[06:47:54] <Mr_Mayhem> Hmm, how to add the A axis info in the ini for Pncconf for a Mesa 7I76?
[06:48:38] <Mr_Mayhem> I have the X,Y, and Z axis working, but now for A axis...
[06:51:23] <jesseg> hahahaha
[06:51:37] <jesseg> Mr_Mayhem, Do you want A to be angular or linear?
[06:51:46] <Mr_Mayhem> Angular, please.
[06:51:52] <jesseg> Oh that's easy then
[06:52:43] <jesseg> I don't know a lot about it, but it does come with several example ini files which can give example of 3 linear and 1 angular
[06:52:51] <Mr_Mayhem> I have the MESA_CNC_MACHINE.ini open in front of me. Was gonna copy the z info, but its angular, not linear.
[06:53:08] <Mr_Mayhem> oh, ok.
[06:54:01] <jesseg> The entry in the ini file for angular is similar to linear, but the type is set to angular and of course it is scaled in degrees.
[06:54:25] <Mr_Mayhem> I guess I have to find the example so my syntax is right at least. Then tweak the numbers. Hey I don't even have the drive yet, but I figure I should get familiar and see if I can move a motor. The easy example dosent do the A.
[06:54:32] <jesseg> Actually, I believe the stepconf helper app has a ready made profile for 3 linear and one angular
[06:55:01] <Mr_Mayhem> Ok Angular instead of Linear for TYPE and degrees instead of units.
[06:55:16] <jesseg> yeah
[06:56:01] <Mr_Mayhem> I tried the easy one that runs via script and it would not give me the next button for after entering the A data in Pncconf
[06:56:35] <Mr_Mayhem> So I ran into the issue. So what file do I need to examine for an example, hmmm.
[06:57:12] <jesseg> let me poke around a bit
[06:57:25] -!- terabyte- [terabyte-!~terabyte@c-76-18-21-170.hsd1.fl.comcast.net] has parted #linuxcnc
[06:57:59] <Mr_Mayhem> Hey, thanks. Nice to have help, I appreciate.
[07:00:37] <jesseg> Did you try running stepconf? That's different than pnconf
[07:04:10] <Mr_Mayhem> Naa, I used that for my old parallel port setup when I began my cnc adventure. Now I have the Mesa 5I25 and the 7I26 matching daughterboard. I ran a script I found in the Linuxcnc forums here to prep the pnconf app because it dosent have this card's directories and/or files yet on the original linuxcnc image. So the script fixes that issue so you can then run pnconfig. http://www.gnipsel.co
[07:04:10] <Mr_Mayhem> m/linuxcnc/configs/pncconf-7i76.html
[07:06:41] <jesseg> Anyway, I used the stepconf to generate a 3 linear and 1 angular .ini file.
[07:07:20] <jesseg> If you can find the Sherline4Axis_inch.ini file on your hard drive in the example configs folder, it gives example of 3 linear and 1 angular.
[07:07:27] <Mr_Mayhem> When I ran pncconf I can get to the last step for 3 axis, but not 4. When I tried to set XYZA instead of simple XYZ axis, I get stuck because the next button is not enabled, so I can not proceed to apply and save the config. I figure I have to manually edit something in the ini and or hal config files.
[07:08:06] <jesseg> In particular, you need the following:
[07:08:09] <jesseg> AXES=4
[07:08:17] <Mr_Mayhem> OK I will have a look. Then I need to see, how do the hal files get made? Do I just reopen pncconf and roll through it and save? Will the ini be enough for that stunt?
[07:08:28] <jesseg> COORDINATES = X Y Z A
[07:09:04] <jesseg> then your fourth axis needs to start with
[07:09:07] <jesseg> [AXIS_3]
[07:09:07] <jesseg> TYPE = ANGULAR
[07:09:26] <jesseg> and you need the rest of the calibration stuff for that axis there too.
[07:09:31] <Mr_Mayhem> ok coordinates, got it. Axis_3 let me catch up hehe.
[07:10:01] <jesseg> and your halfile needs to be an xyza file too
[07:10:42] <Mr_Mayhem> ok, I think I hit all but the hal.
[07:11:28] <jesseg> anyway, I've said more than I know now.. hopefully someone who knows this stuff will be along:P
[07:11:31] <Mr_Mayhem> Should I just copy over z and edit your mentioned elements, or only include your mentioned elements?
[07:11:46] <jesseg> I'm still in the beginning stages - with a step & dir on printer port and little sherline :P
[07:11:47] <Mr_Mayhem> for Axis_3
[07:11:53] <Mr_Mayhem> hehe
[07:11:57] <Mr_Mayhem> I am also.
[07:12:03] -!- Nekosan has quit [Quit: later folks...]
[07:12:14] <jesseg> Let me paste all of this example A/Axis_3
[07:12:17] <Mr_Mayhem> But I am comfortable farting with the settings, no biggie.
[07:12:22] <Mr_Mayhem> ok
[07:12:29] <jesseg> [AXIS_3]
[07:12:30] <jesseg> TYPE = ANGULAR
[07:12:30] <jesseg> HOME = 0.0
[07:12:30] <jesseg> MAX_VELOCITY = 25.0
[07:12:30] <jesseg> MAX_ACCELERATION = 160.0
[07:12:30] <jesseg> STEPGEN_MAXVEL = 26.0
[07:12:32] <jesseg> STEPGEN_MAXACCEL = 196.0
[07:12:34] <jesseg> BACKLASH = 0.000
[07:12:36] <jesseg> INPUT_SCALE = 160
[07:12:38] <jesseg> MIN_LIMIT = -36000.0
[07:12:40] <jesseg> MAX_LIMIT = 36000.0
[07:12:42] <jesseg> FERROR = 5.0
[07:12:46] <jesseg> MIN_FERROR = 1.0
[07:12:48] <jesseg> HOME_OFFSET = 0.0
[07:12:50] <jesseg> HOME_SEARCH_VEL = 0.0
[07:12:52] <jesseg> HOME_LATCH_VEL = 0.0
[07:12:54] <jesseg> HOME_USE_INDEX = NO
[07:12:56] <jesseg> HOME_IGNORE_LIMITS = NO
[07:13:22] <jesseg> Let me know when you see <<THIS line and I'll know all my pasting made it through :P
[07:13:43] <Mr_Mayhem> I see the << line.
[07:13:48] <jesseg> That's just the fourth axis from the example sherline -- but it gives you an idea anyway.
[07:14:42] <Mr_Mayhem> Ok, well that's a good start. I notice some differences. I will try to make sense of it. I notice the 360 stuff for angles, ok.
[07:15:18] <jesseg> yeah, it looks like that sample only allows maximum 100 turns in either direction.
[07:16:07] <jesseg> Oh, up in the [TRAJ] section, you also need ANGULAR_UNITS = degree
[07:16:25] <jesseg> unless you wish to use metric angular units or something ha ha (or radians or gradians?)
[07:16:37] <Mr_Mayhem> hehe
[07:17:32] <Mr_Mayhem> I will never learn trig the way they usually teach it, ha. Ok let me do the TRAJ line.
[07:17:55] -!- WalterN_bed has quit [Ping timeout: 245 seconds]
[07:18:19] <jesseg> The AXES= and COORDINATES= lines also both go in the [TRAJ] section. Forgot to mention that.
[07:19:05] <jesseg> And if you have a [HAL] section in your ini file, it probably needs to point to some .hal file which has "xyza" in its name.
[07:19:11] <Mr_Mayhem> ok, well that's no big deal it turns out, they are already there for me too.
[07:19:11] <jesseg> an5yway, past my bedtime. Have fun!

