GearHeads Corner

Same setup as my previous post: "I am trying to machine a gear using a shaped milling cutter, not an endmill, but a shaped cutter that looks like a slitting saw. The gear blank is on the 4th axis and the cutter is at the zero Z height (axis of rotation ). The cutter moves across the face of the gear taking multiple passes to achieve final depth. Gearotic does all of this correctly and outputs correct g-code."

In the G code the Y axis zero is set to the side of the blank.

Is there any way to set the Y zero to the center of the gear, on the A axis?

Hi:

Sorry, but the code generator works from a zero point on the side of the gear,  at time of design it seemed the easiest way to
allow one to zero to any blank, and also allowed for easy correction if I wanted to stub a gear some , ( just zero slightly away for
example. ).  Ill post a note to myself to see if I can add a checkbox for zero based coordintes at soem point in future..
