Drifting G71 return point on ID boring HAAS.
Attempting to bore a .750 hole .66 deep. the end of the bore doesn't touch anything so the finish is unimportant.
when i use a tnr value of .008 in the controller somehow i must have made an error with cutter compensation because the retract point drifts in Z from first to last pass, as well as my comp off move cuts too deep in z before retracting to the correct location.
I've tried a W0. in both the comp on and off lines but it seems to have no effect. type 2 for tool direction. when i put 0 for the comp value the issue is resolved entirely but I'd like to let the program comp the chamfer at the front of the bore
scratching my head here. the haas video about g71 showed a different comp off move from their workbook we have...
my backplotting software doesn't show this so I'm lost to what i did wrong. any help is appreciated!
