@Perplexed I've updated the CNC wiki page with your suggestions, and a few other notes: https://docs.duet3d.com/en/User_manual/Machine_configuration/Configuration_CNC
It would be great if people could share their CNC configurations, or links to them, in the sticky thread: https://forum.duet3d.com/topic/19388/repository-for-cnc-config-s-and-macro-s
It's a bit bare in there! Unfortunately there is no 'wiki-like' post mechanism in NodeBB, as far as I'm aware. That's what the Wiki is for.
