[00:14:39] <owhite> people, I am upgrading from an old version of emc2 to 2.5.1. I used to use a very early version of the component hal_m5i20, which has been deprecated to hal_pci. Would anyone have any suggestion for the firmware that I could load that reproduce the pins that were created in hal_m5i20 in the new components?
[00:15:11] <owhite> *reproduces
[00:15:54] -!- gmagno has quit [Quit: Enough small talk...]
[00:16:39] <PCW> unfortunately theres no 1-1 firmware/driver that replaces the pins (the pin names come from the driver)
[00:17:50] <owhite> okay. Any recommendation for what I would do next?
[00:18:23] <PCW> so this is a servo config?
[00:19:36] <owhite> no. My m5i20 board connects to a custom made pcb, that I use to measure and send digital signals to a laser. So all my pins are used for digital I/O.
[00:23:53] <PCW> so basically you will just have to rename the I/O bits (and set output bits to output mode)
[00:24:17] <jdh> do you vent your oil pumps after changing oil?
[00:24:24] <jdh> <urk>
[00:25:35] -!- sumpfralle has quit [Ping timeout: 260 seconds]
[00:25:54] <owhite> and to input mode yes. The problem is that I'm using the (really great) pncconf, it keeps complaining I "forgot to designate a stepper or pwm signal for axis X", well, I'm not driving steppers, and it doesnt let me move to the next configuration page.
[00:26:20] <andypugh> owhite: Basically you can use any firmware at all in that case, but need to declare zero of all the functions (like stepgens and encoders)
[00:26:41] <andypugh> However, it seems like an odd way to use a Mesa card.
[00:27:06] <owhite> well I maxxed all the i/o on my parallel ports. >shrug<
[00:27:49] <owhite> andypugh, I do that, any idea why the pncconf wont let me pass the error I'm getting?
[00:27:58] <andypugh> A 7i43 on the parport would have been cheaper.
[00:28:42] <andypugh> I am afraid I know almost nothing about pncconf.
[00:28:43] <PCW> probably because its pretty rare not to use at least some hardware in the FPGA
[00:28:44] <owhite> when I bought my m5i20 I dont believe they had components for the 7i40.
[00:29:03] <owhite> *7i43.
[00:29:19] <andypugh> No, if you are using that driver then support wasn't there for the parport cards.
[00:29:43] <PCW> you could take the pncconf generated file and patch it later
[00:30:43] <r00t4rd3d> lol, ger21 removed the images of my mini paradise box off cnczone.
[00:30:49] <andypugh> pncconf might be rather over-kill for the application, too.
[00:31:36] <PCW> That is edit by hand = set config line in inifile so all stepgens etc are set to 0
[00:31:38] <PCW> and remove lines in HAL that use the stepgens etc
[00:31:47] <andypugh> You could probably take the old config and fix it with copy-and-replace in gedit
[00:32:20] <owhite> okay, hang on...
[00:34:22] -!- Valen has quit [Quit: Leaving.]
[00:34:50] <PCW> might be easier to start with the hm2 servo example files hm2-servo.hal and 5i20.ini
[00:37:11] <PCW> or setup what you can in pncconf and hand edit the result to turn off the 1 stepgen and add your I/O thats on the stepgen pins
[00:37:12] <PCW> unlike m5i20, hm2 will allow you to use all 72 I/O bits as GPIO in any mix of in/out/opendrain
[00:37:47] <owhite> PCW: sounds great. I can do that -without- using the pncconf?
[00:38:29] -!- micges has quit [Quit: Leaving]
[00:39:01] <PCW> disconnect any daughtercards
[00:39:02] <PCW> start linuxcnc and select hm2servo .. 5i20 from the menu
[00:39:13] <owhite> done.
[00:40:20] <PCW> this will install the /linuxcnc/configs/hm2servo directory and the hm2-servo.hal and 5i20.ini files in that directory
[00:40:26] <owhite> done.
[00:40:57] <PCW> now you can edit the 5i20.ini file to set all the PWMGENS and ENCODERs to 0)

