heat block leaking. how to tighten?
Hi,
I'm getting plastic oozing (although very small amounts) down the side of the heat block (where the nozzle screws into).
What is the best way to tighten this back up please?
Threadlocker any good to prevent it happening again?

Photos might help. My guess is your hotend is not assembled correctly. The nozzle is not against the heatbreak. Look at the image below.

As shown on the cwbullet's picture: First you need to screw in the heatbreak deeper into the heatblock, so you get (about 0.5mm) gap between heat block and nozzle (green line on picture). Keep in mind, filament is sealed only where heatbreak and nozzle touch each other (threads don't seal).
