Ok thanks I have cleaned the overflowing PLA and re-tighten the nozzle while hot, now there seems to be no leak anymore. See you around!

Hello! I am pretty new to 3DP and I am using an UMO+. I am writing here because of the following issue. During a print, there is some melted PLA that accumulates on the top of the head, and slowly flow down onto the nozzle. This is no big deal for short prints (its easy to clean the mess when the head is at rest), but for longer prints this extra PLA eventually reaches the tip of the nozzle and badly interferes with the print. See the attached annotated picture. The first thing I thought was to lower the print temperature, but going as low as 184°C didn't solved my issue. Another possibility is that there is some hardware issue: maybe an element of the head isn't screwed tightly enough? What do you think? Best AR
