[00:26:20] <Gamma-X> Anyone know a good way to make a spindle encoder for an rf45? its got a belt drive system on it...

[00:28:22] <CaptHindsight> Gamma-X: maybe an encoder on an idler on the belt
[00:28:47] <Gamma-X> CaptHindsight, can you clarify idler?
[00:29:33] <Gamma-X> oh I should have noted... it has a dual sized belt drive.
[00:29:34] <CaptHindsight> on a pulley
[00:30:24] <Gamma-X> CaptHindsight, I think I know what you mean... trying to stay away from that but it might be the nly way...

[01:01:32] <yedikilo> hi
[01:02:25] <yedikilo> i have a pmdx 126 board, do you think it will be possible to hook up more than one driver to one step/dir output?
[01:03:30] <yedikilo> i have 9 motors to drive which are all slaves to one motor
[01:03:42] <yedikilo> they will all do the same thing
[01:03:52] <yedikilo> i just dont have enough outputs to drive them all
[01:04:22] <yedikilo> but as they will be doing the same thing, is it possible to drive them with the same signal out of the break out board?

[01:31:05] <CaptHindsight> so they sell a belt drive conversion kit without including and encoder for the motor or pulleys
[01:31:14] <CaptHindsight> and/an
[01:32:41] <CaptHindsight> Gamma-X: so where do you prefer to mount the encoder?
[01:33:17] <Gamma-X> prefferably where all the gears ursed to be.
[01:33:37] <CaptHindsight> but not as an idler
[01:34:03] <CaptHindsight> so on what pulley or motor shaft is acceptable to you?

[01:44:02] <Gamma-X> no it do
[01:44:25] <Gamma-X> if I could mount it to the splined shaft I could mount it below the top plate where averything is seen.

[01:53:41] <archivist> take off the last pulley machine it to have a register to take an encoder disk
[01:54:46] <Gamma-X> archivist, can you show a photo? trying to understand concept...
[01:55:41] <archivist> also make sure the cable and encoder reader optos are between if the disk is on the outer of the pulley

[01:56:18] <archivist> that is mounted on the outer but does not need regular belt change

[09:48:25] <miss0r1> I am thinking of adding a relay to power the spindle on my new cheap chinese cnc mill 3020t. Anyone know of anyone who has done this before?
[09:49:40] <archivist> lots ask a better question :)
[09:50:24] <miss0r1> I made a REALLY nice pcb with it yesterday. alot nicer than I had thought it capable of.
[09:50:32] SleepCrime is now known as nylar
[09:50:39] <miss0r1> But it would be nice for it to be able to power up/down the spindle
[09:52:48] <miss0r1> archivist, I am going to use the 4th axis of the Tonsen 4-axis controller in this box, and just use the pin ment for 'direction' to power a transistor which in turn powers a relay. That doesn't sound complete off the wall, does it?
[09:57:10] <archivist> some of the break out boards have a relay already
[09:57:29] <miss0r1> this one doesnt: http://www.mycncuk.com/forums/attachments/schematics-datasheets-manuals/11039d1387390631-tonsen-4-axis-controller-bob-schematic.png
[09:58:31] <archivist> the moto connection
[09:58:36] <archivist> at the top
[09:59:08] <miss0r1> thats mounted to the 'strobe' pin - isn't that meant for PWM ?
[10:00:01] <archivist> can be or one of the 4th axis pins or whatever
[10:00:32] <miss0r1> I am just curious if the 5 volt supply of the board will drive a relay. I can't realy make that out
[10:00:32] <archivist> actually steal the enables
[10:00:59] <miss0r1> the 'enables' of the 4th axis?
[10:01:18] <archivist> you have three enables you only need one/none
[10:01:33] <archivist> I leave the drivers enabled
[10:02:16] <archivist> I dont want lost steps between enabled state to leave enabled
[10:03:00] <miss0r1> indeed. I am just thinking - why would X and A have the same 'enable' pin and why on earth is it mounted on pin 14? That could never be an output
[10:04:00] <miss0r1> it could... heh

[10:27:33] <miss0r1> Can someone help me understand if this is connect? : "net spindle-on => parport.0.pin-01-out" <- from my .hal file. When I then issue the m3 command from axis, the pin 01 of the part port should be '1' and when I issue command m5 it should be '0' right? The problem is, I can measure 4.3 volts on that pin no matter what.
[10:32:36] <Einar__> I think it should be motion.spindle-on.
[10:33:17] <miss0r1> I actually just made it work - apparently you need to define a speed first.
[10:33:29] <miss0r1> even thou the computer has no say in the spindle speed.
[10:35:06] <Einar__> And don't connect your parport directly to a relay! Even if it can drive it, the pulse when releasing it will kill your parport.
[10:37:39] <miss0r1> i'll put in a NPN transistor and place a flyback diode over the relay
[10:37:45] <miss0r1> That should do nicely I think

[13:01:11] <miss0r> Are there any nice tools for taking some export from diptrace and converting it to gcode for isolation milling?
[13:02:36] <archivist> ! its not free
[13:03:03] <archivist> and always use gerber output
[13:04:07] <miss0r> I have tried this pcb2gcode, but I can't make it work properly.
[13:05:24] <archivist> but you said earlier "I made a REALLY nice pcb with it yesterday. alot nicer than I had thought it capable of."
[13:06:01] <miss0r> Yeah, that was just a demo. Not really a testimony to my skills
[13:07:13] <archivist> remember milling will have difficulty getting small detail like a pro pcb maker
[13:08:11] <archivist> you need really good tooling for milling
[13:08:55] <miss0r> Well. I just did a quite simple design in diptrace (The board I will add to the controller to power up the spindle). I export it to gerber and convert it with pcbtogcode. And it gives me some g-code files, but also a jpec of how it will look: *uploading*
[13:09:40] <miss0r> http://picpaste.com/outp3_traced-Bw0IsNfl.png
[13:10:02] <miss0r> which is some mess.

[13:16:53] <ReadError> didnt do anything, for spindle speed..
[13:17:33] <miss0r> You didn't do a -metric or anything? aren't thoes values a bit strange in that case?

[13:19:56] <archivist> no
[13:19:56] <miss0r> I haven't had a measuring dial on it yet
[13:20:06] <archivist> time you did :)
[13:20:26] <miss0r> Indeed - I will fetch it tomorrow after work(a friend of mine has it)
[13:21:14] <miss0r> In the meantime I would like to make this work :)
[13:22:52] -!- helix247__ has quit [Ping timeout: 265 seconds]
[13:24:00] <archivist> making it work might mean setting a bit of backlash compensation
[13:24:36] <miss0r> I thought I did that.
[13:24:58] <archivist> if there is and spindle concentricity error it will cut a larger/wider path
[13:25:23] -!- ingsoc has quit [Quit: Leaving.]
[13:25:25] <miss0r> indeed
[13:25:37] <archivist> cant set backlash without measuring !
[13:26:27] <miss0r> well, not - but I gave it more room that it needed - allowing for tolerance.
[13:26:51] <archivist> can make it worse
[13:27:33] <miss0r> Your recommendation would be to wait until I get my dial back?
[13:28:16] <archivist> 0 backlash compensation till then yes
[13:28:38] -!- nylar has quit [Ping timeout: 240 seconds]
[13:29:03] <miss0r> indeed. I didn't touch the backlash compensation - I just made my pcb design a bit wider/larger than needed to compensate for "unforeseen movement"

[13:29:46] <miss0r> unless I understand nothing that the offset is really backlash compensation

[14:45:19] -!- ries [ries!~ries@] has joined #linuxcnc
[14:45:30] <CaptHindsight> there are lots to choose from
[14:45:39] <somenewguy> yeah thats the problem
[14:45:56] <somenewguy> was hopeing someone had some perosnal experiencec w/ one, I am really bad at making arbitrary decisiosn lol
[14:46:36] <CaptHindsight> the prices are dropping and the efficiency is going up
[14:47:00] <CaptHindsight> so don't spend $100 on what you can get for $20
[14:48:30] <CaptHindsight> and get something with either an enclosure that will last for a long time in that abrasive environment or something you can replace the cover on
[14:48:57] <somenewguy> yeah thats what I;m trying to figure out, the cover situatoin
[14:49:18] <CaptHindsight> rope light mounted above
[14:49:19] <somenewguy> I typically only blast glass, and the strip will be in the top corners out of the way, but I probably still need to prtect it
[14:49:44] <somenewguy> although for 13 bucks for a strip, I may just buy one, wire it up, and see if it is still working in 6 months
[14:49:51] <CaptHindsight> unless you blast it directly it should last for years
[14:50:02] <somenewguy> the cabinet came w/ a flourescent light which is useles, I can't even tell if its on or off
[14:50:37] <CaptHindsight> mine came with a lamp socket in one of the upper corners
[14:51:46] <CaptHindsight> I use actual sand in mine, after 5 minutes I have to wait for the dust to settle and I have a vac on it to recycle the sand
[14:52:14] <somenewguy> you don't use the vac while its running?
[14:52:34] <CaptHindsight> the fine particles get airborne and stay dispersed
[14:52:43] <CaptHindsight> the vac runs the whole time
[14:52:58] <somenewguy> ok,, thats what i do
[14:53:17] <somenewguy> although the cabinet is new to me, I used to use one at work all the dman time, but that was obvoiusly a much nicer unit
[14:53:42] <somenewguy> my shop vac seems to want to over heat when I use it like this tho... I might need to go get a HF special shop vac w/ the 5 year warrenty...
[14:54:17] <CaptHindsight> I use a small 5 -10 gal by Rigid from Home Depot
[14:54:22] <CaptHindsight> never overheats
[14:55:04] <somenewguy> mines an old craftsman that has always done an awesome job, so I don't wanna kill it any faster than I ahve to, must be 15-20 years old by now
[14:55:21] <CaptHindsight> i even have the air inlet filer in the opposite corner from the vac inlet
[14:55:45] <somenewguy> I modified mine to force the fresh air past the viewing window, seems to help clear it up faster
[14:56:04] <CaptHindsight> but after the particles break down it's like blowing talc around the inside
[14:58:32] <CaptHindsight> my cabinet is made of polycarbonate only 3/16th thick, so a rope light should last just as long or longer

[15:27:01] <zeeshan|2> just add another line
[15:27:03] <PetefromTn_> It was like it was always missing a file.

