Minor issue, but wanted to track it down.

The BOM for the OptoEndStop shows a single "3 pin housing". Yet, the instructions depict soldering wires directly into the PCB.

The real question is why does the BOM suggest the "3 pin housing"? Wouldn't you also need a "3 pin header" to go along with the housing? There is also a photo of loose parts that possibly depicts a "header" and not a "housing"?

Trying to sort out my parts before assembly

Thanks.

The instructions were changed in response to my experiences [forums.reprap.org] and it may be there are remnants of the previous instructions and BOM.

I connected the wire via a 3 pin header and housing combo but there was an excessive amount of force needed to insert the headers.

Chances are you'll not be wanting to plug and unplug the wires at the endstop itself so its probably best to just solder them on.

However, I believe the 3 pin housing listed in the BOM is for the other end of the wire that connects to the stepper controller board. The 3 pin header it connects to is part of the BOM for the stepper board itself.

sorry guys! the opto endstop docs are lagging a bit.

the way it should work is this:

[opto]---->[housing]

where you solder wires directly to the opto board, but then attach a connector at the end. then the endstop becomes an object you can simply plug into a stepper board.

i'll get some photos and proper colors up on the wiki soon.
