Re: [Emc-users] Could my GeForce4 Ti 4600 simply be too underpowered?
That makes sense. It could be why the 8800GTX in my new machine is just a very nice card, and not 'killer.' I have Portal running through Steam, and even though I've finally managed to get it all working great, it's chuggy. It should fly on this card. Thanks for the info.

The NML libraries are relatively independent from the rest of EMC2. You
could just make a header/class interface/whatever the C# equivalent is
for the NML library - more or less a c# implementation of
emc/nml_intf/emc.{cc,hh}. Where you may get into trouble is with the
emc.hh file - that's where the specific NML messages are defined, and
that's GPL - not LGPL. Anything based on it would have to be GPL as
well (hopefully not a problem :) ).
I suspect that the easier methods are based on using one or more of the
existing programs that already have NML implementations: emcsh or
emcrsh. And maybe HALUI or similar. Then there's the python library,
which can be pretty easily used for various functions (see jdi.py for a
simple example).
You may also want to think about going straight to HAL, if you want to
bypass the interpreter anyway. (the trajectory planner is still quite
useful though)

Re: [Emc-users] Problem after installation of EMC2 on Ubuntu 8.04
Seem you booted the wrong kernel. If you install emc2 after you installed a regular Ubuntu then you'll get both the RTAI kernel and the generic Ubuntu kernel installed. If there are updates to the generic Ubuntu kernel, then that one will be automatically selected on your next boot. You can change the order (so that the rtai kernel starts first) either by changing /boot/grub/menu.lst or by hitting Esc when the PC starts booting (right after BIOS POST), then you can select which kernel to boot.

Re: [Emc-users] How does axis communicate with emc?
Alan, In addition to what Stephen said, see if emcrsh does what you want. Take any one of the sim configurations (tkemc is a good one) and add: loadusr emcrsh to one of the hal files (servo_sim.hal for example) Run EMC, then open a terminal session and enter: telnet localhost 5007 After it connects, type help. To establish a session with EMC, enter: Hello EMC client 1.0 To get rid of the command echo, enter: Set echo off To command the machine, enable the session with: Set enable EMCTOO Alternatively, you can run from another computer over the network by entering: telnet DNS or IP address 5007 Your program just needs to send and process the same commands as you type into the telnet session. So long as you write your application from the interface specification, i.e. specifically by not borrowing any of the code from the server side, there should not be any GPL implications. Well on this specific interface anyway. You can also find the interface definition here in the source code: http://cvs.linuxcnc.org/cvs/emc2/src/emc/usr_intf/emcrsh.cc?rev=1.10;content -type=text%2Fplain Scroll down one page. I need to put this into a wiki page. BTW, I just checked in an update enhancing options that can be specified on the command line. To use these, you will need to build from source until the next release. HTH, Eric I want to connect directly to emc from some software I am developing.

Re: [Emc-users] G33 spindle count
John, Changed the scale to 50. 1 turn of the spindle increases the spindle-pos by 1 now. I thought the phase-Z was responsable for counting the spindle revs. Running eg G33 Z10 K.1 (assuming .1 mm per turn) moves very shocky. Also, running G33 Z10 K.2 seems to go up at full speed. Another strange behaviour: running the same command moves in the same shocky velocity till Z7, then stands there waiting for some time before continuing... Is there something else I would need in the config?

[Emc-users] Probing (was Re: Homing)
I didn't make it through the video, but emc supports probing with G38.2. G38.2 probe does a straight movement and records the feedback position at the time a digital input goes TRUE. It then decelerates the axis within machine constraints. The resulting values are stored in interpreter parameters and can be used e.g., with G10 L2 or G92 to modify the coordinate system in effect. The very old gcode reference http://www.isd.mel.nist.gov/personnel/kramer/pubs/RS274NGC_3.web/RS274NGC_33a.html#1013622 includes gcode to find the center of a circle. I don't think this example has made it forward into the current emc documentation, but I think it's fairly likely to still work.

