Replaced the strain gauge with the light sensor found down on the left column of the printer.

wired to an skr mini E3 v3.0

I printed it on it's face, with some supports (if i remember correctly) out of petg.

The stick needs some metal glued on it's side to properly and accurately interrupt the signal of the sensor. Wrapping alluminum might work, but until a friend told me this, i already cut a little rectangle from a beer cap lying around my room.

The screws are all original, i mean from the printer somewere

Finally I start trusting this printer now.
