this Rout is a global prompt we set up. Its 8mm deep all the way, it has worked several times previously.

on MV it shows correct, nothing has changed. but the CNC is showing a diferent path. It routes strait throuh the panel and into the spoil board.    Anyone had any issues like this before? or Know what could cause this?   We have tested tool length and all seems fine.  i thought there was a feature on MV that stops tools penetrating the spoil board.