[15:27:15] <PetefromTn_> Connor Ya there man?
[15:27:16] <zeeshan|2> in the gcc command
[15:27:32] <zeeshan|2> its not compiling cause it doesnt have the modbus lib
[15:27:46] <PetefromTn_> No I think it had the library..
[15:27:52] <zeeshan|2> yea its got it
[15:27:58] <zeeshan|2> but gcc the compiler doesn't see it
[15:28:23] <zeeshan|2> cause its no -I commandline option to show where libmodbus files are
[15:28:31] <somenewguy> sweet thanks, that looks perfect
[15:28:33] <PetefromTn_> He even tried to download some kinda other compiler program something like boost etc.
[15:29:05] <zeeshan|2> did you get internet on your cnc comp
[15:29:12] <PetefromTn_> sure..
[15:29:19] <zeeshan|2> so he can remote in :P

[15:29:49] <PetefromTn_> Yeah that is what I was hoping.
[15:30:30] <PetefromTn_> He said he was going to try to comile the thing on another computer in his house and then once he gets the file compiled for my version of linux,linuxCNC he was gonna remot in with it.

[17:08:29] <CaptHindsight> now I'm wondering why this hasn't hit inkjet yet

[17:09:06] <CaptHindsight> but you could print them and make them throw aways like TIJ
[17:10:17] <humble_sea_bass> i'm gonna be a little ignorant for a second, can 3d printing heads create isotopic deposits of infused polymers
[17:10:19] <PetefromTn_> how does this actuator work in an inkjet situation?

[17:21:49] <CaptHindsight> yes, actual muscle is just alive and takes care of itself for a few decades
[17:22:06] <PetefromTn_> When I look at stuff like this it makes me wonder what the future will be like for my kids when robotics and tech merge with materials like this that can react and move with speed and power and are relativley simple to build.
[17:22:35] <CaptHindsight> repair people to live for 200 years
[17:22:41] <humble_sea_bass> reprap ppl
[17:22:46] <humble_sea_bass> copy paste
[17:22:47] <PetefromTn_> My wife DOES NOT LIKE robotics she thinks it is creepy.
[17:22:48] <CaptHindsight> but still no brain transplnts
[17:23:19] <CaptHindsight> I drove one home the other day, i was glad it didn't attack me
[17:23:49] <PetefromTn_> watching movies like I robot she tells me we need to stop working on that stuff but you can see the handwriting on the wall these technologies are coming whether they are used for good or bad LOL..
[17:24:09] <CaptHindsight> body parts are just around the corner
[17:24:24] <CaptHindsight> but how do you fix broken minds?
[17:24:29] <PetefromTn_> apparently not from most experts that is a ways off..
[17:24:46] <PetefromTn_> I can't fix mine LOL..
[17:24:58] <CaptHindsight> way off it the west due to patent issues
[17:25:08] <humble_sea_bass> we mapped the lobsters neural pathways
[17:25:24] <PetefromTn_> and no shortage of moral issues as well.
[17:25:24] <CaptHindsight> but maybe organ shops in China soon
[17:27:34] <CaptHindsight> it's similar to the internet, the tech is moving faster than the old controlling co's can keep up their business models
[17:28:07] <CaptHindsight> so you either try to put the genie back in the bottle (stop net neutrality) or the world moves on
[17:28:34] <CaptHindsight> thats why there are similar discussions about 3d printing now
[17:29:26] <CaptHindsight> the good thing is that crap like reprap steals much of the show and misleads people to think that the tech is only good for printing plastic crap

[17:36:00] <mcfloppy> someone expirience with engrave painted acrylic glass?
[17:37:25] <mcfloppy> i tried to paint a 2mm acrylic glas and engrave a mirrored Text on the painted side to illuminate from behind
[17:37:56] <CaptHindsight> what's the actual problem?
[17:39:00] <mcfloppy> the paint come off
[17:39:05] <Loetmichel> mcfloppy: you mean like this: http://www.cyrom.org/palbum/main.php?g2_itemId=13194
[17:39:25] <Loetmichel> or more like this: http://www.cyrom.org/palbum/main.php?g2_itemId=14250&g2_imageViewsIndex=1
[17:39:27] <Loetmichel> ?
[17:39:32] <CaptHindsight> acrylics bond well to acrylics
[17:39:43] <Loetmichel> CaptHindsight: more or less
[17:39:53] <CaptHindsight> solvent based acrylic paint vs waterborne
[17:39:58] <Loetmichel> grinding it with very fine sandpaper tends to help
[17:40:07] <mcfloppy> i mean like this: http://www.fdm-ware.de/front2/index.html
[17:40:16] <mcfloppy> okay
[17:40:17] <mcfloppy> ;)
[17:40:55] <Loetmichel> and BTW: "bastlerglas" is styro, not acrylics
[17:40:59] <Loetmichel> +l
[17:41:23] <mcfloppy> hrhr okay
[17:41:33] <CaptHindsight> any ink or paint with MEK will bite well into that
[17:42:12] <CaptHindsight> clean and prep well
[17:43:58] <CaptHindsight> hmm translating German to Turkish didn't help me
[17:45:10] <CaptHindsight> Hobbyists glass is also a thermoplastic, but it is unlike Plexiglas to "Polystyrene - PS".
[17:45:30] <Loetmichel> CaptHindsight: "bastlerglas" is a trade name for cheap polystyrol "glass" in german hardware superstores
[17:45:37] <CaptHindsight> hobbyist glass = bastlerglas
[17:46:55] <Gamma-X> anyone have or know a good place to get servos to replace nema 23 steppers? I dont like the thought of steppers after buyin them.... scares me that they can stall!
[17:47:09] <CaptHindsight> look for MEK on the paint label ingredients
[17:47:29] <CaptHindsight> http://en.wikipedia.org/wiki/Methyl_ethyl_ketone
[17:47:29] <Loetmichel> and unlike real acrylics its very low melting (bad to mill) and very easy to scratch
[17:47:46] <Loetmichel> CaptHindsight: you will have a problem to get that in german hardwaree stores
[17:48:11] <Loetmichel> german government is SO overprotective that they have ruled out even acetone in the hardware store
[17:48:19] <Gamma-X> or would it be better to just put encoders onto the steppers...
[17:48:21] <CaptHindsight> not straight MEK, just paint with it as an ingredient
[17:48:58] <Loetmichel> Gamma-X:as longh as you stay away from the max towque and the max speed you will be fine with steppers
[17:49:13] <Loetmichel> and they are reallly easy to drive for small money
[17:49:27] <Loetmichel> what kind of machine oyu want to drive with the motors?
[17:49:32] <Gamma-X> Loetmichel, im driving a rf45 that I want to be precise...
[17:49:41] <Loetmichel> bf45?
[17:49:52] <Loetmichel> that should be no problem
[17:50:02] <Loetmichel> i am driving a similar sized machine wit 1A steppers

[17:50:57] <Gamma-X> Loetmichel, what oz?
[17:51:18] <Loetmichel> dont know
[17:51:19] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12569
[17:51:53] <Loetmichel> but really small motors
[17:51:56] <Loetmichel> and old ones
[17:52:10] <Gamma-X> yeah thats not the same as rf 45 lol
[17:52:26] <zeeshan|2> rf45 is big :D
[17:52:27] <Gamma-X> my machine ways about 850 pnds
[17:52:41] <zeeshan|2> Gamma-X: PetefromTn_ in here had a rf45
[17:52:47] <zeeshan|2> but he was using servos
[17:53:02] <Gamma-X> this is correct, Yeah. Whats makin me want to go servo side...
[17:53:14] <zeeshan|2> i think the most common steppers are 800oz-in for the xy
[17:53:15] <zeeshan|2> and 1200 for z
[17:53:16] <Loetmichel> oh, sorry i assumed RF45 is a bf45 clone
[17:53:17] <Gamma-X> maby I can buy hybrid stepper drives and just add encoders...
[17:53:32] <Gamma-X> yeah i got 600 nema 23 steppers on xy
[17:54:40] <zeeshan|2> i think the choice between steppers and servos is easy
[17:54:47] <zeeshan|2> from my perspective, its just about how fast you want to go :P
[17:54:50] <Loetmichel> but still: steppers are ok as long as you dont go to the limit
[17:55:12] <Loetmichel> i.e: use only about 80% of the aviable torque and 80% of the max speed
[17:55:16] <Loetmichel> in your setup
[17:55:26] <Loetmichel> and think of the stall as safety feature ;)
[17:55:32] <Gamma-X> problem for me is pushing it to the limit... and to find out what the max is! haha
[17:55:43] <Loetmichel> thats easy
[17:55:51] <zeeshan|2> practically idon't think you can take advantage of the speeds of a servo on a rf45
[17:55:54] <zeeshan|2> its not rigid enough
[17:55:57] <Loetmichel> do empty runs and up the speed until it looses steps
[17:56:05] <zeeshan|2> g00 though, thats a diff story :P
[17:56:06] <Loetmichel> and then go to 80% of that at max

