All VMCs.... lead screw's thrust bearing preload
Greetings !
How much backlash is allowed for AXIAL play for the lead screws ?
We put new leads crews and bearings (and shim between them) but ... I can still measure 0,03 - 0.04 mm movement on the lead screws (basically all of them do this)
I checked all the other possible places for movements but this seems the only reason why it has such a big play in the system.
