Solved Can you use PD15 (on J55 FAN5) as 5v GPIO?

Hi Everyone,

I'm near the end of my 2.4 build and there are only a few things left that I'm trying to finish on it. I wanted to put a the BTT Relay v1.2 on the bed as well as the SSR. I can get the PS_ON pin to work with the BTT Octopus Pro board, but struggling to get a pin to control the reset. It should be able to be activated with 3.3v - 5v from what I can find in the documentation in english.

I currently have wired PD15 (from J55 FAN5) to the reset pin. I have the voltage selector for this fan port to 5v. I've used the following config:

[output_pin PS_ON_OFF]
pin: PS_ON; Alias for PE11
value: 1

[output_pin PS_RESET]
pin: FAN5 ; Alias for PD15
value: 0
shutdown_value: 0

[delayed_gcode ps_reset_release]
gcode:
SET_PIN PIN=PS_RESET VALUE=0

[gcode_macro BED_POWER_ON]
gcode:
SET_PIN PIN=PS_ON_OFF VALUE=1
SET_PIN PIN=PS_RESET VALUE=1
UPDATE_DELAYED_GCODE ID=ps_reset_release DURATION=5

[gcode_macro BED_POWER_OFF]
gcode:
SET_PIN PIN=PS_ON_OFF VALUE=0
SET_PIN PIN=PS_RESET VALUE=0

[gcode_macro BED_POWER_TOGGLE]
gcode:
{% if printer['output_pin PS_ON_OFF'].value > 0 %}
BED_POWER_ON
{% else %}
BED_POWER_OFF
{% endif %}

Even manually setting PS_RESET does not reset the relay. The power on the relay does start on until I turn off PS_ON_OFF though, so the relay is switching. Just not resetting. Has anyone got any ideas how I could do this? Happy to try and wire it differently if that helps, went with this as it seemed most feasible. I was going to default PS_ON to 0 once I can get the reset to work.

In case anyone looks at this in the future and has the same problem. I switched to using PG15 (from J34 - STOP7) and the script works perfectly. I have it so the power to the bed ssr is deactivated before and after a print or with an emergency stop. It turns on in at the start of print_start and switches off in print_end.