[00:42:27] <owhite> CONFIG="firmware=hm2/5i20/SVST8_4.BIT num_encoders=0 num_pwmgens=0 num_stepgens=0"
[00:42:56] <PCW> yeah
[00:44:36] <owhite> then customize in the hal file, using "in, out, is_opendrain, is_output"
[00:45:08] <owhite> as in: "setp hm2_[HOSTMOT2](BOARD).0.gpio.048.is_opendrain 1"
[00:45:17] <PCW> Yes, maybe using your partially correct pncconf generated file if you prefer
[00:45:48] <owhite> no. I'll start from scratch. But I think I get the idea.
[00:47:18] <owhite> sorry, I just didnt get that I could configure the firmware at this level, I think those features werent available when i first implemented the m5i20.
[00:47:40] <owhite> i think it was sort of "takeitorleaveit" at that point.
[00:49:02] <PCW> Yeah I think the IO bits had a DDR at the hardware level but the driver simplified things into hardwired groups of 8
[00:49:26] <PCW> m5i20 is really old (5-6 years?)
[00:49:54] -!- adb has quit [Ping timeout: 264 seconds]
[00:51:12] <owhite> I posted this after I made the whole system.... http://wiki.linuxcnc.org/cgi-bin/wiki.pl?M5i20_Laser
[00:51:19] <owhite> but there isnt a date stamp on the page.
[00:53:19] <owhite> you can see the whole system is pretty noodle brained since the m5i20 is connecting to a board that makes PWM signals, which the m5i20 could now do on its own.
[00:53:38] -!- leehambley has quit [Ping timeout: 252 seconds]
[00:54:06] <andypugh> Any advantage in deleting the board?
[00:54:46] <PCW> yeah it can, and if you give me your pinout I can make bitfile that puts the pwmgen on the pin you want
[00:55:27] <PCW> deleting which board
[00:55:32] <PCW> ?
[00:56:36] <PCW> If you were generating steps, you can do that in hardware as well
[00:57:03] <owhite> PCW: thanks for the offer. If I go with upgrading the interface to the laser I could take you up on that. If andypugh is asking the question am I ready to eliminate my outdated system, I dont quite see the need for the additional time investment.
[00:58:08] <owhite> I still need to have some additional electronics to interface to the laser, because the manufacturer (Coherent) did not use entirely digital control. They used line driver ICs as part of the interface.
[00:58:12] <andypugh> There is a 5i20 connecting to a board that does a lot of things that the 5i20 is good at. I am wondering if that board does anything that the 5i20 can't do.
[00:58:55] <owhite> andypugh: yes, see above. That being said, it now could be much more elegantly handled given the increased flexibility of the m5i20.
[00:59:24] <PCW> well good luck updating its time to shuffle off to buffalo...
[00:59:31] <owhite> I also have other things that are run by digital I/O using the parallel ports, they could all be consolidated into one system.
[00:59:36] <owhite> PCW: thank you for your help.

[03:02:14] <lwizardl> for a small starter mill what do they usually cost for a starter build?
[03:07:32] <Tom_itx> 2k
[03:08:18] <lwizardl> about what I though
[03:10:38] <lwizardl> t
[03:10:59] <Tom_itx> slow connection?
[03:12:30] <lwizardl> no just was reading a couple pages and noticed i forgot the t

[03:48:33] <MattyMatt> 2k is more than I'd spend
[03:48:51] <MattyMatt> HF mill and ebay steppers
[03:49:56] <MattyMatt> less than 1k for that way
[03:50:06] <lwizardl> hf mill?
[03:50:15] <MattyMatt> my plywood monstrosity was $500 or so
[03:50:35] <MattyMatt> harbour freight. cheapo $400 mill
[03:50:44] <lwizardl> I'd be fine with like plywood or mdf
[03:50:45] <lwizardl> ah
[03:51:31] <MattyMatt> plywood dremel pusher is annoying. for metalwork I'd rather have something smaller made of metal
[03:51:57] <lwizardl> I am mainly going to start off making stuff from plastics
[03:52:07] <MattyMatt> I tried to make something in between a mill and a router
[03:52:13] <lwizardl> like laptop cases etc
[03:52:41] <MattyMatt> http://imgur.com/a/DNWJq#2
[03:52:57] <MattyMatt> ah mine is actually just about the right size for that
[03:53:27] <lwizardl> cool
[03:53:48] <MattyMatt> laptop cases could be done on a proper flatbed. my machine has a lot more Z than you find on most routers
[03:54:02] <lwizardl> i'm more of a console game modder so being able to do things for those are a plus
[03:54:37] -!- leehambley has quit [Ping timeout: 245 seconds]
[03:54:42] <lwizardl> but I also would like to be able to use the cnc mill for cutting the boxes to store my frankenstein stuff in
[03:55:05] <MattyMatt> ah right sounds like you want a flatbed rather than a vertical mill
[03:55:13] <lwizardl> yeah
[03:55:34] <MattyMatt> something like the fireball v90 is a basic one of those
[03:55:47] <lwizardl> like I think I want this but not sure its worth $230. http://www.youtube.com/watch?v=P8jbtRTV6uw
[03:56:03] <MattyMatt> http://www.probotix.com/FireBall_v90_cnc_router_kit/
[03:57:07] <MattyMatt> ouch extra $200 for T slot bed. that thing ain't as cheap as I thought
[03:57:21] * MattyMatt looks at your vid
[03:57:43] <lwizardl> it is basically a razorblade holder that pivots

