[In evidenza] 5.2.2 Firmware for Original Prusa MK3.5  

5.2.2 Firmware for Original Prusa MK3.5

Hell all;

We are happy to announce the release of our new firmware for the Original Prusa 3.5 printers; 

Summary

• Bed Level Correction
• Support for Revo hotend
• Mesh bed leveling fix (7x7)

This is a stable firmware release recommended for all users of the Original Prusa MK3.5. It brings full support of Revo hotends, allows to perform bed level correction and addresses mesh bed leveling issues.

Bed Level Correction

This feature, originally introduced on the Original Prusa MK3 as an addition to the Mesh Bed Leveling (MBL), allowed experienced users to further compensate for any imperfections on the heatbed. The bed level correction gathers user data on how to adjust Z height in four directions around the plate (front, left, back, right) and then changes mesh bed leveling values through linear interpolation.

In most cases, this manual correction is unnecessary as MBL will handle compensation automatically. To adjust settings visit Control -> Bed Level Correction.

Support for Revo hotend

This release provides full support for the Revo hotends. By default, the printer expects a stock Prusa hotend during the initial self-test. If this procedure fails, then the user is asked to verify the hotend setup and adjust the settings.

If you decide to change your hotend on an already calibrated printer, you can adjust the settings in “Settings -> Hardware -> Hotend Type”. It is recommended to rerun the “heater test” to ensure your new hotend is performing correctly.

Mesh bed leveling fix (7x7)

The previous firmware release included a bug reported by the Prusa community on GitHub. While performing the MBL, the printer used only a 6x7 point grid and omitted the left side of the heatbed, which in some cases resulted in uneven first layer height.

We would like to thank everyone who contributed to fixing this issue #3772.