Geert De Pecker wrote: Just changed to the code below, but G33 keeps doing very strange. Also, the motion.spindle-speed-in displays 4.3 instead of the approx 200 rpm the spindle is doing. Would I need to put a scale component in to change from the rotations per second (encoder reading per second?) to rotations per minute? Maybe this is what is causing the strange moves. setp encoder.0.counter-mode true setp encoder.0.x4-mode false Does your encoder have quadrature (two 50 ppr channels)? This mode only uses one, and gives you 50 counts per rev, using quadrature can give you 200 counts per rev, which should be smoother. setp encoder.0.position-scale 50 net spindle-phase-A = parport.0.pin-11-in = encoder.0.phase-A net spindle-phase-Z = parport.0.pin-10-in = encoder.0.phase-Z #net spindle-phase-A = parport.0.pin-11-in = encoder.0.phase-A encoder.0.phase-Z net spindle-index-enable motion.spindle-index-enable = encoder.0.index-enable net spindle-pos encoder.0.position = motion.spindle-revs This signal is in revolutions, and is used for G33 (threading) as well as for the G76 threading canned cycle, and rigid tapping. net spindle-velocity = encoder.0.velocity = motion.spindle-speed-in This signal is in revs per second, and is used for G95 (feed per revolution). It is NOT used for threading. Regarding the runs full speed at higher pitches - you need to do the math to make sure you aren't asking the impossible. For example, if your spindle speed is 1000 RPM, and you command a pitch if 0.2mm, the Z axis will have to move at 1000 X 0.2 = 200mm/minute to cut that thread. If your Z axis can't do that, it will go as fast as it can, and changing the pitch to a higher value like 0.3 won't make it go any faster. What are the velocity and accel limits for your Z axis? What spindle speed are you using for the test?

[Emc-users] Unusual Threading Behavior
I am running EMC 2.1.0 if the first code I open after loading EMC is a threading code it will operate as I expect. I can run the code 20+ times and it works perfectly, if I open a different threading code it too will work as it should. As soon as I open any code that does not thread run that code and then return to a threading code it will run at my G0 velocity and not the appropriate feed rate. This is really an annoying problem, as I thought I was messing something up, I would test the code start running the part and get bad threads took awhile to realize the code is fine as long as it is the first code. Ideas?

I don't understand what you are saying. What is open a code. Does code mean a g-code like G33? Or are you using code to mean an entire g-code program.

By code I am referring to an entire g-code file some G0's some G76 etc... What modal value would effect G76's ability to properly calculate the feed rate? I should mention that even when it threads at the G0 speed it does sync with the encoder index pulse. --- On Sun, 10/5/08, John Kasunich [EMAIL PROTECTED] wrote: From: John Kasunich [EMAIL PROTECTED] Subject: Re: [Emc-users] Unusual Threading Behavior To: [EMAIL PROTECTED], Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Date: Sunday, October 5, 2008, 7:04 PM richard harris wrote: I am running EMC 2.1.0 if the first code I open after loading EMC is a threading code it will operate as I expect.

I should mention that even when it threads at the G0 speed it does sync with the encoder index pulse. Off the top of my head I can't think of anything, but that is the first thing I'd try to rule out. As a test, write down the active codes (displayed in a box in Axis), then run the first program, and write them down again - look for differences. Actually, I did thing of one that would make a huge difference - G20/G21. If the pitch is supposed to be in mm, and it gets changed to inches, then the axis will need to move 25x faster and will probably be at the velocity limit. That's probably not it, but check for any other possibilities. If you can't find anything, you are going to have to make it possible for one or more EMC developers to reproduce the problem. That means we need to be able to run your exact configuration and the exact g-code programs that make the problem happen.

Re: [Emc-users] Probing (was Re: Homing)
Gentlemen, A comment on the probing cycle at the URL in Jeff's post. If the center of the probe is not EXACTLY aligned with the centerline of the spindle the coordinates obtained will not be accurate to the center of the spindle. A probe calibration routine to determine and save the inaccuracy on X and Y will need to be done before any probing. This would need to be incorporated into the probe cycle at the URL. thanks Stuart - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
