Those nuts either dont elimiate it OR increse system wear overtime with backlash returning. Actually, Acetal (Delrin) has a small amount of flex in it which allows nuts to ride firmly on both flanks of the thread. The split nut design can compensate for wear by applying more pressure with the set s...

You can find the TR8 leadscrews on Aliexpress in 1,2,4, and 8mm pitches. I have a 500mm long TR8-1mm for another project. The quality appears to be excellent. You will need to be able to machine the ends in order to make it fit the rail.

My understanding is missing microsteps is different than missing full steps. Missed microsteps don't necessarily mean a step is lost. Microsteps should not be used to calculate the accuracy or resolution or repeatability of the system.

I hope to be able to get good speed (>1mm/sec) rail performance and simultaneously achieve sub-micron resolution (~0.3um) with 400 step motors and 1mm pitch screw threads (as on the KR20) with very smooth rail performance with minimum vibration impact and no missed microsteps. I don't think that sh...

Orthographic stitches are almost impossible to do without either distorting the subject or having stitching artifacts. In my opinion, the only good methods to make large panoramas are by rotating the lens/camera around the entrance pupil or using a telecentric lens. That being said, try Autopano Pro...

Is this still your horizontal rig? If so, it shouldn't be too hard to convert it vertical.

The SLA printer should be able to do fine threads. Whether or not they will be strong enough is the question :D On my FDM printer, I can reliably make Module 1 gears and GT2-3mm timing pulleys. I usually print in ABS and occasionally with nylon. Both need a heated bed and enclosure. Lens hoods are a...

I use Fusion 360. It's free to most people. The learning curve isn't too bad. Blender is also free, but the learning curve is steep.

That would be hard to say as you haven't given any dimensions for your post :D

It only takes two right angle brackets to constrain a vertical post. 8020 and also Misumi sell brackets for their extrusions. Whether or not they would fit your post would depend on where the holes are located. p.s. You could remove material from the bottom of the post in order to make the holes mat...
