Carbide3D Nomad Pro 883 configuration
-
Hi all,
I recently grilled the control board of a Nomad Pro 883 from Carbide3D we have at work and as they don't produce replacement parts often (apparently) I decided to go with a Duet 3 Mini 5+. It was also the occasion to make the router smarter and access its progress over wifi, add a LEDs strip and dream about future improvements ! Anyway the thing is now all patched up so it's a good time to share my config.
A few tips if you are trying to do the same:
- Be careful the phases are flipped on carbidemotion boards compared to the duets.
- The card might overheat (at least it does cutting through aluminium) so you will need a nice radiator block inside the electronic case or use a fan (what I did).
- The duet doesn't directly output what's needed for the three phases brushless motor of the Nomad. I used Carbide's McGuillicutty (the stock controller). To make it fit inside the electronic box I had to pierce and thread a new hole.
- The new Nomad 3 doesn't use the same motor/motor controller do you your own research to know what's needed in that case.

Changing tool
This started to work as I was writing this entry so it hasn't be intensely tested. Stay by the CNC for your first time !

Mind you only T0-10 are available in this setup.