[13:43:48] <rob_h> any one in the UK thinking of going to the Mach2014 show at the NEC?? how about you archivist
[13:43:59] <archivist> I usually go
[13:44:25] <rob_h> should see if there afew others i guess, if we agree on a day could meet up for a coffie like
[13:44:31] <archivist> its a bloody long walk though

[13:45:42] <rob_h> you can fit the NEC inside the hannover show ground easy i would way.
[13:46:17] <rob_h> it was nice to see the things you dont see here also, like alot of german made cnc machines

[13:47:47] <rob_h> still a space issue haha but this christmas things are getting moves around and in it comes with barfeed
[13:47:54] <rob_h> i have a stack of work lined up for it
[13:48:39] <rob_h> i have sorted alot of collets for spindle and guide bush's out now also, and tooling

[13:48:53] <rob_h> or making parts
[13:49:30] <rob_h> just been bussy chaning old DC motors on a superslant to new AC motors... also had to fit a new ballscrew on the X as it was well pasted its date
[13:49:38] <archivist> I got a spare spindle that may fit my sliding head off fleabay the other week
[13:49:43] <rob_h> nice new C3 screw and nut
[13:50:22] <rob_h> nice, sub spindle for you too then
[13:50:48] <rob_h> i have had the citizen running and stuff to have a play as one does :) and fixed all its Oil restrictors as most did not work
[13:50:49] <archivist> no it is the main spindle fr a later model
[13:51:35] <archivist> 131054656410

