I have a problem when cutting circles about 25mm in diameter.
The problem is the circle has a small flat spot on one side.
I have tried slightly different size circles 20mm & 30mm and it appears on all of them.
I am using VCarvePro to generate my G Code to a Proxxon MF70 CNC controlled by Mach3.
Not sure whats causing it so any help is appreciated.
Thanks
Jason
