Is it possible to send the axis to a machine coordinate like G00 or G01 sends it to a fixture coordinate. I have a tool changer that will only function close to the Z home limit, when a trip is set. I am manually changing tools at the minute and having to jog to the Z axis position which takes time. It would be handy to be able to send the axis to machine zero with one command, rather than nearly tripping the limit each time I get close. Thanks.

G53 G0 Z0 will send the machine to Z Zero in machine coords at rapid speed.

Thanks Hood, much appreciated.
