Hi @labsud,

I am trying to build my own CNC machine as a semicustom WorkBee design using the Due and g2core.

I was thinking of designing my own from scratch but found your work here instead, which looks like an awesome starting point.

I am planning to use inexpensive TB6600 drivers which require 5v signal levels. Due spits out 3.3v and although the TB6600 I intend to use may be tolerant to 3.3v inputs, I've read around that it's not good practice.

In your design I haven't seen any level shifting components (but you have a driver power config 3.3v-5v?) so I guess you went with the "drivers will be ok" mindset.

Did it work for you? Otherwise I might want to tweak your shield to add level shifting to the motor control pins.

Thanks
Nico
