Cheap IR sensors do not make good endstops






I had such high hopes.

These IR sensors are really cheap, and I was thinking of using them as a cheap auto bed leveling sensor or just as a contactless Z endstop. As you can see from the photo, I even printed mounts for them. One is mounted on a fan cover and would have gone on the Titan Aero's heat sink fan. The other is supposed to mount on the FLSun Cube as a contactless Z endstop.

Then I found out why no one is using these sensors. They are just inconsistent, easily affected by ambient light, and even minor differences in surfaces. So repeatability will be a super problem.

Oh well... at least the mount for the FLSun Cube can fit a mechanical switch too.
