Turn OUT1 to always on?
-
Hello all!
Duet 3 Mini5+ and Toolboard.
I'm wanting to plug the power to the toolboard into out1 and have it always powered on. Is there a code I can add in the config file or should I be doing it a different way?Thanks!

M950 P0 C"out1" ; Create a GPIO pin to provide power to the toolboard M42 P0 S1 ; Turn that GPIO pin on at boot
That worked perfectly! Thank you so much!

@nightlonk42 we do not advise powering a tool board from an OUT port, because of the common-mode CAN voltage that would be applied when the tool board is powered off (which could disrupt CAN communication) and because of the current surge that will be drawn when you power up the tool board.
The recommended approach is to power the tool board from the same PSU (typically 24V) that powers the Duet, through an inline 5A fuse if you are not using a tool distribution board. Here's an example of an inline fuse holder: https://www.ebay.co.uk/itm/262131520883.

Makes sense. I will do that instead. Thanks!
