Door sensor calibration failure

I'm having problems getting my door sensor calibrated correctly following the on-screen instructions. It keeps on telling me to tighten the door sensor screw to the point where I can't tighten it any more. This is after the step where I have to put my hands in between the doors. The procedure seems to be different from the documentation. The printer does detect my door properly. It'll stop the print mid-print when I open the door. Am I doing something wrong?

RE: Door sensor calibration failure

The door tensioning screw shouldn't be fully tightened. Loosen it off until the metal rotary section of the door sensor just poke through the hole. 

Open and close the door yourself and adjust so that you hear the sensor click around an inch or so before the door actually seals closed. Once you have it at the location begin the door calibration wizard with the door closed. It will ask you to fully open the door......then close the door with your fingers in between. If it asks to you turn the tensioning screw at this point, do it, but then close the door again with the fingers in the way each time - not fully closed. It should then pop up and inform you it is successfully calibrated. 

Mine kept failing as well initially, but it was my error as I went reading it properly and not placing my fingers in between the door! lol

RE: Door sensor calibration failure

I figured it out. I had to back out the screw and the door sensor to the point where it didn’t click. Then I did the calibration procedure. It first asked me to tightened until the door sensor clicked. Then it went to the hand procedure. With a hand in between, the door sensor is NOT supposed to click. The whole calibration procedure is meant to get the door sensor to trigger as early as possible. I had the sensor adjusted too far forward during the initial install so the door sensor clicked even with a hand gap. Of course, the tutorial didn’t know that since it assumes the sensor is protruding minimally, so it kept on asking me to tighten.

I recommend during assembly to start with the sensor NOT clicking to allow the calibration process to do its job. Similar to the Nextruder gear calibration.

RE: Door sensor calibration failure

Thanks for summarizing! It failed 2x for me, but then went through and I had no idea what I did "right".
Now I know.

This is what I had to do as well.