[15:40:35] <CHNCguy> Anyone know how to load themes?
[15:40:42] <CHNCguy> for a lathe?
[15:41:14] <archivist> themes?
[15:41:46] <CHNCguy> check this out http://www.youtube.com/watch?v=fkOJhT69WEc
[15:41:53] <CHNCguy> he has lathe themes
[15:41:57] <CHNCguy> he calls it "themes"
[15:42:04] <CHNCguy> its subroutines but with graphics
[15:43:11] <archivist> I have to restart firefox to view videos
[15:44:21] <CHNCguy> ohhh
[15:44:55] <archivist> there is a link to the forum on that video, did you follow it
[15:45:34] <CHNCguy> i did, but is was very confusing, did you get to figure it out?
[15:45:59] <archivist> I have never bothered for my lathe
[15:46:12] <CaptHindsight> CHNCguy: it looks like he's added some features to Linuxcnc that he hasn't advertised much
[15:46:34] <CHNCguy> i noticed that also, because he is the only one who has something like this...
[15:47:36] <archivist> so far in here I have only seen ngcgui discussed
[15:48:03] <micges> CHNCguy: there is info about installing here :https://github.com/cnc-club/linuxcnc-features
[15:48:17] <ReadError> is there any way to create a system event when a toolpath finishes?
[15:48:31] <ReadError> that sure would be nice
[15:49:05] <micges> what kind of event?
[15:49:11] <archivist> ReadError, a custom mcode
[15:49:15] <ReadError> maybe execute a shell script
[15:49:24] <ReadError> see my machine is in the basement
[15:49:31] <ReadError> and its cold there, so i do other things
[15:49:39] <ReadError> i could use a shell script + mutt
[15:49:41] <CaptHindsight> wake dog to change part
[15:49:43] <ReadError> send an email
[15:49:54] <ReadError> to local smtp server
[15:49:59] <ReadError> which would buzz my phone
[15:50:26] <micges> you can create say M100 with shell script inside in you nc_files directory
[15:50:51] <micges> and add M100 just before M2
[15:51:24] <ReadError> hm just need to use some awk or something to append this to all my files
[15:52:31] <archivist> sed
[15:52:43] <ReadError> derp yea
[15:53:13] <CHNCguy> quick question, when I set up the i/o for a 3rd axis being the turret, would it be a axis, or custom signals? I am using 5i25 and 7i76
[15:59:23] -!- kwallace has quit [Ping timeout: 260 seconds]
[16:01:07] <pcw_home> Custom signals, its not really an axis
[16:04:22] <CHNCguy> so would I just say the turret is the A axis?
[16:04:34] <pcw_home> no
[16:04:44] <pcw_home> its not an axis

[16:11:41] <pcw_home> with most toolchangers you have wandered into the custom comp area
[16:14:56] <pcw_home> There may be some other people with CHNC/LinuxCNC retrofits that can guide you,

[16:42:30] <JT-Shop> CHNCguy, take a look at the stepper winder on this page Maximum Workpiece Thickness: 22 Ga.
[16:42:46] <JT-Shop> http://gnipsel.com/linuxcnc/index.html

[16:46:29] <archivist> I thought you would be pointing him at some classicladder for the turret, I am not sure if he will get that
[16:50:03] <jthornton> actually rob_h has done what he is thinking about doing
[16:50:34] <CHNCguy> sorry im back ;)
[16:50:46] <CHNCguy> Hey archivist I do, but he uses an air motor setup
[16:50:48] <archivist> how many chncs have been done now
[16:51:40] <CHNCguy> lots probably, I did speak to Rob_h he used a servo also, but I have yet to hear back about his set up and how he using his mesa cards
[16:52:24] <archivist> he was in here this morning
[16:54:08] <CHNCguy> so what is the smart serial 0 in the mesa0 config page? is that just the pinouts on the 7i76?
[16:56:02] <pcw_home> sserial0 runs the digital I/O section of the 7I76
[16:56:16] <pcw_home> sserial1 is the expansion port
[16:56:34] <pcw_home> (with normal firmware and 7I76 on P3)
[17:00:18] <CHNCguy> thank you
[17:01:26] <CHNCguy> if im using a stepper drive, yet cant find the step on time, space, hold, and setup figures, do I just use 10000? Will this affect speed?
[17:03:18] <pcw_home> If you dont know (and they are recent drives) I would use something like 5000/5000/10000/10000
[17:03:34] <pcw_home> (that will limit you to 100 KHz max)
[17:04:10] -!- dgarr has quit [Quit: Leaving.]
[17:04:29] <pcw_home> actually a little less than 100 KHz since you need some overhead
[17:06:11] <pcw_home> best to find the specs (rather than find them by having it malfunction in the middle of something on a particularly warm or cold day)
[17:06:20] <CHNCguy> thanks pcw
[17:06:36] <CHNCguy> well the drives are hbs86 hybrid servo drives
[17:06:55] <CHNCguy> the8
[17:07:00] <CHNCguy> they*
[17:07:15] <pcw_home> They must have a manual of some kind
[17:07:21] <CHNCguy> did see squat in their documentation about the timing pulses

[17:07:49] <CHNCguy> http://www.leadshine.com/UploadFile/Down/HBS86d.pdf
[17:08:08] <CHNCguy> says input freq 200k
[17:08:14] -!- Tom_itx has quit [Ping timeout: 240 seconds]
[17:09:51] <pcw_home> so you could try 2500,2500,10000,10000
[17:11:18] <CHNCguy> k thanks
[17:11:45] <pcw_home> (the setup and hold time will have very little influence on performance but the maximum step rate is 1/(StepTime+StepSpace))
[17:12:24] -!- ck1 [ck1!~ck@p5DCE75BA.dip0.t-ipconnect.de] has joined #linuxcnc
[17:13:17] <CHNCguy> so the lower the step time and space the faster I can push it?
[17:13:36] -!- thomaslindstr_m has quit [Quit: Leaving...]
[17:13:54] <archivist> stepper drives are limited b the motor
[17:14:50] <pcw_home> Yes you max RPM will be limited by the torque fall-off of the motor/drive combination
[17:15:37] -!- flughafen has quit [Ping timeout: 272 seconds]
[17:16:05] <pcw_home> (running at close to the maximum drive voltage will get the most speed out of the motors)

[17:16:56] <CHNCguy> Will they run with the test/tune axis button?

