Another thread here has me curious to know if it would be practical to replace the Y axis belt drive with a ball screw drive. I'm not entirely clear on the benefits of a ball screw drive vs belt drive. I'm wondering if a ball screw would reduce backlash on the Y axis of a printer where the Y axis moves the bed, or if it would improve repeat-ability/accuracy.

Some people with the Black Widow end up fiddling quite a bit with driver voltages or even end up swapping drivers to eliminate step skipping.

The move would be from a cheap Chinese belt drive to either a cheap Chinese ball screw ($35-50) or a low end North American ball screw ($150).

The only reason I am considering this is because I would use the belt drive for another project that does not require precision.

I'm curious to know if anyone here has experience with a ball screw axis drive vs the standard belt drive.
