Pocket hole operation problem
« on: October 11, 2020, 12:26:42 PM »
Mach4 - using the same g-code I used in Mach3 for a pocketing operation in 1/2" aluminum with a 1/8 bit.
Zero the Z axis and the DRO reads 1.622 which is the thickness of the block plus a 1 inch retraction.
All good so far. The operation has a clearance place of .02 inches and a depth of cut of .05" with a final depth of .55". After each completed plunge, the Z moves up to 1.3 inches. There is nothing in the G-Code that tells it to move more than to the clearance plane.
Any ideas appreciated!

So it turns out that if you are running the Tangential screen set it does not matter whether it is active or not. The spindle lifts at each corner as defined
by the settings. Mine was set to 1.3 for testing purposes. Set it to zero and all is good.
