:19:12] <atom1> mainly i want a jog wheel of some type
[14:19:26] <atom1> i'm tired of using the keyboard for that
[14:19:31] <JT-Shop> the only machine I have with a pendant so to speak is my plasma table as I need to be all over it when jogging to line up and the computer is not near the machine but a fixed mount would be better even for that
[14:20:30] <JT-Shop> on the VMC I have a MPG and two selector switches next to the MPG one for axis selection and one for increment to move per click of the MPG
[14:20:53] <atom1> yeah that's what i'm looking at
[14:21:13] <atom1> maybe an avr with an lcd display on it
[14:21:29] <atom1> just borrow the signals for the display
[14:23:37] <JT-Shop> I find I'm not looking at any display when I jog with the MPG but are watching the tool
[14:23:53] <atom1> i'd agree with that
[14:25:08] <atom1> it's nice for stuff like when you use a wiggler to find the edge then you can move over the .1" to center
[14:26:08] <atom1> i'll probably hook it up without to try then see how bad i want it then
[14:26:33] <atom1> i've got all the stuff to add it anyway
[14:31:00] -!- Valen [Valen!~Valen@ppp121-44-231-147.lns20.syd7.internode.on.net] has joined #emc
[14:31:53] <atom1> i was thinking about putting a couterweight on the z since the motor sits off to one side on this thing
[14:39:59] <JT-Shop> when I find an edge I just enter the offset for where I'm at
[14:40:49] <JT-Shop> for example I'll use a 3/8" dowel pin and get the tool closer to the part than 3/8 and back off till the dowel just slips by then set my offset
[14:41:06] <atom1> on my current program i zero the axis for the g54
[14:41:24] <atom1> right
[14:41:37] <atom1> we kept a dowelpin in one of the tool holders just for that
[14:42:15] <atom1> i use a wiggler with the spindle on slow
[14:44:46] <JT-Shop> on my mill I have a 1/2 dowel and move it to -0.25 of where I want the X edge of the part to be then slide the part up to the dowel and tighten the vise, no edge finding needed
[14:45:07] -!- Valen has quit [Quit: Leaving.]
[14:45:08] <JT-Shop> the dowel is in the spindle
[14:45:42] <atom1> yeah that works good for production where you have a tool changer
[14:45:46] <atom1> this doesn't have one
[14:45:58] <atom1> we did it the same way
[14:46:52] <JT-Shop> I used to keep it in the tool changer but now I just keep it on the bench and swap when I need to set the edge of the part
[14:47:22] <atom1> setting tools on a boss5 was fun
[14:47:41] <atom1> no changer.. just lay the tools out on the table and change them manually
[14:48:14] <mrsunshine_> yeey casting was good enough =)
[14:48:21] <atom1> that thing had the old tape reader interface on it
[14:48:25] <mrsunshine_> faced the surfaces now and it looks good enough =)
[14:48:34] <mrsunshine_> tho a tad bit much gas inclusion :/
[14:49:35] <archivist> sand a bit too damp?
[14:50:37] <mrsunshine_> archivist, yeah i think it was, and the puring didnt go as planes either, ALOT of airtime for the metal
[14:50:59] <JT-Shop> atom1: my BP series 1 with Kwik Switch spindle is like that too
[14:51:25] <mrsunshine_> oh well, the casting will be able to hold a couple of tonnes of force anyways, and all its supposed to do is hold the motor in the air :P
[14:51:26] <atom1> i suppose i should be looking for an enclosure for the supply and boards now
[14:54:22] <JT-Shop> are you going to use a nema style enclosure?
[14:54:58] <atom1> i'll probably just make something for this
[14:55:20] <atom1> it would be nice to get a proper one
[15:00:38] <JT-Shop> you can borrow my plasma table and brake to make one... but you have to come to Swamp East Missouri to use it :)
[15:01:25] <atom1> i was trying to think of some electrical box that might be suitable
[15:01:34] <atom1> but haven't come up with anything yet
[15:04:28] <JT-Shop> you can get a box from homless depot with a screw mount cover for a few dollars
[15:05:01] <atom1> i'll check around and see what's out there
[15:05:19] <atom1> once i get all the pieces and figure out how much room i need

[15:10:17] <JT-Shop> yuk, raining again
[15:12:59] <atom1> when are you gonna start moving machines in?
