[00:01:34] <JT-Shop> do you have the cables ready to ship that go between the 5i25 and the 7i67
[00:02:15] <PCW> Yep ts just a IEEE-1284 M-M cable we have 6 and 10 Ft
[00:02:19] <andypugh> PCW: I don't know exactly what was wrong with that arithmetic, but rounding to the nearest 360 on a 0-1 signal is clearly daft. And it meant that I couldn't configure my motors to start in both directions.
[00:03:08] <PCW> I probably only started in the good direction
[00:03:39] <JT-Shop> I'll call tomorrow and order a set... I'm working on an upgrade for the plasma using a 525
[00:03:51] <andypugh> I can still get them running way too fast and not stop, but I think that is due to them skipping phases in some way, and that is endemic to three phase motors with a relatively slow control loop
[00:04:42] <JT-Shop> that makes a neat package with that cable
[00:04:57] * JT-Shop goes to fire up some chow
[00:05:40] <PCW> JT Yeah it would be good to have a savvy beta tester, the step/dir and encoder will work but the I/O wont work yet
[00:06:24] <andypugh> I can start tomorrow.
[00:06:55] <PCW> andypugh I ran the servo thread at 4KHz so high speeds dont generate big angle steps

[00:08:03] <andypugh> I don't think that I would have the problem on anything with hardware attached. It's a bare-motor problem I think.
[00:08:15] <PCW> We still need to add phase angle extrapolation to avoid the steps

[00:08:40] <PCW> (to the 8I20 firmware)
[00:09:52] <andypugh> That might make hall-commutation friendlier too.
[00:10:22] <PCW> The current PI loop/Clark/Park stuff dont like steps too much
[00:10:22] <andypugh> (and might cause problems with noisy feedback devices like cheap-ass Arduino resolver hardware)
[00:11:20] <andypugh> I put a clumsy sort of filter in my Arduino code. Reading Wikipedia today, it's actually a basic Kalmann filter. So I seem to have reinvented the Kalmann filter :-)
[00:12:21] <PCW> The extrapolator is effectively low pas filltered
[00:12:28] <PCW> pass
[00:12:52] <PCW> only needs to track sane accelerations
[00:13:05] -!- Loetmichel has quit [Ping timeout: 276 seconds]
[00:13:57] <andypugh> Is the 7i76 a smart-serial device? I am curious how the 5i25 supports ordinary breakouts and the 7i76?
[00:17:16] <Jymmm> Maybe someone can point me in the right direction (metalurgical wise)... I took some heavy duty kitchen foil, folded it 4x as thick. Molded it into a cup shape added water for 24 hours, and the water leaked/seaped through the foil. How does that happen?
[00:17:21] <PCW> The 7I76 GPI/O and SPINDLE are done with a smart serial device on the 7I76 card. The 7I76 also has a RS-422 interface for one more SSERIAL device
[00:17:58] -!- Loetmichel [Loetmichel!Cylly@p54B1502D.dip.t-dialin.net] has joined #emc
[00:18:49] <andypugh> Reading the manual, it seems that the 5i25 comes pre-configured with firmware. Does that mean that EMC2 can't change the firmware, or just that it doesn't need to?
[00:19:00] <PCW> the 5I25 only works with DB25 type breakouts (but for example theres a 7I74 which is just like the 7I44 but has a DB25 instead of 50 pin header)
[00:19:09] <andypugh> Jymmm: It probably tore at the coreners.
[00:19:58] <Jymmm> andypugh: I had read an article which talked about it, so I thought he was full of shit. As such, I made sure that wasn't the case. It leaked.
[00:20:28] <JT-Shop> I have some spare drives and steppers to hook up to the 7i67 to test with down in the beer cave before making the swap on the plasma
[00:20:43] <Jymmm> andypugh: try it with a single layer if you don't want to wait 36 hours.
[00:20:55] <andypugh> Jymmm: Did you try it with coloured water? It could actually be condensation.
[00:20:58] <PCW> Currently EMC cannot change the firmware, nothing really difficult but the tools not there yet
[00:21:00] <PCW> Also you have to power cycle the computer after new firmware is written to the EEPROM before it can be used
[00:21:24] <JT-Shop> on the 5i25?
[00:21:30] <PCW> Yes
[00:21:32] <andypugh> The Hostmot2 manpage is going to be even more crazy soon then.
[00:22:02] <PCW> The 5I25 works fine as is, just dont specify a bitfile
[00:22:41] <Jymmm> andypugh: This is what I was testing... http://bepreparedtosurvive.com/Don%27t%20Trust%20Aluminum%20Foil.htm the last pic doesn't look like condensation to me.
[00:24:54] <Tom_itx> is that your page?
[00:25:16] <Jymmm> Tom_itx: Oh HELLO NO! Just something I stumbled across
[00:25:20] <Jymmm> -O
[00:26:34] <andypugh> Single layer of Bacofoil in a collander in a washing up bowl. No leaks so far, will check again in the morning.
[00:27:05] <Jymmm> andypugh: Thanks for testing. I wonder if it's an American foil mfg thing.
[00:27:55] <Tom_itx> aneal it first
[00:28:13] <Jymmm> Tom_itx: But they do have some neat products they sell
[00:28:16] <andypugh> Maybe. Bacofoil has a pretty diamond pattern embossed in it. Not sure why.
[00:28:23] <Jymmm> a couple of them that is
[00:29:13] <Jymmm> I thought al foil would be good in a pinch, but since they said it USED to hold water, if I'd have to try SS Foil instead
[00:30:07] <Jymmm> I did find food grade SS foil, but a bit pricy.
[00:30:32] <andypugh> http://www.baco.co.uk/products/product_11.shtml is perfectly watertight in a single layer so far.
[00:31:15] <Jymmm> That sure does look a LOT like Reynolds brand packaging
[00:31:32] <andypugh> Right, time to sleep. More results in the morning.

