There comes no signal out on the ring-light-connector....
Not on pressing light on and not on calibrating or scanning...... :(

meanwhile i could measure the pin (data out on the chip), there are permanent 0,14V (no matter if the ring-light is turned on or not).
I also put the latest fabscan-image on another sd-card to try it with the original-image, but also no success.

Does the motor turn or Laser switiching work (just to be sure that the serial connection to the HAT works)? Have you checked the solder joints of the led ring connector? There should be a voltage of 5v on one of the ring connector pins. Check if the polarity of the connector is reversed (soldering)?
