UCCNC stays in incremental mode during the Z axis moves and cuts a 3/8" deep pocket (should be .250 deep.
Also the machine returns to Z.625 at end of program, should return to Z1.
I use a variation of this program daily on Fanuc and Maho controllers.
There's a reason I like to make Z moves in absolute but I want to keep this short.
Thanks - also I'm a "newbie" with UCCNC, just finished G0704 conversion about a month ago.
