I've worked with many E3D hotend clones with M6 heat barriers and they never come loose. But I can't tighten the M7 heat barrier. The hotend starts to wiggle after a few prints. The heat barrier is countered with the nozzle but comes loose in the heatsink. What is the right order to mount it? Do I have to use pliers? Should there be a grub screw in the heatsink to fix it? https://reprap.org/forum/read.php?4,799799,799799#msg-799799 Mon, 10 Aug 2026 18:33:01 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,799799,799917#msg-799917 https://reprap.org/forum/read.php?4,799799,799917#msg-799917 When I screwed the barrier in the heatsink, it felt like I hit the top. Yesterday I shortened the PTFE tube inside the heatsink and it felt different afterwards. Maybe the tube was a bit too long...]]> o_lampe Reprappers Fri, 08 Dec 2017 02:53:41 -0500 https://reprap.org/forum/read.php?4,799799,799904#msg-799904 https://reprap.org/forum/read.php?4,799799,799904#msg-799904
However usually when I switch nozzles and I feel the heat sink coming loose I grab the heatblock and screw it into the heatsink and so far not broken any heatbreaks :D]]> sungod3k Reprappers Thu, 07 Dec 2017 20:21:38 -0500 https://reprap.org/forum/read.php?4,799799,799866#msg-799866 https://reprap.org/forum/read.php?4,799799,799866#msg-799866
