Love the upgrade, I wanted this for the new extruder. The upgrade is worth it even if you don't have the cfs system. The Filament sensor is at the extruder now instead of the back of the machine stopping it from wasting Filament and it now has a filament cutter in the extruder making removal easier. Now my only problem is I can't afford the cfs wich I hope to find a used one one day that I can afford. Read more

Let me start off by saying that I eventually got the kid connected and working. I have made several multicolor prints and it works great. Clearly the K1C was not designed for multicolor. Keep in mind that this is just the upgrade so that you're capable of multicolor, you still have to buy the CFS. I had problems mounting the cutter because the hole that lined up on the head was off. I tried everything possible and ended up having to waller the hole to get it to fit. I was disappointing because I spent 2 hours making sure that it was done with quality. The spring for the poop shoot overlaps part of the plastic and doesn't look like it's really connecting very well, I really wish that this had been done better. Lastly the firmware after you install it is buggy. I have seen several forum posts talk about how the screen fades to black and becomes un usable and you have to reboot. That happened to me. My nozzle wipe is no longer in the same place as it was before and I came up with a solution to get around it but after several resets of the device and reflashing the firmware it is still the same. Because it's not ejecting the excess material out the back it builds up on the bottom. You have to keep an eye on it because it's sitting against a lot of the equipment under there. Don't let your bed go all the way down or you're going to be in trouble. I give it such a low rating because the fitment isn't that great. Also because the firmware to run all this stuff is not that great either. I'm sure that it'll be corrected in future updates but for right now it's not that great. I've had reality printers since 2017 and I love my K1C in its stock form. As a multicolor printer it's not all I expected it to be. I should have left this stock and purchased a different printer for multicolor. I will update as necessary Read more
