Hello to all.
I am new to cnc world and encounter some problems with mach3 program, is not authentic but it works. I want to make a flange with 50mm diameter and in its center has hole with 10mm diameter .The aluminum has 10mm thick and the flange 5mm.

I tried to do some work with the 'pick wizard' and 'cut circle' option, but nothing! I can not alter ANY VALUE in editboxes, trying to alter those values after pressing ENTER they return to initial (standard) Values.

Any kind of helo would be apreciated.

TIA
KOSTAS
