Just a quick update to my circle cutting problems.

I basically have not idea how or what fixed it but the changes I made were:

1. Fitted a SmoothStepper

2. Fitted shielded cable for the spindle motor from a junction point to the Spindle motor.

The smoothstepper has allowed me to increase my resolution from 143 pulses / mm to 259 without sacrificing speed and the shielded cable was what I should have fitted first time around.

Thanks to all who responded, I have been cutting perfect circles all weekend.

SteinarN - I am coming in late to this post - it appears finished - but - YES - Mach 3 supports backlash compensation. You cvan measure your backlash on each axis and put the data in Config/Backlash. If you turn backlash compensation on, the Mach 3 will allow for the backlash every time your acis changes direction.
Not me driving the engine - I'm better looking.
