BIQ Opto Endstop
RepRap compatible Opto Endstop using an Opto End stop with a 0.5mm beam slightly smaller than the HB102 beam with of 0.8mm. The opening of the interrupter is 5mm allowing for a 3mm black perspex interrupter tag designed for use on Huxley Seedling but can be used on All RepRaps.
Project goal was to Design:
A small low cost PCB < £1.00 for 3 bare PCBS.
Low cost of components.
With a smaller beam to break.
Wider opening for a 3mm interupter and little more clearance.
Three circuit build configurations. ECO, standard, and Iluminated.
Reprap Standard mounting centers. (holes)
==ECO (easy to build Discreet components)
== Standard == (more dificult to build Discreet components with one Surface mount resistor)
== Iluminated == (dificult to build Discreet components with two Surface mount resistors)
To be updated with files and build pictures.
