Richard,

I was concerned about this also after reading several posts, mainly on cnczone about eliminating backlash.

So, I have made some supports for the leadsrcrews out of delrin that have a thrust bearing sat behind a 608 bearing. The 608 bearing will support the leadscrew and the thrust will eliminate any end float. The end closest the motor is fixed the other end is adjustable axially.

I also bought an extra piece of leadscrew and made a tap out of it to tap my own anti-backlash delrin nuts.

I haven't fitted these in yet as I'm still waiting for the shafts (that someone is 'aquiring' for me.. ;) ) but I can't see why they wont work??


Nick.
