Hi there,

I've currently buyed a new CNC USB controller Mk3/4 and I want to migrate from an old one Mk1. For the drivers, I'm using Wantai DQ542MA.

I need your help in order to connect the new controller to the drivers, at least for the signal wiring diagram. I've carefully read the Mk3/4 manual, but I want to be sure if this is the correct wiring. Please see the picture from the attachment.

Previously, I've used common cathode wiring diagram (for the Mk1). Now, in the previous wiring diagram I've used the common anode. There is any advantage/disadvantage?

P.S. I don't have expertise/skills in electronics, so this is why I'm asking here.

Thank you very much