[20:09:02] <syyl> since we have a renishaw at work, I want one too :D

[20:15:10] <diego> hi, I´m Diego from argentina, i dont know what is the accepted protocol here to introduce me
[20:15:53] <jthornton> just ask your question
[20:16:00] <andypugh> Saying "hi" is enough :-)
[20:16:07] <diego> hi so

[20:18:36] <andypugh> PCW: Very basic question. Is the 7i76 expected to show up in smart-serial probe? The 7i69 plugged into it does...

[20:19:46] <diego> i´m working in a bed type milling machine, today i put togueter a dc motor and hall based encoder and try the pluto servo sample int he emc ... it works ok. My question is someone can tell me if using the pluto servo is a reliable option
[20:22:23] <andypugh> It doesn't have a reputation for reliably working with all PCs, but if it works with your PC it will continue to do so.
[20:22:40] <andypugh> There are many better options, though.
[20:23:01] <cradek> the pluto hardware is junk, and costs almost as much as very good options from mesa
[20:25:08] * JT-Shop wonders if the nice lady at Mesa found any 7i67's

[20:25:24] <JT-Shop> my current fun project http://imagebin.org/176889
[20:25:39] <syyl> yeah
[20:25:59] <syyl> ready for the zombie apocalypse
[20:26:02] <sarariman_seb> tripod crossbow
[20:26:04] <sarariman_seb> sweet
[20:26:27] <syyl> are those leaf springs from a truck?
[20:26:33] <sarariman_seb> the bow arms look like leaf springs
[20:26:34] <sarariman_seb> heh
[20:26:45] <syyl> ;)
[20:27:13] <JT-Shop> yea, a small truck I think
[20:27:27] <JT-Shop> just the long leaf
[20:27:38] <Danimal_garage> ah, finally replaced the cracked screen on my phone
[20:28:32] <syyl> so, made a overall view with some measurements :D
[20:28:33] <syyl> http://dl.dropbox.com/u/24396704/syylishaw.pdf
[20:28:44] <syyl> i think i will go for this design
[20:31:08] <diego> this is a hard to digest answer :( i know that are better options, sadly i´m on the cheap side and i will make the h bridges and encoders and need to connect the hardware to the emc2 so the pluto servo card
[20:31:14] <syyl> got it retty compact...
[20:31:59] <JT-Shop> bottom set of screws for centering?
[20:32:30] <syyl> no, those are for "clamping"
[20:32:36] <andypugh> diego: Do you already have the Pluto?
[20:32:38] <syyl> they pull the probe against the shank
[20:32:40] <diego> can someone recomend me a mesa card
[20:32:49] <JT-Shop> looked like the top ones clamped it in
[20:33:09] <andypugh> If you are on a budget look at the 7i43 and the 5i25.
[20:33:20] -!- micges [micges!~x@aedx138.neoplus.adsl.tpnet.pl] has parted #emc
[20:33:21] <syyl> with the upper ones, you push it centered
[20:33:23] <andypugh> Both are around $80
[20:33:38] <JT-Shop> I see
[20:33:39] <syyl> its a shameless copy of the original renishaw principle..
[20:33:55] <diego> yes, the pluto arrived yesterday and in the morning i made a test bed and works ok (the doc is not so good so)
[20:33:55] <syyl> i was pretty amazed, how primitive it is
[20:34:40] <JT-Shop> do you have a 3-model of it that you can share?
[20:35:01] <andypugh> diego: 7i43 plugs into the parallel port like a pluto, with the difference that it actually works. The 5i25 is a small-format PCI card which creates a super-parallel port. I think the 7i43 is probably the best for what you sound to be building.
[20:35:13] <syyl> i think i can export a stl or iges model for you?
[20:35:25] <syyl> eh
[20:35:30] <syyl> step, not stl
[20:35:33] <andypugh> diego: But if you have the Pluto, you might as well continue with it.
[20:35:42] <JT-Shop> step is good for me I use Solidworks
[20:36:16] <andypugh> syyl: It's not primitive, it's simple. The cleverness is in how very simple it is.
[20:36:18] <JT-Shop> SW claims to open up almost anything
[20:36:19] <sarariman_seb> i wish peter made an $80 pci board with mesa-standard 50-pin connectors, like a 7i43 with pci instead of epp
[20:36:39] <JT-Shop> that would be neat
[20:36:43] <syyl> hmm, yes, you are right andypugh, used the wrong words
[20:37:00] <andypugh> sarariman_seb: The 5i25 not to your liking?
[20:37:33] <JT-Shop> syyl: normally I can open pro e files usually sometimes without errors :/
[20:37:38] <sarariman_seb> i haven't looked at it very closely, doesnt it have some funny pinout? it wont plug easily into anyio daughterboards, right?
[20:37:39] <andypugh> Actually, 5i25 is a bit of a departure.
[20:38:39] <andypugh> Well, I had a 5i25 plugged into a 7i76 and an 8i20 a few minutes ago. Now it is a 7i76 and 7i69
[20:38:52] <sarariman_seb> did you have to make custom cables?
[20:39:35] <andypugh> Depending on the firmware installed (which is not emc2-downloadable) it can have a standard parport pinout (but faster) for Geckos, or smart-serial, or others.
[20:39:52] <andypugh> Cables came with it, but they are not very custom.
[20:40:13] <sarariman_seb> sounds like a very useful board, but not for what i need
[20:40:22] <andypugh> One is a fully-wired parport.
[20:40:28] <diego> The question is about the reliability of the software side of the pluto - emc2 integration, the future support of this solution. I know that the pluto servo is only a fpga and nothing more
[20:40:29] <sarariman_seb> i need to talk to a 7i33 and a couple of 7i37's
[20:41:00] <andypugh> The software is reliable if your PC comms with the board works.
