Part cooling fan and hot end fan questions
Finally after 2 years I got my vcore 3
1 500 machine running. However it leads to two more questions.... the hot end fan...should it be pushing air towards the heat sink or should the air be pushing away?
Also the part cooling fan runs faster at a lower percentage speed command. Example 100% the fan is off, 20% seems to run fastest? Is there a way to reverse that? Thanks guys!

To fix the fan you need to add a
! like this
The hotend cooling fan should blow through the hotend, towards the X railHey guys I'm bringing this back up because Im sure Im doing something wrong. I found my part cooling fan being controlled by PA8. It has an explanation point in front of it. When i delete the exclamation point the fan acts correctly. To re-cap when the part cooling fan on the mainsail screen shows zero its actually running 100 percent. Unfortunately I think where Im changing this is the problem..... anytime i restart the machine it reverts back to having an exclamation point in front of PA8 and the fan working wrong.
I did fix the hot end fan. Was definitely pushing air in the wrong direction. Thanks Chris
Only make changes to your printer.cfg file. All the other files are regenerated
so the funny thing is I cant find the "part cooling fan" in the printer.cfg file
The only place i find this command is in RATOS.config line 355
Solution
Copy it over to printer.cfg and then change it to what you want

RatOS uses a modular configuration that heavily takes advantage of the config file include and merge logic in Klipper. For this reason, the order of includes and overrides are very important, do not change the order of the configuration unless you know what you're doing.
