You need to remove the backlash or you will never get it sorted.

1/4" of backlash sounds like something is not bolted down properly.  Check the coupling is not slipping on the shaft and the ball screw nut is secure in the mounting.

CAMBAM will convert bitmaps to height maps so in theory yes you could do it, I have not tried it so I can not give a definite answer.

The only other way I can think of is to split the circle into segments and then use M codes in between the segments to control the output.

The line can be ' G91 G28 Z0 M6' for a tool change on a automatic tool changer or 'T2 M6' for a manual tool change.

G28 needs an axis designation e.g. G28 Z0 or G91 G28 X0 Y0 Z0

It sounds as if your touch plate thickness is set at 2" thick

Select the item in the menu tree and click on its properties, there will be a list with height, width etc, just enter new values and press enter.

Hi TomR,

are you using a licensed or the demo version of Mach3, the Demo version has limitations.
