[00:02:54] <Jymmm> JT_Shop: Next time... PUT THE SEAT DOWN!!!
[00:11:15] -!- visinica has quit [Quit: Leaving]
[00:11:58] <MacGalempsy> anyone got a moment to look at that link I posted earlier to maybe give some motor tuning advice?
[00:24:10] -!- tmcw has quit [Ping timeout: 245 seconds]
[00:24:33] <andypugh> Try some D
[00:26:03] <andypugh> But a very small amount. You are looking at micro-inches per ms, so start with a very small mumber.
[00:26:52] <andypugh> Like, start at .000001 then 0.00001 and watch how it goes.
[00:27:12] <MacGalempsy> that is to kill the initial spike, right?
[00:27:30] <andypugh> it's to damp the whole response
[00:28:29] <andypugh> If it makes things worse, try a negative number, then I will try to remember what misconfiguration meant that I needed that :-)
[00:29:23] <andypugh> It is instructional to play with a bare motor with only D-gain.
[00:29:27] <MacGalempsy> andypugh: have you had any luck with the autotune PID?
[00:30:09] <andypugh> I have never tried it, but I have the impression that it only ever worked for the guy who submitted it. I might be wrong.
[00:30:12] -!- geografa has quit [Quit: Computer has gone to sleep.]
[00:30:23] <MacGalempsy> hah. ok
[00:30:29] <andypugh> It's a great idea.
[00:32:13] <andypugh> I tune loops for a job, but nasty ones where the normal tools don't work.
[00:33:12] <andypugh> I have been working on this oil pump controller for 18 months.
[00:33:17] <MacGalempsy> cool. I tuned the PID on my heated bed on the cnc gluegun, but this takes the cake. the ferror seemed to get better
[00:33:25] <MacGalempsy> oh, dang.
[00:34:18] <MacGalempsy> need to figure out how to export the PID data from halscope because there are a few free PID tuning softwares that could help
[00:34:37] <andypugh> My P gain is the product of two 16x16 maps, the D gain the same. The Igain is the product of 3 maps. I am not sure that this enough to cover the complexity of the system response.
[00:34:41] -!- PetefromTn [[email protected]] has joined #linuxcnc
[00:36:48] <andypugh> So, in theory, I have 192 P numbes, 192 D numbers and 288 I numbers to get right. In practice I flat-map a lot of it.
[00:40:08] <andypugh> But given that I control a valve that controls the flow of oil that goes into a spring-loaded chamber that controls the stroke of a pump that pumps the oil that I started with, and the viscosity and hence pressure and flow of the oil are a strong function of tempreature and pressure, it is not a problem ameanable to analysis (especially as large areas of the parameter space are off limits as they destroy the engine)
[00:40:37] -!- patricka_ has quit [Ping timeout: 248 seconds]
[00:42:44] <andypugh> If you decide that your system response is very non-linear you do have the option of making your P, I or D gains dependent on other system parameters, I created the lincurve HAL component specifically for that scenario. But it makes life a lot easier if you stick with 3 numbers.
[00:44:15] <MacGalempsy> andypugh: do you know if it is possible to make the 7i77 put put more than 10V for the TACH signals?
[00:45:07] <andypugh> I don't think that they can. In fact i don't know where they get 10V from.
[00:45:33] -!- kwallace_shop1 [[email protected]] has parted #linuxcnc
[00:45:53] <MacGalempsy> ha. yeah 10v for the drive signal
[00:46:21] <andypugh> You might be able to do something clever with an Op-Amp. Or ou might be better being clever still and describing the problem to PCW
[00:46:40] <MacGalempsy> 60inches per minute should be plenty
[00:47:31] <andypugh> Sounds a bit slow, but you don't spend that much time in rapids. It's a fast cut.
[00:47:36] <MacGalempsy> we chatted this afternoon a little. the only thing I could think of was sending the ref at a lower voltage, say 5v and let the tach send 10
[00:48:09] <MacGalempsy> the main goal is to get it all running and finetune the speed later
[00:49:00] <MacGalempsy> the thought bipassing the tach loop would induce a lot of error, but from that chart you looked at, you could see the following error is pretty low at 8in/min
[00:49:30] <MacGalempsy> figured that would be nice for a finishing cut
[00:53:11] <andypugh> I am not a perfectionist. If I was you I would be making partd
[00:53:18] <andypugh> (err, parts)

