I have an SL15 Mori with Yasnac LX3 control and the x axis has the minus on the the top of the stroke and plus on the bottom. This is the reverse of most other machines and makes programing a problem for us. I have a friend that has 3 Mori's just like ours and the X axis are in the normal configuration (plus at top minus at bottom). I need help with finding the parameters to change this machine to be the same as our other turning center or a post processor file for Mastercam that uses this reversed x axis. We can add minus signs to the program but the G2 and G3s are also reversed. Big pain in the rear.
Just program/draw the Part in the opposing quadrant in software. Then use a turret in the opposite quadrant in post. Lower turret instead of upper... and it will post the program you want without any needed changes. It does X- instead of X+ and the G02, G03 moves should be correct as well.
