Prusa i3 Mk3 use & maintenance

The best printer in the world will eventually drift out of spec far enough to impact your prints. It’s important to master basic care and maintenance for consistent print results.

These notes are focused on care and maintenance of the Prusa i3 Mk3-series printer. I am using the original i3 Mk3 hardware configuration. Most of these notes apply to later versions with minor exceptions.


These notes are based on my experiences with the Prusa i3 Mk3 and Artillery/Evnovo Sidewinder X1 printers. If you are using a different printer, please verify the hardware details are similar.
