Hello everyone. Had a blob of death on my k1c. The hot end got damaged.
I bought a new hot end, but it is the new version. It burned when I turned the printer on.
Is there any hope to save the printer? The touch screen just says “waiting for printer to initialize“.
Did you change the connector to fit the old board? I thought the old toolhead PCB board and the newer one both had physically different connectors that made using the new hotend on the old toolhead impossible right out of the box. I haven’t seen it or experienced myself but my guess is the toolhead board is most likely dead, main board is probably fine - if the main board was gone the screen wouldn’t display anything and would only light up at best. Because it’s Klipper under the hood, it’s likely trying to establish the connection to all the controller boards inside the K1C - it probably just keeps trying indefinitely, expecting all the boards to respond eventually (which won’t happen if one of the boards is dead).
These are the replacements I bought.
The hotend: Creality Official K1/K1C/K1 Max Hotend Upgrades Ceramic Heating Block Kit, K1 Series Unicorn Quick-Swap Nozzle Kit, K1 SE 3D Printer Hotend 600mm/s High-Speed (Terminal with Buckle) : Amazon.co.uk: Business, Industry & Science
This one connected normally to my head PCB. It smoked just on the printer head, this is why I had some hope the only burned part was the head PCB. After that, I tried to buy a new head PCB. This one: Creality Upgrade K1/K1 Max/K1C/K1 SE Hotend Adapter Plate, Official OEM PCB Nozzle Adapter Toolhead PCBA Original Board Replacement Kit 3D Printer Accessory : Amazon.co.uk: Business, Industry & Science
Swapped it, turned the printer on, and no smoke. But the touch screen just keeps saying the same thing.
I can send a picture from both PCBs, if it helps.
Thanks a lot for the reply! Any help is welcome.
What model of K1c do you have? 2025 or the original K1c. The toolhead board is different on the two K1c as is the main control board. I do not know if the hot end is the same.

I bought it at September 2024. So I guess it is the original K1C.
It still could be the main board. The board may appear to be working correctly but the CAM comms port could have been damaged. Therefore comms to the toolhead board could be compromised.
First try a system reboot - From main menu select “ Reset to default”.
Be careful if you decide to replace the main board, There are two different boards one for the K1 and a different one for the K1c. Check the board installed in your printer before ordering a new one.
This is the board installed in my pre 2025 K1c.
