Prusa i3 mk3s firmware


I'm keeping getting this error:

avrdude-slic3r -v -p atmega2560 -c wiring -P COM3 -b 115200 -D -U flash:w:0:C:\Users\raxam\Downloads\prusa3d_fw_3_7_2_MK3S\prusa3d_fw_MK3S_3_7_2_2363.hex:i

Using Port : COM3 Using Programmer : wiring Overriding Baud Rate : 115200 avrdude-slic3r: stk500v2_recv(): timeout avrdude-slic3r: stk500v2_getsync(): timeout communicating with programmer avrdude-slic3r: Could not open port: COM3

avrdude-slic3r done. Thank you.

And i have tried, fac reset, reinstall drivers and slicer, tried another usb cabel, change com port, another computer and upload older firmware, but all make the same error.

Any ideas?

best regards

Not what i could see when i tryed to change from com3 to com2, there did it state that com1 and com4 was the only one that was bust at the moment.

I don't quite understand. Are you saying, that the COM port identifier changed under your hands without you having to plug or unplog the device?
