Hotend Failures
Posted: Fri Nov 15, 2019 4:50 pm
Hello!
I've been running my pair of M2 rE's for my business for a couple of years now, and have a had a repeated issue without my hotends progressively breaking.
The always begin my the aluminum block rotating freely from the center rod. This causes heating issues, and it only solved by really tightening the nozzle. Eventually the hotend breaks at the top stem.
In the Makergear manual it's recommended to remove the hotend and grip both the aluminum piece and nozzle to tighten to prevent the stem from bending or breaking. This of course will not work because of the center spinning freely, and I'm unable to tighten it and achieve proper heat transfer.
I'm now on my 4th hotend having a loose aluminum body. The first three the stems have snapped, and the 4th is now leaking filament around the nozzle despite being tightened completely.
How can I prevent the aluminum body from free spinning? At $85 a piece, replacing a fifth hotend is beginning to get very expensive.
Thanks!