[20:41:22] <sarariman_seb> diego, i think most folks who want an fpga on a parallel port have moved from pluto to the mesa 7i43
[20:41:38] <sarariman_seb> it may still work, but there probably aren't a lot of people using it
[20:43:20] <diego> ok <sarariman_seb> i will check the mesa card. Thanks for the answers.
[20:43:56] <JT-Shop> pcw said the cable is an IEEE-1284-M-M stock cable
[20:44:29] <andypugh> It is possible that the Pluto hardware has improved, too.
[20:46:26] <sarariman_seb> JT-Shop, so that cable wont let you connect the 5i25 to the standard anyio daughterboards :-(
[20:47:10] <sarariman_seb> andypugh, it's possible the pluto hardware's gotten better, but there's now not many emc2 developers who have that hardware and are interested in improving the firmware and software
[20:47:26] <PCW> The 5I24 is the 50 pin equiv of the 5I25 but not done yet
[20:47:36] <sarariman_seb> awesome!
[20:47:44] <andypugh> Good point seb, I just hate to see someone giving up on their new hardware the day they get it.
[20:47:51] <sarariman_seb> how to you change the firmware on the 5i24?
[20:48:04] <sarariman_seb> can you reprogram it from the pc like you do the 5i20 etc?
[20:48:13] <PCW> Same as 5I25 load it onto EEPROM
[20:48:29] <sarariman_seb> i see
[20:48:55] <PCW> EEPROM is downloadable from PC side (a bit like performing an appendectomy on yourself)
[20:48:56] <sarariman_seb> why is it different? is the pci interface on the fpga, rather than in a separate chipset?
[20:48:59] <andypugh> PCW: This is a very basic question, but it 7i76 Sserial, and parameter-discoverable?
[20:49:19] <PCW> Yes PCI in FPGA
[20:49:55] <sarariman_seb> that'll probably take some driver-fu to support… i assume the pci device leaves the bus and a new one shows up when you reprogram it?
[20:50:07] <PCW> Some of 7I76 (the field I/O) is sserial and discoverable (but you wont see it yet)
[20:50:58] <PCW> The reason you wont see it yet is that I have not finished the manual that tells you where to apply field (8-24VDC) power
[20:51:21] <andypugh> Ah, I will stop worrying about not seeing it then, and get on with supporting the 6i69 (which I can see, and is being discovered)
[20:51:24] <PCW> sarariman_seb yes
[20:51:44] <andypugh> I was wondering if it needed power :-)
[20:51:55] -!- MOGLI [MOGLI!~MOGLI@1.38.97.150] has joined #emc
[20:52:06] <PCW> Andy: the field I/O is isolated from the PC so needs field power to even talk
[20:52:11] <diego> <sarariman_seb> the pluto pinout is almost unusable, the only option is to make a custom cable
[20:52:47] <sarariman_seb> PCW, that might be tricky… The "old" device is discovered by the kernel, the hm2_pci probe function gets it and hands it to the hostmot2 driver, just like normal
[20:53:14] <sarariman_seb> but then if the hostmot2 driver wants to reprogram it, the device disappears, right as hosmot2 and hm2_pci are initializing it
[20:53:28] <andypugh> I just counted. There are 13 Mesa cards in the room with me, and one more in the garage. I could open a shop!
[20:53:39] <sarariman_seb> then a new device appears, gets handed to hm2_pci, and it starts over again
[20:53:45] <Danimal_garage> lol
[20:54:05] <sarariman_seb> we'd have to teach the hostmot2 driver to probe for firmware version and not reprogram it if it's already the right one
[20:54:06] <Danimal_garage> i think i have 11 andypugh
[20:54:14] <Danimal_garage> they're all in machines
[20:54:20] <PCW> Since you are writing the EEPROM, its probably bets just to have an external utility to update configs
[20:54:25] <PCW> best
[20:54:30] <sarariman_seb> beets
[20:54:39] <PCW> I like beets
[20:55:21] <Danimal_garage> beets are gross
[20:55:36] <PCW> beet haters are gross
[20:55:38] <Danimal_garage> i'm a meatatarian
[20:55:44] <sarariman_seb> FIGHT!
[20:55:59] <cradek> mmm beets
[20:56:01] <Danimal_garage> save a beet, eat some meat
[20:56:18] <andypugh> diego: It's a pity you don't ask here first. But there is no reason you can't make your driver circuits and see how it goes, then keep the option of a change to Mesa (or Motenc, or others) later
[20:56:40] <diego> our office has a side painted purple...like a beet
[20:56:53] <sarariman_seb> i only eat office buildings
[20:57:16] <Danimal_garage> holy crap it's lunch time
[20:57:30] <andypugh> You are making me hungry (the beet talk, not the meat talk)
[20:57:31] <Danimal_garage> time flew by
[20:57:50] <Danimal_garage> the beet talk is counteracting my hunger from the meat talk
[20:58:27] <PCW> "but then if the hostmot2 driver wants to reprogram it, the device disappears, right as hosmot2 and hm2_pci are initializing it"
[20:58:29] <PCW> Actually you write new EEPROM data then tweak the FPGA (Reload thyself command) this should only take about .4 seconds
[20:59:18] <PCW> but like I said you dont want to do this unless you need to change firmware
[20:59:22] <diego> <andypugh> the 60$ shipped made a pluto board the first and only option here in argentina , after all is a hobby for me, i made these www.wzl.com.ar
[20:59:32] <Danimal_garage> the only way i'll eat vegitables is if it's stuffed inside intestine skin with meat
[21:00:13] <Danimal_garage> or in the form of a french fry
[21:00:19] <Danimal_garage> or refried beans
[21:00:30] <Danimal_garage> or guacamole

