The original https://www.prusaprinters.org/prints/35611-prusa-i3-mk3s-hemera-upgrade-30 is great. But I found few uncomfortable issues so I fixed it!
Improvements:
- PINDA mount.
- Extruder mounting system is horizontal instead of vertical. It makes maintenance much easier/comfortable.
- It uses 2 screws to secure extruder instead of 1. It stops extruder wobbling completely.
- You do not need to print with supports anymore.
- Cable management.
Software modification for HEMERA needed
For HEMERA, you need to modify E-steps. Visit Prusa Slicer -> printer setup (last tab) -> custom G-code. Do not forget to save the settings as separate “printer”. :)
The custom code
M92 E786.5 // sets your extruder to 786.5 steps/mm
M500 // save settings
