Build Thread - Shariff DMC2 Retrofit to Acorn

eh1524 · Post by **eh1524** » Fri May 02, 2025 2:57 pm

This is the start of my Build Thread for my Shariff DMC2 benchtop CNC mill that originally shipped with an Arduino board but I'm now going to upgrade it to an Acorn board. I'm a very inexperienced operator with limited knowledge so please be patient with my dumb questions.

I've placed the order for my Acorn board and will be starting the retrofit when it arrives. In the meantime here are the current pictures for the existing machine; more to come as I start working on it.

This should be easy going since there are schematics for the components as far as I can tell from the pics.

I received this from the original designer / builder of the machine:

If you are going with another controller, what you need to know is that machine operates with:
5v step/direction signals
10v analog spindle speed control (or PWM)
5v coolant on for relay
normally open estop button
Most hobby level controllers should support these signals,
