    This is a brand new tinyg board that I received 3 days ago. One of the x axis motors stopped working. Not sure but I think its motor 1. The other motor is fine. I’ve checked and rechecked the board configuration and can’t find anything obvious. I’m new to cnc and virtually lost. Hoping someone can help as I may need to return it. Thanks

    Welcome to CNC.

    First recommendation would be to recheck the motor wire connections between the steppers and the tinyG terminals.
    It is fairly easy to push the wires too far into the terminal block, then clamp down on the insulation, not making connection to the leads.
    It is also easy to break the very fine wires it the stepper end.

    If still no success, run a $$ parameter report, scrape the screen to a text file and upload that text to a cloud drive, posting a URL here.

    Next suggestion will be to swap leads at the tinyG end between the two (as I read it) X to see if the problem appears too be tinyG or perhaps a motor motors.

    Also, describe what you see on the tinyG LEDs when you power up the board.

    I have swapped leads and tried a new stepper motor but Motor 4 still wont run. Blue power lite and red PWM. Here is the file. Sorry if I uploaded this wrong. Line number: 0

    The motor $_pm=2 looks good on all 4 motors.
    All four motor LEDs (green) should flash on for $mt (= 2 seconds) on startup.

    Sounds like you might have a bad M1 driver, send a message to https://synthetos.comcontact-us and they will suggest a replacement strategy

    I have the 4 green LEDs for 2 sec. I just emailed them as per your instructions. Thank you.

    How long before I hear back from support? Any way I can know if they even received my request? Thanks

    Should I just order a new tinyg? I have returned the defective one and other thn their email giving me the return address, I have had no response from them. Can you advise what I need to do to resolve this. Thank you.

    If you received a return address, I think safe to assume you will get a replacement back.
