If I’m reading your comment right, you might be talking about gauging for inspection purposes, but that’s not what OP has here. I’d call it more of a printer calibration block.

Mars was full so my ancestors had no choice but to come here :(

A drone operator usually is not standing directly under the drone, so no. Or alternately, the drone if probably further away from you horizontally than vertically during most of its operation.

One interesting thing here is that, for a given altitude, the antenna gain will be higher the further away the drone is.

“Tech” is a conflated term. The way I read OP is that they don’t want their cars main user interface to be a smartphone app. Doesn’t mean the car can’t be technologically advanced.

Personally, my brain manages to filter out anything with a leading underscore (I don’t know the origin offhand, I think some system I worked with at some point used those on files that I knew I didn’t care about). So when coworkers use leading underscores it slows me down a bit.

It does work though

Tangential, but Blind Guardian has one

I suspect an electrical issue on the motherboard.

• What happens if you swap the bed and hotend thermistor, and/or plug one of your reference thermistor into the bed input?
• What is the open-circuit voltage on the signal line of the hotend and bed thermistor inputs?
• What is the short-circuit current of the same?

If you see differences in those last two points, that is a clue that something is messing with the divider circuit that the thermistor is a part of.

23% is really just the bottom range of what your dryer will report. My dryer is 15%. Who knows what it really is below that, and whether those numbers are even accurate?

But after a day of drying at 50C you PLA will be bone dry regardless of what the dryer reports.

That one and “FAFO” in its various incarnations can take a break for a bit, IMO

I think you are looking for a caliper

But it might be more fun.

Or more tedious 😀