[17:51:51] <jthornton> CHNCguy, http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Drive_Timing
[17:51:55] <IchGuckLive> thats all you need
[17:52:01] <jthornton> your leadshine is listed on that page
[17:52:10] <TangentAudio> stepgen pin assignment behavior seems to have changed in 2.6.. in 2.5.x stepgens used to only have step and dir pins and the rest were left as gpio... in 2.6.x (latest from git) it seems the extra pins show up as "Table2Pin", "Table3Pin" etc.
[17:52:24] <IchGuckLive> if its a M542 go for 5000 5000 20000 20000
[17:52:44] <IchGuckLive> if it is a M880a go for the numbers on the page
[17:52:47] <CHNCguy> its a HBS86
[17:53:07] <CHNCguy> hybrid servo drive with a stepper with live encoder feedback and PID loop within the drive
[17:53:27] <jthornton> don't see that one listed
[17:53:32] <CHNCguy> hi John, dont see HBS86 on that page
[17:53:37] <CHNCguy> its a new one
[17:53:53] <IchGuckLive> ok then go for the numbes in the datasheet
[17:54:01] <jthornton> they all appear to step on the rising edge
[17:54:11] <IchGuckLive> bu best to start with 2000 2000 6000 8000
[17:54:33] <IchGuckLive> CHNCguy: what is your leadscrew pitch
[17:55:03] <IchGuckLive> i guess your stepepr servo meets the 5divider not the 4
[17:55:03] <CHNCguy> leadscrew is .2 or 1tpi
[17:55:11] <CHNCguy> 5divider?

[17:57:22] <IchGuckLive> CHNCguy: so your scale is 1000
[17:57:24] <TangentAudio> i'm running a 7i43 ... not aware of an update, any pointers? i can't turn up much info in searching
[17:57:24] <CHNCguy> yes i think its a 6 to 1 gear ratio
[17:57:46] <IchGuckLive> oh then its 6000
[17:59:05] <IchGuckLive> TangentAudio: 5i25 7i43
[17:59:07] <CHNCguy> is that the scale?
[17:59:15] <IchGuckLive> CHNCguy: yes

