The title explains it. Printer is an i3 Mega S running a relatively generic configuration

What pin should your partcooling fan be? according to your config PH6?

gloomy orchid Dec 23, 2023, 10:06 PM

#

According to the pin, yeah

#

I've checked the pinouts on various configs and it is sorta messing with my brain

#

I know there were three TriGorilla versions used on the i3 Mega S back in the day and I know I got the v0.0.2

#

I am still looking for a picture of the pinouts for MY board in particular but I keep only finding the 0.0.1 and 0.0.0 versions

If you have found a schematic it can help too

#

Now the thing that confuses me is that in other configs I see pinouts that are a completely different format

#

#

This is the most common image I found

#

The thing confusing me to hell is the fact that by looking at other configs I see these pinouts

#

[stepper_x]
step_pin = ar54
dir_pin = !ar55
enable_pin = !ar38
step_distance = .0125
endstop_pin = ^!ar3
position_min = -5
position_endstop = -5
position_max = 210
homing_speed = 30
homing_retract_dist = 5
second_homing_speed = 10

#

Taking the stepper X as an example, AR54, AR55, AR38, etc.

Those configs should have a pin mapping somewhere too

#

Would it hurt my printer/board if I switched the pinouts between the fans?

#

Like as a lazy fix to just have the hotend fan (which is inaudible anyway) run at 100% all of the time

#

... or alternatively if I switched the connectors themselves between eachother because they are right next to eachother, the hotend and part cooling connectors

Either that or better would be inside the config. Most likely you just used the wrong pinouts 🤷‍♂️

#

[heater_fan extruder_fan]
pin: PH6

[fan]
pin: PL5
```would be my suggestion

#

At least if the board has a printing indicating which pin should be which fan

#

This is quite a headache

#

I'll try it in a minute since my printer is messing with some polycarbonate ABS blend right now. Do not ask where I got a formerly 110 dollars PC-ABS blend roll

Yehp just had to switch the pins. So the printer.cfg pinouts more or less just intercepts the signals given to the pins rather than being a hardstuck connection
