This is regarding a waterjet, but I think a plasma machine would work 
pretty much the same way:

I have a machine that sometimes must be stopped mid cycle and then 
restarted.

I was trying to use a G92 offset to jog to the start position, set a new 
zero point, and then start the cut at the corner of the material.

When the program is stopped midcycle, I'd like to reuse the G92 offsets 
so I can start the program again at the same start point.

But the action of stopping the program seems to be screwing with the G92 
offsets.   Even though they are still shown on the screen, they
are no longer active.

An MDI G0 X0 Y0 goes back to machine home, ignoring the G92 offsets 
which are still on the screen, not to the new zero position formed by 
the G92 offset.

This seems like a bug.

Opinions?

I'm sure I am not the only one doing this, so how do others start over 
after a program stop when a g92 offset has been used?

I'm using 2.6.3 on Debian Wheezy.

Thanks,

Dave