[18:06:10] -!- helix247__ has quit [Ping timeout: 264 seconds]
[18:06:15] <zeeshan|2> thats what i mean by taking advantage of the speed :)
[18:07:15] <PetefromTn_> You could NEVER mill aluminum like I can on the VMC but I certainly made a bunch of aluminum parts and with good feeds and speeds it cut pretty well actually.
[18:07:40] <zeeshan|2> thats why steppers are more than adequate :P
[18:07:43] <zeeshan|2> for a rf45
[18:07:45] <pcw_home> The leadshine hybrid drives are supposed to be quite good , not sure if you can just add encoders
[18:07:47] <pcw_home> to existing stepmotors or if there is something special about the motor/encoders that they use
[18:08:07] <PetefromTn_> Rapids were in the 250-300 range with it which was nice. Admittedly when I had it I did not know what the hell I was doing just yet so I always had the speeds cranked way down so I did not crash the shit out of it.
[18:08:22] <Gamma-X> pcw_home, i have extended shafts... adding an encoder is a seperate piece...
[18:08:52] <Gamma-X> PetefromTn_, thats what im affraid of haha
[18:09:13] <PetefromTn_> honestly some properly sized steppers should work fine for a machine like that but the head is a bitch.. It is pretty heavy for the size of the machine then you add in the belt driven spindel stuff and power drawbar and it only gets heavier.
[18:09:43] <zeeshan|2> when in doubt
[18:09:44] <zeeshan|2> MAD POWER!
[18:09:45] <zeeshan|2> :D
[18:10:42] <PetefromTn_> One nice thing about the XL belts I used on the servos was they actually acted as a fusible link. The one time I did crash the hell out of it when I was playing with my limit swtich buildup it went back to the column and the belt stripped the teeth off savine some serious damage to the ballscrew and motor pullies etc...

[18:13:05] <PetefromTn_> Unless there is some problem with the system.
[18:13:49] <PetefromTn_> Seriously just make some simple parts and check your dimensions, then take some more aggressive cuts and make them again and measure carefully. If the steppers are setup right there should really not be a problem.

[18:55:50] <Connor> make clean
[18:55:51] <Connor> make
[18:56:06] <Connor> recompiling whole tree.. again
[18:56:11] <zeeshan|2> rofl
[18:56:15] <zeeshan|2> so lame man!
[18:56:37] <PetefromTn_> Connor I am out in the shop now and the machine is on do you want me to hook it up to the router?
[18:56:40] <Connor> It's like, it's not even TRYING to compile it when I make the whole tree
[18:56:58] <Connor> PetefromTn_: Not until I can get this thing to compile fully on my workstation..
[18:56:59] <zeeshan|2> im gonan launch the computer
[18:57:02] <zeeshan|2> and we'll make this work!
[18:57:02] <PetefromTn_> I was just gonna try to make those damn vise jaws but realized my program for them is from the old control so won;t work.
[18:57:22] <Gamma-X> PetefromTn_, that hardinge you had was it cnc?

[19:01:00] <zeeshan|2> http://pastebin.com/MyH6wkvJ
[19:01:07] <zeeshan|2> compile it like that
[19:01:13] <zeeshan|2> how you were doing it yesterday

[19:02:00] <zeeshan|2> haha
[19:02:01] <zeeshan|2> wtf
[19:02:03] <Connor> when I change the refrence
[19:02:15] <Connor> by adding modbus/modbus.h instead of just modbus.h
[19:02:18] <Connor> I then get this..

[19:03:29] <Connor> if I do this..
[19:03:38] <Connor> comp --userspace wj200_vfd.comp
[19:03:40] <Connor> then

