Runout Anywhere Redu

thingiverse

I was looking for a method of having Octoprint sense filament runout. Stumbled across: https://www.thingiverse.com/thing:3665614 I found the sensing in rwmech's thing a bit unpredictable - there was too much space around the filament guide and not enough room for the switch in the open position. Using rwmech's recommended ESP8266 and a kw11-3z switch I found the relative placement of parts pretty consistent and hence this design. Follow rwmech's instructions but note that the sketch needs to be modified slightly: All the occurrences of http.begin( need to be revised to http.begin(client, (I'm using the 1.8.13 version if Arduino IDE)
