What I found with some of the holes is that they were slightly oblong. The x&y was about.012 undersized but at the 2-8 o'clock measurement was perfect. But I will try what you suggested I know I have run-out as I have a router for a spindle.

As far as I know (a new by) my axis are set to at least 2000 steps per. I have my backlash is close about .001 or a bit less.
I measured the cutter with a mic (1/4 inch tool) measured .238 dia.

General Mach Discussion / Double cuts

« on: March 17, 2017, 06:10:44 PM »

I wrote a gcode to do some.5 dia holes and some.25dia. When mach3 cuts 1 hole out it does it again for no reason. I checked my card and it say it does 6 passes per hole where mach3 is doing 12. Why do I have something set wrong. Another thing it is doing is not cutting the holes out to the proper dia they are about .013 undersized. I checked all my axis for Cal and set my back lash but it's still there.

I Am still having noice problems I will deal with that later. When I do a g code for a manual tool change the code reads g91 g28 z0 now how can I write this so the z travels up 1 " and to a desired location to manually change cutter then zero the tool with out using the machine coordinate a but using the work coordinate s
