is this bad?

[rocky glade]

Just opened my cr10s hotend cover and saw this. Is this filament seeping back thru the hotened?

AI Help

It's difficult to tell without more information or a closer look, but it's possible that the filament is slowly seeping through the hotend. This could potentially be caused by a variety of factors, such as a partially clogged nozzle, incorrect temperature settings, or a poorly inserted bowden tube. You should clean the hotend thoroughly and examine the nozzle for any clogs that may be present. If the issue persists, you may need to adjust your temperature settings or check the bowden tube for any damage or deformities.

Yes, likely

Depending on how long this has been there, it can be a major or minor problem

But regardless, a leak is a sign of trouble. It may cause you grief because of clogs and friction

I recommend you to hot tighten the hotend to prevent any futher leak.

1. heat the hotend to a standard printing temperature (I do it at 210°C)

2. Once temperature reached, with the correct tools, clamp the heating block so it won't move while you tighten.

3. Tighten (you should at least be able to make a 1mm turn more than if you tighten it cold). If you can't tighten it any more don't force too much to prevent breaking the nozzle (cheap nozzle)

4. you are done
