Hello!
I just bought my Ender 5 Max. After adjusting the belt tension and updating the firmware, I finally got some decent prints.
I’m printing with PETG, and two days ago, the hot end got completely clogged. The PETG had glazed over inside.
I unclogged the hot end as best I could, but it clogged up again during the first test print.
I ordered a new hot end from the Creality spare parts website, but in the meantime, I’ll lose a week for delivery :-/
Is there a way to use a different hot end (by which I mean the cylindrical part where the nozzle screws)? Like a K1 hot end, for example?
I’ve had four of these hot ends (and one extruder) fail for one reason or another in just the last month. When a third party comes up with an aftermarket for this printer, yer damn right I’ll be switching to it.
Three began leaking where the heating element connects to the heat break, just oozing out of that connection. One could be salvaged, two were completely entombed in goop and the wiring damaged. The silicone condom traps the leaks and starts shoving it back up and around the hot. Huge mess.
One also jammed for no apparent reason; just went to swap colors after a job and it won’t feed. Can’t get a needle down through the block. Haven’t had time to try to disassemble that one and see if it can be cleaned out.
Amazon sells them now, which will save you the month waiting for them to arrive from Chyna. I was down my entire first month waiting for parts from Chyna too. (Amazon also has a fantastic return policy… just Saiyan. 
)
As I know you can replace original hotend with k2 hotend and also use k2 nozzels. I will try this in few weeks.
