I could buy another one, but as far as solutions go it's not something that really scales.

There's an app called Octoprint for controlling 3d printers, which runs on a raspberry pi, and supports a webcam and a lot of other cool features. The printers have support for adding the pi board but I figured I would get around to it eventually... Maybe sooner rather than later now. One of the cool things Octoprint can do is detect when it thinks a print is going bad, and then message you asking whether you want to discontinue it or not.
Have the Bear pretty much tuned now, simul-printing at the other end of the workbenches from the stock Prusa. Had some weird vertical effects that I think were caused by some roughness in the motion on the X despite my having used the "good" linear bearings. I undid the X belt and worked it back and forth while putting more grease on the rods and it seems to have smoothed out, and the effects appear to be gone from the prints.

Ordered a Raspberry Pi 4B today along with some other stuff, so I need to set one of the printers to making a case for it. If I can get it set up and working with Octoprint on the Bear I will look into setting up the 3S+ the same way.

Just installed the "Delta P" fan and shroud mod on the extruder. This required printing a new extruder cover from PETG and the new fan shroud out of ASA. This was supposedly designed with the aid of CFD software for better cooling, but the main reason I wanted it was because it gives better visibility at the print head (Bear extruder is particularly bad in this respect with the original fan configuration). Plus, it is one of those rare extruder mods that doesn't require completely disassembling the entire extruder. I will be doing the same thing with the Prusa soon (parts already printed).
