Had it in for 300+ prints after a flathead screwdriver mysteriously stabbed through my last one. Great quality and easy to install

Works very well thank you

Why did you pick this product vs others?: Good quality part, didn’t fit my printer however. One of the hot end connectors is the wrong size versus my board. Will try to modify it so that it will work. Check your printers board carefully, only difference I’ve seen is the hot end connection.

Bought my K1C Max around 2024, gotten a blob that damaged and gave an error code. Using precision flat diagonal cutters, I removed all the glue off of connectors. Then the rest was easy removal and installation. The downside is that the new board has a slightly larger terminal connection for the heating block. Good news is that Microswiss offers adapters for them on their website. Which was good, because my hotend was Microswiss and with a new heater and wires, it all worked together.

If you have a Unicorn hotend you will have problems keeping the connections together. Connections don't match up.

This totally fixed the issue I was having with my k1 max. The nozzle was giving a heating error so I tried a new hot end but didn't work. It was either this circuit or the mainboard that was left to test out and this did the trick. Working pretty well so far. No errors no issues and connections are exactly right.

My original board was killed by a blob of doom breaking one of my cables and when i tried to take the cable ends out it ripped out some of the pins. So i ordered this board, now beware that this is for the new connections, I had to remove the plastic cover on one of the ports and just plug it in to the bare pins. It worked however and it's printing great.

Before you buy this, realize that the 2 pronged temperature sensor wire coming from your hotend is likley incompatable with this board, as some designer decided to replace the standard plug with a slightly smaller connector in it's place. I am totally unsure which hotend this board was made for, but of the 5 hotends I bought for my Creality K1 Max, none of them are the right size for this board. I had to cut up the connector pretty badly in order to get the wires to connect. It does seem to be working after the modifications, but I am floored that anyone would do a design change that was this dumb.
