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. It took time, and some trial and error, but I've finally created a working slicer profile for NonOilen. With that in hand, and my printer back under control, I've restarted my effort to create a physical product. More on that soon!

    And since it's certain that I'll run into problems sooner or later, I want to be better prepared next time. Hopefully these books will help me step up my game!

  2. I found out yesterday that my newsletter sign-up form hadn't been working in Chrome. For months. Of course I had tested it regularly, but in Firefox.

    Well, now I know more about the pitfalls of cross-browser compatibility, and you can finally sign up to my newsletter. If anything's not working, please let me know!

  3. I've been busy printing NonOilen. Experimented with settings, to try and print it without adhesive, but no luck due to warping problems. Maybe it's possible with an enclosure.

    Happy to report that the crash last week doesn't seem to have caused any damage on the printer, as far as I can tell.

  4. I crashed my printer yesterday! Into the screws at the back of the heat bed, that serve as a stop for the steel sheets. No visible damage. The nozzle just flexed out of the way, but I don't know if anything was knocked out of alignment.

    Lesson learned: PrusaSlicer will happily let you drive the nozzle into those screws, if you tell it to. Even though it usually throws an error at you, if it sees a path that is out of bounds.

  5. Now that my printer works again and all my problems are solved forever, I'm back to getting the NonOilen to work. I made good progress, but am having some trouble with warping.

    I'll post a note about printing NonOilen on a Prusa Mini, once I got it working sufficiently well.
