[00:02:49] <andypugh> Yes, HAL has a scale component, but that should not be necessary.

[00:11:53] <PCW> umm normally those would be you full speed spindle RPM
[00:12:36] <Mark___> so it should be 6000
[00:13:03] <PCW> is that full spindle speed when you have a 10V analog command?
[00:13:11] <Mark___> yes
[00:13:34] <PCW> is the spindle reversable?
[00:13:43] <Mark___> yes
[00:14:39] <PCW> so the scalemax and maxlim parameters should be 6000 and minlim -6000
[00:14:52] <Mark___> ok
[00:15:16] <andypugh> Can the VFD accept negative voltage as reverse? (the 7i77 can do that, though not all VFDs can)
[00:15:17] <PCW> BTW analog out 5 is suggested for spindles (since it has its own enable)
[00:16:01] <Mark___> no vfd its a servo motor under a driver control
[00:16:54] <Mark___> Hi pete
[00:17:03] <PCW> Hi
[00:17:29] -!- archivist_herron [archivist_herron!~herron@herronwindows.co.uk] has joined #linuxcnc
[00:18:45] <PCW> This is not really VFD/servo related just that channel 5 has an independent enable which normally the spindle needs
[00:18:59] <Mark___> we were just trying tgo work out the spindle orient and my spindle went out of whack as far as rpm
[00:19:27] <PCW> (all the motion axis (0..4) have a common enable)
[00:19:27] -!- sumpfralle [sumpfralle!~lars@on1.informatik.uni-rostock.de] has joined #linuxcnc
[00:19:59] <Mark___> ok I can change it around tommorow
[00:21:01] <andypugh> PCW: We are looking at spindle orientation, the HAL looks a bit like this now
http://pastebin.com/Hw8DmBED
[00:22:17] <andypugh> The thing I can’t explain is that the spindle speed was OK, then I messed about with his HAL, and now it is broken, despite the same values being passed through outside of toolchange
[00:23:12] <PCW> The scalemax was 10 which means it could not have worked before without some external scaling
[00:24:25] <PCW> not this problem but the encoder scale is unlikely to be 4098 (probably should be 4096)
[00:25:31] -!- sumpfralle has quit [Ping timeout: 258 seconds]
[00:25:44] <Mark___> http://pastebin.com/BhMVgqVx
[00:25:52] <Mark___> newest hal for now
[00:28:46] <PCW> in IN file:
[00:28:48] <PCW> [SPINDLE_9]OUTPUT_SCALE should be 6000
[00:28:49] <PCW> [SPINDLE_9]OUTPUT_MIN_LIMIT should be 6000
[00:28:51] <PCW> [SPINDLE_9]OUTPUT_MAX_LIMIT should be -6000
[00:28:52] <PCW>
[00:29:06] <PCW> and the 4098 should be fixed
[00:29:54] <andypugh> yes, that is just another of my horrible errors and might well explain the random alignment
[00:31:53] <Mark___> Ok spindle is ok again
[00:33:27] <andypugh> It’s a bit strange that it worked before.
[00:33:48] <Mark___> anyway to but an m19 for spindle orient instead of a tool call up
[00:33:52] -!- asdfasd has quit [Ping timeout: 240 seconds]
[00:34:08] <andypugh> M19 will have to wait, I am afraid
[00:34:19] <andypugh> It’s far too late here
[00:34:50] <Mark___> and the spindle orients correctly :)
[00:34:51] <Mark___> :)
[00:34:53] <Mark___> :)
[00:34:58] <andypugh> Aha!
[00:35:34] <andypugh> Now, there is a slight wrinke here, the spindle won’t actually orient correctly until it sees the index
[00:35:54] <Mark___> I just have to learn how to tune the servo's so it stays put for a bit then all will be ok
[00:36:21] <andypugh> We probably need to find a way to home the spindle at the same time as the axes
[00:36:57] <Mark___> If I get the m19 working I could use a little homing program
[00:37:11] <Mark___> G91 G28 Z0
[00:37:14] <Mark___> X0 Y0
[00:37:20] <Mark___> S200 M3
[00:37:23] <Mark___> M19
[00:37:25] <Mark___> M30
[00:37:48] <andypugh> A crude way would be to net pid.spindle.ff0 to halui.0.axis-is-homing :-) (very crude)
[00:37:56] <Mark___> OR ADD A M5 AFTER THE SPEED COMMAND

[01:00:52] <PetefromTn_> Thats odd..
[01:01:07] <PetefromTn_> just running some code to mill some small pockets in this plate.
[01:01:42] <PetefromTn_> it ran the first pocket fine and then moved to the second pocket, dropped down into it and then returned to Z height.. Here is a paste of the code...

