Z-axis calibration after power failure
It would be good if the Z-axis was recalibrated after a power outage. I'll explain the situation. I wanted to resume printing (since I wasn't home), so I plugged the printer (MK4) into the socket and set it to continue printing. Meanwhile, I was doing something near the printer and accidentally bumped into the bed, causing it to shift, and the printer started printing slightly off. So, I unplugged it again and then plugged it back in, and the printer raised by about 3mm and moved very slowly to 0 0 0 and the opposite corner. Then it started printing but slightly higher than it should have. So, I tried turning it off and on again and manually moving the printer up in the meantime, to see if it would return to the original position when I hit "Pause" or "Remove filament." Fortunately, it did not. So, I wanted to suggest that it might be good for the printer to record its position before pausing or changing the filament (in my case before a "power outage") and then return to that position (Z) afterwards (and if a power outage occurred, it would also recalibrate the Z-axis).
