I’m having a lot of problems with it. I removed the 2 red screws successfully. The blue screw on the left came out, but with, I think, excessive torque required, and on an angle. The hole does appear to be lined up with the threaded hole. The one on the right I ended up stripping the hex head, and had to drill it off. The remaining stud is still there. I cannot pull the heatsink off. I did not remove the extruder feed. because it doesn’t look like I need to, and Creality support says just those 4 screws. Is there another fastener I’m missing? Is there an adhesive behind the heat sink?
Is there a screw on the back of the heatsink that holds the hot end? Basing that on my V3SE and I wouldn’t put it past Creality to do something daft like that again.
Thanks for the help, but I’m going to return this hot end. It’s been a nightmare. Now none of the wrenches they supply will fit the screws holding the hot end in. I don’t know how, but one of the white arrow screws’ head is now stripped. It’s the smallest wrench and it was loose the first time I put it in, so I don’t want to play around with this anymore. I’ve already stripped one screw on the heat sink, and I don’t want to do anymore damage. I’m just going to reassemble it as is, and hope I didn’t screw anything else up.
In case anyone wants this. Here is a video link they sent me after about 4 or 5 attempts with support.
You can cut the head off the one that is stuck since you have new screws in the kit.
Don’t forget the set screw in the back then you should be able to remove the hot end, you should be able to remove the heatsink straight down, this will give you full access to use pliers to unscrew the bad screw.
