Hi, I've made an Autodesk postprocessor (powermill, featurecam, artcam) that works with RRF. It's still a work in progress but so far it works.
The only thing I was not able to remove is the G43H1 at the beginning, I'm not sure if it's post related or cam related...
Canned cycles are dissable.
Arcs works.
I don't have a Duet controlled CNC yet, i'm putting my printer in CNC mode, so if someone can try it, let me know how it works.

I think It would be a good idea if a Duet3 CNC oriented board came out. RRF is great, and very easy to use, but as mentioned before all the boards are very 3D printer oriented.
I would like to have a Duet3 without drivers, thermistor inputs and heater outputs and instead have dir/step outputs and ethercat for the use of industrial servos. Another missing feature is an encoder input for a spindle, needed to do hard threading, and an addon board with isolated inputs and outputs needed for a CNC. Also an MPG input.
Software side, there are no fixed cycles (for now at least), which is not very necessary for a mill (or a router), except for drilling cycles, but it is really used on lathes, also tool radius compensation is needed for a lathe. Otherwise, everything needs to be done on CAM.
It's connected with a 4-wire cable. I'll test disconnecting the PanelDue as soon as the current print is finished.
Well, I actually didn’t find one, nor did I looked for too much. But this got my attention https://www.kickstarter.com/projects/301805155/ustepper
An expansion board with only the encoder would be feasible? I know it’s something I would buy.
It would only need to function when homing Z for the first time and then only when power up the printer.
That way, unless something goes wrong with your bed like a collission, you would never need to home Z.
Sorry if my English is not very good, it’s been a long time since I wrote something on an English forum.