[00:56:09] <andypugh> (I do actually have a larger, preloaded, leadscrew, I am just not sure I can make it fit)
[00:56:44] <Jymmm> Hey andypugh
[00:57:36] <MacGalempsy> you couldnt tune that out?
[00:58:27] <andypugh> I am pretty sure it is mechanical.
[00:59:16] <andypugh> I might actually mount an eccentric in the head and deliberately wobble the table to work out what moves relative to what

[01:13:03] <PCW> MacGalempsy: if you want to use free 7I77 channels for Tachometer simulation you will need to set the drives
[01:13:04] <PCW> tachometer input gain to be the same (10V full scale) as the reference input. Pretty sure this is set via a resistor
[01:13:06] <PCW> on that plug in module (If your drive is like the PDF)
[01:13:44] <MacGalempsy> it is like the one on the PDF
[01:14:25] <MacGalempsy> the guy on the phone said the only reason the number is different is because of the custom order, which had some special resistors done
[01:15:21] <MacGalempsy> not that the resistors themselves are special, but they did tuning with the reisitors
[01:19:21] <MacGalempsy> kkhttp://www.flickr.com/photos/58181938@N03/10933060086/
[01:19:34] <andypugh> One of these with CNC would be fun:
http://www.lathes.co.uk/rindis/index.html
[01:19:36] <MacGalempsy> sorry
[01:20:07] <MacGalempsy> simple and sweet
[01:21:18] <PCW> Though as Andy said you might just try some D term (It really should be identical to feeding the velocity into the tach input)
[01:21:54] <PCW> A higher sample rate may be need to get as much D term as you want
[01:22:01] <PCW> needed
[01:22:44] <MacGalempsy> ok. the wife is doing laundry at the moment, so I'll have to take my turn on the electricity
[01:23:22] <MacGalempsy> PCW: earlier, you thought the error may be higher without the tach signal. do you think it could get much better than .0004?
[01:23:46] <PCW> Do you have any D?
[01:23:51] <MacGalempsy> not at the moment
[01:23:57] <MacGalempsy> only P, FF1 and FF2
[01:24:14] <andypugh> Can you measure .0004?
[01:24:14] <MacGalempsy> was going through John's tuning tutorial
[01:24:20] <PCW> Well with no Tach feedback D will be needed
[01:24:33] <MacGalempsy> the encoder resolution is .0002
[01:24:43] <MacGalempsy> well, encoder and ballscrew
[01:25:00] <andypugh> Yes, but my Calipers are .0005
[01:25:44] <PCW> what ballscrew pitch, gearing, and encoder counts?
[01:25:53] <andypugh> If this is a lathe, then I would want 10x better, and be using micrometers.
[01:26:10] <MacGalempsy> oops. it is .00002, so I should try to do the feedback thing
[01:26:40] <PCW> Yeah I thought it would be higher
[01:26:43] <MacGalempsy> 5 turns per inch, 2500c/t encoder, and no gear reducer
[01:27:12] <PCW> yeah so 50000 counts/inch
[01:27:15] <MacGalempsy> any thoughts on HAL code?
[01:27:30] <andypugh> For fun, work out how much your machine moves in a cold draught.
[01:27:31] <MacGalempsy> or known example to make this work?
[01:28:18] <MacGalempsy> when I turned it on this morning cold, it had a hard time with my PID values. how long do these things need to warm up before it can be considered steady state?
[01:28:47] <andypugh> Until the remperatures stop chanigng
[01:28:53] <PCW> I would just try D first (since on your drive, the tach input and reference input are just summed this can just as well be done in the PID comp)
[01:29:13] <MacGalempsy> ok. I will try that and see what happens
[01:29:45] <andypugh> That's the best plan. It might help, or you might be near to machine limits.
[01:30:19] <PCW> pump up D until its too buzzy to stand and then back off till its livable
[01:31:23] <PCW> (you can get more at a higher sample rate)
[01:31:24] <PCW> then you should be able to increase P
[01:31:30] <MacGalempsy> the other night, I had it up to 2340 and it was doing well, but the next day, I could barely get 1800 until it was 100% hot
[01:32:00] <andypugh> (and possibly experiment with negative D, if that helps I will be forced to remind myself what misconfiguration made that useful)
[01:32:01] <PCW> Not enough (or any) D
[01:32:04] <MacGalempsy> with the 2340 the table buzzed
[01:33:10] <andypugh> Yes. As the machine warms up it will get more responsive (mainly oil friction).
[01:33:12] <MacGalempsy> maybe it would be good to put together a warmup program to run the machine around a while after first turning it on
[01:33:43] <MacGalempsy> so should I warm it up 100% then do the PID tuning?
[01:33:45] <andypugh> But you may be able to get more P with a hint of D
[01:35:17] <PCW> I think its likely now that theres no D (either from external feedback or the PID)
[01:35:18] <PCW> which will rather severley limit P
[01:36:16] <andypugh> I would say tune for the cold machine. Though this will depend on the work you are doing. Really high accuracy work is done in temperature-controlled roooms, and they use ballscrews and slides with coolant channels running at controlled temperatures.
[01:37:08] <MacGalempsy> no coolant lines here
[01:37:50] <MacGalempsy> was hoping to have the stand done by now, but my uncle went on vacation. the nerve, right?
[01:40:09] -!- PetefromTn has quit [Remote host closed the connection]
[01:44:04] <andypugh> It is possible to make the PID terms temperature dependent, but it adds a lot of compelxity.
[01:44:31] <andypugh> Anyway, time to sleep
[01:44:40] -!- andypugh has quit [Quit: andypugh]
[01:45:19] <MacGalempsy> going to work on D