[01:04:35] <PetefromTn_> it is like it just dismissed the finish pass around the inside of the hole without moving it and just went back up to Z height. Any idea why it would do that?

[01:27:43] <PetefromTn_> actually I thought I figured it out but apparently I was mistaken.
[01:28:08] <PetefromTn_> Not sure why it does not run the circular path inside the hole at z-.25
[01:28:16] <PetefromTn_> the second one...
[01:28:52] <PetefromTn_> it works in simulation but not on the machine.
[01:29:40] -!- ries has quit [Quit: ries]
[01:29:44] <andypugh> Line 1 has no idea if it is G1 or G0, or the feed rate, so that will be a bit random (but not the problem)
[01:30:24] <PetefromTn_> this is a cut from the end of the program so all that comes before this.
[01:33:23] <andypugh> Line 6? You don’t return to initial X so the second circle has zero radius (guess)
[01:34:35] <PetefromTn_> yeah but it goes to it on the circular interp line before it makes the curve no?
[01:35:05] <PetefromTn_> whats wierd is it worked the first time in the early lines but not the second position...
[01:36:26] <PetefromTn_> I think you may be onto something. I am gonna insert the X position and try again....
[01:36:29] <PetefromTn_> BRB
[01:36:48] <andypugh> my guess would be that the starting XY position at line 3 is not the same as at line 9. (because of line 4)
[01:40:12] <PetefromTn_> I just editied the program to have the X and Y position like the first hole and saved and reopened it in LinuxCNC. Running now...
[01:43:43] -!- syyl has quit [Ping timeout: 258 seconds]
[01:44:18] <PetefromTn_> well that sucks... it did the exact same thing. Just went down into the second hole and then went back up without running the circle interp...
[01:45:52] <andypugh> That’s just strange
[01:45:58] <PetefromTn_> yeah I know right...
[01:47:17] <andypugh> It isn’t your G90.1 mode? (I don’t think it cab be, actually)
[01:47:42] <PetefromTn_> I really need to fix this because I have to interpolate these holes for a press fit pin..
[01:48:52] <andypugh> Well, I am baffled. if you start at the same XY and run the same G2 then you should see the same circle.
[01:49:41] <andypugh> Given that we would have niticed this :-) What is different between the two G2s?
[01:51:22] <pcw_home_> sign of Y
[01:52:55] <andypugh> Good spot, pcw, It really is as late as I thought here
[01:53:02] <PetefromTn_> http://pastebin.com/QMug8bX5 Heres the whole program... I did edit the end to remove the G91 but that happens after this hole and spindle off etc...
[01:54:10] <PetefromTn_> it has to be a minus 1 because it is a different hole location no?
[01:54:36] <andypugh> I thought it was the same hole?
[01:55:12] <PetefromTn_> no man there are two holes... The program roughs out the two holes and then runs a finish pass into the two holes
[01:55:57] <andypugh> The code you have shown only has 2 x G2 so only 2 circles
[01:56:42] <PetefromTn_> yeah the first pastebin is just the finish passes on the two holes.... one at y pos and one at y neg of the same X position
[01:58:41] <andypugh> I would love to help sort this out, but it is 0300 and I have to be at work in 6 hours. I am fine with that now, but it will become increasingly impossible, so I am bowing out now.

[09:50:34] <Jymmm> Uh, dont dismiss it so easily. Do your research now that you have an idea. What you have may be a variant, or been replaced with something newer.
[09:51:51] <varesa> Jymmm: yeah I'm looking at various similar-ish connectors right now
[09:55:28] <varesa> I was thinking I could replace the big controller which now only serves as a power switch with a smaller switch box
[09:56:18] <varesa> If I could find the panel connector I wouldn't have to rip out all the wiring going to that inside the controller or cut the cable