[19:32:53] <CHNCguy> hey guys so im stuck, cant get my x axis to move hooked up step and dir (4 wires to my pulse and dir of my drive), can jog axis in AXIS but motor does not move, motor is powered and holding position
[19:33:37] <CHNCguy> IchGuck recommended upgrade to 2.5.2 I installed the 2.5.0 from the live cd download on the main linuxcnc site
[19:33:56] <skunkworks> More info.. How is it hooked up? what hardware and such
[19:34:17] <CHNCguy> 5i25 and 7i76
[19:34:22] <CHNCguy> got power to the card
[19:34:26] -!- AR_ has quit [Ping timeout: 264 seconds]
[19:34:40] <CHNCguy> x axis is 0 in the config panel so pins 2-5 are used on tb2
[19:35:12] <CHNCguy> measured voltage on pin 4 and i get 5v and pin 2 5v
[19:35:40] <CHNCguy> yet in the manual pin 3 and 5 are step and dir + (shouldnt they be 5v?)
[19:37:20] <CHNCguy> i have pin 2 to pulse - pin 3 to pulse +, pin 4 to dir - and pin 5 to dir +
[19:37:44] <CHNCguy> any ideas?
[19:39:44] -!- cwmma has quit [Quit: cwmma]
[19:40:28] <JT-Shop> IIRC step + and step - are a differential pair for single ended you use one and the correct 0 or 5v pin
[19:41:08] <JT-Shop> and 2.5.3 is the latest version
[19:42:09] <CHNCguy> not sure im following you JT, so do I use the 0 or 5 pins? 1 and 6?
[19:43:51] <CHNCguy> I confirmed that pul - and dir - are supposed to be 5v.
[19:44:24] <CHNCguy> My wiring is correct pinned it out (not hard with a 1 foot wire)
[19:44:54] <CHNCguy> My motor is holding position and correcting for error, so i know the drive in enabled
[19:45:26] -!- terabyte- [terabyte-!~terabyte@c-76-18-21-170.hsd1.fl.comcast.net] has joined #linuxcnc
[19:45:50] <CHNCguy> any ideas?
[19:48:58] <JT-Shop> if you need a positive step pulse you need to use pin 1 and pin 3 on the 7i76 IIRC
[19:49:23] <JT-Shop> I can dig my way into my plasma to be sure if pcw_home doesn't show up
[19:50:34] <CHNCguy> i checked the drive specs, it needs a 5v step0- and 5v DIR0- which I have
[19:51:32] <JT-Shop> what have you connected to step0 on your drive?
[19:52:07] <CHNCguy> step0- goes to pulse-
[19:53:03] <JT-Shop> pulse- is on the drive?
[19:53:15] <CHNCguy> yes sir
[19:53:34] <CHNCguy> i have pulse -/+ and dir+/-
[19:54:10] <JT-Shop> do you have a link to the manual for your drives?
[19:54:15] <CHNCguy> yes
[19:54:21] <CHNCguy> http://www.leadshine.com/UploadFile/Down/HBS86d.pdf
[19:54:29] <ju-emb> that are Optocoupler inputs
[19:54:50] <CHNCguy> .............
[19:54:59] <ju-emb> you need to connect + to the positive 5V (signal) and - to gnd
[19:55:29] <CHNCguy> on the drive or 7i76?
[19:55:54] <ju-emb> GND from 7i76 to - on drive
[19:56:08] <CHNCguy> gotcha one sec
[19:56:10] -!- GuShH_Lap has quit [Quit: ????]
[19:56:20] <ju-emb> signal from 7i76 to + on drive
[19:57:07] <JT-Shop> in the typical connections diagram it shows pul+ connected to VCC on the controller
[19:57:41] <JT-Shop> pul- connected to step- on the controller
[19:58:26] <JT-Shop> ju-emb, do you agree?
[19:58:48] <ju-emb> not yet, reading manual
[19:58:56] <JT-Shop> very last page
[19:59:08] <JT-Shop> it has opto inputs
[20:00:25] <ju-emb> yes, I think he should connect it as I say'd before
[20:00:27] <ju-emb> but let me check how are 7i76 output signals
[20:00:50] <ju-emb> the mesa cards normally have a 5V signal
[20:00:56] <ju-emb> on signals
[20:00:58] <CHNCguy> yes from pc
[20:01:03] <CHNCguy> i mean 5i25
[20:01:06] -!- uw has quit [Quit: Leaving]
[20:01:27] <ju-emb> doesn't matter are 5V or 3.3V
[20:01:38] <CHNCguy> im on 5v
[20:02:03] -!- Jymmmm has quit [Ping timeout: 260 seconds]
[20:02:07] <ju-emb> but it is not an open collector output like in the manual from drive that CHNCguy has
[20:03:49] <CHNCguy> mmmm
[20:03:56] <JT-Shop> the 7i76 has both - and + outputs for step and direction as well as 0v and 5v
[20:04:12] <ju-emb> since the drive has only a led with an 270 R resistor as input you cannot damage anything connecting
[20:04:15] <ju-emb> the signal from mesa card to Pul+ on drive and GND from Mesa to Pul- from drive
[20:04:33] -!- jfire has quit [Client Quit]
[20:05:51] <ju-emb> that's completely correct if you work with 5V levels on Mesa card

[20:06:30] <ju-emb> that's right sir
[20:06:34] <CHNCguy> in the manual it mentions pul (-) needs 4-5v

[20:07:10] <CHNCguy> is it the same for dir?
[20:07:19] <ju-emb> exactly
[20:07:30] <CHNCguy> dir+ to dir+ and pin1 to dir -?
[20:08:11] <ju-emb> don't know what pin 1 is, but GND of the MESA card should be connected to dir-
[20:08:31] <CHNCguy> pin 1 is gnd for first axis