[10:45:10] <MattyMatt> they're about the same price as the common chinese ones, but the chinese ones are common - which improves servicability IMO
[10:47:44] <archivist> while those drives look good the auction seller lacks credibility
[10:48:09] <archivist> claims new but they are filthy
[10:49:35] <MattyMatt> Q2: if the mitsu ones have analog input, which input would be best to use, considering I'd need to buy a mesa card either way?
[10:49:41] <MattyMatt> yeah they dusty
[10:49:56] <MattyMatt> but that could be 10 minutes in a woodwork shop
[10:50:00] <archivist> you can download the manual
[10:50:30] <archivist> is the auction for 1 or 5 off
[10:50:46] <MattyMatt> buy it now, 1 off
[10:51:38] <archivist> the pictures show more than one
[10:51:55] <MattyMatt> yep, which is why I'm sharing the link :)
[10:51:56] <archivist> that is one lazy seller
[10:52:58] <MattyMatt> I can't really afford one tbh. I have a 500W palm router to use up first
[10:55:26] <archivist> I need two of them but have no cash
[10:56:46] <archivist> cannot find a report item category to whine at ebay , it almost seems a bad listing is acceptable policy
[10:57:19] <MattyMatt> caveat emptor. bad listings lower the price IME
[10:57:57] <MattyMatt> I got some lovely ballscrews that were described as travelling struts
[10:59:12] <MattyMatt> MOD nomenclature
[10:59:18] -!- patrickarlt has quit [Ping timeout: 245 seconds]
[11:00:39] <MattyMatt> asking questions to the vendor helps them improve the listing, I find, but that just helps the competition if it's a bidding war :)
[11:02:16] <archivist> I just found a valid whine so sent that, misleading title
[11:03:40] <archivist> his having a date in his name and a score of 0 tells me he is a regular bad seller :)
[11:04:11] <MattyMatt> or a genuine noob
[11:04:37] <MattyMatt> not saying 1 off 5 available is a noob mistake
[11:05:57] <archivist> dont think he is a noob, an honest user would never tick new for those dusty items
[11:06:28] <MattyMatt> a proper crook woulda dusted them off, with Mr Sheen
[11:09:43] <MattyMatt> I use a soft 3" paintbrush to dust electronics

