Z Axis lash between ballscrew and platform support

Support&troubleshooting
#1

Hello all,

During the M200 maintenance I noticed that the 4 screws between the Z ballscrew and the platform support are not tightened and so have backlash in Z direction.

Is it normal. (I suppose not :-) )

See on video (with sound):

Yes, it's normal. Mine had a sticker warning not to tighten.

It prevents binding, any backlash that does exist is taken up by the weight of the platform.

This setup in the Z-Axis screw is common to all printers I have seen thus far when using this ballscrew. Do not worry about it.

Thanks for your answers. It seems logical to let a freedom degree...
