Automatic Shutdown Set-up with BTT Relay V1.2 with Octopus Pro V1.1

[zjudy]

I recently purchased a BTT Automatic Shutdown Relay V1.2 for my Voron 2.4 with an Octopus Pro V1.1.
The relay didn't come with any specific instructions for how to install and configure the relay with klipper.

I understand the physical wiring part, where I'm fallings short is the steps needed inside of the Octopus Pro firmware and inside of klipper to make the relay function.

If anyone has any kind of supporting documentation would be much appreciated if it could be shared on how to set up the relay.

Thanks!

I also have the same board running on P3STEEL running on a BTT Manta-M5P, to do the Hardware installation I use the attached Wiring Diagram picture from the biqu.equipment website.

Software Configuration, I wrote this small script, it gets the job done,  though it's not perfect by any means.

Simply call the macro from the END_PRINT to shut down the printer once the printout is completed.

1.- Add the following configuration to printer.cfg for the relay module:

###
     [output_pin shutdown_relay]
     pin: PA8  # Replace with the correct pin for your setup
     value: 0
     shutdown_value: 0
###

2.- Add the following macro to control the relay for automatic shutdown  to your macros.cfg:

###
     [gcode_macro M81]
     gcode:
       SET_PIN PIN=shutdown_relay VALUE=1
       M117 Shutting down...
###

3.- You can also add a macro for manually turning the relay ON and OFF:

###
     [gcode_macro RELAY_ON]
     gcode:
       SET_PIN PIN=shutdown_relay VALUE=1
       M117 Relay ON

     [gcode_macro RELAY_OFF]
     gcode:
       SET_PIN PIN=shutdown_relay VALUE=0
       M117 Relay OFF

###

I hope this is a good start for you to configure the module.
