Hi Guys,
I have a Zonestar ZRIBV6 board and I'm not sure what happened, but now my cooling fan is always on. What I did is switch the FAN1_PIN and FAN_PIN pins in pins_ZRIBV6 and it worked perfectly.
I am now trying to upgrade the firmware. Everything is working, except that now the cooling fan part is always on too. If I switch the pins back in the pins file, they work as expected with the hotend fan now turned off. Switching the pins causes both fans to be turned on directly after power up.
Here's my configuration in _adv file, which I never touched and is the exact same as the original fw.
#define E0_AUTO_FAN_PIN FAN1_PIN
#define E1_AUTO_FAN_PIN FAN1_PIN
#define E2_AUTO_FAN_PIN FAN1_PIN
#define E3_AUTO_FAN_PIN FAN1_PIN
#define E4_AUTO_FAN_PIN FAN1_PIN
#define EXTRUDER_AUTO_FAN_TEMPERATURE 50
#define EXTRUDER_AUTO_FAN_SPEED 255 // == full speed
The pin definitions are:
#define FAN_PIN 9
#define FAN1_PIN 6
All I am doing is switching 9 and 6. I am confused as to why it would work in the original fw and not the new one. Is there anywhere else you define fan pins?
Thanks
