Please help me determine if my plasma table is jerky because of the mechanical design or motor tuning.
The problem is when making rapid small movements the torch holder shakes too much. Experimenting with motor tuning in Mach3 helps but hasn't eliminated the problem....unless I just havent found the right tuning yet.
I am using rack and pinion direct drive.
Rack has 5.1 teeth per inch and the pinion has 16teeth on 1.125" diameter.
Is this combo going to inherently give me problems or should I continue to play with motor tuning?
Thanks, John
