Hello folks . I was just checking my new motors and for wiring them to duet. As i 've read polarity and which coil is which counts. So i have two pairs and want them to plug them in the duet . Are...

Pick two motor wires and short them together, then see if that has made the motor harder to spin by hand. If it does then you have found a coil pair. If not, pick a different pair of wires and try...

do you ever hear the door latch? Posting a video would be very helpful. The output is pretty straightforward. the door isnt latching, or isnt being read as latched. There is a magnetic switch that...

Tks for all your comments. For the door, the magnetic switch is OK, when I open the door, the display prints "door open" !!! And about latch, I've already check the solenoid (26 ohm and the pin goes...

To drive a 4 wire stepper you need to drive it with 4 pins to an h-bridge or the easy way feed 2 pins to step and direction of a stepper driver ic or driver board such as dvr8825 .

The servos use low level signals on their inputs. If the cables are routed next to the X/Y motor cables, those currents through those cables may be inducing signals into the servo inputs. First, twist...
