Jerky movement
« on: June 01, 2010, 05:48:09 PM »
   Hello,
I have a problem with machine controlled by Mach3 software. When you run a NC file, the movement of the machine along a curve is jerky. On the straight lines is smooth. The NC file was generated from ArtCAM. I tried postprocessors for arcs and for straight lines, but the result is identical. The attached is a sample NC files and screenshot of motor tuning (everything is in millimeters.).

    Would you help me solve this problem?

As a test try with the circular pocket wizard and see if things are jerky.

Also verify that the machine is running in G64 mode(CV) and not G61mode(exact stop). Normally in the header of the Gcode file it would set the mode correctly. But I don't see it in yours