[22:51:25] <sarariman_seb> the firmwares in hostmot2-0.8 still have V2 muxed encoders

[22:57:57] <sarariman_seb> ah ok
[22:58:09] <sarariman_seb> what's the issue exactly? the issy-issue?
[22:58:14] <issy> i am gething the same readings of encoder 0and3
[22:58:31] <issy> but i have connect encoder only to chenal0
[22:59:15] <issy> the test are in halrun
[22:59:50] <andypugh> Could be hardware. Multiplexers hold state on unconnected pins.
[23:00:17] <andypugh> Can you connect an encoder to Chan 3?
[23:00:25] <andypugh> (Any encoder)
[23:00:27] <issy> yep , i try
[23:00:46] <issy> is the same , like is not connected
[23:00:53] <andypugh> OK.
[23:00:57] <andypugh> Just an idea.
[23:01:15] <sarariman_seb> you have an encoder plugged in to channel 0, and nothing else connected?
[23:01:22] <issy> yes
[23:01:27] <sarariman_seb> and channel 0 is showing correct?
[23:01:46] <issy> the first 3 chanels are ok.
[23:01:50] <sarariman_seb> unconnected channels have undefined values, i wouldnt worry about it
[23:01:55] <issy> the muxed onces are not
[23:04:21] <andypugh> I think he said it was the same with an encoder on 3
[23:06:48] <issy> i am gething the same reading on both chanels normal and muxed , but i have only on the normal chanel encoder , the nuxed is empty
[23:08:25] <issy> the mux signal must work at servo tread right?
