Prusa Bear mk4 - X axis fails to calibrate after firmware update
I have a few Prusa Mk4 Bear that I updated to latest firmware because they were having trouble locating the bed after the previous update.
The new software did not fix the issue and I was advised the printer requres another verison of firmware specifically for the Bear. I then installed this version of firmware and now the X axis will not calibrate at all on multiple printers. During calibration the head keeps banging to the left side trying to calibrate and times out.
I then tried a factory reset and this did not fix it. After this I tried to select a different printer type as Mk3.9 and then the machine would not detect filament loaded or run bcode files.
How can I get the machines back to working state, I am unable to print at the moment.
Is there a link to the correct version of firmware I should be using or do I need to do someting more extreme than factory reset?