[20:11:00] <ju-emb> but I see smoke here
[20:11:06] <CHNCguy> lol
[20:11:20] <CHNCguy> launching now lets see if she moves
[20:11:22] <ju-emb> ooops is coming from my cigaret
[20:11:37] <CHNCguy> nothing moving ;(
[20:12:01] <ju-emb> what's about enable from drive?
[20:12:53] <CHNCguy> ?
[20:13:14] <ju-emb> there is a pin called Enable on your Drive
[20:13:29] <CHNCguy> yes if left open it will be enabled
[20:13:35] <CHNCguy> the green light on the drive is on
[20:13:45] <JT-Shop> http://mesanet.com/pdf/parallel/7i76man.pdf
[20:14:12] <ju-emb> did you connect enable to 5V on mesa card?
[20:14:34] <ju-emb> thanks JT
[20:15:09] <CHNCguy> I have that JT in front of me printed out ;) Thanks tho ;D
[20:15:24] <CHNCguy> i did not connect the 5v enable to the mesa card
[20:15:58] <CHNCguy> if the drive is not enabled it will give me a red fault and i can move the drive by hand
[20:16:09] <ju-emb> normally you connect that Enable signal to your drive enable signal from hal
[20:16:13] <JT-Shop> the leadshine manual states the ena+ usually left unconnected (enabled)
[20:16:36] <JT-Shop> for testing he can leave it unconnected
[20:17:10] <ju-emb> but see exactly the same diagramm in drives manual
[20:17:23] <CHNCguy> i remember seeing something about rising and falling edge where was I supposed to set this?
[20:17:25] <ju-emb> that's an optocouppler too
[20:17:27] -!- Jymmm [Jymmm!~jymmm@unaffiliated/jymmm] has joined #linuxcnc
[20:17:28] <CHNCguy> does this matter?
[20:19:34] -!- terabyte- has quit [Quit: terabyte-]
[20:19:44] <ju-emb> manual say's a high on that pin enables the drive
[20:20:06] <andypugh> I think we can be pretty sure the drive is enabled.
[20:20:24] <JT-Shop> yep, if it is holding it's enabled
[20:20:43] <pcw_home> looks like the drive has differential inputs so you need to connect step+ to pul+ and step- to pul - etc
[20:21:09] -!- AR_ [AR_!~AR@] has joined #linuxcnc
[20:21:26] <ju-emb> that we figured out, and it's connected like that
[20:21:43] <JT-Shop> on page 7 it shows pul+ connected to VCC on the controller
[20:21:50] <ju-emb> but I'm not conform with let the enable open
[20:22:13] <ju-emb> JT forget about that
[20:22:48] <andypugh> JT-Shop: You would need to do that for 5V TTL drive from a parport. But the Mesa card has proper differential outputs so should be able to drive the optos directly (If I interpret what PCW is saying correctly)
[20:22:52] <ju-emb> that is if your controller works with open collector outputs, but Mesa card doesn't
[20:23:36] <andypugh> CHNCguy: Have you set the pulse length correctly?
[20:24:01] <ju-emb> Meass card has PushPull outputs
[20:24:08] -!- tinkerer has quit [Quit: Leaving.]
[20:24:12] <pcw_home> The 7i76 will work either way but differential is better
[20:24:22] <ju-emb> Mesa
[20:25:23] <andypugh> CHNCguy: In the HAL, what do you have connected to the hm2_5i25.stepgen.0.position-cmd pin?
[20:26:57] <ju-emb> OK I confirm that the Enable line can be left unconnected if the drive is configured to see that as enabled
[20:27:20] <pcw_home> bad idea...
[20:27:58] <ju-emb> ofcourse, but to see a first move it's ok
[20:28:02] <JT-Shop> pcw_home, he is just testing the motors on the bench
[20:28:11] <pcw_home> OK
[20:28:20] -!- morfic has quit [Ping timeout: 245 seconds]
[20:28:28] <JT-Shop> and yes I agree that after that enable should be working
[20:28:37] <pcw_home> as long as they can be set up in a reasonable way (Normally disabled)
[20:28:44] <JT-Shop> or disable
[20:29:11] <ju-emb> so let's see what else could be wrong
[20:30:01] <CHNCguy> just got back took a pee, haha one sec let me read through what i missed
[20:30:57] <pcw_home> "For reliable response, pulse width should be longer than 10μs. Series connect resistors
[20:30:58] <pcw_home> for current-limiting when +12V or +24V used. The same as DIR
[20:31:00] <pcw_home> and ENA signal:
[20:31:01] <pcw_home> so long 200 KHz...
[20:32:09] <CHNCguy> Andy let me check on sec
[20:34:08] <CHNCguy> andypugh: i dont see what u mean
[20:34:48] <CHNCguy> i see net x-pos-cmd axis.0.motor-pos-cmd +>hm2_5i25.stepgen.00.position-cmd
[20:34:55] <CHNCguy> => *
[20:35:52] <CHNCguy> I will also hook up the enable disable to linux somehow, but I am just bench testing
[20:35:54] <ju-emb> Drive manual say's < 200kHz
[20:36:02] <pcw_home> how do you have the drive step/dir wired?
[20:36:03] <pcw_home> should be:
[20:36:06] <pcw_home> STEP+ --> PUL+ STEP- --> PUL-
[20:36:07] <pcw_home> DIR+ --> DIR+ DIR- --> DIR -
[20:36:30] <CHNCguy> I had that wired with no success Ill wire it back that way 1 sec

[20:38:39] <JT-Shop> CHNCguy, what did you use for step and direction time?
[20:39:10] <pcw_home> the manual has conflicting specs
[20:39:14] <CHNCguy> i used 6k 6k and 2500 and 2500
[20:39:26] <CHNCguy> I just set them to 10k in the hal file ill try that now

