Cannot connect to repetier or read eeprom

Hello, i've recently updated to 3.1.0 firmware and installed 1.9.2 drivers. Now i have a problem with connecting do repetier-host or any other app via usb. When i connecto to repetier (only bandwith that works is 128000) i have greyed out option for read eeprom and in manual control there is info that 1 command is waiting. After few seconds i get error in log "Communication timeout - reset send buffer block". There is also another error "Error: No Line Number with checksum, Last Line: 0".

I've tried connecting via pronterface or simplify 3d. They only allow to move carriage but when i send some G or M commands (like M501), nothing happens. Just before firmware update everything was working fine.

Also after this update my XYZ calibration didn't reset, is it normal?

Thanks for help.

Same here with problems after updating firmware.

I am using Repetier Server to connect the printer. I've tried different communication speeds and nothing. Also, when its connected to Repetier Server, the contrast on my LCD screen goes very low. Barely able to see the text.

Ok Prusa.. please let us know what is going on. I am sure I am not the only one who has prints to complete and prefer not to use the SD card for them.

I've found a kind of soultion. I've used firmware from this link: https://github.com/thess/Prusa-Firmware It's 3.1.0 with patch for M110 command and it also has hyperfine bed leveling implemented. Now everything works fine for me with repetier.

Thanks!

It fixed the M110 and I'm up and running again.
