I recently updated firmware on my k2 plus and it’s failed every print since. Before update it was perfect. I tried to reinstall previous firmware. But it does not boot it up on start up. It’s in the right format and on a small 7gb usb stick. Just doesn’t seem to want to let me return to a usable printer.
It will print a few layers then stops the print and says its not extruding. I went back to just using the reel on the side of the machine but it made no difference.
I went from perfect prints to a completely terrible printer that is not usable at all and the only difference was the latest firmware update, that i can’t seem to roll back
Did you follow this guide on firmware restore?
Hi, the last firmwares does not permits to re-install or downgrade the firmware in any way.
You have to do this. Download the firmware you want to install and rename it with a number higher than the one installed. So, if you installed firmware is CR0CN240110C10_R_202605081127_ota_img_V1.1.5.5.img you have to rename it CR0CN240110C10_R_202605081127_ota_img_V1.1.5.6.img
Put it in a USB drive and the printer will recognize and install it!
Don’t mind about the wrong name of the firmware file, once installed, you will find the correct name in the printer’s info.
Let me know if it works (but it does!)
