[Emc-users] Z axix direction problem
Hi I have problem with interpretation of G code. Basic problem is with Z axis. I set G55 right on the face of part. Start with G54, than G55 X0 Y0 Z0 When machine reads Z 0.1 (positive) volume machine moves from G55 plane away from home. When machine reads Z -0.3(negative) volume machine moves from G55 plane to the direction of home. My program created with CAM based that positive volume will move machine closer to home and negative volume moves machine away from home position. Did I explain problem? If so where is the solution?

I kept the original brush servos and converted them to optical (encoders 2000 ppr). I have been generating complex toolpaths in CAM and I saw the speeds slow a bit when I hit lots of little line segments, but I was still getting max 30 ipm. So I started to use the G64 command (example: G64 P0.0015) and I immediately got a huge jump in attainable cutting speeds; as much as 100 ipm, which is a lot more than I need. I have not yet experimented with adjusting the segment tolerance settings in CAM yet, but I can turn on arcs in my CAM package which helps with the cutting speed, but the output ngc file seems to have a mix arcs and line segments in a way that I cannot control (as far I know...). Still, I have more speed than I can use, and very good accuracy. After reading and evaluating Mach3 vs. Emc2 for a year, I decided to go with Emc2 mainly because with encoders, Emc2 always knows where the joints are and displays there positions, even when you turn off or estop the servo amps. This allows you to pause or estop the machine if I don't like what its doing, and then correct the issue (even re-load the edited toolpath) - and resume where I left off without losing position or accuracy. I am very happy with it.

I've looked hard for the original message, but can't find it. But, I seem to recall that I got over 600 vectors per second when I had the right G61.1 setting, so that the allowance for divergence between the lines was sufficient to maintain the commanded feedrate. This was on a 600 MHz Pentium 3 with a "real" servo control, so there were no software step generation issues. The test program was a 2" diameter circle composed of 10,000 vectors.

Flo, If you are using CAM to generate your G-code maximize the path tolerance to reduce the number of line segments. I do 3D contouring in VisualMill and can double the size of my G-code by specifying .001 tolerance. Unless you are machining with a very rigid state of the art machine you wil never see the difference. I run with a segment tolerance of .005. Also check to make sure that you are outputting circles intead of line segments.

Re: [Emc-users] Replacing Mach 3 by EMC? Performace?
Hi Flo, I try not to say bad things about Mach, as one isn't supposed to say about any competitors. I'll try to say good things about emc2 though ;) I think (after trying some plasma cutting on Mach today for the first time) that emc2 should definately work better than that on a file with short segments. I don't exclude this machine to be horribly out of tune, but I saw cutting speeds of 3000 mm/min going down to maybe 3-400 mm/min on segments about 2-3mm long. I would assume it should do better than that. Anyways, get a LiveCD, try it yourself - if you don't have any complex things set up, then you can see what happens. Maybe even limit the config to just get your motors tuned up and try a dry run. Be sure to use G64 Pxx to set max deviation (I use something like G64 P0.1 for mm). This allows some corner cutting, to keep velocity high enough, with the loss of some precision. The more loss, the faster it goes. To find the right balance is up to you.

You need to read read and read again. :) http://linuxcnc.org/docview/html/ You will want to do a latency test on the hardware (to make your hardware will decent realtime performance) http://www.linuxcnc.org/docview/html//config_stepconf.html#sec:Latency-Test That being said... You can test emc for performance by downloading the livecd here http://www.linuxcnc.org/content/view/21/4/lang,en/ and booting from it. It will not change anyting on your existing computer but will allow you to test emc2. There are a bunch of sim configs that will allow you to test gcode to see how it runs. (you might want to make a config though with your known max velocities and accelerations.) As far as how smooth it will run. Emc has a naive cam detector when using G64Px.xxx. This combines line segments that are within the Px.xxx tolerance. It really helps improve the speed of cutting. http://www.linuxcnc.org/docview/html//gcode_main.html#sub:G61,-G61.1,-G64: and http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TrajectoryControl Give it a try. sam fr...@fs.tum.de wrote: > Hallo, > I new to EMC and before I start to work my self through the documentation > and try to get it running with my machine I’d like here your opinions: > > I’m looking for a solution to control a 4 axis CNC mill (3 axis router + > rotator axis).

Re: [Emc-users] Rattling steppers losing steps
It's worse than that -- in 2.2.x, stepconf will always use a mode called "doublestep", in which step pulse width is limited to 1/4 of the BASE_PERIOD by the hardware driver even though the GUI will appear to accept larger values. This is an unfortunate limitation, but the changes to stepconf to fix it are too invasive to be put in 2.2.x. For machines which require the step pulse width to be fairly wide, you're stuck hand-editing inifiles for the time being. By starting with the sample-configs "stepper" directory, you can add the appropriate "setp stepgen.#.steplen" settings to your pinout.hal file.

[Emc-users] Rattling steppers losing steps
Gentlemen, now that I've got so far that my little PCB drilling machine is all set up with EMC2, she seemingly feels very uneasy. Compared to my former setup, driver board and everything being unchanged, the steppers rattle and lose steps and show all signs of maladjustment. The problem could be that I can't reduce pulse speed to less than 10 kHz (5 ns max. in stepconfig, basic information page, step time and step space settings each). My driver board accepts only 5 kHz at max. There must be a file somewhere containing the information that reduces the nanosecond entry to 5 when I try to set it higher. Where can I change the max. settings of stepconfig, so I will be able to test slow puls rates?
