    Hey,

    I have intermittent motor failures for the Y2 motor with the blackbox.

    Here‘s what‘s happening even during regular jogging. As I‘m still struggling to get my Lead 1010 straight, I don‘ really cut anything yet.

    - everything works fine for a while
    - right y motor stops while the other continues (bending the gantry), no error indication (for example red warning light)
    - switch off blackbox
    - straighten y
    - switch on blackbox
    - things work again (for a while)

    I have checked my cabeling, measured wires, checked terminal blocks on plugs etc. Can‘t find anything.

    Any idea what might be the reason or what else I could check?

    Thanks...

    Hi Alex, indeed that was also my first guess which is why I did check the wiring. I have built a few 3D printers so I know my way around steppers. I‘m confident that I have identified the coils correctly and I can‘t find any problems with the cables.

    Turn the current down a bit, the "after a while" still sounds like overheating. Power cycle clearing fault too. Fan is spinning?

    switch Y1 with Y2 at the box and see if the problem follows.

    If it only errors when you connect the motor: See docs:blackbox:currentadjustment [OpenBuilds Documentation] Fault raised by the motor (pulling too much current, short circuit in wiring) as it appears when you connect a motor

    NB! Never connect/disconnect motors with the power on (as warned against in the documentation as well)
