I have probably 400 hours on my Centauri Carbon and a good part of that has been failed prints. It started when I was getting the 103 error after replacing my hot end with an Amazon one. I couldn’t even print 5 minutes without getting the error. So I purchased a micro Swiss. It was good for a while. But now this is at least the 2nd time I have gotten a 103 error like 40 hours into a 400 gram print. I had one print that failed at 99.5%!!!! I am printing with PPA-CF at 320C. The max the printer can run at. It fails to do a PID auto tune (completely still by the way) unless I remove the tool head cover with the part cooling fan. Is it possible the hot end fan isn’t adequately cooling when the tool head is installed? I’m really frustrated and disappointed and about to go back to my Ender 3 lol.
