Title: G00 Problem with my CNC mill
Post by: Richard905 on June 09, 2009, 09:28:05 AM

Hi All:

When I test " G1 X1.00 Y0.5", the X,Y motion is fine, but when I test " G0 X2 Y0.75", no motion with X, Y table, buy right X, Y (2.000, 0.7500) values were still displayed.

I don't know what happened.

Best regards,

Richard

Sounds like you may have the motor tuning too high and the motor is stalling. Mach is open loop so it just calculates and sends out the pulses and presumes the motor got there.

Lower the Vel and Accel for the troublesome axis and see if it helps.
