#Issue in RatOS.cfg when using PD15 and PA8 for custom fans

VCore 4.0 IDEX. Upgrading to RatOS 2.1
I have added a back and side aux cooling fan and am having issues with the RatOS.cfg [board_pins btt-octopus-11] aliases. I would like to use PD15 which is aliased to chamber_filter_4p_fan_enable_pin (used to supply 24V to the filter fan which I have powered by splitting FAN6). When I attempt to use PD15, I get "pin PD15 used multiple times in config". If I add a custom [board-pins] alias as shown in the attached screen capture, I get "Alias chamber_filter_4p_fan_enable_pin mapped to PD15 - can't alias to PB10".

I realize I could change RatOS.cfg but it will get overwritten every update or configurator run.

How do I use these unused pins that have unnecessary/unused aliases? I also tried to alias them to "null' which produces an error.

Thanks!

If you dont select a chamber filter do those pins still get defined in ratos.cfg?

hm

#

you can always copy the ratos.cfg to another file, and in your printer.cfg comment out the include of ratos.cfg, and include your file instead. Then you can edit your custom ratos.cfg without it being overwritten every reboot.

#

I feel like there should be a way to make ratos.cfg not fight you on this, but I don't know how the configurator works well enough

nope, ratos.cfg does additional includes itself

This aliases entry prevents using PA8
fan_part_cooling_pin=PA8,
The part cooling fans are driven by the toolboards. Do you see any issues deleting that alias as well?

cinder raptor
#

are you not using the toolboards?

There are three "fan_toolhead_cooling_pin" aliases in RatOS.cfg in board_pins for btt-octopus-11, toolboard_t0 and toolboard_t1. Given I have an IDEX machine, the one in btt-octopus-11 is invalid.