[03:58:40] <MattyMatt> yarr nifty. I might make one for me :)
[03:59:19] <MattyMatt> $230 just for the knife? ridiculus
[03:59:53] <lwizardl> yeah that was what I thought
[03:59:56] <MattyMatt> ridiculissimus
[04:00:13] <lwizardl> it comes in a cnc cut block of wood case with the blades, holder, and allen key
[04:00:22] <lwizardl> but still maybe if it was $100
[04:00:31] <lwizardl> i'd think thats worth it
[04:01:05] <lwizardl> looking at your pictures
[04:01:22] <lwizardl> is that cat5 cable ?
[04:01:53] <MattyMatt> you could make stuff like that on a vertical mill, but not on a flatbed router. that's why I'd rather have one of those most of the time
[04:02:54] <MattyMatt> yeah on the motor there cat5. 2A motor and the conductors are doubled. that's marginal but works
[04:03:43] <MattyMatt> it's only a 2ft run to the driver
[04:05:08] <lwizardl> hehe just was looking at the pics and thought it was networking cable
[04:05:19] <lwizardl> I have used those for other stuff often
[04:08:18] <MattyMatt> http://www.harborfreight.com/two-speed-variable-bench-mill-drill-machine-44991.html cheapo mill (can be had much cheaper 2nd hand)
[04:09:00] <MattyMatt> one of those, stepper motors, toothed pulleys and belts
[04:09:27] <MattyMatt> and a vice and other miscellaneous clamps
[04:09:34] <MattyMatt> total around $1000
[04:09:50] <MattyMatt> a bit of tooling of course
[04:10:48] <lwizardl> yeah I bought this book for building them. Just haven't read it fully yet
[04:10:48] <lwizardl> http://buildyourcnc.com/
[04:10:58] <r00t4rd3d> http://www.microcarve.com/mcMV1.html
[04:11:16] <MattyMatt> spending a bit more on the motor drivers tahn I did would be worthwhile I think. I persevere with the classic crappy chinese 4 axis
[04:11:48] <lwizardl> r00t4rd3d, yeah says electronics not included
[04:12:45] <r00t4rd3d> 3 steppers , a controller, spindle w/ mount
[04:14:01] <r00t4rd3d> for 700 though I could build a sweet machine
[04:14:07] <r00t4rd3d> alot bigger then that one

[04:23:58] <r00t4rd3d> http://www.youtube.com/watch?v=jAWF-qhh4pQ&feature=related
[04:24:34] <lwizardl> this peeked my interest even more in a cnc machine http://www.youtube.com/watch?v=ayYhBhYcJj0&feature=plcp
[04:25:41] <lwizardl> seems like a great was to create the mold for a vacuum former
[04:26:30] <r00t4rd3d> funny, I asked for the model files for that from them.
[04:27:32] -!- jdh [jdh!~jdh@miranda.org] has joined #linuxcnc
[04:28:34] <lwizardl> i would also
[04:32:20] <MattyMatt> or you could do it negative and do fiberglass in it
[04:33:15] <MattyMatt> or as its against your face, you could do it positive so the shiny side is inside. you can sand the outside
[04:34:52] <lwizardl> yeah
[04:35:36] <lwizardl> for the last year or so I have been trying to decide which machine to build first. still leaning more towards cnc then vacuum former, and then 3d printer
[04:36:08] <MattyMatt> I did cnc then printer. no urge for vacuum former yet
[04:36:59] <MattyMatt> I got a lathe before I did the printer too. that pays a chunk of itself when making the printer
[04:37:58] <lwizardl> yeah
[04:38:24] <lwizardl> plus i bet the parts last longer made of wood versus plastic
[04:38:50] <MattyMatt> not really. opposite if anything
[04:39:11] <MattyMatt> wood's only real virtues are it's cheap and light
[04:41:27] <MattyMatt> and easy to work, but no easier than plastic. you can use woodwork tools and techniques on plastics
[04:42:12] <MattyMatt> and plastics you don't have to worry about grain and splitting
[04:43:05] <MattyMatt> I'd avoid a lot of pain and go straight to aluminium
[04:43:25] <MattyMatt> unless you are really skint, in which case wood gets you going

