Ok, I'm understanding a bit better. My max frequency settings are set at the default 256. I don't have homing setup yet, so the homing speeds are all 0 at the moment.

Ok in General Config. for Mach3 look for Lock Rapid if this is checked uncheck it and try again you may be able to lower the rapid moves with the slider on the Mach3 screen under feed rate slider for Rapid this will help to not over load the motors
