On my taig, if I'm milling a circle and it is not coming out perfectly round, what could I be doing wrong? I'm milling bearing seats and doing both roughing using conventional and finishing using climb cutting (climb is only taking about 8 thou off).
Any tips on where to start looking for the prob?
I'm using the 280oz steppers and a xylotex drive. I've generated the G code using RAMS for the circles.
Thoughts or hints would be appreciated...
