0.9º XY motor replacement for greater accuracy?

Recommended Posts

Has anyone tried replacing their XY motors with a 0.9º stepper motor? I found one that should fit (or require very little modification) but wanted to know if anyone has already tried this? My goal is to increase the accuracy to be able to hold +/-.001" (0.025mm) tolerances on parts. I usually print at slow speeds (20-40mm/s) so I'm not worried about the loss of speed.

With this sort of accuracy there are so many things that have an effect and other things I would look at getting right first.

PID bed control

Constant room temp with no breeze's from aircon.

Direct drive, Bowden is no good.

I would even change the main board to something like the duet3d as it has newer drivers that can go to 256 micro stepping.

Also need to make sure your bearings are good quality and don't have bent rods.

Depending on your printers age, there is a newer belt and pulley profile which gives smoother motion.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
