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.
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.
Industrial cnc systems show real-time position of the movements. What I don’t know is if that position shown is read from the encoders or generated from the gcode. The control definitely knows encoder position off all axis and can make corrections.
I used S3D for two years, I'm using superslicer now, and I'm very happy with it and get much better quality parts than S3D and CURA. CURA is slow. The only feature I missed from S3D is the ability to easily removed unwanted supports, appart from that, slicer works much much better.
Hi! You should provide your specific hardware, movement kinematic, and extruder type before anyone could help you.
@Phaedrux said in Problem with babystepping V3.01 RC10 and DWC 2.1.5.:
So you're saying that if you set the baby stepping once during a print it is being applied again on the second print?
Thats right. It started since the V3 release. I forgot to mention that every consecutive print re home all the axis. I have a bltouch 2.0 and I get excellent repeatability when homing so I don't think thats the problem.
I'll try RC11 next week and test if there are any changes.
I have a problem sin V3 release, it did not happen with 2.05. When I start a print, if I adjust first layer height with baby stepping, lets say 0.1mm closing the gap between bed and extruder, and the print finish or I stop it and start another, the new job takes into account the previously set distance and re apply again, many times making the extruder touch the bed and I need to increase the gap the same amount I decrease it the first time. Im on V3.01 RC10 and DWC 2.1.5. Duet 2 ethernet.

Fanuc post should work. I made one for powermill (it’s here on the forum). David fix the firmware some time ago so G1 and F commands are maintain until a change in one of those, which was the primary difference I found with industrial cnc controllers.
You should disable fix cycles in post or write the program without them (I don’t know how fusion works), since RRF doesn’t support them.
@deckingman said in My multi input, multi material, mixing hot end:
@fma I don't know what the boiling point of printer ink is, but I'll bet it would likely just vaporise if you tried to inject it into the melt chamber at circa 200 deg C.
There are liquid masterbatches, they are used in the plastic injection industry primarily for PET and PC resins, so they resist 300° C easily. They get injected with a peristaltic pump if I remember correctly, but you need a pump per colour.
Solid masterbatches won't work unless you have a very long screw, so I think not even pellet extruders might get consistent colors with that...
Hi, I want to build my own injection molding robot and was looking the best hardware to do it, but I will use external drivers.
Will a duet2 or a duet3 board without on board drivers, aim at controling industrial servos only be made in the future?
I'm also considering machinekit with a beaglebone but since I become very familiar with RRF I would really preffer to use a Duet family product,
@bluedust Hi, I have 801,81 at 16x interpolated to 256x.
