I’ve had a Creality CR-10 MAX for about a year and a half at this point. I bought it on sale in early 2020 when I had big project ideas that wouldn’t fit on my workhorse Prusa i3 MK3S, so it’s fair to say I bought it for the large size for the price point and not the build quality or feature set. However, I’ve never really liked it, so now that the Prusa is working really well with Octoprint, the box, the cameras, and all of the other projects I’ve documented here, it’s time to move on to the CR-10 and get that one working well too.

After buying some cheap USB boroscope cameras to use as an actual boroscope for home renovation projects, I decided to buy one with a flexible cable to mount near the nozzle of my Prusa i3 MK3s to get a time-lapse of the nozzle during the printing process. Watching the first layer closely during a print can show failures early, since most failures are due to bed adhesion or other first-layer problems.

I have a Prusa i3 MK3S 3D printer, and I use it for many projects I post here. I want to know roughly how much power it consumes while printing, to get a feel for both the peak power consumption of the printer (to, say, size an off-grid power system) and energy consumed for an average print. I know the cost of filament is pretty low for most projects, but I don’t know the cost of energy (or wear on the printer).

In this project, I setup a proper OctoPrint server for my 3D printer, and integrate it into the enclosure I already built. I also add some RGB flair to make it look nice, and set it up to integrate with Home Assistant. I’m very pleased with the results, so follow along for how I set it up. Building the Circuit Since I want to use WS2812 LED strips to show the printing status, I need a small circuit.
