Introduction

A spare endstop can be used to trigger a full system reset. we will be using the arduino to convert the flow sensor signal into an on or off state. flow or no flow.

Tools

No tools specified.

  1. Upload this code to youre arduino nano.  Refer to the diagram on how everything is connected. The hardest part is crimping the pins for the endstop connector. If you are using either the Duet 2 Maestro or hardware version 1.04 of the Duet 2 WiFi/Ethernet, these boards can tolerate 5V on the endstop inputs. Or you can add 4 diodes in series to drop the voltage to 3 ish volts.

    • here is a simple case i made for the nano.

    • Now we have to tell the duet what to do with the on/off signal using the M581 command. insert this into your config file.

    • M581 E1 S1 T0 C0

    • this explains what we are doing here.

    • And thats it!!! you can test by unpluging your pump or pinching a line, it should reset within a few seconds.

Finish Line
