Suicide Switch

Disclaimer: I am not responsible for anything you do.

The problem:

Many a time I have needed to run a print well into the night, leaving me with two options. Leave the printer running all night or wake up at some ungodly hour to turn it off.

The solution:

Enable to printer to pull the plug on itself at the end of the print, in a reliable, simple to implement solution.


My printer started life as a Da Vinci 1.0, however it's now running an mks gen 1.4 board which has servo outputs. Your printer may differ.

For this, you will need:

A control board that has a servo output.

1 x R/C Relay such as https://littlebirdelectronics.com.au/products/pololu-rc-switch-with-relay-assembled

1 x r/c servo extension cable

1 x regular relay such as https://littlebirdelectronics.com.au/products/30a-horn-relay-spst

1 x momentary push button of your choice (hence forth known as the ignition button)

Please refer to the diagram how to wire this, if it doesn't make sense t
