Duet 3 MB 6HC CNC Workbee 500/750

Max3D

Greetings,

New user with experience with building a Rostock 3D printer with limited gcode begin/intermediate skills. This is my first CNC build and I jumped into it with a Duet 3 controller with a Raspberry Pi 4 mod B 4 Gig SBC. The hardware on the WorkBee is standard with the exception of NEMA 23 high torque steppers. Why Duet 3 instead of 2? The higher amp stepper drivers and the ability to expand for laser and rotary axis, etc...

I can get to the DWC and the dashboard via monitor and input devices. The DuetPi.zip was used to create the SD card on the Raspberry and I am ready to get started with changing the config from the default 3D printer to a CNC specific config. <= How to do this and or where might I find a widely distributed CNC specific config file to get started? Familiar with Linux Ubuntu and Mac OS.

I am aware of Ooznest's recent change to a Duet 2 controller for their WorkBee and the CNC specific DWC (downloaded), but I doubt that that config and DWC will work on the Duet 3 controller and SBC. I thought I would ask here first.

Thanks in advance...

Not sure you will find a "widely" available CNC config, but there may be someone who can at least share theres if you can't find one in the posts here already.

For the Duet Pi and Duet 3 you should be running the latest 3.1.1 firmware and DSF/DWC versions.

sudo apt update
sudo apt upgrade

if you haven't already.

I assume you've seen these but I'll link them anyway as reference

Thanks for the reply. I have read some of your replies on the forum before I joined, good info. I have read the pages you have listed earlier this week.

I have read that the DWC will alter the site pages according to the config, so that is why I was hoping to find a kind of template config. I have seen some post of members that have done similar hardware configs that I am now working through, but not a similar config with file text available to copy and paste. I'll wait and see what other members can post. I will post my config as soon as I get it done. Thanks again.

So, Ooznest's Duet 2 DWC is a definite no?

I'd look at DueUI which is made by an awesome forum user that allows relatively easy customization of the web interface to suit your needs, thats my plan for making Duet + Pi more CNC friendly at least (only plan, no work done yet)

Cool! Thanks. I'm on it...

I'm not super familiar with it or their changes, but if it's based on DWC2 it may be usable. Since you are using a Duet 3 you should be using firmware and DWC 3.1.1 (latest atm). I don't know if they have migrated their custom version to RRF3 yet.

Thank you...

Just in case someone is looking for a config file and ends up here. I wanted to add that I found what I was looking for here: https://forum.duet3d.com/topic/4669/ooznest-workbee-screw-driven . The config.g from user:Catalin_RO is a good starting point for Duet 3 running a 750/750 screw driven CNC. The post also has some homing files to place in the gcode directory.
