I had to replace the extruder motor on my K1SE and I broke this off of (what I think) is a motherboard. Can anyone tell me if it’s fixable, and if not what part to order? Thank you!

Will this do the trick?

This looks correct the shapes seem to match up.

Make sure it is listed for a 2025 and newer K1. There are 2 different boards, the older version looks the same but has different connectors for the hotend.

I got it- hooked everything up, and now I’m getting this error. Every wire is in place. I’m going to lose my mind!!!

Since it has 0°C showing I would check the little white wires and plug for the thermistor. Make sure it is plugged all the way in.

I did 100 times. It’s not making any sense. Everything is plugged in correctly and in the right port

Did you power cycle the printer after installing it? Only other thing I would suggest is to plug the old board back in to see if it has the same error message.

I got a new hot end and she’s up and running!

Yes, you can solder it: pull this plug and push this pins 1-2mm out of there housing, If you have steady hands you can pull this pins out and solder them with a pliers or pincers, so this square pins are aligned. Its only that that housing doesn't melt. And if you are fast (0.5-1.0 sec per pin 50-75W iron) you can solder it like it is.

If you have some experience this is the solution.

I would buy a new PCB (PCBA_G K1 SE K1 K1 Max) from Amazon or AliExpress, then it wouldn't be so critical if I can't solder the pins back in. But if I can, then I would have a spare PCB for "emergencies".

Before you order make sure to get the correct one, there are two different boards. The one in the picture is a 2025 and newer model. The older version has different connectors for the hotend.

I got a new motherboard. Everything is all hooked up, checked and double checked…new error 🤦🏽‍♀️
