Cannot Flash my Firmware



  • Just got the Ender 5 Pro for Christmas and it has the "TMC connection error". I did some searching and apparently I am supposed to flash the firmware (my board is V4.2.2). There seems to be several ways to do this, and none of them work for me. I tried the method of copying various .bin or .rar files to the sd card (one at a time) and renaming to firmware.bin. Each time I tried this (11 different times total), after inserting the card and turning the printer on, the screen goes blank, but the logo never appeared - I let it run for about 5 minutes each time. Attached is an image that shows all the files I tried. Any help would be greatly appreciated, thanks!Ender.jpg