[19:05:46] Cylly is now known as Loetmichel
[19:05:53] <zeeshan|2> after you changed the submakefile
[19:05:59] <zeeshan|2> and did comp --userpsace etc
[19:06:02] <zeeshan|2> what error did you get?
[19:06:13] <zeeshan|2> can you post the output on pastebin
[19:06:19] <Connor> when I removed the ifeq ($(LIBMODBUS3_USABLE),yes)
[19:06:23] <Connor> from the Submake.. it compiles
[19:06:30] <Connor> BUT.. errors
[19:06:41] <zeeshan|2> i need to see the gcc command line options
[19:07:04] <Connor> Woha.. I have a file now..
[19:07:09] <Connor> was just a warning.
[19:07:24] <zeeshan|2> so the whole problem has been
[19:07:38] <Connor> so, what is LIBMODBUS3_USABLE ?
[19:07:38] <zeeshan|2> it was thinking LIBMODBUS3_USABLE was 'no'
[19:07:48] <zeeshan|2> and not compiling
[19:07:56] <Connor> yup
[19:08:01] <zeeshan|2> if you look in makefile.inc
[19:08:04] <zeeshan|2> line 140
[19:08:14] <zeeshan|2> HAVE_LIBMODBUS3 = yes LIBMODBUS_LIBS = -lmodbus LIBMODBUS_CFLAGS = -I/usr/include/modbus
[19:08:39] <zeeshan|2> i think when you do a configure, it it doesn't find libmodbus3
[19:08:49] <zeeshan|2> it sets that flag to 'no' and then it won't compile
[19:09:05] <Connor> it says.. HAVE_LIBMODBUS3 = yes
[19:09:10] <Connor> not HAVE_LIBMODBUS3 = yes
[19:09:19] <Connor> err.. not LIBMODBUS3_USABLE
[19:09:35] <zeeshan|2> sec i think they're related
[19:10:42] <zeeshan|2> honestly we can sit here and try to figure out this nonsense
[19:10:56] <zeeshan|2> just do the hack job
[19:11:00] <zeeshan|2> and keep that extra -I flag inthere
[19:11:06] <zeeshan|2> and delete the first if statement line :P
[19:11:39] <Connor> well.. the next step will be to compile this against the latest head version he has..
[19:12:03] <zeeshan|2> dude
[19:12:04] <Connor> which kinda sucks.
[19:12:11] <zeeshan|2> i think all you need is this to get the driver to compile
[19:13:25] <Connor> cd ..
[19:14:16] <zeeshan|2> gcc -Os -g -I. -I/usr/realtime-2.6.32-122-rtai/include -I. -I/usr/realtime-2.6.32-122-rtai/include -D_FORTIFY_SOURCE=0 -mhard-float -DRTAI=3 -fno-fast-math -mieee-fp -fno-unsafe-math-optimizations -DRTAPI -D_GNU_SOURCE -Drealtime -D__MODULE__ -I/usr/incnm
[19:14:20] <zeeshan|2> ^ ignore that
[19:14:21] <Connor> I'm thinking it also required me to add a line into the Makefile too.. to include the wj200_vfd sub dir
[19:14:24] <zeeshan|2> you need the script
[19:14:41] <Connor> What script ?
[19:14:44] <Connor> the comp stuff ?
[19:14:46] <zeeshan|2> the makefile script
[19:15:07] <Connor> Wish we could just convert Submake into a true Makefile
[19:15:09] <Connor> and be done with it.
[19:15:19] <zeeshan|2> hm.
[19:15:22] <zeeshan|2> i have a standalone make file
[19:15:27] <zeeshan|2> maybe it can compile it
[19:15:33] <zeeshan|2> wanna try?
[19:15:36] <Connor> sure.
[19:16:43] <zeeshan|2> the only ghetto thing about my make file is
[19:16:58] <zeeshan|2> you need modbus.c and modbus.h in the same directory as driver
[19:17:02] <zeeshan|2> when you're compiling
[19:17:16] <Connor> confirmed.. You also have to add the hal\user_comp\wj200_vfd to the main Makefile..
[19:17:26] <Connor> Why is that ?
[19:17:40] <zeeshan|2> cause it can't find the modbus stuff on its own :P
[19:17:54] <zeeshan|2> its a very basic makefile
[19:20:29] -!- thomaslindstr_m has quit [Ping timeout: 240 seconds]
[19:21:25] <zeeshan|2> just changing the make file
[19:21:28] <zeeshan|2> to make it work with your stuff
[19:21:36] <zeeshan|2> hook me up with the .c file name for the driver
[19:21:45] <Connor> wj200_vfd.comp
[19:21:52] <Connor> yes.. It's .comp
[19:21:52] <zeeshan|2> ugh
[19:21:54] <zeeshan|2> i forgot its a .comp
[19:21:56] <zeeshan|2> not gonna work.
[19:22:07] <Connor> why ?
[19:22:20] <Connor> I can get a C file by doing comp --userspace wj200_vfd.comp
[19:22:24] <zeeshan|2> cause when you're using comp
[19:22:47] <zeeshan|2> it simplifies the c code
[19:22:51] <zeeshan|2> so you don't have lines like:
[19:23:03] <zeeshan|2> // Make HAL pins retval = hal_pin_u32_newf(HAL_OUT, &(haldata->errorstatus), hal_comp_id, "%s.errorstatus", modname); if (retval!=0) goto out_closeHAL; retval = hal_pin_u32_newf(HAL_OUT, &(haldata->drivestatus), hal_comp_id, "%s.drivestatus", modname); if (retval!=0) goto out_closeHAL;
[19:23:16] <zeeshan|2> within your comp file
[19:23:22] <zeeshan|2> that's my understanding of it at least
[19:23:47] <zeeshan|2> you've got the comp compiling to give you a driver
[19:23:48] <zeeshan|2> so you're done :P
[19:24:19] <Connor> What a PITA
[19:24:40] <Connor> What sucks is.. it ALMOST works a a userspace module...
[19:24:48] <Connor> it DOES compile on my machine.. for some reason..
[19:24:58] <Connor> just could never get it to compile on his.
[19:25:03] <zeeshan|2> just loadusr -Wn VFD wj200_vfd -n VFD it
[19:25:03] <zeeshan|2> :P
[19:25:24] <Gamma-X> PetefromTn_, think encoders on steppers would do any good or no?
[19:25:40] <Connor> Gamma-X: No. Not worth it.
[19:25:53] <Connor> Just pick steppers strong enough to handle it and be done with it..
[19:25:55] <PetefromTn_> doubtful..
[19:25:57] <Connor> they get you nothign.
[19:26:11] * PetefromTn_ sighs..
[19:26:26] <Connor> All they do is send out a error if they miss a step.. can't compensate for it..
[19:26:28] * PetefromTn_ PetefromTn wants to stay outta the gutter...
[19:26:38] <Connor> PetefromTn_: Huh ?
[19:26:38] * PetefromTn_ and the Ghetto too...
[19:27:03] <Connor> PetefromTn_: Plug your machine in and let me see if I can compile this on your box.
[19:27:13] <PetefromTn_> Connor You got it sorted?
[19:27:20] <pcw_home> With hybrid drives you gain a lot, with standard step motor drives you only gain the ability to detect stalls
[19:27:22] <Connor> PetefromTn_: We'll see.
[19:27:22] <zeeshan|2> connor you know what'd be cool
[19:27:23] <Gamma-X> well im thinkin would linuxcnc be able to estop on a missed step!
[19:27:28] <zeeshan|2> is interfacing encoders with linuxcnc
[19:27:38] <zeeshan|2> and writing your own code to compensate for those missed steps
[19:27:47] <zeeshan|2> but then again i guess at the end of the day its reduntant
[19:27:52] <Gamma-X> thats what i was thinkin, didnt know if its been implimented
[19:27:53] <zeeshan|2> cause if you're missing steps, you've designed the system wrong
[19:27:58] <PetefromTn_> shouldn't be any missed step...
[19:27:58] <Connor> pcw_home: So, what exactly are "hybrid steppers"
[19:28:01] <pcw_home> if you stall its over
[19:28:15] <PetefromTn_> Connor Okay man gonna hook it up here gimme a minute.
[19:28:19] <pcw_home> no compenstaion possible
[19:28:40] <pcw_home> hybrid step drives run step motor like servos
[19:29:07] <syyl> compensating missing steps would be fun with two axis running at the same time :D
[19:29:53] <zeeshan|2> i really dont understand the point of closed loop system with a stepper
[19:30:05] <syyl> i run one with linear glas scales
[19:30:06] <syyl> !
[19:30:12] <Connor> pcw_home: You mean they run them in torque mode ? vs just step mode ?
[19:30:13] <syyl> thats more than cool ;)
[19:30:16] <pcw_home> better accuracy, no stallling
[19:30:20] -!- FreezingAlt [FreezingAlt!~FreezingC@] has joined #linuxcnc
[19:30:53] <pcw_home> They are run exactly like AC servos
[19:31:08] <Gamma-X> sounds very appealing...
[19:31:10] <Gamma-X> lol
[19:31:10] <zeeshan|2> ac servos don't stall?
[19:31:15] <pcw_home> so they also idle cool
[19:31:38] <Gamma-X> pcw_home, myne idle fine... with the newer drives they drop current to half.
[19:31:39] <pcw_home> since they only apply torque when needed
[19:31:56] <zeeshan|2> Gamma-X: you went with the 32 bit drivers? :D

[19:33:01] <zeeshan|2> connor don't get distracted please

[19:48:20] <zeeshan|2> nice
[19:48:34] <zeeshan|2> why arent you at the party
[19:48:36] <Connor> now, to pull down the src copy of the head he's running and compile it against that..
[19:48:36] <PetefromTn_> get the hell outta here seriously?
[19:49:22] <PetefromTn_> was not invited not that close with that particular neighbor...
[19:49:53] <Connor> how do you pull a src for head ?
[19:50:05] -!- patrickarlt has quit [Remote host closed the connection]
[19:50:40] <zeeshan|2> invite yourself in
[19:50:55] <PetefromTn_> I considered it LOL...
[19:51:24] <PetefromTn_> Connor Do you need me to do anything or just stand here looking stupid, I'm good at that.
[19:51:33] <Connor> I'm good.
[19:52:29] <PetefromTn_> zeeshan|2 Why did you tell us you were from Cyprus?
[19:52:43] <zeeshan|2> i didn't
[19:53:14] <PetefromTn_> is there another zeeshan?
[19:53:34] <archivist> the other is zaa...
[19:54:21] <archivist> at least my memory is still ok :)
[19:55:01] <archivist> Zaaarin
[19:55:27] <PetefromTn_> Oh is that what it is... I thought zeeshan was toying with us LOL...
[19:56:55] <zeeshan|2> haha
[19:57:16] <PetefromTn_> man I must be getting Oldstimers...
[19:57:42] <PetefromTn_> Connor WTF over?
[19:58:10] <Connor> PetefromTn_: Pulling down the latest src for head..
[19:58:26] <PetefromTn_> Okay...
[19:58:27] <Connor> then will compile against that.. but.. I'm going to have to run and get lunch in a bit.
[19:58:38] <Connor> want to start the compile before I do.
[19:58:51] <PetefromTn_> will I be able to run the machine while you are gone?
[19:59:07] <Connor> When to compile is over yes.
[19:59:18] <PetefromTn_> Should I close this window you made me open?
[19:59:26] <Connor> yea. you can
[19:59:56] <zeeshan|2> PetefromTn_: i love canada too much to leave
[20:00:00] <zeeshan|2> i go hiking up here
[20:00:01] <zeeshan|2> and do this:

