Hi Folks,

Not many threads on this topic, and not for a long time. Maybe someone can lend me some wisdom.

I recently purchased an old D&M 5 CNC Lathe.

I converted it to run Arduino Due flavoured TinyG, with the origional stepped drivers, and was pretty dissatisfied.

So I converted it to Centroid Acorn, with TB6600 Steppers and it's working significantly better.

I am trying to figure out if I can control the existing DC spindle motor driver which has a 0-10V input, with the Acorn 0-10V Output.

The question I have is of DC common isolation, is it safe to connect the acorn to the dc drive?

Happy to discuss and share what I know so far.

Cheers.
