My BT48 will not cut a round circle. I have tried all of the usual things, pinions, adjustments, etc. Even replaced the X axis pinion just for drill.
Recently I was cutting a circle in Corian. The first pass the bit ran smoothly around the circle. On the second pass and all those after that the bit jerks and makes lumpy parts to the circle. It always does this in the same places so that the pieces are very nicely cut out, just not the right shape.
I am just about to decide that the problem is in the software rather than the machine.
Has anyone else had this problem? I am kind of thinking of converting the machine to a rezurection control system but if I did I would like to use Mach 3 as my operating system. Any comments on that?
