4.4.0 Firmware for Original Prusa MINI/MINI+ (Final Release) is out now!  

RE: 4.4.0 Firmware for Original Prusa MINI/MINI+ (Final Release) is out now!

Thanks. I will probably try 4.4.1 and see how it goes. If it still does not work, I will contact support. Thanks for the workaround, though.

RE: 4.4.0 Firmware for Original Prusa MINI/MINI+ (Final Release) is out now!

Hello,

Is it possible to flash firmware to the Mini with no access to the LCD screen? I have it connected to my PC via micro USB and can communicate through the Pronterface console but cannot figure out how to update firmware from here.

Any help is appreciated, Thanks!

Yes, the LCD screen is not necessary. The screen just indicates how far the boot process is, but if you put the firmware files on a USB, connect it to the mini and turn the mini on, it will update the firmware. I'd just wait a few minutes before doing anything else, to  ensure the flash process is finished.

Thanks for the information.

Do you know of any way of determining for certain that the firmware has been flashed?

Every explanation/tutorial I've seen seems to require user input through the LCD PCB, which I do not have. My screen is black and this is the issue I'm trying to fix by flashing firmware.

Using gcode M115 gives (along with other values) on my machine after the update:

M115
FIRMWARE_NAME:Prusa-Firmware-Buddy 4.4.1+4194 (Github) SOURCE_CODE_URL: https://github.com/prusa3d/Prusa-Firmware-Buddy 
...

I found that gcode searching for 'version' on this link:   Prusa-specific G-codes  .   The list doesn't seem to have been updated recently, but it might have some things that could be useful for a 'headless' mini.

Thanks for this! I managed to get the LCD working though by swapping out the buddy board. Not sure what was wrong with the buddy board as it looks fine, but swapping it worked. 

Now I just need to edit the firmware to lengthen the Y axis
