[14:55:02] <ries> Hey guys, I have two questions. I am making a indexer for my 2.dD CNC router (almost finnished) what software do you guys use to make the designs? Also, should I put LinuxCNC in Lathe mode or is it just a 4th axis? I guess it's not Lathe mode, because that's different from a indexer, right?

[15:22:24] <Einar> How do I set USC to use parport at 0xD800? I tried putting: loadrt hal_parport cfg="0xD800" in univstep_load.hal
[15:22:54] <Einar> But still get errors indicating it tries to use 0x378.
[15:23:16] <Einar> USC test program runs fine with D800.
[15:25:52] <awallin_> blah, there's no documentation for hal_parport here??
http://www.linuxcnc.org/docs/2.5/html/
[15:26:29] <awallin_> oh it's here..

[15:27:05] -!- archivist_herron has quit [Ping timeout: 245 seconds]
[15:29:37] <Einar> Blah?? I found that. And tried it, but as I wrote it still barfs at 378.
[15:30:05] <Einar> BTW: This is 2.6
[15:30:30] <archivist_> did you remember the 0x before the address
[15:30:55] <jdh> do you have any other hal files loading?
[15:31:06] <awallin_> can an unsigned short hold 0xd800 ?
[15:31:39] <jmasseo> that's a 16 bit value, i don't see why not.
[15:33:56] <Einar> Yes, I used 0xd800. Other .hal files are loaded, but no ref to 378 in them. Unless there are any loaded that are not mentioned in univstep.ini Unsigned int can hold up to 0xFFFF
[15:35:50] <jdh> does it use hal_parport, or hal_ppmc?
[15:36:46] <jdh> loadrt hal_ppmc port_addr=<addr1>
[15:38:56] <jdh> looks like the default USC hal file doesn't specify IO address so it defaults to 0x378. Change it like the above line.
[15:39:04] <Einar> There's a "loadrt hal_ppmc" in univstep_load.hal. I put my loadrt hal_parport cfg="0xD800" before that.
[15:39:21] <Einar> I'll do.
[15:39:31] <jdh> get rid of your line, change the existing one to specify addresss

[17:11:32] <Einar> I bought the USC before and was VERY pleased with the support. And how much is a Mesa with the necessary breakouts etc.?
[17:12:18] <Einar> And when the freight + customs + VAT is added the difference is not that great.
[17:12:50] <jdh> it's pretty hard to beat Mesa support for linuxcnc
[17:13:45] -!- toastydeath has quit [Ping timeout: 245 seconds]
[17:13:57] <jdh> $200us for a Mesa 5i25+breakout
[17:14:00] <Einar> I can't vote there as I did not try them. I might though, as it seems I am on my way into LinuxCNC and will need something for my Emco5 lathe too.
[17:14:27] <jdh> but, no plug in SSR slots, no on-board estop handling (could be a plus or minus I guess)
[17:15:00] <Einar> Ahh... Now my Dell is also booting after swapping CD drive with a DVD drive. Duhh!!
[17:15:15] <archivist_> Einar, ask skunkworks for an emco setup using nothing extra
[17:15:16] <jdh> you can evidently drive an Emco5 as-is with linuxcnc + pport
[17:15:54] <Einar> I may try that, as the PC I brought up before this had quite good latency numbers.
[17:17:13] <Einar> Oh. My Emco is now running modern stepmotors+drives, so will need faster steprates than the original.
[17:17:30] <Einar> Well, not need, but want. ;-)