[15:29:49] <Jymmm> great*
[15:30:06] <Tom_itx> any particular brand?
[15:30:14] <Tom_itx> on the low end side
[15:30:55] <Jymmm> Not really, every placed I used one it was different
[15:31:31] <Jymmm> you can also score with them too
[15:31:57] <Tom_itx> how do they set up for different folds?
[15:32:05] <Tom_itx> mechanically?
[15:32:26] <Jymmm> yeah, you just move the guards
[15:33:34] <Tom_itx> i wonder if used flebay would be wore out..
[15:34:00] <Jymmm> as long as you can get parts for it, you should be ok
[15:34:35] <Jymmm> why are you getting one?
[15:34:43] <Tom_itx> i'm not sure i am
[15:34:47] <Tom_itx> just looking
[15:34:55] <Jymmm> why do you want one?
[15:35:00] <Tom_itx> i've used one in the past
[15:35:04] <Tom_itx> to fold paper?
[15:35:37] <Jymmm> Are you printing instructions for stuff you sell?
[15:35:44] <Tom_itx> no
[15:35:57] <Tom_itx> unrelated venture
[15:36:08] <Jymmm> ah
[15:36:45] <Jymmm> if it periodic, might be chea[er to have a place do it for you
[15:37:04] <Tom_itx> it's for a non profit
[15:37:21] <Jymmm> non profit, not no profit =)
[15:37:32] <Tom_itx> rely heavily on donations
[15:37:41] <Jymmm> oh for them to use you mean?

[15:38:20] <Jymmm> gotcha, fold the givw use money please pamthilts ;)
[15:38:57] <Tom_itx> last one i used didn't work worth crap
[15:39:02] <Tom_itx> but it was pretty old
[15:39:15] <Jymmm> how so?
[15:39:26] <Tom_itx> like 1/2" off the mark?
[15:39:38] <Jymmm> that's the setup
[15:39:48] <Tom_itx> no the rollers were shot
[15:40:04] <Jymmm> Yeah, that's why I said able to get spare parts
[15:41:12] <Jymmm> Some are really slick and have three trays. and can fold on both axis =)
[15:41:17] <archivist> sand the rollers and clean with alcohol
[15:42:11] <Jymmm> archivist: these aren't hard rubber rollers, they're pretty soft actually
[15:42:34] <archivist> they get a hard coat that stops grip
[15:42:34] <Jymmm> the scoring wheel has hard rubber on it
[15:43:05] <Jymmm> archivist: Yeah, I have some Rubber Rejivinator for that

[15:47:26] <PetefromTn_> I did get the second pair machined last night and working on the third pair this morning. Should be all done with the first side of the parts by then. This afternoon I need to make the fixtures to run the second side and then I will be finished.
[15:48:22] <Tom_itx> did you make spares for setting up the 2nd op?
[15:48:31] * Tom_itx just has a feeling...
[15:49:23] <PetefromTn_> Unfortunately no I am limited to the stock on hand here. These parts are quite large for my machine actually. One is just inside the travel limits...

[17:01:40] <Loetmichel> but german BSI points out that the chamber has to be locked at all times when not in use. because the measurement curves are a secret
[17:01:59] <Loetmichel> DaViruz: not with about 200kg ferrite plates all around ;-)
[17:02:21] <Loetmichel> that would counteract the pourpose of the chamner if a signal can get in or out ;-)
[17:02:31] <DaViruz> maybe some kind of sonic data transfer is required
[17:02:50] <Loetmichel> http://cordsen.com/index.php/services/tempest-certification <- chamber
[17:02:58] <DaViruz> but i'm guessing the shielding is pretty much sound proof too
[17:03:10] <Loetmichel> it isnt

[17:04:39] <PetefromTn_> Okay that is fine.
[17:04:47] <ssi> I dunno
[17:04:51] <PetefromTn_> I don't have a big Shangri la house here
[17:04:56] <ssi> I have the bearings and shims
[17:05:08] <ssi> I'm gonna bring the whole head if I can; it's in pieces, so I hope I get everything

[17:40:49] <Jymmm> Is there such a thing as a "closed system" steam engine?
[17:41:18] <Jymmm> or boiler system
[17:42:07] <Connor> http://en.wikipedia.org/wiki/Condensing_steam_locomotive
[17:42:17] <Jymmm> Basically turn a motor when heat is applied when you don't have water to spare.
[17:43:13] <Connor> you would just run the exhaust steam to a condenser.
[17:43:38] <Jymmm> ok, so you just need to drop the water temp back down?
[17:44:27] <Connor> Looks like it..
[17:45:38] <Jymmm> Hmmm, I wonder how small I could make the entire system

[17:47:02] <Jymmm> I want to make a generator (of sorts) than can be put near a camp fire at night and charge up batteries and provide lighting.
[17:47:57] <Jymmm> I figure even coals are still hot enough to last 8+ hours, which should be long enough to recharge ay set of battereis.
[17:48:05] <Jymmm> any*
[17:49:08] <Connor> Make yourself a wood gasifier
[17:49:27] <Connor> Then you can use any standard gas generator / engine.
[17:49:34] <Jymmm> I dont want to use a tcooler if that was your thinking
