I've come into possession of my brother's 3d printer, a huxley with a melzi controller. I just bought a duet (the .6 version from longcat labs. I'm confused about how to convert the wiring over. The end stop connections on the melzi board have two wires (I'm assuming pwr/gnd). On the duet theres three pins, labelled STP, 3.3, and gnd. What's the stp pin for? It doesn't really make sense that it'd be a blank connection
Also, the motor plugs on the melzi are color coded red, blue, green black (in that order, left to right on the x and y plugs and then flipped black, green, blue, black for the z and e sets. On the duet it has the motor connections labelled as 2b, 2a, 1a, 1b. Which goes where?
