The G0 is optional if the current motion mode is G0. This will produce coordinated linear motion to the destination point at the current traverse rate (or slower if the machine will not go that fast). It is expected that cutting will not take place when a G0 command is executing.
It is an error if: ยท all axis words are omitted. If cutter radius compensation is active, the motion will differ from the above; see Appendix B. If G53 is programmed on the same line, the motion will also differ; see Section 3.5.12. Somehow the definition and the described motion don't seem to match. Bug?