[20:00:13] <zeeshan|2> eat wild blue berries :p
[20:00:19] <PetefromTn_> yeah but you freeze your ass off most of the year no?
[20:00:20] <zeeshan|2> one day i bet a bear is going to rape me
[20:00:25] <zeeshan|2> for eating his blue berries
[20:00:35] <zeeshan|2> about 5 months of the year are rough
[20:00:40] <zeeshan|2> but other than that, its all t-shirt weather
[20:00:51] <zeeshan|2> 10c = t-shirt weather for me :D
[20:01:01] <zeeshan|2> 50 f
[20:01:04] <PetefromTn_> I can't stand the cold here in Tennessee and want to move back to Florida and I am only two states away LOL...
[20:01:35] <Connor> okay. Compiling.
[20:01:51] <Connor> be back in a few.. it'll take a good 10-15 minutes for this to compile.
[20:01:54] <Connor> on the Atom
[20:02:07] <PetefromTn_> how come I can't see anything on it..
[20:02:08] <Connor> I wouldn't CNC anything while it is..
[20:02:16] <Connor> because. I'm doing it in the background.
[20:02:28] <PetefromTn_> oh a sneaky guy eh...?
[20:02:28] <Connor> remotely.
[20:02:56] <PetefromTn_> just so long as you don't take a big dump on my machine so it rapids off into oblivion when I push go...
[20:03:17] <PetefromTn_> Remember you don't live that far I can find ya...
[20:03:23] <zeeshan|2> lol
[20:03:37] <PetefromTn_> ;)
[20:03:39] <zeeshan|2> if he crashes your machine
[20:03:42] <zeeshan|2> there will be no cnc parts for him!
[20:03:50] <PetefromTn_> precisely...
[20:04:00] <zeeshan|2> he can't really run linuxcnc in the background anyway
[20:04:02] <Loetmichel> PetefromTn_: cold? in tennessee?
[20:04:03] <zeeshan|2> its just a console
[20:04:22] <Loetmichel> i thought that was next to texas?
[20:04:30] <PetefromTn_> Loetmichel Sure man was down to single digits here this winter several times...
[20:04:33] <Loetmichel> <- polishes his american geography
[20:04:57] <Loetmichel> single digits celsious or farenheit?
[20:05:03] <PetefromTn_> F
[20:05:15] <PetefromTn_> F as in freezin' my ass off...
[20:05:28] <Loetmichel> ah, only -15 Celsius
[20:05:34] <Loetmichel> thats easy going ;-)
[20:06:03] <PetefromTn_> Not when you grew up in South Florida and SO Cal..
[20:06:09] <Loetmichel> below minus 22 my car refuses to start.
[20:06:13] <zeeshan|2> dude i lived in the middle east (qatar)
[20:06:14] <Loetmichel> thats a PITA
[20:06:16] <zeeshan|2> for 12 years of my life
[20:06:22] <Loetmichel> but above that ist nice
[20:06:26] <zeeshan|2> it was 45c in the summer and 25 c in the winter
[20:06:34] <PetefromTn_> zeeshan|2 I'm sorry for you...
[20:06:46] <zeeshan|2> in 96 when i came to canada, i stepped outside and it was -25C
[20:06:47] <zeeshan|2> lol
[20:06:54] <zeeshan|2> rape
[20:07:17] <zeeshan|2> regardless, i love canada :D
[20:07:37] <PetefromTn_> I used to fly to Alaska a bunch when I was a navigator in the Coast Guard C-130's and I think I now know what cold is.... you can keep it.
[20:07:39] <Loetmichel> zeeshan|2: a friend of mine was in dheli for holidays
[20:07:41] <Loetmichel> monsun time
[20:07:54] <Loetmichel> it started rainig like hell
[20:07:56] <zeeshan|2> PetefromTn_: did you ever fly for NOAA?
[20:08:00] <zeeshan|2> they use c-130s!
[20:08:03] <Loetmichel> he got out ijn thsirt and shorts...
[20:08:06] <PetefromTn_> no but we worked with them a lot...
[20:08:08] <zeeshan|2> flying through hurricanes
[20:08:15] <Loetmichel> "Ahh, nice, a bit of a cooling down"
[20:08:23] <zeeshan|2> Loetmichel: haha
[20:08:28] <Loetmichel> ... it was still 20°c or so.
[20:08:45] <zeeshan|2> i still remember i was wearing 3 layers of clothes when i first came here

I need to configure the spindle VFD to accept it so I am reading about that now but do you have any pearls about how to setup hal for the modbus?
[21:22:02] <zeeshan|2> well
[21:22:13] <zeeshan|2> the first step is to make sure can load the usr component
[21:22:19] <zeeshan|2> *you can
[21:22:41] <zeeshan|2> do you know the name of the driver?
[21:22:48] <zeeshan|2> did it compile as wj2000_comp ?
[21:22:56] <zeeshan|2> in your custom.hal file add a line called:
[21:23:05] <PetefromTn_> jeez man I dunno he did it remotely and I could not see anything.
[21:23:30] <zeeshan|2> pop open a terminal
[21:23:51] <PetefromTn_> okay.
[21:24:15] <PetefromTn_> I just found the settings to change in the VFD to switch to modbus control...
[21:24:27] <PetefromTn_> terminal open
[21:24:29] <zeeshan|2> find / -name 'wj2000*'
[21:24:55] <zeeshan|2> you should find a file called wj2000_comp in like /usr/rtai something
[21:24:57] <zeeshan|2> i forgot the path

[21:25:24] <zeeshan|2> open up custom.hal for your linuxcnc config file

[21:26:26] <PetefromTn_> no I don't know about that.
[21:26:35] <zeeshan|2> wj200_comp
[21:26:36] <zeeshan|2> try it
[21:26:41] <zeeshan|2> worst comes to worst, linuxcnc wont start
[21:26:57] <zeeshan|2> and you know cause its cause it cant load the component cause the name is wrong :P
[21:27:06] <PetefromTn_> I thought you said he could not do it in comp...?

[21:27:37] <cheater> hi
[21:27:42] <zeeshan|2> PetefromTn_:
[21:27:43] <PetefromTn_> I need to do sudo etc.. and my passwork
[21:27:45] <zeeshan|2> just modify the hal file
[21:27:46] <zeeshan|2> :P
[21:27:55] <andypugh> With LinuxCNC running, open a Terminal window.
[21:28:02] <andypugh> Type halcmd -kf
[21:28:14] <cheater> i have a question not directly about cnc but very related, is it ok to ask here? it's about robotics and stuff
[21:28:15] <andypugh> That opens an interactive HAL session.
[21:28:25] <zeeshan|2> oh nice
[21:28:27] <zeeshan|2> i did not know that
[21:28:34] <zeeshan|2> do you have to be root to do that?
[21:29:03] <andypugh> Then type loadusr -Wn wj then press the tab key. If you are lucky then it will auto-complete to the right component name ;-)
[21:29:04] <PetefromTn_> how do I get permission in the terminal window to search the file?
[21:29:10] <zeeshan|2> PetefromTn_:
[21:29:14] <zeeshan|2> just add sudo in front of the find
[21:29:15] <cheater> PetefromTn_: sudo?

[21:31:40] <cheater> i'm about this likely to go back there right now: 0%.
[21:32:37] <PetefromTn_> So I type in sudo find / -name 'WJ200' then?
[21:32:44] <zeeshan|2> pete try
[21:33:12] <cheater> PetefromTn_: it's usually a good idea to add asterisks around the name. within the single-quotes (don't use double-quotes)
[21:33:23] <zeeshan|2> WJ200*
[21:33:24] <zeeshan|2> yea
[21:33:31] <cheater> and -iname is usually a good idea as well, because then case doesn't matter.

[21:34:40] <cheater> i'll ask my question. i'm trying to come up with something like a formal framework for describing movement of robots, and i'm wondering what the main concerns are when moving a robot. one is precision vs speed: i.e. how do you move precisely enough withough crawling all the way. another is not colliding with other things. another is not colliding with other things that are moving. is there anything ...
[21:34:46] <cheater> ... else i might be missing?
[21:34:50] <PetefromTn_> I typed in sudo find /-name '*WJ200*' and it did nothing...
[21:35:05] <cheater> PetefromTn_: you forgot a space between / and -.
[21:35:21] <zeeshan|2> you dont want a star in the front
[21:35:24] <zeeshan|2> it should be after
[21:35:32] <cheater> both sides are fine
[21:35:32] <zeeshan|2> your file name starts with wj for sure
[21:35:41] <zeeshan|2> wow my eyes are playing games
[21:35:44] <zeeshan|2> i didnt see the one after
[21:35:50] <zeeshan|2> PetefromTn_: change the WJ to wj
[21:36:16] <zeeshan|2> i have the source in front of me :P
[21:36:18] <cheater> zeeshan|2: what other things are difficult when moving a robot?
[21:36:24] <cheater> like an arm or a cnc mill or something
[21:36:47] <PetefromTn_> that does not work either I typed in sudo find / -name 'wj200*'
[21:37:16] <zeeshan|2> cheater sometimes when you're moving in space, one of the joints will not be physically able to move there
[21:37:16] <cheater> try: sudo find / -iname '*wj*200*'
[21:37:17] <zeeshan|2> and stall
[21:37:25] <cheater> zeeshan|2: aha
[21:37:31] <cheater> that's a good point
[21:37:33] <zeeshan|2> cheater i dont know how good youre in math
[21:37:40] <cheater> very good
[21:37:51] <zeeshan|2> but theres matrix math you can do to do checks
[21:37:54] <cheater> i know all about quarternions and shit
[21:37:55] <zeeshan|2> i haven't looked at it in a while
[21:38:00] <cheater> what matrix math
[21:38:08] <cheater> that's interesting
[21:38:24] <zeeshan|2> so you have some sort of interpolation you're going to use to move from one point to another point
[21:38:32] <PetefromTn_> you just hit enter after that right because it just goes back to the prompt on the next line...
[21:38:44] <zeeshan|2> you check each point along the path with your joint movement matrix and cartesian matrix
[21:38:48] <zeeshan|2> to check if you can physically make it there
[21:38:53] <cheater> PetefromTn_: what does this say: du -sh /
[21:38:57] <zeeshan|2> i suck with robots when it comes to hardware level
[21:39:35] <PetefromTn_> nothing just goes to next prompt..
[21:39:37] <zeeshan|2> cheater i bet if you ask a software engineer or computer scientist
[21:39:37] <cheater> zeeshan|2: can you find an article or book that describes this process exactly?
[21:39:48] <zeeshan|2> they know their shit =D
[21:39:53] <cheater> PetefromTn_: press ctrl-c twice. what do you get?
[21:39:55] <zeeshan|2> one sec, ill link you up with the book i used
[21:40:16] <andypugh> cheater You know about Denavit-Hartenberg parameters?
[21:40:18] <cheater> zeeshan|2: i'm a software engineer and computer scientist. there's a lot of ways to specialize though.

