@droftarts Thank you! I will order one. I am guessing low signal means tied to ground. Which part of the gcode command defines the endstop that it is connected to?

Re: Filament Runout switch on Duet 0.6

I have read through what I believe to be the new filament runout details: https://docs.duet3d.com/User_manual/Connecting_hardware/Sensors_filament , but was unable to work out how to connect one to my Reprap Fisher Delta with a Duet 0.6. It is running firmware 1.26. How can I add a Fimament runout sensor (gcode to add and pins to connect to.) Also, what sensor should I buy? I just want it to pause print if no filament.
