More than that, the optical encoder could also detect whether or not the filament was actually moving through the extruder.

Quadrature optical encoders provide feedback signals in the form of A, B, and Z pulses. Therefore, the A and B signals (exhibiting a phase separation of 90° from the encoder's code wheel) are in ...

C&K has launched an optical rotary encoder, the ENC Series 24-Position Optical Encoder with integrated pushbutton.

The PK Series two-phase stepping motors with an optical encoder are now available as standard (1.8°/step) or high (0.9°/step) resolution models. The PK264 (1.54" stack length) and the PK266 (2. ...