[11:05:06] <aircraft> i'm think about swithing my cnc to serial interface, can someone point me to a good implementation?
[11:05:33] <jthornton> serial?
[11:05:51] <aircraft> yes
[11:06:06] <aircraft> to RS485 for example
[11:06:38] <jthornton> you would have to have some smart hardware on the other end
[11:06:48] <jthornton> but why serial?
[11:07:32] <aircraft> because parallel has limited number of ios
[11:08:03] <jthornton> Mesa 5i25 7i76 combo is the way to go for a stepper driven machine
[11:08:06] <aircraft> i kno what i will need some smart hw and plan to make it
[11:09:21] <jthornton> you will also need to write a program to go along with your smart hardware
[11:10:07] <aircraft> i have some experience already
[11:10:35] <aircraft> but it was not realtime
[11:10:50] <jthornton> neither will the serial interface
[11:11:15] <jthornton> so this is not to gain I/O but for the experience?
[11:16:44] -!- Poincare [Poincare!~jefffnode@] has joined #linuxcnc
[11:16:45] <aircraft> for both i think
[11:18:33] <jthornton> you do know that for $200 you get 5 Axis of step &dir step motor or servo motor drives and also provides a spindle encoder interface, isolated analog spindle speed control and 48 isolated I/O points for general purpose field I/O use. with a 5i25/7i76?
[11:19:07] <jthornton> I guess that depends on what part of the earth your located in though

[11:45:27] <Valen> aircraft: google at linuxcnc latency
[11:45:30] <jthornton> just curious what is the latency of your laptop?
[11:46:43] <jthornton> aircraft you might look at the gs2 component for inspiration. It uses modbus over the serial port
[11:46:58] <aircraft> why it must be big for laptop?
[11:47:43] <jthornton> what is "it"?
[11:47:46] <aircraft> many people succefully using Atom boards
[11:48:05] <aircraft> latency
[11:48:11] <jthornton> the Atom is a favorite motherboard
[11:48:33] <jthornton> laptops have power saving hardware that causes the latency to be big
[11:48:42] <jthornton> desktops do not have this problem
[11:49:24] <aircraft> Atom doesn't?
[11:51:02] <jthornton> desktop motherboards do not have the same "features" that laptops do
[11:51:53] e-ndy- is now known as e-ndy
[11:53:11] <aircraft> what features exactly?
[11:53:19] <jthornton> power saving
[11:53:23] <aircraft> speedstep?
[11:53:41] <jthornton> ?
[11:54:15] <Valen> run latency test and have a look
[11:54:33] <jthornton> laptops are designed to run on battery so they have hardware to conserve power that interrupts the CPU

[13:58:52] <aircraft> jthornton, where i can found more info about rt issues on laptops?
[14:04:34] <Jymmm> Laptops have power management that interferes with real time operations.
[14:06:33] <aircraft> very abstract
[14:06:59] <aircraft> i need more detailed info
[14:14:21] <mazafaka> aircraft: i tried two laptops, one was not working with RTAI at all, another one worked, but I think it was badly cooled down in this mode
[14:16:41] <mazafaka> aircraft: general idea is you heat up the laptop too much (due to its design and purposed working regimes) when you use rTAI mode and by this mean turn off the ACPI features
[14:18:41] <mazafaka> aircraft: if it makes any sense, I previously used badly-cooling desktop for FEA calculations, had to put it next to the window in winter, and open it

[15:11:48] <mazafaka> aircraft: exactly. oposite to desktops, they're badly-cooled thingies and manufacturers understand it and make them reliable by some means. Another question is, why can not you afford a desktop with old CRT monitor altogether for somewhat like 100 USD?

