IMO, these commands should be added to the Start Gcodes in CuraLE with appropriate comments. This will make it easier for users of CuraLE to make appropriate adjustments.
Some of my current tool heads won’t even successfully complete the default Start Gcode without adjustments.
IMO, this Universal Firmware is supposed to make it easier on the user, not harder. At the very least, support should create and publish a document that describes the procedure(s) for customizing / tuning tool head parameters.
