If you have installed a heated bed on your printer and you think that the control board needs cooling, use this thing.
"It works perfectly for cooling your new TMC2100"
- now is available to install the "Aero Tunnel" for cooling your stepper driver without interfering with the heating of your heated bed.
- The update consists of an add-on, it does not involve any change to the previously installed PCB support.
I used this fan configuration for my Controller Board:
Extruder cooler: FAN1 connector
PCB cooler: FAN2 connector
Setting up two simple changes this firmware https://drive.google.com/open?id=0B8VIB533cgdMdVl2Z2tHWkJHbTA in "Configuration_Adv.h"
1: #define E0_AUTO_FAN_PIN -1 -----> edit to #define value E0_AUTO_FAN_PIN 7
2: #define CONTROLLERFAN_PIN -1 -----> edit to #define CONTROLLERFAN_PIN 44
For peace of our ears, the PCB cooling fan will be started only when printing, but will be turned off to finish printing. ;-)
You can reverse the pin 7 to pin 44 at your convenience, it depends of the connector you used for your fans
- tunnel with increased height and length for TMC2100 + Protector Filter or with Big heat sink for higher cooling performance
