@dc42 That's great news! I appreciate all the work you and your team put into the Duet! I have 8 FFF machines that I use to fabricate parts for my company. Last year I bought a Duet2 Wifi for my printer at home just to try it out and see what it was all about. The next day I ordered 8 of them and switched all the machines in my shop over to the Duet2Wifi. I'm pretty sure I've tried just about every MC option available. The Duets are hands down the best and most reliable. My machines run 16 hours a day, six days a week. Its been over a year now and I have never had a single issue with any of the Duet boards.

Disregard. I figured it out. I was testing the Workbee CNC DWC on this machine yesterday before I installed it on the actual CNC machine. It installed RepRap2 on the board. When I put RR3 back on it the issue went away.

This is great! Thank you! Will this CNC screen format work on a 7i Panel Due?

@jay_s_uk Sorry.. M280 not M208

No. If I manually enter the M208 Commands, it throws the same error

I'm getting this error when homing. It was working fine before. Yesterday I set it up to do sensorless endstops for X Y, and it started with this error. I returned all of my sys files back to the original and it was still happening. I reloaded all the firmware and all new sys files...and its still happening.

I checked the wiring, its all correct, BL touch does its usual pin cycle on powerup. Any help would be greatly appreciated. Here is my current config settings.

What are the differences between this new CNC DWC and the Workbee DWC?

@R4ffers No not really. 10x simpler than setting up a printer. Just setting up the config and wiring up the steppers is all it really took. I set it up with sensor-less homing, which I haven’t done before. That took me a little over an hour to get figured out dialed in. Overall it’s really simple for a 3 axis.

The workbee DWC is very simple and straight forward.

I got my mill up and running on my Duet3 with the Workbee version of DWC.

What is the best post processing option from Fusion360 to use with Duet?

Thanks. I’ll check it out. Are there so few people using these boards for anything other than 3D additive applications that a CNC focused version isn’t worth the development cost/time?

Duet is such a great controller design and DWC is so intuitive compared to anything outside of the crazy cost of commercial machines/software. It’s far superior to GRBL, Smoothie, BOB and even Mach in my opinion.

For small business that can’t take on the investment of a small scale commercial CNC , Duet would be the best option for anyone building a machine themselves or converting an old school mill to NC. I’m just surprised there isn’t more interest for it.
