Re: 972 - ILLEGAL CMD TOOL TIP PT CTRL (ALARM WHEN REACHING G69) - MAZAK 730

Thing is the code at the end of every tool path looks exactly the same (post produced) and they all seem to run fine.
Any ideas?
Thanks,

Before the G69 line, try moving to a safe point (e.g., retract Z and X), canceling tool comp (G40), and then doing the G69.
G0 Z100. ; retract to safe height
G0 X0. ; or home X if needed
G40 ; cancel cutter comp
G69 ; cancel TCP
Sometimes that avoids the illegal state the controller gets into when G69 is issued during or after an incompatible move.
