X stepper barely moving

Hi all
Good to Be here on your site
I was hoping someone could help me
I have an UP plus 2 at my school, on initialising x motor hardly moves, even when swapped to the Z port (Z and Y are working fine)

Has anyone had similar? And is there a place
I could get a schematic to replace the driver chip if thats the issue

Many thanks

switch the x and y on the board, if the x motor still dont move(on y port), and the y motor(on x port) move, then the motor is busted, get a motor replacement. cuz from what you type the chip should be fine. changing the driver is a pain in the ass