[22:38:18] <PCW> someone blew up 4 7I77s and claimed it was our fault, we said we would
[22:38:19] <PCW> repair/replace them but needed them returned (they never returned them)
[22:39:41] <jp_mill_> ha. I must of had the same issue in the 7i33 and dealt with it thru input/output scale command voltage was inverse to encoder rotation
[22:40:16] <PCW> must have a driver or encoder with differernt wiring
[22:40:56] <jp_mill_> all the same hardware less just swapped out the 7i33 for a 7i77
[22:41:15] -!- sheppard has quit [Ping timeout: 245 seconds]
[22:42:33] <PCW> There may be a encoder or analog out differerence
[22:42:35] <PCW> 7I77 is actual volts (+10 is +10) 7I33 I think may be backwards
[22:43:33] <jp_mill_> that could explain it
[22:43:41] <PCW> I like to set the analog scale to machine units/second at +10V
[22:44:08] <PCW> (for a velocity mode drive)
[22:44:43] <jp_mill_> makes sense
[22:46:31] <PCW> It means:
[22:46:33] <PCW> 1. The PID output is in reasonable engineering units
[22:46:34] <PCW> 2. Setting for FF1 is known (~1)
[22:46:36] <PCW> 3. PID settings are the same for mm/inch machines
[22:48:07] <PCW> (no hidden scale factor in PID number)
[22:48:17] <PCW> numbers
[22:49:50] <jp_mill_> so 10V would be machine max velo
[22:50:20] <PCW> yeah
[22:52:10] -!- somenewguy [somenewguy!~somenewgu@pool-108-7-96-203.bstnma.fios.verizon.net] has joined #linuxcnc
[22:53:54] <jp_mill_> PCW: how would you go about tuning torque mode?
[22:54:57] <PCW> Not sure if it the bast way but I see how high I can set the D term first
[22:55:03] <PCW> best
[22:55:49] <PCW> YOu may also need to run a faster than 1KHz servo thread fotr torque mode drives
[22:56:42] <PCW> since linuxcnc is closing the (higher bandwidth) velocity loop
[23:00:30] <jp_mill_> ok seems to be working good right now. @ 3Khz . although my heidihain DRO says my X axis is moving .107 when lcnc says .100"
[23:00:59] <somenewguy> bigger the move the smaller teh measurement error, if you are in the middle of calibration
[23:01:06] <jp_mill_> going to have to break out the dial gauge
[23:01:54] <jp_mill_> .007 is pretty big error for a heidinhain scale
[23:02:23] <jp_mill_> i would not think it's that wrong
[23:03:31] <jp_mill_> i know it's not backlash screws are new and the movements on the scale are repeatable
[23:07:23] <jp_mill_> hmm. dial gauge agrees with the scale?
[23:08:07] <PCW> losing.gaining counts or scaling maybe
[23:09:53] <jp_mill_> one direction seems to gain other it looses weird. but very repeatable. just doing .100" increments
[23:14:11] <PCW> rotary encoders on motors?
[23:14:17] <jp_mill_> yes
[23:14:30] <PCW> differntial outputs?
[23:14:33] <jp_mill_> teco servos and amps
[23:14:35] <jp_mill_> yes
[23:15:30] <jp_mill_> both x and y axis are behaving the same
[23:15:33] <PCW> 7i77 jumpered for differential (3 jumpers per encoder)?
[23:16:11] <jp_mill_> yes but i shall double check
[23:17:04] <jp_mill_> all jumpers are away from the db25
[23:18:23] <PCW> that shoud be correct
[23:18:36] <PCW> 5V at 7I77 OK?
[23:19:42] <jp_mill_> led's say so
[23:19:56] <jp_mill_> and the dro in axis is spot on every time
[23:20:21] <jp_mill_> if i ask for .100 it moves .100 on the axis dro
[23:20:42] <PCW> do you have a separate 5V supply (the 7I77 is usually marginla with cable power)
[23:21:00] <PCW> (depending on encoder draw)
[23:21:01] <jp_mill_> yeah i will rig one up and check
[23:21:15] <PCW> I would check the 7I77 5V
[23:21:23] <jp_mill_> ok
[23:21:36] <jp_mill_> first i have to go pick up my son
[23:21:42] <jp_mill_> Thanks for the help
[23:21:47] <PCW> and if its low, re-jumper both 5I25 and 7I77 for no cable power
[23:22:02] <PCW> and power 7I77 at 7I77
[23:22:13] <jp_mill_> ok
[23:22:27] <jp_mill_> in other words dont blow up the 5i25
[23:22:30] <PCW> rejumper is important (you dont want your external 5V to power the PC)
[23:23:04] <PCW> there is a way (mismatched jumpers)
[23:23:36] <jp_mill_> yeah that would suck
[23:24:40] <PCW> cable power grounded at 5I25 and external (no current limit) 5V on 7I77 jumpered for cable power
[23:24:44] <jp_mill_> if i do that would i have to use an external 5V on a 7i73 or wuld the cat5 be good enough considering the 7i77 is feeding it off of a larger supply?
[23:24:59] <PCW> 7I73 is fine off cat5
[23:25:10] <jp_mill_> cool
[23:25:13] <jp_mill_> thanks
[23:25:22] <PCW> (it needs 3.3 only and has LDO and ~80 ma)
[23:28:16] <somenewguy> does anyone know of a good test cut pattern to check the lash and overall well behavedness of a new-to-me mill?
[23:28:33] <somenewguy> or do I need to code my own spiral inside a hatch pattern that in my head will do a good job of showing me whats up
[23:29:23] <somenewguy> its a mini mill so I am thinking a 3 inch square of lexan and one of my tiny pyramid bits
[23:44:02] -!- stsydow has quit [Quit: Leaving]
[23:50:08] <jdh> I'd start with a line, then a square.
[23:53:51] <somenewguy> currently I have done some simple measuring, I have a lot of measuring tools since I build engines, and I seem to have <.002 backlash on all axis
[23:54:20] <somenewguy> but that is with no load, so i figured milling some thing soft really fast so that the inertia of the machine will reveal any slop, but not so fast as to loose steps, and it should be nice and informative
[23:55:26] <somenewguy> I ahve already cut a few simple objects and it is pretty well behaved, just want to get a solid idea on some junk material before I ahve a big job get ruined by an obvious lack of adjustment
