    Good afternoon all,

    I had a pretty bad nozzle clog and I managed to get it all cleared. That was fun. Now when I try to home my printer, it goes to the right side and makes this horrible noise. I believe it is not registering that its gotten to the side. The only way to stop it is to power down the machine.

    In my efforts to fix it, looks like I messed something else up. What do you all think?

    Sounds like the X axis limit switch is not triggering.
    Don't have an FlashForge to look at and am not familiar with them other than a casual glance.

    Can't hurt I don't suppose. There should be some sort of limit switch that tells the printer when it homes each Axis. One for X, Y and Z.

    So make sure the wires are still connected to the switch and that the print head is moving over to where it would trip the switch.

    Hopefully that image confirms what you thought.

    The grinding noise is the stepper trying to step past a physical blockage.
    It can't so it drops steps (and that sound is what it makes when the stepper drops steps).
    I am guessing that is the the X home it is going towards and the X home switch is not activating so it keeps trying to drive it further.

    So, replacing the parts you suggested would solve the issue?

    If you can disassemble it enough to find the switch it is trying to trip, you can at least verify that the switch is not mechanically broken and that it is not disconnected (wire knocked off).

    You can even try manually tripping the switch when it starts to home and see if it immediately stops moving on the X when you do that.
