Hi Andrej
I have a Proxxon MF70 that I cnc'ed using a usb controller (4axis mk 1 I think) and generally i have been very happy with it and the software. I have a problem with G2 and G3 circular interpolation. No matter what I do I seem to be only able to make a quarter circle from say x0 to x10 y0- y10 with a 10mm rad. To go from x10 - 20 y10 - y0 10mm rad is mostly ok but going from x20 - x10 y0 - y-10 and
it starts making snake patterns and looses location of 0 datum point. I don't have any problem doing very detailed engraving and linier interpolation. Hope you can help.
