It should reduce the number of passed variables for each of the subroutines. Yes, you could. For this purpose I'd use the G54 fixture offset (settable with the axis touch off button or MDI G10 L2 P1 ...) to set the corner of the usable area as X0 Y0, and then set a G92 coordinate system offset before making each part. (I'm sure there are other ways you could do this, for instance by using the G54 fixture offset for the global system and the G55 fixture offset for the this part system) I modified the original program to do this. Now the O100 sub can assume that X0Y0 is the lower left corner of this part, and is simplified accordingly. You could further simplify by coding the depth, retract, and feeds directly in the O100 sub instead of passing them through all the levels of subroutine.

Re: [Emc-users] EMC 2.2.7 + 7i43 + Ted's sample, and same error than using EMC 2.2.6 + 7i43 + Ted's sample.... What now?
How did the DOS testing turn out? OK... sorry for the delay, but my work is killing me. Finaly i managed (lack of time not brain) to burn a DOS start cd and put there the files to make the test. When sc7i43p svst4_4b.bit 378, everything went fine. Did sc7i43P report that the 7I43 had a 400K FPGA? When epptest 378 It says something like this: error count 1: loop count :10 error count 2: loop count :20 error count 3: loop count :30 And so on. Well it should say something like: Pass: 1 Error Count: 0 loop count: 10 Pass: 2 Error Count: 0 loop count: 20 Pass: 3 Error Count: 0 loop count: 30 ... A) It this an error on every 10 loops or there is no error at all?. No errors. Each loop does 24 EPP operations (2 32 bit writes and 2 32 bit reads, so it did 7.2 million EPP operations without error B) When i did epptest for the first time WITHOUT sc7i43 svst4_4b.it first, it said something like Error: send ah21 read or so, so i think that A means no error. If there are errors you will get the sent , read messages So, if this means there is nothing wrong with my computer or the card i guess the failure comes from the driver... ??or it means i have to check something? If you can verify that the sc7I43p program reported that the FPGA was 400K it mean that your hardware is fine. At this point its most likely a HAL or startup issue of some kind. It could be a driver issue but that not too likely as others have gotten firmware loading to work without problems Can you post your HAL file to imagebin.ca (again?) so one of the (few) 7I43 HAL gurus can help?

My 40 or so feet that has been swinging in the breeze from the house to my shop, has probably stretched, or slipped in the cable ties that bind it, about a foot in 5 years, I had to undo the hanger at the house and pull it back tight about a year ago, couldn't carry ladders and things in the yard without hitting it plus it had sagged into the top of the 4' wide swinging doors of the shop. But as near as I can tell, its as good as ever, it matched my dsl bandwidth when I ssh-logged into it just now, issued a sudo reboot, then pinged it till it came back, did an apt-get update, apt-get install emc2, which put the 2.2.8 version on it. A length of real metal electric fence wire, (not plastic unless its real kevlar) with the cat-5 hanging from it via those plastic s-hooks you hang christmas lights on the gutters with should work until the s-hooks go away from the sunlight. I would not tape it directly to the messenger wire if its metalic due to the close proximity of the metal in the messenger wire effecting its impedance. The s-hooks will give about a 3/4 spacing which should be fine. I used that bright blue cat-5 stuff Belden makes, it is apparently surviving the sunshine quite well so far.

Re: [Emc-users] Changes to hostmot2 in 2.2.8
Sebastian, Yep, that got it. Regards, Eric That did it. Embarrasingly, it's the same kind of bug as bit me just recently... You told it to use zero encoders, and it still tried to poke at it. If you can stand turning on one encoder instance (num_encoders=1) it'll work. If not, try Trunk, i'm commiting a fix in the next five minutes. -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada. The future of the web can't happen without you.

Three things: You can recover an unapplied G92 offset with G92.3 You can keep the G92 from getting unapplied by using % instead of M2/M30 You can use G54 offset just as easily, or more easily, than G92 by using Touch off in AXIS.

This machine is plugged into that 8 port switch, as is the cable to the shop, and several other cables here in the house so I can hook up a box I'm working on in case I am. With dd-wrt in the path to the internet, I don't run a firewall on any of the local boxes, dd-wrt stops all that crap. That old x86 box has been stripped, no drives at all, but has a compact flash adapter ($4) on the end of the primary IDE cable, and it boots dd-wrt from the cf card. dd-wrt is the best kept secret in the firewall business.

