OCD Prusa MK2/S X-Carriage Parallel Belt Mount. by CO-OCD

Last crawled date: 3 years ago

THIS USES A 16T TOOTHED IDLER PULLEY SET UP AND NOT THE STOCK PRUSA 20T SMOOTH IDLER PULLEY!!!! YOU WILL NEED TO MODIFY YOUR X-END FOR THIS AS WELL. I ALSO HAVE DESIGNED THAT PART.

Want to get rid of that offset on the back of your Prusa where the belt is secured? Ever notice that the X-Idler is larger than the stepper gear? Well, it is, and it causes torque on the belt.
This design removes the 20T smooth Idler and replaces it with a 16T Toothed belt that accurately matches the stepper gear. Torque is eliminated and the belt is now in a 1:1. Now that the Idler is toothed, it will also prevent any belt slippage.
This makes for a very smooth printer!!

If you want to modify your Y-Mount for the belt as well, I have created this too.https://www.thingiverse.com/thing:2770134
