Current setup: RAMPS 1.4, Firmware 1.1.8, Full Graphics Display
Adding hard ware RRD Fan Extender
This extender works by using the 12V pins for power supply and plugging into the servo connector on the RAMPS board.
Pins 1 &2 are the 12V input from the RAMPS board.
Pins 3 & 4 12V fan connection
Pins 5 & 6 12V fan connection
I believe I can use FAN1_PIN and FAN2_PIN for this.
In the "pins_RAMPS.h' file I added the following to:
#if ENABLED(IS_REAMPS_EF
#define FAN_PIN RAMPS_D9_pIN
#define HEATER_BED_PIN REAMPS_D8_PIN
// I added:
#define FAN1_PIN 6
#define FAN2_PIN 11
Then I used M106 P1 128
M106 P2 128
to turn on the fans.
This setup only works for #define FAN1_PIN.
FAN2_PIN dose not work with M106P2 S128 or M42 P11 S128
So I'm guessing that for some reason I don't know about I can't use #define FAN2_PIN definition? Or what should the M106 or M42 command look like?
Any help would be appreciated.
Thank you
