3D Printing is a really fun hobby… until it isn’t. When the printer is tuned and working, 3D printing is a very enjoyable hobby. It’s filled with learning and tons of online resources. For a few years my Prusa i3 MK3S+ was working great and then one day during an 11+ hour print I came into my office to find an overnight print failed and I had the rats nest of filament piled up along with an even bigger problem. A big cooled bundle of filament caked to my hot end. Ultimately, I had to recalibrate the whole printer, readjust the SuperPINDA sensor, and basically start from day 1. I have no idea why this happened.