[20:44:29] <CHNCguy> k so now how do I speed this baby up?
[20:44:35] <CHNCguy> Thanks a ton guys! :D
[20:46:03] <JT-Shop> what did you set velocity and acceleration to?
[20:46:44] <CHNCguy> default
[20:46:59] <CHNCguy> how do i get back into the file to adjust some params?
[20:47:35] <pcw_home> is likely your scale factor is wrong (how many line encoder do you have?)
[20:47:54] <CHNCguy> 1000ppr I set the drive to 1000 pulse per rev also
[20:49:12] <JT-Shop> CHNCguy, your using a pncconf generated configuration?
[20:49:44] <pcw_home> a 1000 PPR encoder has 4000 counts/rev
[20:49:49] <CHNCguy> yes
[20:50:12] <JT-Shop> run it again and modify your file
[20:50:36] <pcw_home> so pulses/rev will be 4000
[20:51:22] <CHNCguy> so what do u want me to modify in the file?
[20:52:47] <CHNCguy> i see it now
[20:52:56] <CHNCguy> the max velocity in each axis right?
[20:53:53] <jthornton> yes and acceleration
[20:54:20] <jthornton> how fast can the axes go?
[20:55:20] <CHNCguy> supposed to be 200ipm with the old weak servos 1.8nm, id like to get 400+ with these 8nm ones.
[20:56:11] <pcw_home> You may find the the step motors will not go as fast as the servos
[20:56:36] <CHNCguy> these are hybrids, they can go 3k
[20:56:47] <pcw_home> with what torque?
[20:57:04] <CHNCguy> 8nm low rpm, and at 3k 1.8nm
[20:57:17] <jthornton> nice pnconf mixes units for velocity and acceleration
[20:57:20] <CHNCguy> stock dc servos were 1.8nm max
[20:57:40] <pcw_home> 1.8NM peak?
[20:58:15] <CHNCguy> yes, that was their specs, they were also geared 6 to 1
[20:58:49] <CHNCguy> jbthorton, u got a chnc too right? They were 1.8nm on urs too right?
[20:59:07] <jthornton> CHNCguy, usually I find that acceleration is 10-20 times velocity
[20:59:14] <jthornton> yes I have a CHNC 1
[20:59:31] <jthornton> so try 200 for velocity and 50 for acceleration
[20:59:51] <CHNCguy> ok 1 sec
[20:59:55] <jthornton> and notice that the units are not the same between velocity and acceleration
[21:00:11] <pcw_home> note that stepmotor torque ~ servo peak torque
[21:00:24] <pcw_home> (the most it can deliver)
[21:00:55] <jthornton> stepmotors are strongest when holding still IIRC
[21:01:08] <jthornton> on a full step I assume
[21:01:13] <CHNCguy> these are hybrid steppers, they act more like a ac servo then a stepper.
[21:01:46] <pcw_home> Yes true of servos as well but servomotors tend to have a much slower torque falloff
[21:02:18] <pcw_home> Well except the torque curve is the same as a step motor
[21:02:45] <CHNCguy> thats why I chose these hybrids and see how they work out, supposedly they are the best of both worlds
[21:03:01] <CHNCguy> if they suck ill just exchange them for ac servos no biggy
[21:03:14] <pcw_home> The are much better in that they can not stall in the normal step motor sense
[21:04:29] <pcw_home> they still have step motor torques loss at speed (and are not available/practical in large sizes)

[23:01:37] <CHNCguy> ok guys I got my motor going good, now how do I add an estop so the system? With the estop ladder in the config file
[23:01:38] <CHNCguy> ?
[23:02:34] <andypugh> Ideally e-stop should be hardware all the way.
[23:03:19] <andypugh> You can let software be one cause of e-stop, and it is good to tell LinuxCNC that the e-stop has been hit.
[23:03:50] <Tom_itx> net estop-loop hm2_[HOSTMOT2](BOARD).0.gpio.015.in_not => iocontrol.0.emc-enable-in
[23:04:08] <Tom_itx> minimal
[23:04:13] <CHNCguy> not sure what to do with that tom_itx ;)
[23:04:27] <CHNCguy> is that io15?
[23:04:29] <Tom_itx> sub the hostmot2 io for yours
[23:04:35] <andypugh> Too minimal for a machine with that speed and power..
[23:06:06] <CHNCguy> I was thinking, estop tied to relay which would kill a bank of things, like spindle input voltage (push it to 0 and stop spindle), hardware disable to drives, and a signal to linuxcnc saying an estop is triggered
[23:06:17] <Tom_itx> good idea
[23:06:18] <Tom_itx> yes

[23:07:57] <CHNCguy> so i got my motors running, now the next thing I would like to work on is an estop, in the config there is a ladder for this, how do I get this to work?
[23:07:58] <CHNCguy> ;D

[23:17:12] <CHNCguy> how would I hook up an MPG to my 7i76?
[23:17:27] <Tom_itx> encoder inputs
[23:18:30] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/
[23:18:36] <Tom_itx> there's my configs
[23:18:47] <Tom_itx> look in my_jog.hal for mpg
[23:19:04] <CHNCguy> not loading :(
[23:19:23] <Tom_itx> port 81 blocked?
[23:19:35] <CHNCguy> just says cant connect
[23:19:40] <CHNCguy> to ur link
[23:20:10] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/my_jog.hal
[23:20:26] <Tom_itx> if that doesn't work hang on
[23:21:15] <CHNCguy> dont work
[23:21:28] <Tom_itx> is your port81 blocked?
[23:23:35] <CHNCguy> brb
[23:23:47] <kengu> is there a linuxcnc error log file somewhere on the filesystem?

