If there is a gap, check whether the synchronous belt is too loose and whether the synchronous belt pressure plate is loose. Check whether the synchronous pulley and the motor shaft are loose, reconnect or tighten them.

(3) Check whether there are impurities on the slide bar of the two-dimensional workbench.
