What a detailed answer.
i was actually thinking about plugging the motor leads into the motor outlets.
There are two problems:
I have four outputs for three motors and logically i would connect the outlets to the corresponding outputs xyz. This is my first build and I don't get the y1,y2 thing. Mathematically the surface should be x,y and the z for the vertical axis. as on any of my printers.
even if I'm plugging the motors to the wrong outlets, there should be any movement.
don't understand why there are no first steps for eleksmaker newbies to get it running at first.
