Hey all,

I'm designing in TurboCAD, then setting up my cuts in CamBam, and then machining via Mach3. I'm typically working with plastic (abs) or wood. My cuts have always seemed to be a little off from what I designed, and I'm wondering if it can be attributed to backlash and if it can be compensated for?

Example: I setup a profile operation cutting bassword with a 1/8" 2 flute mill bit. The desired width of the cut was 0.75" and it machined out 0.735". My typical routine is to go back to TurboCAD and redesign everything making my cuts a little larger to compensate. This takes a tremendous amount of time and it seems like there ought to be a better way.

I'm looking for your expertise on if this can be attributed to backlash and how to compensate for it.