[15:13:20] <atom1> must be getting close
[15:20:22] <JT-Shop> I have to get the walls covered with OSB... was going to pick some up today but raining again
[15:21:07] <JT-Shop> put in the garage door, tape and mud the ceiling and paint everything then moving machines
[15:21:19] <JT-Shop> closer that I ever was :)
[15:21:41] <Jymmm> no electrical/air?
[15:23:16] <Jymmm> JT-Shop: no electrical/air?
[15:23:46] <JT-Shop> well after painting I have to put the outlets in the boxes
[15:24:05] <JT-Shop> all 47 of them
[15:26:03] <Jymmm> JT-Shop: plumbing air too ?
[15:27:26] <JT-Shop> surface mount all the air piping
[15:30:06] <atom1> i wonder if thickwall copper is heavy enough for that
[15:30:27] <atom1> would be easy to rough in
[15:31:28] <JT-Shop> for air?
[15:31:32] <atom1> yeah
[15:31:40] <JT-Shop> be much too expensive
[15:31:42] <atom1> i've seen it done but not tried it
[15:31:52] <atom1> i ran iron thru the attic and dropped it
[15:32:07] <atom1> with a flex hose at the compressor
[15:33:02] <mrsunshine_> hmm, i find clamping stuff hard :/
[15:33:03] <mrsunshine_> sigh
[15:33:08] <JT-Shop> I'll use black iron for the main trunk line

[18:42:19] <mrsunshine_> i dont get it, how can a 3nm stepper have the exact same electrical ratings as a 8.5nm ? :)
[18:42:57] <awallin> more/bigger permanent magnets?
[18:43:05] <mrsunshine_> awallin, hmm true =)
[18:43:07] <awallin> or less...
[18:43:12] <mrsunshine_> its nema34 insted of nema23 frame also
[18:43:17] <mrsunshine_> so i guess alot of stuff can be alot bigger
[18:44:37] <awallin> but I guess in the end electrical power input will determine mechanical power out
[18:44:44] <awallin> otherwise it would be black magic :)
[18:45:25] <awallin> so you can't spin the bigger motor at the same rpm and get a bigger torque out with the same electrical input which makes the smaller motor go that same rpm at a lower torque
[18:45:27] <awallin> or something...
[18:45:51] <mrsunshine_> awallin, well the 3A ones wants 2V 4.2A, the 8.5nm wants 2V 4.2A
[18:46:14] <awallin> right. do you have an rpm vs. torque curve?
[18:46:35] <awallin> and those voltages are some nominal crap. you should have drives at 70V or 90V anyway to get good acceleration
[18:46:55] <mrsunshine_> awallin, aye ... running mine at 40V atm
[18:48:07] <mrsunshine_> but looks to me like the page has got it wrong as the datasheet says 6A for bipolar
[18:48:20] <mrsunshine_> while the page where i can buy them says 4.2 at bipolar
[18:48:24] <JT-Shop> atom1: my selector switches?
[19:05:17] <mrsunshine_> http://www.soigeneris.com/NEMA_23_Stepper_Cover-details.aspx anyone know if i can find these somewhere inside of EU ? :)
[19:10:15] <Connor> atom1: I got my breadboard wired up with the 128x64 LCD, a Rotary switch and a few push buttons to work on the core software for the pendant.
[19:10:38] <atom1> JT-Shop yes
[19:11:06] <atom1> Connor, are you sending switch signals out the avr from the adc input?
[19:11:35] <atom1> i considered doing it that way not knowing if i have adc available as an input to emc
[19:11:36] <Connor> Yes, I had too.. I have 2 ADC's free though.
[19:11:39] <atom1> i don't think i do
[19:11:56] <atom1> so you just use avr pins as switch out
[19:12:14] <Connor> Wait.. What exactly are you asking?
[19:12:27] <atom1> how does emc know what switch is on?
