6.0.1 Firmware for Original Prusa MK3.5

Summary

  • Japanese language support (MK4, MK3.9, MK3.5, XL)
  • Phase stepping fixes (XL)
  • Nozzle cleaning repaired (MK4, MK3.9, XL)
  • Acceleration limit restored (MK4, MK3.9, MINI)
  • Stealth mode corrected (MK4, MK3.9, MK3.5, XL)

This is a stable firmware release 6.0.1 that adds one more language and fixes some issues discovered during testing, as well as reported by the Prusa community.

Japanese language support (MK4, MK3.9, MK3.5, XL)

Together with our team in Japan, we have translated the entire Buddy firmware into Japanese. The firmware will be utilizing Katakana. While implementing all the characters we encountered some interesting challenges. For example, Latin characters are typically more rectangular (taller than wider), whereas Katakana characters are closer to square in shape. This required some adjustments in the firmware.

 

The Japanese language is currently available for most of our printers on the Buddy platform, the only exception is MINI/MINI+ which requires further optimizations. We expect support for the MINI in the upcoming firmware release.

To our Prusa community in Japan ハッピー・プリンティング!

Phase stepping fixes (XL)

The developers have thoroughly reviewed the part of the firmware responsible for phase stepping and identified some edge cases occurring during operations such as homing, layer changes, filament changes, and tool changes on the XL.

Now, these specific edge cases are fixed and there should no longer be any skipped layers after the G-code M600 (filament change), and the XL tools should always be parked correctly.

Nozzle cleaning repaired (MK4, MK3.9, XL)

The nozzle cleaning process sometimes resulted in an error “Nozzle cleaning failed” due to a bug introduced in firmware 6.0.0. This bug caused the load cell buffer to "underrun," leading to an incorrect calculation of the distance between the tip of the nozzle and the heatbed. This error has now been fixed, and the nozzle cleaning feature should perform correctly again.

Acceleration limit restored (MK4, MK3.9, MINI)

Firmware 6.0.0 accidentally lowered the HW limit for acceleration and jerk in Normal mode, this release returns the limit to its original value.

Stealth mode corrected (MK4, MK3.9, MK3.5, XL)

In some scenarios, the firmware was not able to switch back to the Normal mode, this is now fixed.