OK... sorry for the delay, but my work is killing me. Finaly i managed (lack of time not brain) to burn a DOS start cd and put there the files to make the test. When sc7i43p svst4_4b.bit 378, everything went fine. Did sc7i43P report that the 7I43 had a 400K FPGA? When epptest 378 It says something like this: error count 1: loop count :10 error count 2: loop count :20 error count 3: loop count :30 And so on. Well it should say something like: Pass: 1 Error Count: 0 loop count: 10 Pass: 2 Error Count: 0 loop count: 20 Pass: 3 Error Count: 0 loop count: 30 ... A) It this an error on every 10 loops or there is no error at all?. No errors. Each loop does 24 EPP operations (2 32 bit writes and 2 32 bit reads, so it did 7.2 million EPP operations without error B) When i did epptest for the first time WITHOUT sc7i43 svst4_4b.it first, it said something like Error: send ah21 read or so, so i think that A means no error. If there are errors you will get the sent , read messages So, if this means there is nothing wrong with my computer or the card i guess the failure comes from the driver... ??or it means i have to check something? If you can verify that the sc7I43p program reported that the FPGA was 400K it mean that your hardware is fine. At this point its most likely a HAL or startup issue of some kind. It could be a driver issue but that not too likely as others have gotten firmware loading to work without problems Can you post your HAL file to imagebin.ca (again?) so one of the (few) 7I43 HAL gurus can help?

[Emc-users] A Classicladder Problem in TRUNK
I have a lathe that has an automated tool turret, which I had working with a version of TRUNK several months ago. I cvs updated my copy of TRUNK and recompiled yesterday and I now have a problem in Classicladder. I have one S32 input to Classicladder which is connected to the tool prep number from iocontrol. The tool prep number changes when a Tn block is executed (in MDI), and shows up correctly in the HAL configuration display in Axis, both on iocontrol.0.tool-prep-number, and on classicladder.0.s32in-00. The problem is that the value of %W0 in Classicladder stays equal to 0, not the value of classicladder.0.s32in-00.

Far better in fact than I expected it to. When I put it up, I figured on maybe a years service max. Thanks Gene, I am responding to you appropriately enough from my barn. Cool! The very machine controller itself is my window to the EMC2 community. Now I can pastebin my errors for all the world to see. Verrry nice. I had no trouble at all installing the ver 2.2.8 update. Now back to fixing the spindle speed display- regards, Tom Chuckle, good to hear, Tom. As for the spindle speed display, I can't help. I can control mine, with a PMDX-106, but have no tach feedback. It would be nice though, since the S commands have a 0-9 (or 10, I forget the upper bound), we had some sort of a display widget progress bar that displayed that setting, and changed color from red for the M stop, to green for the M run. Or is there if one sets up the right hal stuff? I haven't a clue. I have in the axis display at present 3 buttons, a plus for fwd, a - for reverse, and a stop in the middle, speed according to how many times I click the + or - direction button. But no speed indication other than how much noise the spindle is making. Which with that sloppily meshed gear drive on the micromill, can be considerable. At some point, I intend to address both the noise and its limited rpm range. For some things, 2500 rpm is about 1/4 what I need. NDI what 10 grand would do to those spindle bearings though. They seem to be ok yet, and probably have 500 hours at 2 grand plus on them now. Which surprises me since I have to use a hammer on the top of the drawbar bolt to change cutter tools. I use a wooden mallet for that generally. Speed display widget in axis? Any thoughts, suggestions? Thanks. -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

Re: [Emc-users] Following Error Problem Using 5i20 and Stepper Motors
A bunch of us, including Matt, John K, Peter and Seb worked further on troubleshooting this on irc earlier. This bug specifically affects hostmot2 systems where the step rate is above 60% or so of the maximum step rate given the user specified step length and space. Peter has now identified a bug in the FPGA firmware, and plans to have a fix soon. When this happens, we'll be able to provide instructions and a download link to get an updated firmware if you've been affected by the issue. (and in 2.2.9, but I simply don't see that happening until January) There's a workaround. In Peter's words from the irc chat: For the time being a workaround is to set StepSpace to 0 and limit maximum velocity in software (to 90% or so of hardware limit) If you're interested in boring technical details, and also some discussion about developers' pets and other miscellaneous noise, you can take a look at the whole irc log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emcdevel/2008-12-16.txt starting at 21:13 GMT http://www.linuxcnc.org/irc/irc.freenode.net:6667/emcdevel/2008-12-17.txt ending around 03:25 GMT Jeff -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