[23:35:13] <heathmanc> Got a firmware problem with a 5i20 and 7i48
[23:35:26] <heathmanc> Have firmw are
[23:35:55] <heathmanc> .8 downloaded and installed, yet does shows it loading .7
[23:36:27] <TangentAudio> where did you get the firmware versions by the way? i'm having some 7i43 firmware issues myself
[23:36:57] <kengu> pretty hard to find this kind of keypads, not maybe in pendant but bare, http://www.cnccookbook.com/img/LatheStuff/CNCConversion/CNCPanels/USBKbdPendant.jpg to hack with
[23:37:12] <heathmanc> dmesg that is. Also gives a muxed encoder v2 issue and says to update firmware
[23:37:56] <heathmanc> downloaded with synaptic package manager
[23:40:22] <andypugh> heathmanc: Better to get the firmware fresh from Mesa

[23:45:00] <kengu> andypugh: uumm. matrix is the key, thanks. i was missing that earlier but still they do not offer one with the right prints to start with..

[23:47:53] <andypugh> No. I think that there are straightforward ways to make custom prints.
[23:48:38] <jthornton> CHNCguy, you still around?
[23:48:48] <CHNCguy> yupo
[23:49:07] <CHNCguy> whats up ;)?
[23:49:20] <kengu> yeah. i think i will quit on trying and then just settle with one of those
[23:49:33] <jthornton> you make any progress?
[23:49:43] <CHNCguy> yup
[23:49:50] <CHNCguy> i got the motors to work just fine
[23:49:56] <CHNCguy> problem was the step timing
[23:50:00] <jthornton> cool, you figure out where to hook the MPG up to?
[23:50:07] <CHNCguy> >=2000 for each wont work
[23:50:10] <CHNCguy> i mean
[23:50:10] <jthornton> it's always the details

[23:50:24] -!- seb_kuzminsky has quit [Ping timeout: 246 seconds]
[23:50:25] <CHNCguy> less than or equal to 2000 wont work
[23:50:30] <CHNCguy> same thing for 10k and above
[23:50:45] <CHNCguy> 2800 seemed to work great, the faster the pulse, the faster the motor
[23:51:01] -!- hm2-buildmaster has quit [Ping timeout: 248 seconds]
[23:51:02] <CHNCguy> I did not yet figure out the mpg, any light you want to shed? :)
[23:51:03] <jthornton> when you settle in on a number add it to the wiki page
[23:51:09] <CHNCguy> ok
[23:51:15] -!- linuxcnc-build has quit [Ping timeout: 245 seconds]
[23:51:42] <jthornton> yes, there are 4 pins you can use for the MPG and you need mode 3 IIRC to use those pins as MPG
[23:52:26] <andypugh> CHNCguy: You have an encoder counter on the 7i76, though probably want to keep that for the spindle.
[23:52:42] <CHNCguy> mode 3?
[23:52:49] <CHNCguy> yes I set that one to spindle encoder in
[23:53:00] -!- adb has quit [Ping timeout: 252 seconds]
[23:53:18] <andypugh> CHNCguy: I would look at the 7i73 pendant interface, it will connect to the smart-serial port on the 7i76 and can easily interface the entire control panel.
[23:53:30] <CHNCguy> is the io connector 3 right side num 0 where is says multihand wheel was one of the drop downs?
[23:53:38] <andypugh> kengu http://www.rapidkeypads.com
[23:53:53] <CHNCguy> i purchased the 7i73 as recommended a while ago
[23:53:57] <jthornton> sserial_port_0=300xxx
[23:54:01] <andypugh> Dunno, I have never used Pncconf :-)
[23:54:22] <jthornton> me neither
[23:54:31] <andypugh> In that case, wire the mpg to the 7i74 mpg terminals :-)
[23:54:42] <andypugh> (7i73, I mean)
[23:57:12] * jthornton just looked at the 7i73 and that is pretty neat
[23:57:13] <CHNCguy> sounds good to me ;) Ill try to work on that with you guys tomorrow, don't have it right now. Also what voltage do I need to power it, 12v? 24v?
[23:57:20] <andypugh> CHNCguy: For wiring individual wires to the Mesa headers, I find these really useful: http://uk.mouser.com/ProductDetail/Harwin/M20-1071200/?qs=sGAEpiMZZMs%252bGHln7q6pmzlZUuX%2f53qjGdAcq81cToY%3d
[23:57:44] <andypugh> CHNCguy: Just google 7i73man :-)
[23:57:59] <CHNCguy> not the 7i73v, the nominal voltage for mpgs
[23:58:06] <jthornton> http://www.mesanet.com/pdf/parallel/7i73man.pdf
[23:58:11] <jthornton> 5v usually
[23:58:13] <andypugh> That is the 12+12, but they come in a variety of sizes down to 2+2
[23:58:16] <CHNCguy> or what was the voltage for your john?
[23:58:47] <jthornton> MPG's are usually 5v
[23:59:25] <jthornton> andypugh, so those have the same pin spacing as the 7i73 headers?
