PINDA probe LED flickers then goes off with ABS
When i turn the printer on, the red LED is on, but when I preheat for ABS or start an ABS print, the probe will start to flash after a few minutes. It does this even before the printer has reached its target temperature. After a short time later, the probe will turn off completely. When I try to start a new print before it cools down fully first, an error measage will appear saying 'Bed leveling failed. Sensor disconnected or cable broken. Waiting for reset'.
I have disconected and reconected the probe, wiggled the wires to try to get the LED to turn off, but it works fully while the printer is cool. I suspected the PSU becasue it only seems to happen when it gets hot under load, but the voltages are completly stable during any load.
I would really love some help please, it has to be the PINDA probe, RAMBo or PSU but i have no idea which?

Raise Z to 100mm.
Heat the bed to 100 degrees and go to the "Show End Stops" menu option
Put something metal (coin) under the probe; you should see both the probe light and LDC switch states for "Z".
Then do the same close to the bed, near the point where calibration fails (usually the right side).
