You can use a usb ir receiver, I can recommend FLIRC.

If you do want a robot vacuum, use Valetudo!

I generally calibrate per filament brand and type. Sometimes different colours of the same brand/type behave differently, but usually it’s fine. Haven’t really had issues where I had to change settings between batches.

Make sure you do the calibration on filament you’re sure is dry however… Then, in case you run into issues later just make sure it’s dry first.

I can’t believe how many of my print issues were simply related to wet filament.

Seems like flowrate is too high and/or your filament isn’t dry (or maybe a partial nozzle clog). I know you said it’s ‘fresh’, but unfortunately just because it’s sealed doesn’t mean it’s dry.

I don’t think it’s related to moving the seams…

Do you have any sources for this? Curious about the rpi/broadcom part and tv tuner chips specifically.
