I'm not sure if the A32 is setup the same as the A20, but on the A20, you can call the live tool from $2 and just use the "K2" argument on the tool call. "T0700 K2" for instance.

This works perfectly and it puts Z0.0 at the center of the live tool. To cancel, just T3000 and a G600.

If the A32 can do it, it would be in the manual under the T commands/arguments. Should have no need for the G140/141...

I do not have an A32 but other Citizen machines.
Does your manual say the G141 is a cancel for G140?
On all others, there is no cancel mode.
Once your done, you issue another G140, putting everything back to normal.
Too, any of the G6XX codes "should" fix them as well.
The use of the "K" option on the tool call line is the better way to go.
Good luck.
