Have you checked to see if the main hot-end cooling fan is working while you are printing? I've been have the same type of issue with my CR-10. I started to get heat creeping up the Bowden tube and clogging it. I've tried a few different things and tests some small prints and found the the hot-end cooling fan is not turning on during print. I have tested the unit and when I do a normal preheat the fan is on a t all time. once I try to start a print the fan turns off. I've tried to turn on all the fans manually in Cura to no success. I've been using Cura for a couple years now and just started having this issue in the last couple months. So far I've had to replace my hot end because the original one got so badly clogged with plastic I couldn't fix it. I done' know how many nozzles I have clogged and Bowden tube I have gone through. Going to be running a new test and turn the fan on manually to see if that work. I'll keep you informed I'm running a Creality CR-10 V1 and using Cura 4.8
