swap the driver between axis, perhaps it built in function to short circuit the windings when powered off

sounds insane, but yes. i can probaly sit ontop of the bed in my 400 without the screws moving. so it sound strange, but i know this is a known issue with ballscrews and heavy z-axis

self driving leadscrews because "physics" is possible. A friction is to low to resist gravity problem.If powered off, this cannot be related to driver or motor, but is a mechanical "problem"

sounds like it, maybe a zero ohm resistor close to the port is fried, or maybe the magic smoke left the mcu chip, less hassle to just replace controllerboard

When a Raspberry Pi boots (models 1 through 4), one or more LEDs will activate. One is red, indicating power (PWR); the other is green and indicates activity (ACT). (There is also a trio of green Raspberry Pi LED lights indicating the Ethernet status, if connected.)
So, what do these LEDs indicate? Well, there's the normal status, when both PWR and ACT LEDs are activated. ACT flashes during SD card activity. Therefore, if there's no green light on your Raspberry Pi, there's a problem with the SD card.
Meanwhile, PWR blinks when power drops below 4.65V. As such, if the Raspberry Pi's red light doesn't light up, there's no power.
If only the red PWR LED is active, and there is no flashing, the Pi is receiving power, but there is no readable boot instruction on the SD card (if present

the Pi usually has a few leds for power and diagnostics. on mine one of them flashes green on "disk activity" i.e' read/write to SD card, could give an indication of dead or alive.
