Your roothed wheel is back to front. The fastenning boss should be at the end of the shaft. Not next to the motor

I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility. Location Halifax UK...

Then I have to reverse the roothed wheel?

Or turn the printer while the pulley remains stationary

Yes, the x-axis toothed wheel is installed "backward" with the narrowest part of the wheel closest to the stepper motor.  Be sure that you tighten the set screws in the correct sequence as well, one screw tightened onto the flat of the shaft and only then tighten the second.

Regards,

Steve

Roothed wheel = Reversed Toothed Wheel

makes sense to me

Is your printer grinding? Bearings squeaking? Motors smoking?
Step 1) Wash your Steel Sheet
Step 2) Return to Step 1...
