14. Pre-tighten the two screws that retain the support frame until the Y motor cannot be easily moved. When tightening the screws, please hold the motor with your hands to prevent damage to the coupler.
Figure 13 Pre-tighten the two screws.
15. Check the motion of the Y shaft coupler by holding it with your finger and pushing it forward and backward.
Figure 14 Check the motion of the Y shaft coupler.
16. If the coupler does not slide back and forth easily, please loosen the screws of the support a little until the motor moves to the exact position, which is aligned with the back shaft. Only when the coupler can be moved smoothly by dragging the coupler back and forth with fingers, can the screws in the support frame be pre-tightened.
Check the movement of the Y coupling again, and then perform step 17 until the movement of the Y coupler is very stable.
17. Move the Y coupler so that it faces the front edge.
Figure 15 Move the Y coupler.
18. Make sure that the two grub screws in the Y coupler are against the flat surfaces of the Y motor shaft and the back shaft. Or, please readjust it. Tighten the screws in the Y coupler and reinstall all parts.
