So I’ve burnt through a few of these in the first year of owning the Nomad. I love the machine but I don’t think it’s acceptable to have the board fry any time the spindle comes under a little resistance, there should be a cut-off in such instances to save the board overloading. In saying that, I can’t fault Carbide3D’s support to date but I will be out of warranty soon.
I’m now determined to do something about this board. The way I see it, there are two options:
- Replace the original board with a custom designed one
- Replace the original board with an off the shelf one
My first thought was simply using one of these controllers:

Issue is I couldn’t get it to work with the stock Nomad 3 motor. I’m not entirely sure what the stock Nomad motor is, looks like a Brushless DC without hall sensor feedback. This controller should still work with it apparently, but so far, no dice.
So the next step was to replace the original Nomad 3 motor with this brushless one.
In testing outside the machine these two work well together and stalling the motor simply activates the controller power cut-off, rather than frying the control board.
It would be great if a new controller board was released to address this issue, I can only imagine how many of these boards they go through.
Anyone have more information that could help in this endeavour?
