    So i have a set up my pause G Code to move the nozzle up and away so i could change filament. It works sometimes but other times the x axis becomes uneven, one side is higher than the other, causing the print to print either skewed, too low smashing into the print, or both.
    here's my code.

    pause:
    G91 ;
    G1 Z10 F500;
    G90 ;
    G28 X0 F1000;


    resume:
    G1 R1 ;
    G91 ;
    G1 Z-10 F500;
    G90 ;

    I don't do it that way? I use either Prusa color change or a lcd to my robos with filament change enabled in the firmware

    Nothing wrong with that, sounds like possibly you have a binding on one z leadscrew. Might want to start by cleaning and lubricating the z. Then I'd double check your stepper driver and tune if needed

    I'll try that, i do hear a squeak when the z is moving so that could be it.

    i can't figure out where the squeak is coming from and this issue is still happening. could it be a bad motor?

    Usually a bearing, but a motor could do that as well.

    i sprayed a ton of silicon spray inside the motor, squeaking stopped, first test print turned out well. i hope that was the issue. gonna do a longer print and see how it turns out.
