.125dia tool cutting a .230dia ID will leave you .0525 move if you are starting in the center of the hole and moving to the edge I dont know if you are saying that cuttercomp is not working correctly but I have used it for this application and it works as I think it should.

Greetings; Lots of editing to no avail, but I believe I have a clue to the G41-42 problem. The preset radius is for a .230" diameter circle, but if I use a .125 mill, it errors out and will not load the code. So, switching to the G41.1 Dnn.nn mode, the error is triggered even by a g41.1 D0.0000001. My machine, I don't think, can even make that small a move! Now, the code output by gcode-tools places the bit into cutting position to actually start cutting the circle, so it looks as if I need to first place the cutter at dead center, then move to the starting offset, which with a .230 OD to the cut, and a .125 OD to the mill, should leave it .115" to move from the center to the y=0 relative, x=compensated relative offset. Am I making any sense here? It isn't to me. I think it should take place at any point in the motions where it can detect left or right edge, positioning to do dig cuts, or climb cuts. Waiting to apply the correction as a circular cut actually starts sure is a PIMA, and wrong to me. Can anyone explain why, and then how to fix it, since without the comp, a .230 diameter cut turns into a .345" diameter cut because the radii of the tool gets added all the way around. Thanks guys.
