[BUG] FW 3.13.2 MK2.5S - Filament sensor not working

[dwprod38]

MMU2S - firmware version 3.0.1

To Reproduce

After flashing MMU2S to 3.0.1 and MK2.5S to 3.13.2 (prusa3d_fw_MMU3_3_0_1.hex and prusa3d_fw_MK25S_3_13_2_7080_RAMBo13a_en-fr.hex) with prusaslicer 2.6.1 --> Warning message: "printer type changed". After clicking button, second message appeared "Old settings found. default PID, Esteps etc. Will be set." And I have filament sensor didn't working -

In system menu/Sensor info : FS bit and FINDA didn't change their value when pushing filament and PiNDA works fine alone.

In Setting/Fil. Sensor menu, we have: Fil. Sensor [ON] F. Runout [N/A] F. Autoload [N/A] FS Action [Cont.]

Back flashing MMU2S to 3.0.0 and MK2.5S to 3.13.1 (prusa3d_fw_MMU3_3_0_0.hex and prusa3d_fw_MK25S_3_13_1_6876_RAMBo13a_en-fr.hex) with prusaslicer 2.6.1 --> Warning message: "printer type changed". After clicking button, second message appeared "Old settings found. default PID, Esteps etc. Will be set."

Filament sensor works fine - In system menu/Sensor info : FS bit and Finda MMU2S change value when pushing filament, PiNDA works fine too.

In Setting/Fil. Sensor menu, we have: Fil. Sensor [ON] F. Runout [ON] F. Autoload [ON] FS Action [Cont.]

After second attempt flashing MMU2S to 3.0.1 and MK2.5S to 3.13.2 (prusa3d_fw_MMU3_3_0_1.hex and prusa3d_fw_MK25S_3_13_2_7080_RAMBo13a_en-fr.hex) with prusaslicer 2.6.1 --> Warning message: "printer type changed".

“printer type changed”: you should never get this message unless you flashed firmware which is for a different printer (For example MK3, MK3S)

The LCD message should say exactly what the type changed to and what the type was before. One of them is wrong.

Yes I understand that used firmware file is directly published from the Prusa3D site : https://cdn.prusa3d.com/downloads/firmware/prusa3d_fw_3_13_2_MK25S.zip

And after unzipping it : there's only hex files for Rambo10a and Rambo13a. None files dedicated to Einsi board used by MK3 were found in this zip... So something wrong with labelling/compiling hex files by Prusa developers.

I've recently discovered printer type mentioned on LCD screen was "Prusa i3 MK2.5" !?!? Something gone wrong on safari browser (MacOS Sierra) with wrong pointing link to firmware (despite clicking on MK2.5S download button: the received file was a MK2.5 version ?!?)...

So, I've decided to downloading and flashing firmware file from GitHub ; https://github.com/prusa3d/Prusa-Firmware/releases/download/v3.13.2/prusa3d_fw_MK25S_3_13_2_7080_RAMBo13a.zip

And everything works fine !!!

PS: After installing Chrome browser, the firmware link downloaded file from Prusa is correct and also works on Prusa MK2.5S ! Conclusion --> Safari browser is obsolete with some corrupted links on prusa3d.com and not working with printables.com: Chrome will be my default browser on my old 13 years old 17" macbookpro...

If you have MK3 then you should use this: https://cdn.prusa3d.com/downloads/firmware/prusa3d_fw_3_13_2_MK3.zip
