Is it safe to use 230 V AC, 10 A relay shield to turn my Prusa MK3S+ on/off using OctoPrint?

Prusa says the MK3S+ draws up to 120 W. So let's say 150 W of inrush current. $$150 W \div 230 V ≈ 0.65 A$$ An order of magnitude less than a typical Raspberry Pi optically isolated relay shield can do. Is there anything I should be aware of when…

What are the best light positions and directions to highlight the print and reduce shadow and light reflection on my OctoPi cameras?

I'm setting up multiple cameras; I have two running: one camera moving with the bed (static distance to the print) and one camera on the frame (stationary to the printer). I will add a third camera later, an endoscope nozzle camera. However, I have…

Is there a way to send a thumbnail to the printer LCD screen when printing over USB from OctoPrint?

I'm using Cura Thumbnails using a plugin in Cura 5.5. Also, I use the Marlin-based mriscoc firmware on a Creality Ender 3 V2 with OctoPrint using OctoPi on a Raspberry Pi 4. The firmware supposedly supports Thumbnail's preview when printed from an…

Why do two identical Creality Ender 3 V2 printers have a center that is 3 mm off from each other and 7 mm off expected and how to calibrate it?

When pushing the limits of the bed size (235x235 mm) for two Creality Ender 3 V2 printers running the same mriscoc firmware and the same config and upgrades. I noticed that despite using the same G-code for these two fairly identical printers…