[21:41:18] <Swapper_> Anyone know if it is possible to compensate for a touchprobes runout in software? (comercial machines seems to have the function)
[21:41:23] <PetefromTn_> it says hello
[21:41:46] <cheater> andypugh: is that what zeeshan|2 has described?
[21:41:58] <cheater> PetefromTn_: ok, now type this: sudo du -sh /

[21:42:29] <PetefromTn_> it says permission denied.
[21:42:39] <zeeshan|2> we didnt use a book
[21:42:40] <zeeshan|2> unfrotunately
[21:42:44] <zeeshan|2> its a bunch of course notes
[21:42:49] <zeeshan|2> but in my search i did find a free book
[21:42:50] <zeeshan|2> http://www.cds.caltech.edu/~murray/books/MLS/pdf/mls94-complete.pdf
[21:43:06] <andypugh> cheater: This is the C-code that LinuxCNC uses to compute endpoint positons for an arbitrary serial robot using DH parameters. I can't follow it, but it sounds like you should be able to; http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=blob;f=src/emc/kinematics/genserkins.c;h=77f9f9718b0ada10d4b82100eb47a1ff956a6c04;hb=6170733672487665c3a27c4e9570f9ba03813216
[21:43:08] <zeeshan|2> chapter 3
[21:43:11] <zeeshan|2> 'manipulator kinematics'
[21:43:25] <PetefromTn_> jeez man I suck at this linuxCNC schtuff...
[21:43:53] <cheater> zeeshan|2: is what you're talking about the same as DH parameters?
[21:43:58] <andypugh> PetefromTn_: You seem OK at the "CNC" part, this is the Linux par
[21:44:11] <PetefromTn_> how do I get terminal sudo priveledges with password so I can try to search?
[21:44:26] <cheater> PetefromTn_: you need to enter your password.
[21:44:32] <PetefromTn_> how?
[21:44:36] <cheater> PetefromTn_: likely the same one you used to log in.
[21:44:40] <PetefromTn_> You have to get it to ask for it..
[21:44:49] <zeeshan|2> never heard of dh parameters before
[21:44:55] <cheater> by typing it in. sudo will ask for your password.
[21:45:37] <cheater> if it just says "permission denied" then your user is not in the "sudoers" group, which means it cannot run sudo at all. an alternative you could do would be to log in as root and run the commands this way.
[21:45:56] <zeeshan|2> or
[21:46:00] <zeeshan|2> you could guess the name
[21:46:09] <zeeshan|2> which im 95% sure is the right one
[21:46:10] <zeeshan|2> :P
[21:46:20] <cheater> one guy is american, one is chinese and one is indian?
[21:46:30] <PetefromTn_> man I know the name and password but I don't know how to get it to ask for it....so I can type it in.
[21:46:31] <cheater> sounds like most of my bad projects.
[21:46:35] <zeeshan|2> PetefromTn_:
[21:46:40] <zeeshan|2> asap you type sudo somecommand
[21:46:45] <zeeshan|2> it should automatically ask you for the password
[21:46:48] <zeeshan|2> if it doesnt
[21:46:51] <zeeshan|2> close the window and start again

[22:14:34] <zeeshan|2> :{
[22:14:48] <zeeshan|2> no trust!
[22:15:09] <andypugh> Actually, I think they are 2.5Nm. So you want a bit more than that for yours. I can't be bothered to convert to your stupid US units.
[22:15:11] <PetefromTn_> huh? Man I am over my head here just trying to do what you guys tell me...

[22:24:52] <PetefromTn_> now what?
[22:25:01] <zeeshan|2> pop up show hal config
[22:25:04] <Connor> bring up hal config
[22:25:07] <zeeshan|2> expand pins
[22:25:18] <zeeshan|2> and see if there is a wj200_comp there
[22:25:25] <Connor> hal pins are as follows, commanded_frequency, reverse, run, enable, is_running, is_atSpeed, is_ready, is_alarm, watchdog_out
[22:25:30] <Connor> wj200_vfd
[22:25:32] <Connor> he means
[22:25:39] <PetefromTn_> yeah there is...
[22:25:42] <zeeshan|2> yay
[22:25:45] <zeeshan|2> so it loaded up right
[22:26:00] <zeeshan|2> do you have it connected to the vfd?
[22:26:00] <PetefromTn_> there is a subset zero
[22:26:16] <PetefromTn_> yeah but I have not set the VFD settings yet for it.
[22:26:18] <Connor> right, because, you can have more than one VFD.
[22:26:55] <PetefromTn_> I got command freq,watchdog timeout,run,reverse,is running, is at speed,is alarm,enable.
[22:26:59] <zeeshan|2> sweet
[22:27:09] <zeeshan|2> before you assign any pins i'd persohnally test the driver
[22:27:12] <zeeshan|2> to see if it's communicating
[22:27:25] <zeeshan|2> the way i did it was i set up the vfd program to communicate using the right communication parameters
[22:27:42] <Connor> Yea. It has a paramater to tell it WHAT slave ID
[22:27:52] <Connor> in the hal component.
[22:27:53] <zeeshan|2> and then ran the vfd at a certain speed and 'watched' the the frequency
[22:28:10] <PetefromTn_> okay I am looking at page 333 of the pdf manual for the drive and there are the settings for modbus control.
[22:28:11] <zeeshan|2> by default it should be 0
[22:28:26] <zeeshan|2> connor do you know what the communication settings are

[22:33:06] <Connor> : When you change any of the parameters above, the inverter power must be

[22:33:11] <zeeshan|2> c074-> 0
[22:33:33] <zeeshan|2> c075 -> 1
[22:33:53] <zeeshan|2> c076 -> 02
[22:34:05] <zeeshan|2> (disable communication error select)
[22:34:12] <PetefromTn_> Frack I gotta restart the whole machine because I cannot open the electronics enclosure door due to the big switch..
[22:34:14] <zeeshan|2> make sure c077 -> 0
[22:34:48] <Connor> Headed to Home Depot to get some fittings and in shop. Text or Call me Cell if you need me PetefromTn_
[22:34:49] <zeeshan|2> c078 -> this is an important parameter
[22:35:21] <zeeshan|2> for now try c078 as '1'
[22:35:54] <PetefromTn_> zeeshan|2 Hang on a sec man I gotta redo some stuff here. Cya connor and thanks man..
[22:36:01] <zeeshan|2> PetefromTn_: np!
[22:38:58] <PetefromTn_> okay I am going to set C071-5, C072-1,c074-0,c075-1,c076-2,c077-0,and c078-1 correct?
[22:39:14] <zeeshan|2> lemme double cvheck
[22:40:16] <zeeshan|2> yea
[22:40:18] <zeeshan|2> thats correct
[22:40:24] <zeeshan|2> before changing c078 lemme know what its current value is
[22:40:34] <PetefromTn_> OK standby..
[22:41:26] <PetefromTn_> c078-0
[22:42:18] <zeeshan|2> okay
[22:42:24] <zeeshan|2> try leaving c078 as 0
[22:42:27] <zeeshan|2> and lets see if it works
[22:43:11] <PetefromTn_> okay all those settings were already set that way...
[22:43:26] <zeeshan|2> thats a good sign
[22:43:26] <zeeshan|2> lol
[22:43:40] <zeeshan|2> okay so launch up linuxcnc
[22:43:50] <PetefromTn_> it is already lauched..
[22:43:56] <PetefromTn_> launched.
[22:44:14] <zeeshan|2> so you didnt change any parameters right?
[22:44:17] <PetefromTn_> homing....
[22:44:23] <PetefromTn_> nope did not have to.
[22:44:26] <zeeshan|2> okay
[22:44:31] <zeeshan|2> cause otherwise youd have to reboot the driver
[22:44:33] <zeeshan|2> *drive
[22:44:35] FreezingAlt is now known as FreezingCold
[22:44:40] <zeeshan|2> click watch
[22:44:41] <zeeshan|2> and select:
[22:45:04] <PetefromTn_> okay so open halconfig?
[22:45:14] <zeeshan|2> expand the "wj200_comp" pin and select 'is running'
[22:45:21] <zeeshan|2> is_running

[22:45:35] <zeeshan|2> yes
[22:45:46] <PetefromTn_> okay..
[22:46:00] <zeeshan|2> it should be 'maroon'
[22:46:05] <PetefromTn_> it is..
[22:46:07] <zeeshan|2> and when you turn on your spindle
[22:46:10] <zeeshan|2> it should go green
[22:46:13] <zeeshan|2> check if that happens
[22:46:42] <PetefromTn_> nope...
[22:46:57] <zeeshan|2> well that sucks
[22:46:58] <zeeshan|2> lol
[22:47:07] <PetefromTn_> sure does...
[22:47:16] <zeeshan|2> set c078 to 1

[22:47:30] <PetefromTn_> Connor told me we did not need the ground pin to the vfd back there just the tx and rx is that true?
[22:47:40] <zeeshan|2> honestly i dont know if its true
[22:47:45] <zeeshan|2> i havec mine connected
[22:47:47] <zeeshan|2> just for the hell of it
[22:47:51] <zeeshan|2> its not like it can hurt
[22:48:05] <zeeshan|2> i dont know what it does
[22:48:10] <PetefromTn_> Okay I need to shut everything down now to change the setting and reboot right.
[22:48:20] <zeeshan|2> you're rebooting the vfd
[22:48:24] <zeeshan|2> so do it however you do that :P

