Hi all, The setting of the coordinate system (G53-g59.3) is not working the way I expected, and I am trying to figure out what I am doing wrong. I am running linuxcnc 2.5, BTW.
After initialization and homing, if I issue: G53 G0 X0 Y0 It will correctly move to absolute machine 0, 0. This happens to be starting from machine zero, but no matter where it starts I also issue: G92 X0 Y0 I then set my coordinate systems programatically, for example: G10 L2 P2 X10 Y10 G10 L2 P3 X20 Y20 G10 L2 P4 X30 Y30 And then have an initial move as such: G56 G0 X0 Y0 It will correctly move to the offset for coordinate system 2 (10, 10). If I then run the program to completion, I can re-run it and it will run correctly with the appropriate offsets. However, if I stop the program in the middle and the issue: G53 G0 X0 Y0 It will again go to absolute machine 0, 0. However, if I restart the program above with the three G10 commands, it seems to ignore those offsets when it gets to: G56 G0 X0 Y0 Further, even rehoming and rerunning will not re-establish the offsets, although a complete reinitialization will. I have also tried playing with various permutations of G92 (G92.1, G92.2), in the event the G92 I did at the beginning is contributing to the problem, but that seems to make no difference either. Does anyone see anything obvious I am doing wrong.
