How does a 4pin TTL sensor PCB get implemented in the context of the typical 3pin RAMPS endstop inputs? eg: I suspect this is a stupid question, but everything I google is avalanched by products and a distinct absence of useful information.by BETLOG - General
I noticed my partfan is always on. No, it's not that I don;t understand gcode or how my slicer works M106 is ignored. Although thats the odd thing, I got it to turn on and off using the button in octoprint a few times. The stock one didn't do this, it only relates to a new, slightly larger fans I substituted into a new cowling a few days ago. I did need to use a dupont connector in an XH socketby BETLOG - General
Quoteleadinglights It is just a comparator with neither gain nor filtering but it works as long as there is not too much electrical or mechanical noise. Thanks, thats what I was asking. So then it appears there are a number of alternatives available, with varying degrees of suitability and cost.

Is it just me, or are the diagrams so small as to be illegible? V1.1_piezo_signal_conditioning_board.png I'm very interested in using piezos - I have no doubt that this is the immediate future of cheap endstops - and am trying to figure out if I can/should make a board, or buy a precision peizo (which after shipping seems *rather* expensive), or does a cheaper chinese version exist?
