Switch Shorts on 1LC Toolboard

RogerPodacter

I have a strange issue. I run an IDEX printer, and on my 2nd print head i have a Y feeder to accept 2 filaments. I manage which filament is loaded with a simple 5V switch connected to IO0 on toolboard 21 (1LC).

This setup has been working for months. I took a 1 month break from printing and now when i go to use this print head the switch does not respond. When clicking the switch the toolboard reboots, so it seems the switch shorts the pin with each button press. Perhaps i changed something and dont remember, but to my knowledge everything should be in a working state.

Any advice how to troubleshoot this? also i have multiple spare switches to use and when i swap one in they all short the board, so unlikely to be faulty switch.

below are my settings:

config.g (line 205 is the switch in question)
config(1).g

dc42

@RogerPodacter please show how you have connected the switch to io0 on the tool board.

RogerPodacter

@dc42 see attached picture. Switch connects to IO0 below the extruder driver port. if i reverse the switch wiring, there is no response from clicking. no shorts, but not registering in Duet (object model, sensors, gpIn, sensor 0)

jay_s_uk

@RogerPodacter why do you have 3 wires connected? you should only have 2

RogerPodacter

@jay_s_uk i dont think that was intentional to use 3 wires. i must have set it up in the beginning and it worked ever since. i just need normally open so i'll have to remove one wire figure out which one.

jay_s_uk

@RogerPodacter normally closed is usually the preferred option. reduces noise etc

RogerPodacter

@jay_s_uk is there a way to diagnose if the IO0 port is damaged in some way?

jay_s_uk

@RogerPodacter i would redo your wiring and go from there

RogerPodacter

@jay_s_uk thanks, i removed the 3rd wire and checked each wire re-mapping them. the switch is now working normally. i have no idea what happened or how i've been running for months and why it changed. my endstops are all connected with the 3 wires interestingly.

all is good now. thanks all.