[15:15:46] <mutilator> orly?
[15:15:48] <mutilator> what card?
[15:15:57] <mutilator> cause i'd prefer to use my old laptop to a old desktop
[15:16:30] <JT-Shop> aircraft: a BOX525 Atom board is smaller than most laptops :P
[15:16:40] <aircraft> it is noname brand card on OXmPCI952 chipset
[15:17:06] <aircraft> JT-Shop, yep
[15:17:16] <skunkworks> I have had only 1 laptop so far that had decent realtime performance - you are lucky
[15:17:43] <skunkworks> The card isn't what dictates the realtime performance - it is the computer
[15:17:52] <mazafaka> aircraft: at work, we have some DOS-based thingie which does not miss steps (although the machine turns off with errors sometimes). But Ubuntu-based LinuxCNC offers QCAD and HeeksCNC right in RTAI mode, so it worth to have such a workstation.
[15:18:44] <aircraft> JT-Shop, btw, is were any differens between ITX atom board and netbook motherboard?
[15:19:19] <mazafaka> netbook = small size, bad cooling, manufacturer's alteration in BIOS
[15:19:33] <mazafaka> if I understand it correctly.
[15:19:40] <aircraft> a just ordered HP mini110 motherboard for 20$
[15:20:31] <aircraft> it doesnt have cooler but i can install large fan with heatsink on it

[19:38:30] <jrshaul> Has anyone here cut depron (or another polystyrene foam) with a laser?
[19:38:50] <jrshaul> Most people use a really small laser, sometimes with a nitrogen feed. I wantto use a larger (~100W) laser, but without.
[19:41:23] <fragalot> jrshaul: I think there are lots of 75W pre-filled chinese laser tubes on ebay
[19:41:29] <fragalot> they seem to work alright
[19:41:41] <jrshaul> The laser I have. The information on how to cut without mucking up the oam or the optics I don't.
[19:41:49] <jrshaul> (It's not my machine. I just get to use it.)
[19:42:00] <fragalot> Ah. No idea ^_^
[19:43:01] <c60> Is there any howto's about using gantrykins for a dual stepper axis?
[19:43:38] <andypugh> c60: Are you sure it is worth the trouble?
[19:44:03] <c60> well, I'd like to be assured it's square when I do a homing.
[19:44:17] <andypugh> You have two sets of limit switches?
[19:44:22] <c60> yes
[19:44:58] <c60> I have it all working with trivkin I guess right now.
[19:45:07] <andypugh> There is a sim-gantry component in the sample files, take a look at that. (in fact, have a play around with the sim to see if you can handle the inconvenience)
[19:45:18] -!- bradsimantel has quit [Quit: bradsimantel]
[19:45:26] <c60> what sort of inconvenience's does it impart?
[19:45:37] -!- nikosel has quit [Quit: Bye Bye]
[19:45:40] <andypugh> I _think_ that there might be a crucial line missing from the INI file if the sample too. Let me take a look.
[19:46:00] -!- vladimirek has quit [Remote host closed the connection]
[19:46:59] <c60> that would be helpful
[19:48:13] <andypugh> Right, I think that the [TRAJ]MAX_ACCELLERATION and [TRAJ]DEFAULT_ACCELLERATION are commented out. They need to not be, and the numbers must be less than the stepgen accell from the [AXIS_N] sections.
[19:49:36] <andypugh> The drawbacks are that you need to home in joint mode then switch to World mode. There is something wierd about the jogging too. I think you can only jog in one cartesian direction at a time or something similar.
[19:50:29] <c60> those aren't too major of an issue. I'm assuming you could always just go into MDI mode and say G1 X500 Y500 or whatever
[19:50:45] <c60> It said you could only jog continous not incremental
[19:50:45] <andypugh> Yes.
[19:50:48] <c60> no biggy
[19:50:51] <andypugh> That too.
[19:51:28] <c60> So would I be best to just take to the sim files and modify them to work, or try to hack in the sim stuff into my existing configuration?
[19:52:02] <andypugh> The best idea is probably to make a copy of your current config directory, change the name of the folder and the INI file inside, then work on that copy. Then you can start either as the mood takes you.
[19:53:58] <andypugh> And I would probably just edit the config. It's actually just a case of changing loadrt trivkins to loadrt gantrykins coordinates=XYZY (or whatever your config is) That's all it takes, I think.
[19:54:57] <c60> for sure, I really only need to run it when I'm off square,
[20:01:32] <jthornton> anyone want to play with this http://imagebin.org/232402
[20:03:44] <andypugh> Want to, yes. Have time for? No. I am involved in an arms-race with burglars. I am ahead so far, but they have come back three times this week.
[20:04:00] <jthornton> holy crap
[20:04:22] <jthornton> and you can't get the bobbies to hang around your place for a while
[20:04:28] <andypugh> Currently writing the G-code to make some more security stud things.
[20:04:31] <c60> time to get some camera's installed, and maybe plant a gps in something for them to steal
[20:05:07] <andypugh> What good would it do to know here some of my stuff was? I want them to not steal anything.
[20:05:38] <andypugh> And I am not sure why I would want pictures of them as a souvenir either.
[20:05:42] <c60> I guess it just depends if it's the same burglar or not,
[20:06:47] <andypugh> The neigbours reckon they recognised them.
[20:07:13] <c60> I saw a neat alarm once that was basically a smoke machine, it'd fill up your house or whatever and start strobing lights so they couldn't see anything. and it would make your house look super suspicious smoke and red billowing out.
[20:07:20] <jthornton> guessing you don't have a "rent a rottweiler" dealer nearby
[20:07:56] <andypugh> They only tried to get in once. (broke the garage/workshop door out of the tracks, but one corner was pinned down by https://picasaweb.google.com/108164504656404380542/CNCUnsorted#5800014699280725666
[20:08:13] <c60> but these aren't necesessarily deterrants.
[20:08:28] <andypugh> Then they came round again (I assume in case I hadn't fixed the door)
[20:08:50] <andypugh> My fear is that they will come round with tools next. So far they have been using brute force.
[20:09:14] <andypugh> So, I am making another of those for the other corner.
[20:09:30] <jthornton> I'll let you get back to work then
[20:09:31] <andypugh> The problem is that they have now seen how full of goodies that particular garage is.
[20:09:52] <jthornton> and the police are no help?
[20:10:09] <andypugh> What can they do?
[20:10:21] <jthornton> stake out the place
[20:10:23] <andypugh> There are a lot more garages than cops.
[20:10:28] <Tom_itx> so wire the door to mains
[20:10:58] <andypugh> Burglary is a low priority compared to wiring code violations :-)
[20:11:03] <jthornton> yes, but yours is of interest to them and they keep coming back so it is unique
[20:11:31] <andypugh> At least one other garage (that I know of) was attacked the same day.
[20:11:39] <jthornton> if you were closer I'd lend you the ballista
[20:11:43] <andypugh> I don't think they care _which_ enduro bike they steal.
[20:12:09] <jthornton> better get busy then and fortify your door up
[20:12:48] <Tom_itx> someone stole my rear fence gate once. nothing else
[20:14:02] <c60> A similar story was all over the news today in Calgary, someone's house had been burglarized several times in a couple weeks, so they put up camera's and of course had the picture of the theif on the local tv, the cops said it's very helpful when people do the detective work for them, but they didn't say they had arrested him yet,
[20:14:22] <c60> but a picture and gps coordinates of where they are might make the cops job too easy to pass on\
[20:17:52] <andypugh> OK, so why isn't my ngc file changing?
[20:18:20] <andypugh> (editing on one machine, viewing on another)
[20:18:59] <archivist> reload
[20:19:25] <archivist> save to the right place
[20:19:43] <cradek> stop making your life difficult and put the mac away
[20:19:46] <andypugh> I am fairly sure I am doing both.
[20:20:21] <andypugh> cradek: There are chairs here. The Linux machines are in the garage with horible keyboards.
[20:21:51] <archivist> spose I should unload todays pics from the model engineer ex