[22:48:52] -!- asdfasd has quit [Ping timeout: 265 seconds]
[22:48:56] <PetefromTn_> so I have to shut it down completely and restart everything.
[22:48:57] <zeeshan|2> yea you're gonna need to disconnect from there then
[22:49:09] <PetefromTn_> I will change C078-1 then?
[22:49:14] <zeeshan|2> no
[22:49:16] <zeeshan|2> u wanna change it first
[22:49:18] <zeeshan|2> then reboot
[22:49:24] <PetefromTn_> yeah exactly right.
[22:49:36] <s1dev> all these mesa card SKUs are confusing
[22:49:37] <zeeshan|2> Instead of rebooting, turning ON/OFF of [18:33:08] <Connor> reset terminal works as same.
[22:49:47] <zeeshan|2> hm
[22:49:50] <zeeshan|2> just reboot
[22:49:51] <zeeshan|2> lol
[22:49:53] <zeeshan|2> easier prolly
[22:49:57] <s1dev> what's the difference between 5ixx and 7ixx
[22:50:11] <PetefromTn_> okay C078 is a time thing and there are three digits there ?
[22:51:49] <PetefromTn_> okay changed the zero to one restarting now..
[22:52:05] <zeeshan|2> okay
[22:52:44] <zeeshan|2> PetefromTn_: in linuxcnc
[22:52:48] <zeeshan|2> in hal config
[22:52:53] <zeeshan|2> just select all the wj200 pins
[22:53:03] <zeeshan|2> and see if any of them change when you start the spindle
[22:53:13] <zeeshan|2> we're just trying to see if there is communication happening

[22:55:32] <PetefromTn_> I went ahead and hooked up the ground to L on the terminals of the VFD.
[22:55:39] <PetefromTn_> homing...
[22:56:51] <PetefromTn_> okay clicked them all and started spindle and still maroon everywhere.
[22:57:04] <zeeshan|2> so its not communicating
[22:57:05] <zeeshan|2> :{
[22:57:28] <zeeshan|2> maybe something wrong with the wiring
[22:57:35] <zeeshan|2> correct me if im wrong
[22:57:48] <PetefromTn_> don
[22:57:53] <zeeshan|2> you've got the rs232 side of the adapter connected to your serial port
[22:57:56] -!- CHNCguy has quit [Quit: http://www.kiwiirc.com/ - A hand crafted IRC client]
[22:58:01] <zeeshan|2> and then youre using that terminal thing
[22:58:07] <zeeshan|2> to connect the d+ d- wires?
[22:58:22] <PetefromTn_> don't we need to set A oo1 and 002 to work?
[22:58:26] <zeeshan|2> no
[22:58:40] <zeeshan|2> that just lets modbus be able to make your vfd run or stop
[22:58:43] <zeeshan|2> or change the frequency of it
[22:58:51] <zeeshan|2> you don't wanna change that till you're certain you have communication
[22:58:53] <zeeshan|2> and nothing weird happens
[22:59:25] <PetefromTn_> yeah the adapter is plugged into the sole serial port and the wires are going from the little terminal block to Sn and Sp on the VFD..
[22:59:37] <zeeshan|2> sn goes to D+ on the terminal block?
[22:59:39] <zeeshan|2> er
[22:59:41] <zeeshan|2> sn goes to d-?
[22:59:45] <PetefromTn_> and now ground is going to L connor checked the ground with a voltmeter yesterday.
[22:59:59] <zeeshan|2> what a weird pin
[23:00:00] <zeeshan|2> to call ground
[23:00:02] <zeeshan|2> "L"
[23:00:02] <zeeshan|2> lol
[23:00:20] <zeeshan|2> make sure sn -> d-
[23:00:23] <zeeshan|2> and sp -> d+
[23:00:28] <PetefromTn_> I dunno I gotta take apart the pendant back to check it but he told me where to put the wires..
[23:01:09] <zeeshan|2> sorry what does the pendant have in it?
[23:01:18] <zeeshan|2> your computer?
[23:01:20] <PetefromTn_> the PC...
[23:01:22] <zeeshan|2> ah
[23:01:33] <zeeshan|2> im pretty sure the polarity matters
[23:02:10] <PetefromTn_> Okay then I better shut it all down and take it apart gimme a couple minutes here....Thanks for your help man.'

[23:10:33] <zeeshan|2> why do you call it tx+
[23:10:35] <zeeshan|2> and rx+

[23:25:53] <zeeshan|2> thats not wire right
[23:25:56] <zeeshan|2> *wired
[23:26:03] <zeeshan|2> the red wire
[23:26:07] <zeeshan|2> is that SN or SP?
[23:26:41] <s1dev> how big of a difference can a hardware step generator make over a software one
[23:26:48] <zeeshan|2> s1dev: huge one
[23:26:49] -!- arvidkahl_ has quit [Quit: Textual IRC Client: www.textualapp.com]
[23:26:51] <PetefromTn_> red is SP and white is SN
[23:26:58] <zeeshan|2> okay PetefromTn_
[23:27:12] <zeeshan|2> so the SP wire is wired right
[23:27:14] <zeeshan|2> it goes to D+.
[23:27:22] <zeeshan|2> the white one should be going to D-
[23:27:26] <zeeshan|2> (TX-)
[23:27:30] <zeeshan|2> move that wire there please
[23:27:31] <PetefromTn_> okay standby..
[23:27:38] <s1dev> for what properties? speed? accuracy?
[23:27:50] <zeeshan|2> s1dev: so you can actually generate the steps you need
[23:27:56] <zeeshan|2> and arent limited to parallel port speeds
[23:28:04] <zeeshan|2> on a stepper system i think its pretty pointless
[23:28:15] <zeeshan|2> a parallel port system works more than enough :P
[23:28:37] <zeeshan|2> PetefromTn_: just do double check
[23:28:39] <s1dev> so I can pretty much just plug my stepper drivers into my parallel port and be fine?
[23:28:39] <zeeshan|2> the ground wire you added
[23:28:48] <zeeshan|2> it actually goes to the terminal that has "GND"
[23:28:49] <PetefromTn_> Okay I got the white wire to the first pin and the red wire where it was..
[23:28:51] <zeeshan|2> written under it
[23:28:52] <zeeshan|2> right?
[23:29:10] <zeeshan|2> s1dev: yea
[23:29:17] <zeeshan|2> obviously through a breakout board that is isolated
[23:29:26] <zeeshan|2> don't burn a parallel port :P
[23:29:32] <PetefromTn_> yeah and so does the shielding...
[23:29:36] <s1dev> and where do I find such a breakout board?
[23:29:40] <zeeshan|2> s1dev: what inches per minute do you want to run?
[23:29:49] <zeeshan|2> PetefromTn_: you and your shielding
[23:29:50] <zeeshan|2> lol
[23:29:57] <zeeshan|2> PetefromTn_: should work now
[23:29:57] <PetefromTn_> ;)
[23:30:05] <PetefromTn_> Okay so fire it up?
[23:30:09] <zeeshan|2> fire up vfd
[23:30:10] <zeeshan|2> and restart linuxcnc
[23:30:12] <s1dev> whatever is cheapest, it's for a lathe
[23:30:13] <zeeshan|2> just to be sure
[23:30:22] <zeeshan|2> s1dev: what size lathe?
[23:30:29] <zeeshan|2> for my lathe i only want to run 100ipm
[23:30:33] <s1dev> 11" swing 36" bed
[23:30:35] <zeeshan|2> so i can easily run that through a parallel port
[23:30:39] <zeeshan|2> mines a 12x36
[23:30:47] <zeeshan|2> i have 1200oz-in steppers
[23:30:56] <zeeshan|2> and im using a pbx-rf probotix breakout board
[23:31:03] <s1dev> are you using direct drive?
[23:31:06] <zeeshan|2> yes
[23:31:22] <s1dev> what power supply are you using?
[23:31:28] <zeeshan|2> i kinda went overkill
[23:31:29] <PetefromTn_> okay powered up and homing...
[23:31:36] <zeeshan|2> im using the 72V 8A smps power supplies
[23:31:38] <zeeshan|2> through automation technologies
[23:31:45] <zeeshan|2> if i could do it again, i'd get the torodial one.
[23:31:47] <zeeshan|2> so you only need 1.

