Move Z Axis without reWritting the whole code again
« on: February 17, 2015, 05:02:09 PM »
Ok, before we start.... i seem to be having a brain fart.(been away from the machine working for 18Months).
The below code has to have the z axis increment as I machine through a piece of Aluminium
I have chased through my notes from over 8 years and for love nor money i cant remember how to add to the Z axis after each complete cycle.

Also if any one could advise, i am losing a couple of steps in random places while doing the radius cuts, any thoughts?
