Likely and easy question about G90 G91 Modal Zaxis <Resolved>

Post by rjtechserv »

All,

I'm confused why the G90 stays active after I've requested G91 causing my Zaxis to limit fault. Likely a setting like parameter3?

I've attached my report and the main folders I use in the Ncfiles folder. The main file to load is the 1759 in the workpiece.

This is NOT a traditional mill its a buffing machine that we G1 the X for linear motion and the Y and Z are top bottom buffs that follow a profile coordinating with the X.

I use D1 and D2 for buff diameters and no real "tool" D or H

I'm going to keep looking at this. Thanks!

Rob

Limits [X 0,-15] [Y 0,-4] [Z 0,-4] So a positive Z in G90 would be past a limit. Normally all negative direction.

I discovered my problem. Using the custom M25 macro interfered. I learned that às well trying to use M26 as another macro. Beware!
