Hi, ive got an older milltronics ml-15 lathe with the centurion 6 control. I am posting code to it and I have a problem when it comes to an arc with G18 plane which i believe the control is reading as XZ instead of ZX which is what it needs to be. The manual is unclear to me and I have tried to find the setting in the parameters using proto3 level 3 but i can not find it. The setting I believe I am looking for is PB79=1. I hope I explained this clearly. Thanks for any help.
