PS - I've just discovered that LinuxCNC supports an extended version of G10 in which P0 is allowed and means use the current coordinate system. That's not currently supported by RRF, but I can add it in the next 3.4 beta release.
@erfreuterstudent
that's a premier for me too, but we'll try.
With a toolchanger you could poll the diameter of the current tool in tpost#.g by using M118 S2 P"toolnumber"
Now the arduino reads this message and sends the aquired data, but here it get's shady for me. It is easy to receive messages and display them on DWC, but reading data into a global variable is unknown to me. I tried it over I2Cport, but fell into the same dark hole...
Maybe @dc42 has a solution now?
@dc42 thank you. This is very helpful. I will give it a try. It seems the assistant you have asks the user to adjust per a given thread pitch. I do like the craftbot method of just continuously probing and letting the use make micro adjustments to see how close they are getting to the desired positions.
Perhaps once we have SBC capability on the Duet2 we can make more elaborate wizards and guided assistants.
The only thing that exists in the slicer related to starting/ending a print are calls to macros

That's correct, create a new axis (e.g. U or C, it doesn't matter which as long as you are consistent) for the extruder angle control using the M584 command. If you need to home it, connect the homing switch to the E0 endstop input.
Has run into same issue with E-axis today. Was trying to set up print resuming after power loss and found out that RRF is ignoring G92 command in the "resurrect.g" file.
Basically, what happens is when I resume printing after power down the print head goes over the print and then it starts extruding all the way from 0 to the value that has been stored in "resurrect.g".
