Rotary and linear optical encoders are common ... to interrupt a light beam. All rotary encoders consist of a light source, light detector, code wheel, and signal processor. There are two basic ...

He got his hands on some motors to drive the build platform but it doesn’t have a built-in encoder. He knows that optical encoder wheels can have ... suits your needs a bit better.

I removed the mechanical scroll wheel rotary ... cheap mouse encoders are known to cause a lot of contact bounce so you will need to debounce the signal from the encoders. I have tried some variants ...

In the video after the break [365 Robots] takes us through the build process of a closed-loop motor with a custom optical encoder ... roughly 2% of a typical NEMA17 stepper motor.
