Upgrading my Shapeoko2. Can the Grbl Arduino interface with DM542A drivers?

Hi all,

I’m designing the upgrade of my 1mx1m Shapeoko2 and considering NEMA 23s. Does the Grbl Arduino easily interface with DM542A drivers like these?:




I use them in my Gatton CNC driving 420oz motors

Yes, the Arduino only output step and direction (enable also) which is all there drivers need :slight_smile:

Excellent. Good to know. Thanks. :slight_smile:
