6.2.3 Firmware for Original Prusa MK4S
Summary
- Hotfix for the MMU overcurrent
- Fixed returning to wrong Z position after pause
This is a stable release of firmware version 6.2.3 firmware for the Original Prusa MK4, MK4S, MK3.9, MK3.9S, MK3.5 & MK3.5S.
Hotfix for the MMU overcurrent
A recent supply change of a few electrical components has caused issues during the MMU power-on procedure due to the new components having different tolerances.
We have adjusted the MMU power-on procedure to accommodate this change. The current solution is a hotfix that introduces a small (~1s) delay when powering on the MMU. A more permanent solution will be released soon.
We would like to thank you, the community, for your efforts regarding this issue. Your observations and discoveries have made it much easier for us to locate the problem and focus more on how we could fix it.
Fixed returning to wrong Z position after pause
When unpausing, the printer was not applying the MBL correction to the unpark move.