Re: [Emc-users] end of program
Thanks, but no. I still want to just end the program where it sets the stop button so to speak, without jacking with my offsets, and restoring manual control. And without me having to save my offsets, and then restore them at the beginning of the file. With the method that Ray described with G92.2 and G92.3, its still several un-necessary steps I think. I mean, what if it is the first time you run the program? Would you have to set the offsets with G92 in MDI and then save with G92.2 in MDI, then place G92.3 at the beginning of every file? It'd be less tedious if I could just end the program, leave my offsets as they were, jog the head out of the way (without having to hit the stop button first), swap the stock, then hit start again. I could write the routine into the postprocessor to do what I need (maybe), but I use the same CAM software for different purposes where the retract vector is different depending on which machine and which operation. Let me also point out I have been a long time user of EMC (love it!), but I just recently started using home switches and I am searching for their usefulness. Previously without home switches, I just zeroed off of a part, and never had to jack with offsets. At this point, they make no sense and are cumbersome to have. I am hoping that there's just some connection I am not making and it will all of a sudden make sense once I get that clue that connects the dots.

Re: [Emc-users] end of program
Len, Take the time to learn G54,G55 etc offsets. Once you learn them you will NEVER want to use anything else. try this assuming your home position the center of your table in XY and the Z up position put this next line on the first line of your program G10 L2 P2 X-1.0 Y-1.0 Z-1.0 put G55 on the second line - it doesn't have to be on the second line - you can put it on the first motion line the G10 line doesn't have to be in the first line - it writes the XYZ values into the parameters for G55 your zero will be the coordinates X-1.0 Y-1.0 Z-1.0 (from home position) home your machine and start your program play with the numbers to see what effect they have on the zero position L3 is G56 L4 is G57 On Tue, Dec 16, 2008 at 10:44 PM, Len Shelton l...@probotix.com wrote: Thanks, but no.

Re: [Emc-users] Am I overloading the servo loop with my s pindle encoder?
Gene Heskett gene.hesk...@... writes: ... Speed display widget in axis? Any thoughts, suggestions? Thanks. Gene, I am using a pyVCP panel in Axis that has a spindle rpm bar, lifted from Anders Wallins generously provided ini and hal files on his web page here: http://www.anderswallin.net/category/cnc/emc/ Thus far, I can display 0 to 4000 rpm in a nice steady green bar, but as the spindle speed increases above that point (my spindle goes up to 6000 rpm), the bar (and the floating point value of the rev-scaled hal pin that it is linked to) starts to bounce between extreme negative and positive integers. My diagnosis was that the frequency of the incoming pulse stream (m5i20.0.enc-03-position) was too great (120kHz) to be scaled accurately in a slow thread. Here is the hal file configuration as provided by Anders: # load ddt for rpm calc loadrt ddt count=1 loadrt scale count=2 addf ddt.0 slow-thread addf scale.0 slow-thread addf scale.1 servo-thread # 500-line encoder gives 2000 pulses per rev setp m5i20.0.enc-03-scale -2000 # RPM = revolutions per minute net ddt-scale scale.0.gain sets ddt-scale 60 net spindle-pos m5i20.0.enc-03-position net spindle-pos ddt.0.in # spindle position to motion-control for threading net spindle-pos motion.spindle-revs net spindle-index-en motion.spindle-index-enable m5i20.0.enc-03-index-enable net rev-count ddt.0.out net rev-count scale.0.in net rev-scaled scale.0.out # 2000 Hz corresponds to 5400 RPM # so scale Hz values by 1/2.7 net rpm-scale scale.1.gain sets rpm-scale 0.37037037 Stephen and Sebastian suggested using a new pin in Hostmot2 (ver.2.2.8) called encoder.03.velocity instead of the m5i20.0.enc-03-position pin used in the example above. That should alleviate having to sample/scale it in a slow thread. I will try that tomorrow. Tom -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.
