Well, this is a beautiful sight. Dropped in the replacement power supply and the MK3S is in business! Just needed a few tweaks to get the filament to stick, but now it’s cranking out prints pretty well. It’s faster and a lot quieter than the MK2S. A very worthwhile upgrade.


Great article by a medical expert on the use cases (not many) and accuracy (pretty good, under some circumstances) of the blood oxygen sensor in the new Apple Watch.

Nearly there. Electronics are all hooked up, wires are managed, initial checks check out. Now to see if it actually works…


Heat bed and power supply are installed. My able assistant is taking a nap in the background.


Holy moly… 65 steps later, and the extruded is assembled. Eight Haribo consumed. (Plus a bonus Haribo at the half-way point.) Everything’s looking good so far.


Z-Axis assembly complete! We’re cookin’ with gas now.


The Prusa MK3S upgrade kit comes with a pack of Haribo gummy bears, to be eaten in proscribed amounts at the end of each assembly step. Finishing the X-Axis is relatively easy, so only four Haribo this round.


The upgrade of the Prusa MK2S to the MK3S has begun. Y-Axis assembly is complete. The manual said it should take 2 hours; it took more like 5. But who’s counting? It’s a fun diversion, akin to putting together a really complicated Lego set.

Cherry blossoms!? More like cheery blossoms, amirite?