[19:12:35] <Connor> Oh. I'm not that far yet.
[19:12:36] <JT-Shop> the 0.0001 no input, 0.001 and 0.01 input to the 7i37
[19:12:52] <JT-Shop> the X and Z axis input to the 7i37
[19:13:08] <Connor> Right now, just working on getting the software and menus done..
[19:13:11] <atom1> JT-Shop, the 7i47 doesn't allow adc input or i'd do it like Connor is
[19:13:21] <Connor> OH.
[19:13:27] <atom1> how far are you on the menus?
[19:13:30] <Connor> You want to use a Rotary switch with analog.
[19:13:37] <atom1> well i may
[19:13:51] <atom1> i have plenty of avrs for that
[19:14:03] <atom1> but i don't have a card with adc to get it to emc
[19:14:38] <atom1> so i'll probably for now just use the switches or send the adc to the avr and fake switches with a couple output pins
[19:15:16] <atom1> local guy had some 10 position switches but i didn't like em
[19:15:51] <Connor> Mouser had those 12 position ones that you can set the limit on.
[19:15:59] <atom1> i know
[19:16:14] <atom1> i gotta get some other stuff from digikey pretty soon so i'll grab a couple from them
[19:16:17] <Connor> I wrote a really nice AVR function to read the ADC pin and output a 0-# for the selection
[19:16:25] <atom1> mouser doesn't stock what i need or i'd get it from them
[19:16:37] <Connor> Yea, I have to issue sometimes..
[19:16:38] <atom1> i'll steal your code then
[19:16:39] <atom1> :D
[19:16:57] <atom1> i've got menu code but i don't like it
[19:17:10] <atom1> for now i prolly won't use an lcd yet
[19:17:17] <Connor> I ordered the MPG, should be here next few days.
[19:17:20] <atom1> i'll test the wheel without
[19:17:24] <atom1> i'll order one today
[19:17:50] <atom1> i'm in no hurry
[19:18:23] <atom1> if it gets here i'll have to get off my butt and do something and i'm feelin lazy atm
[19:19:11] <atom1> i had my psu board all layed out then this thing crashed and i lost it
[19:19:18] <atom1> i should have done it on my main pc
[19:22:02] <Connor> I'm having allot of fun playing around with the LCD.
[19:23:04] <atom1> you should look at an oled
[19:24:10] <Connor> My hope is to have a framework setup so that someone else can use this code and write their own code for their machine.
[19:24:27] <Connor> With that in mind.. I'm laying out my menus and screens now..
[19:24:47] <atom1> you're using arduino right?
[19:24:49] <Connor> Any input on what the main screen needs to show.. and how to indicate which axis is selected ?
[19:24:51] <Connor> Yea
[19:24:54] <atom1> pfft
[19:25:01] <Connor> Arduino IDE anyway.
[19:25:13] <atom1> i'll just code mine in c if i use one
[19:25:18] <Connor> I'm using my custom piggy-back AVR
[19:25:45] <atom1> i don't like having the workings hidden from me
[19:25:57] <Connor> why pfft on Arduino? It's easy.. has allot of support.. and is still C.. just a bunch of little functions to make life easy.
[19:26:34] <atom1> can you use their stuff without their bootloader?
[19:26:55] <Connor> Yea. You just need to use the ISP to program in stead.. I do that too.
[19:27:17] <atom1> i've got my own programmer
[19:27:25] <Connor> As do I.
[19:27:44] <atom1> one of mine?
[19:27:49] <Connor> No.
[19:27:57] <Connor> Oh, that's right.. you designed one..
[19:28:05] <Connor> I'm using a Pololu one.
[19:28:09] <atom1> http://tom-itx.dyndns.org:81/~webpage/boards/USBTiny_Mkii/USBTiny_Mkii_index.php
[19:28:22] <atom1> covers all the 8bit protocols
[19:28:26] <atom1> not hvpp
[19:28:34] <atom1> isp, pdi and tpi
[19:29:04] <Connor> Be back in just a few.. re-mounting my controller board in the CNC.
[19:29:18] <atom1> i'm gonna go take a break for a while
