I got a new Biqu H2V2 for my Ender 3 pro , since myold hotend started getting unreliable and that was a great excuse for yet another upgrade.

I wasn’t happy with the carriage holder I printed, so I wanted to print a new one. After afew hours of printing, I needed to abandon one part, since it was incredibly messy with blobs of PLA gooped on the print. Since I needed the new carriage mount, I didn’t think anything off it and simply abandoned that part and continued the other ones.

Today, I saw that the heating block is completely gooped up with PLA (see pictures). So now, I got two questions:

  1. How should I remove that gunk? I was thinking o| carefully peeling of everything without the silicone sleeve while the hotend is at a low PLA-bending temp, like 150°C, or 175°C.
  2. What caused this? Flowrate too high (the prints look the part)? Too fast extrusion? Heatcreep?

Thanks in advance. (:

    Nah, don’t worry about it. You used the correct term, which happens to have an amiguous name (you’d translate the German term to “thread-cutting drill”).

    Thanks for the heads up. Is it very unadvisable to leave the PLA in the threading if nozzle and heatbreak have proper contact?

      I think if you can ensure they all thread together without a problem, it doesn’t need to be perfectly clean, but I suspect that will be difficult if there is melted filament in the threads at all