[23:32:03] <zeeshan|2> thats my setup s1dev
[23:32:39] <s1dev> thanks, are those the 2M524 or TBsomethingorother stepper drivers?
[23:32:47] <zeeshan|2> kl-8070d
[23:32:49] <PetefromTn_> Damn man still all maroon..
[23:32:53] <zeeshan|2> PetefromTn_:
[23:32:54] <zeeshan|2> dont lie
[23:32:55] <zeeshan|2> cmon man!
[23:32:58] <zeeshan|2> seriously?
[23:32:59] <s1dev> is that what you would suggest?
[23:33:05] <PetefromTn_> should I shut it down and change the C078 ?
[23:33:08] <zeeshan|2> s1dev: to drive the 1200oz steppers yea
[23:33:12] <zeeshan|2> PetefromTn_: yea set it back to 0
[23:33:43] <s1dev> I plan on getting the 1600oz stepper since it's only a bit more
[23:33:55] <zeeshan|2> you dont need it
[23:33:56] <zeeshan|2> man
[23:34:00] <zeeshan|2> with our size lathes
[23:34:05] <zeeshan|2> you can easily run 500oz-in steppers
[23:34:11] <zeeshan|2> 1200oz-in is overkill
[23:34:11] <zeeshan|2> lol
[23:34:26] <zeeshan|2> but if you go with 1600oz-in you cant use kl8070d drivers
[23:34:32] <zeeshan|2> 1600oz-in draw 8.8A
[23:34:39] <zeeshan|2> you're gonna have to use the other drives they sell
[23:34:45] <zeeshan|2> and you're going to need a bigger power supply ;p
[23:34:54] <s1dev> I can just run them underrated, correct?
[23:34:59] <zeeshan|2> you can
[23:35:01] <zeeshan|2> but then whats the point :P
[23:35:15] <zeeshan|2> arent the 1600oz steppers 30$ more each?
[23:35:19] <zeeshan|2> save yourself 60$ :P
[23:35:32] <s1dev> about $40 more over 3 motors
[23:35:38] -!- CHNCguy has quit [Quit: http://www.kiwiirc.com/ - A hand crafted IRC client]
[23:35:38] <zeeshan|2> why 3
[23:35:47] <s1dev> because that's the smallest I can get them
[23:35:51] <s1dev> I'll sell off one
[23:36:14] <zeeshan|2> sell it to me cheap
[23:36:15] <zeeshan|2> :)
[23:36:23] <s1dev> sure why not
[23:36:25] <zeeshan|2> haha
[23:36:31] * s1dev is srs
[23:36:41] <zeeshan|2> i need 2 1200oz-in for the mill
[23:36:44] <zeeshan|2> and 1 2480oz-in
[23:36:57] <zeeshan|2> but why dont you save yourself the money
[23:36:59] <zeeshan|2> and just buy 2?
[23:37:02] <CaptHindsight> I'll pay whatever he pays X 50%!
[23:37:05] <zeeshan|2> if youre buying from automation technologies
[23:37:07] <zeeshan|2> they'll sell you 2
[23:37:10] <zeeshan|2> it works out to be cheaper
[23:37:14] <PetefromTn_> Damn man it is still all maroon.
[23:37:21] <zeeshan|2> PetefromTn_:
[23:37:25] <zeeshan|2> so you rebooted your linuxcnc

[23:42:19] <s1dev> because I can get them for $90/ea
[23:42:29] <s1dev> and mainly because I have no idea how big I need
[23:42:38] <zeeshan|2> go with 1600
[23:42:38] <zeeshan|2> :P

[23:42:44] <zeeshan|2> do it like a boss!
[23:42:51] <s1dev> that's the though
[23:42:53] <s1dev> *thought
[23:43:00] <zeeshan|2> PetefromTn_:
[23:43:00] <Gamma-X> doesnt it seem WAY overkill though? lol especiially on a lathe
[23:43:04] <zeeshan|2> interesting its a different terminal block
[23:43:08] <zeeshan|2> you have rx+ and r-
[23:43:16] <Gamma-X> PetefromTn_, I have same thing! lol
[23:43:21] <zeeshan|2> but anyway, d- and d+ is where your wires are supposed to be
[23:43:23] <PetefromTn_> you can easily get LESS performance from oversized steppers than with smaller ones if not setup right.
[23:43:56] <s1dev> Gamma-X: I'm not sure how much force is needed in the first place, I'd rather have too much torque than too little
[23:44:09] <zeeshan|2> s1dev: you havent used your lathe manually
[23:44:14] <zeeshan|2> take a cut in some steel
[23:44:18] <Gamma-X> s1dev, well the z-y on a lathe doesnt need that much.
[23:44:18] <zeeshan|2> and youll get a feeling quite fast ;p
[23:44:33] <s1dev> but those are with the hand wheel which is geared
[23:44:36] -!- skorasaurus has quit [Read error: Operation timed out]
[23:44:44] <zeeshan|2> PetefromTn_: your wiring is correct
[23:44:44] <zeeshan|2> =/
[23:44:51] <zeeshan|2> i'm wondering now whats going on
[23:45:07] <zeeshan|2> is your serial port working?
[23:45:11] <s1dev> I'd want to drive it with the drive screw
[23:45:32] <PetefromTn_> We have the wiring setup using the 0-10v into the mesa 7i77 now AND the modbus too. is that okay?
[23:45:50] <zeeshan|2> yea thats fine
[23:45:55] <zeeshan|2> shouldnt interfere with communication
[23:46:05] <zeeshan|2> honestly theres 3 things i can think of thats wrong
[23:46:12] <PetefromTn_> how can I tell?
[23:46:13] <zeeshan|2> 1. your converter doesnt work
[23:46:19] <zeeshan|2> 2. serial port isnt working on computer
[23:46:25] <zeeshan|2> 3. the driver is messed up
[23:46:33] <CaptHindsight> humble_sea_bass: http://www.quantumrlv.com.au/ Development of EAP actuators for Braille Cells as an aid to visually impaired and blind.
[23:46:48] <Gamma-X> s1dev, id think 900ounce steppers would work a charm.
[23:46:57] <s1dev> would I have to gear them?
[23:47:09] <PetefromTn_> Converter is brand new, No idea if serial port is working never used it before, No clue...
[23:47:21] <zeeshan|2> i dont know how you would test a serial port
[23:47:47] <PetefromTn_> Atom board is brand new never used for anything but this...
[23:47:52] <zeeshan|2> PetefromTn_:
[23:47:55] <zeeshan|2> type dmesg | grep tty
[23:48:01] <zeeshan|2> in a terminal
[23:48:08] <Gamma-X> s1 well think of it like this... a mill's xy would have much more force on them... and a lathe is just moving the tool... the z is usually bigger on a mill for the weight of a head and such.
[23:48:26] <zeeshan|2> does it say something like ttyS0 ttyS1 etc?
[23:48:33] <Gamma-X> s1dev, so in resepct to that, if you have ball screws I would think direct drive would be fine with 900
[23:48:47] <PetefromTn_> How do you make the line?
[23:49:00] <zeeshan|2> on my keybaord its
[23:49:01] <zeeshan|2> shift \
[23:49:05] <humble_sea_bass> wel[
[23:49:05] <zeeshan|2> might be different on yours
[23:49:15] <PetefromTn_> nevermind I got it
[23:49:24] <PetefromTn_> What do you need to know?

[23:49:38] <zeeshan|2> does it say something like
[23:49:40] <s1dev> that's still NEMA34 territory right?
[23:49:42] <zeeshan|2> ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
[23:49:52] <PetefromTn_> says consode TTY0 enabled.
[23:49:56] <zeeshan|2> what do you see "ttys0
[23:50:00] <zeeshan|2> do you see a ttys1?
[23:50:21] <PetefromTn_> yeah it says that. And I see ttsy1
[23:50:30] <zeeshan|2> type setserial -g /dev/ttyS[0123]
[23:50:41] <zeeshan|2> and see if it reports back with IRQ's for each port

[23:52:07] <PetefromTn_> its says the program setserial is currently not installed.
[23:52:24] <zeeshan|2> fak it
[23:52:24] <humble_sea_bass> i can't find that paper from quantum Tech
[23:52:48] <PetefromTn_> should I install it?
[23:52:51] <zeeshan|2> nah
[23:52:57] <zeeshan|2> do you see a ttyS2?
[23:53:00] <zeeshan|2> when you did that dmesg thing
[23:53:09] -!- Einar has quit [Ping timeout: 265 seconds]
[23:53:13] <PetefromTn_> no just zero and 1
[23:53:21] <zeeshan|2> so that means your atom has 2 serial ports
[23:53:31] <zeeshan|2> maybe it's connected to serial port 1
[23:53:34] <zeeshan|2> and not serial port 0
[23:53:39] <PetefromTn_> no just one port..
[23:53:52] <Gamma-X> s1dev, yup
[23:53:58] <zeeshan|2> whats the model for your motherboard
[23:54:20] <s1dev> lol, I can't find 900oz steppers for cheaper than the 1600oz steppers
[23:54:41] <CaptHindsight> whats the smallest machine ever controlled by Linuxcnc?

[23:57:15] <Gamma-X> s1dev, link to your steppers?
[23:57:26] <s1dev> the 1200 or the 1600oz ones?
[23:57:32] <PetefromTn_> I dunno it is an Intel board mini ITX with D525..

[23:57:47] <s1dev> first is the 1600oz
[23:58:07] <PetefromTn_> that looks like it..
[23:58:17] <CaptHindsight> zeeshan|2: there were several mini-itx boards with names the same as the cpu
[23:58:31] <zeeshan|2> ah
[23:58:34] <zeeshan|2> well its got 2 serial ports
[23:58:48] <zeeshan|2> one has a db9 connector
[23:58:55] <zeeshan|2> the toher one has pins to connect a header to
[23:59:09] <zeeshan|2> i'm not sure which one is port #0 and port #1
[23:59:14] <PetefromTn_> okay then yeah it is the db9 of course we are hooking to here.
[23:59:40] <Gamma-X> s1 id get those 1200 ones and the same drives I have.
