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...
