[Emc-users] Parametric g-code with pyvcp

2009-10-05 Thread 5150
Hi, is it possible to write a g-code program setting, for example, a linear motion distance with a halui parameter? My goal is to use a pyvcp scale to set the position I want to move to: G0 X[pyvcp.dimension] Thank you Luigi

Dear Steve Try removing the O sub/endsub lines and loading the files individually. That should get you a line number where the error occurs (I hope). The files were actually converted into subfiles from standalone files. The standalone files work without any error and do not show O

1 The medical grade RFI filters have a much smaller capacitance between line and ground, and usually have more series inductance. It can be tough to find medical style line filters with high current ratings. Plus, they're expensive... 2. I recently spoke with an engineer from North Shore Safety

To generate lots of debug messages: In your.ini file section [RS274NGC] add the line LOG_LEVEL = 999 Then the file emc_log will get a log containing the interpreter activity regarding o-words, subroutines, etc. You probably don't want this enabled when you are doing something

Hi all, (For Peter) I think I found the main problem with tuning the X and Y axes. I used the registry values of the old system to set the initial parameters for EMC, and goofed on interpreting the accel parameters. In the Galil world, these are in encoder counts / sec^2 rather than units per

I have found a work-around, but wondering if anyone can point me to a better solution. I'm building a second CNC machine (another EMCO F1 with steppers), using the same type of Sound Logic breakout board I used for my first machine. However, I didn't use the charge-pump circuit on that first
