Maybe you have not tightened the couplings. Please tighten them.
Rotate the screws as shown in the pictures:

Thank zhangxueyou
I just tighten 4 of them ( 2 sides)
I look better but I still stuck when I cover X-Z and turn on motor.
I try to turn by hand , it is very hard to rotate on one side and another side can easy to rotate

Do you have any more sugguest

Thank

Hello,
j'ai eu le même problème, résolu en mettant un morceau de feuille d'aluminium autour de la tige filetée pour serrer mieux.
désolé mais je ne sais pas l'expliquer en anglais, try with Google traduction

Best regards

I had to enlarge the holes in the top plate for the threaded rods as the hole is the wrong diameter for free movement.

Hi, begizmo
Firstly, you should make sure the assemble direction of pulley is correct. Look at the picture below:

Secondly, as you can see in the picture, the section of the shaft of the motor is not circle, there is a flat side. So you should correcly assemble it to the pulley(Look at the hole of pulley carefully). One screw on the pulley should be aligned the flat side. Tighten all the screws.

Hi, Dominique
Vous ne avez pas besoin de résoudre le problème de l'aluminium. Vous pouvez voir la flèche dans le dessin-il? Serrez les trois vis.
Je espère que vous pouvez résoudre le problème.
Je utilise la traduction de Google. Je espère que vous pouvez comprendre.
bonne chance.

Hi, szeiger
I am sorry for your wasting time on enlarging the hole. We narrow the hole to avoid the deviation formed by the rod, 99.9% of the which are eligible.

Thank zhangxueyou, Dominique, szeiger
I can solve this problem by Drill the hole a little bit for smother and it can easily to rotate

Thank again for all
