Hi- I'm new to the system.  Trying to turn a simple diameter using the mach turn wizard.  I am in diameter mode and absolute positioning.
I set my clearance to 0.012", but the wizard doubles the amount to 0.024" in the G code.

EXAMPLE   X start is 0.755  X end is 0.725  Clearance is 0.012

When the code posts it shows the X position as 0.779 instead of 0.767

When I run the program it also cuts double and my part ends up at 0.695
It's clear that X is travelling twice as far as it should, but I can't understand why.

Thanks in advance for any help

When in Dia mode your clearance in code would be represented by double the value you enter. It will only move the distance, on the X axis,  you enter but on the Dia it will be twice the value.
Maybe I am misunderstanding what you are meaning ?

Hood,
Thanks, I finally  came to that conclusion- maybe in the coding it is adding the clearance to both sides of the part.  I was still getting the double cut error, and after trying about everything by trial and error, I found 2 issues
1.  If Jog is turned on it wants to cut double
2.  If backlash compensation is turned on it seems to double the backlash value of X when in diameter mode.
Once I turned those 2 items off I was getting cuts accurate within the range of the machine back lash.   My next plan ( after resting my feet) is to cut the X axis backlash setting in half and see if that works.

Are you using an external controller or the Parallel Port?
