IDEX Part Cooling Fan Issues
Hi All,
I have just finished my IDEX upgrade and I am running into issue with my Part Cooling. The error is: pin PA0 is an alias for fan_part_cooling_pin
I used this guide https://os.ratrig.com/docs/guides/4028 when I first built my VC4 XY & Hybrid but since upgrading to IDEX I run into this issue.
I've used user overrides as below in my printer.cfg
I am using the BTT Octopus MAX EZ board.
Print cooling fan with Enable Pin for 0% on Printer Startup
[fan]
pin: !toolboard_t0:fan_part_cooling_pin
cycle_time: 0.01
enable_pin: PF7 #(HE3) on MAX EZ board
Print cooling fan with Enable Pin for 0% on Printer Startup
[fan]
pin: !toolboard_t1:fan_part_cooling_pin
cycle_time: 0.01
enable_pin: PF9 #(HE2) on MAX EZ board
Could anyone assist please?
Connecting a 4028 fan | RatOS
4028 server fans are becoming a popular option for part cooling because of their light weight and great pressure and flow rates. In this guide we'll go over how to connect one and use it for part cooling. 4-pin fans usually aren't used in 3d printers, and many boards only provide 2-pin ports, but fear not! There's always a way.

What happens if you put what the error actually says.
Replace fan_part_cooling_pin with PA0?
So try
pin: PA0
Ive tried:
[fan]
pin: !toolboard_t0:PA0
[fan]
pin: !toolboard_t1:PA0
but from memory it complains that PA0 has already been used. My VC4 is at work so I can't test until Monday.
I will double check the fan pin type in the configurator to make sure it's a 2 pin PWM as upgrading to IDEX I wiped the motion config.

It should be somehting like this:
Thank you... I shall give this a go tomorrow when I am back in the office and let you know how it goes.
Thank you for your help, that seems to have worked. Shame this isn't in the IDEX commissioning guide. 👍
@michaelaswood There are a lot of ways to connect the 4028