[11:10:36] <archivist> brush and vacuum cleaner...ex TV engineer :)
[11:12:46] <RyanS> Is a BF20 size mill at all useful as a glorified drill press and stock square upperer... I'm still procrastinating about CNC

[11:18:10] -!- FreezingCold has quit [Read error: Operation timed out]
[11:18:15] <MattyMatt> my time is cheap :)
[11:20:00] <MattyMatt> I don't have any real experience, but I'd imagine a horizontal mill or surface grinder are the best for squaring stock
[11:20:38] <MattyMatt> with a good heavy bed, and basic power feed
[11:22:00] <RyanS> I had thought about it , however, because of my disability I hire help , so I don't want to use up that time doing the conversion. Although the price is making me cringe
[11:24:15] -!- phantoneD [[email protected]] has joined #linuxcnc
[11:24:38] <MattyMatt> I got a knee mill base, and I've only used it manually with a horizontal dremel so far. I might keep it manual it's handy
[11:26:08] <RyanS> I suppose I intend on designing everything in CAD and hopefully eliminate or at least minimise things like old school dye and layout

[11:32:16] <MattyMatt> time is the most liquid asset, and the scarcest resource
[11:34:27] <MattyMatt> you could put a decent x/y table on a cheap drill press, for drilling

[11:35:12] <RyanS> I have one on benchtop drill press. That's why I want to upgrade to a pedestal

[12:35:41] <jthornton> well, you won't use stepconf if your using anything else but the parallel port
[12:35:55] <kengu> yeah but just to figure out where the setting is
[12:36:13] <jthornton> pncconf is for Mesa cards and is a totally different than stepconf

[12:36:47] <kengu> yeah. but I did find the setting now from pncconf after spying from stepconf
[12:37:30] <kengu> there is this "limits/home shared" input category in pncconf that I for some reason had not seen before

[13:50:14] <MacGalempsy> why cany it just ground?
[13:50:38] <jdh> because it is a sourcing output?
[13:51:33] <jdh> perhaps a pull-down on the drive reset line and have the output on to keep it high
[13:53:18] <MacGalempsy> is that something radioshack might have?
[13:53:49] <jdh> a resistor? or the relay? They will have both.
[13:54:08] <MacGalempsy> I have one more set of 4 relays
[13:54:31] <jdh> might wait for pcw to show up for a more definitive answer.

[15:16:25] <pcw_home> most likely there is a number in the mode setting string thats not legal for the 7I84
[15:20:11] <pcw_home> in your setup sserial_port_0=123xxx

[16:17:11] <MacGalempsy> trying to understand what each position in the address means?
[16:17:20] <pcw_home> that cannot possibly work
[16:17:45] <MacGalempsy> I want to run mode 3 on the 7i77 and mode 0 on the 7i84
[16:18:06] <pcw_home> as the manual says they are channels numbers in left to right order
[16:18:47] <MacGalempsy> but there are no practical examples
[16:18:50] <pcw_home> on a standar 7I77 config 7I77 channel 0 is Field I/O, 1 is anlog out and 2 is the expansion port
[16:20:23] <MacGalempsy> so 000xxx should work, right?
[16:20:32] <MacGalempsy> of 300xxx?
[16:20:39] <pcw_home> sserial_port_0=000xxx should work
[16:23:27] <MacGalempsy> ah, that worked. thanks a bunch!
[16:24:17] <MacGalempsy> this whole process is quite humbling. i have a research degree, but the learning curve is so high.
[16:24:21] <pcw_home> if you look at the 7I77 and 7I84 manuals they list the legal modes

[16:58:34] <JT_Shop> ok, so it is firmware dependent?
[17:00:35] <pcw_home> Yes, because the order of sserial ports can change but all 7I77 configs (with a 7i77 on P3)are the same
[17:01:39] <JT_Shop> ok thanks

