I'm a big believer in open source, and I do most of my work out in the open. Most of that happens on GitHub, but I also post some of the stuff I do here. Especially when doing something that's not software, I like to make an entry here.

  1. Took another look at the Prusa Mini extruder today. Filament was stuck in there. Cleaned it up. Couldn't find any root cause for these problems.

    I think I just need to pay more attention to preparing the filament properly. You know, cutting it off at an angle, like the manual says, instead of doing nothing and hoping for the best.

  2. Doing some printer maintenance this evening. Nozzle was clogged. Idler screw seemed loose. Must have been a different root cause though, because it's not working again.

    Can't load filament. The extrude motor will run, but it won't grab the filament. Not sure what's happening. Will have to take another look tomorrow.

  3. When you don't have the right wrench, but you have a bandsaw... having some fun while waiting for glue on notebook #5 to dry.

  4. Finally started working on notebook #5! Tried some new things, like drilling the holes into the whole stack of paper all at once, instead of using an awl. Didn't go perfectly, but happy with the result.

    The paper I used is also thicker than usual. Not sure yet what I think about that. Will have to see the end result.
