After using the original Mini for years without any problems, I finally upgraded to Windows 11 from Windows 7. After installing Cura LE 4.13.17, it recognized the printer. It prompted me to upgrade the firmware which I did successfully. I started a print, and during calibration the printer suddenly stopped in place. I cannot get it to respond anymore. There is a quiet, low-level rattle emanating from the housing on the left.
In Cura it now just says “no usb printer connected”, no matter what order I turn things on/off etc. for all versions of 4.x.x that I’ve tried.
After reading this post, I installed version 3.6.20, since that was the last working version for the OP.
With that version, I get prompted to update the firmware again, this time to 1.1.9.34. But I did not update (/downgrade?). When I try to print, I get the error “ Wrong printer detected, starting a print with the wrong printer selected may damage the printer. […]”. It then automatically disconnects the printer. (Yes, I did pick Legacy > Lulzbot Mini 1 during setup).
I am confused and looking for the right way to move forward. Is there a chance I may have caused some damage to the printer through the above process already?