[22:39:09] <JT-Shop> does Galil cards have step and direction or velocity input?
[22:40:15] <jdh> I'm resisting the grammar correction.
[22:40:56] <JT-Shop> :P I just walked 5 miles out in the woods and was too tired to correct it once I saw it
[22:41:13] <jdh> no clue what you are talking about specifically, but I have some galil cards at work that do either
[22:41:26] <JT-Shop> neither do I
[22:41:31] <jdh> they are 1826's maybe?
[22:42:24] <JT-Shop> I've never seen one up close

[22:44:30] <JesusAlos> I want to use a 5i25 and 7i777 Mesa cards
[22:44:36] <jdh> one is on a 3 axis engraving system with servos. 6 others with probably the most expensive single axis step-dir system known.
[22:45:30] <jdh> huge card, big cable, really nice breakout board. 2 sets of wires going to a stepper drive.
[22:45:31] <JesusAlos> but Pncconf wizard no have 5i25 card option choice
[22:45:36] <JT-Shop> JesusAlos: does your drive take velocity input? and do you have encoder feedback?
[22:46:16] <JesusAlos> I don't Know the velocity but i have encoder control
[22:47:19] <JT-Shop> does the drive use +- 10vdc signal to control the servo?
[22:47:32] <jdh> yes
[22:47:38] <JesusAlos> yes
