BIQ Opto Endstop
RepRap compatible Opto Endstop using an Opto End stop with a 0.5mm beam slightly smaller than the HB102 beam wdith 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.
The output of all three versions is an Open collector active High signal.
Active high means a 1 is made when the end-stop is triggered.
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 interrupter and little more clearance.
Three circuit build configurations. ECO, standard, and Illuminated.
Reprap Standard mounting centres. (holes)
Master Schematic of board
Master CCT of the PCB.
(easy to build Discreet components)
(more difficult to build Discreet components with one Surface mount resistor)
(difficult to build Discreet components with two Surface mount resistors)
