Neatly done, noticed the sign on the mounting block, know all about loosing balls. The is a newer system that doesn't have that problem as well as covering flexible rubber boots to keep dust out.
lol! YES! I did that cause of the kids. I had it sitting on the table and I was worried they would start messing around with it. Take things apart and see how it works. Newer system? Do you have a link?
this is the round one (dust cover) US $11.4 8% OFF|Machine Tool Flexible Bellows Dust Proof Ball Screw Cover Protector 40mm x 1M can be customized|Linear Guides| - AliExpress The same company also makes rectangular, open bottom rectangular plus custom dust covers I didn't take note of the newer ball screw fittings as I'm not building I already have a good cnc though could do with the dust covers (air duster cleans well but all you need is a chip in the wrong place and it'll either jam or cause a hiccup, had both not nice if your using expensive wood)
Well so on the ball screw to that upper area has a 23mm of surface that the original bearing carrier had to cover. SO the top inner plate holds the screw tight against the bottom plate and the top plate holds the stepper motor with the nut with grub screw tight. So the thought was as i tighten the nut it would bring the screw in to the upper / bottom bearing holder and keep it from slopping around.. That's the goal.
