Is there a command to make the machine ignore all Z values starting at a certain place in a 3d file? I want the Z to stay at the last specified value without having to go through and manually remove all the Zs.
You may have already run this job, but here's something for future reference:
depending on your machine/control there may be a Z axis inhibit button on your
machine op panel. Do a program restart at the block before you want to turn off
your Z, and press the button.
I you do not have a button on your control panel, you could also locate the PLC
device for the z axis inhibit and force it high (need to be able to access your plc I/F) after getting to your program start point.
Some controls also offer a G10 that not only writes parameters, but also can
write to PLC registers.
Just some things to try if you ever find yourself in the same situation.
