The Hackspace bought an Original Prusa i3 MK3 in January 2019.
In 2019 it was upgraded to a MK3S and a hardened steel nozzle was fitted to allow a broader range of materials to be printed.
In 2022 we were donated a second Prusa MK3S.
Induction manual
Here is the user guide referred to in the inductions. It includes a lot of basic how to information that isn't covered in the induction, as the induction focuses on health and safety, procedures and rules for fair use.
In addition to the guide above, you may want to read Prusa's 3D Printing Handbook. The most relevant sections are:
- 3.3 Safety instructions
- 6.3.2 Flexible steel sheet surface preparation
- 6.3.3 Increasing the adhesion
- 6.3.8 Loading the filament into the extruder
- 6.3.9 First layer calibration & 6.3.10 Fine tuning the first layer
- All of Sections 7 Printing, 10 Printing your own models, 11 Materials, 12 FAQ - Printer maintenance and print issues and 14 FAQ - Error messages