[21:37:20] <maZer> until index
[21:38:09] -!- bedah [[email protected]] has joined #linuxcnc
[21:38:13] <andypugh> OK, the you need the latch to be the opposite sign. You also need HOME_USE_INDEX in the INI and to have net-ed index-enable in the hal.
[21:38:54] <maZer> ok big thanks
[21:41:24] <maZer> andypugh i did home_search_vel -5.0 and home_latch_vel 0.5
[21:41:48] <maZer> and the machine drivers over the limit switch and drives forward to emergency stop :(
[21:42:15] <maZer> did i done something wrong in the hal with min-home-x ?
[21:42:29] <maZer> Also i use the min-home-x switch for this
[21:42:45] <andypugh> maybe. min-home-x isn't anything LinuxCNC knows anything about.
[21:43:13] <andypugh> That is a signal name, and has no special meaning

[22:45:50] <JesusAlos> must configure voltage and speed in bios?
[22:46:43] <JesusAlos> why detect PCI card but not like parport?
[22:47:54] <ju-emb> because the paraports on that cards doesn't show up like real parports, uou need a driver for that
[22:50:01] <ju-emb> some where in the docu I read that you have to load some other driver before the parport
[22:50:31] <ju-emb> I talk about lcnc hal documentation
[22:53:58] <andypugh> A PCI card should be a "real" parport
[22:54:58] <kwallace2> What about dmesg?
[22:54:59] <andypugh> I wonder why is is claiming to be a Serial controller?
[22:55:06] <ju-emb> after you loaded the driver yes, but before that she doesn't have an defined I/O Address
[22:56:01] <andypugh> Anyway, if that is the card, I think you need to try io addresses e100 and e000
[22:56:10] <ju-emb> sorry I/O she has, but no memory location like a parport
[22:56:30] <andypugh> 1c00 is the PCI address, not the IO port.
[22:57:57] -!- toner has quit [Ping timeout: 272 seconds]
[22:58:38] <JesusAlos> The PCI-E card have one LPT port and two RS232 ports
[22:59:02] <JesusAlos> I think the directions is 1c00,e000 and e100 respectivy
[22:59:02] <kwallace2> I think it is a single serial port card with a DB25 connector.
[22:59:04] <JesusAlos> no?
[22:59:37] <andypugh> In the proc/ioports listing earlier you can see that the r8169 ethernet port has an address listed as d000 in the same format as the prport has 0378.
[23:00:14] <ju-emb> did we try dmesg | grep parport

[23:03:10] <JesusAlos> yes, onboard
[23:03:21] <ju-emb> yes, so your PCI-e is not recognized
[23:03:31] <andypugh> Have you tried e100 and e000 with the parport tester?
[23:03:43] <JesusAlos> go now
[23:04:01] <JesusAlos> go to try
[23:05:05] <kwallace2> Just look at the traces on the DB25. If it looks like close to half the pins go to ground, it is a parallel port, otherwise it is a serial port.

[23:24:57] <ju-emb> do you mean there is only the header connector on the MoBo
[23:25:36] <JesusAlos> yes
[23:26:13] <ju-emb> Do you start that MoBo with EFI ?
[23:27:19] <JesusAlos> EFI? in bios configurationsay?

[23:31:02] <ju-emb> That MoBo has two modes to boot it.
[23:31:04] <ju-emb> one is BIOS other is UEFI
[23:31:06] <ju-emb> You have to start it in BIOS Mode to run Linuxcnc,
[23:31:08] <ju-emb> but there are some special features in such boards that needs to be activated in order to get the real BIOS behavior

[23:40:31] <ju-emb> sure because you doesn't have your harddisk configured for that,
[23:40:33] <ju-emb> but there are still some points in the bios you need to activate to make your board work in real bios mode
[23:41:12] <andypugh> JesusAlos: A 6i25 will fit nicely in that slot...
[23:41:33] <JesusAlos> from mesa?

[23:53:41] <maZer> hi all :)
[23:55:49] <maZer> i have a last problem with the homing. My machine is moving to the limit switch and waiting until the limit switch is released. Is there a way to disable that? Also that the machine is not overshooting the limit switch?`
