I have it set for CV (continuous velocity) motion in Mach 2 which should take care of that, I think. It has a setting that will keep the axes moving as long as the next segment is within so many degrees in direction as the previous segment. I have it set to 10 degrees (the default). I actually can't remember if the setting is 80 or 10, but it is the default from when I had the software in front of me. The servos don't come to a complete stop between segments in any case. When it is doing the Z level work it does a nice smooth full circle until it has to go down in Z. The movement down in Z is a little notchy, but not bad. It is *nothing* like when it goes haywire. Also, it doesn't happen in the same place every time in the program. I once had it go through the whole program without problems.
I really think I have something else going on more on the driver or electronics level. I just need a hint in the right direction. Please somebody help! |
