Fan2 for light

Morris

I have an effector light connected to fan2 on radds When I press light on radds display it goes on for a second then goes off. When I start the printer it also goes on for a second then goes off. Why doesn't stay on?

Repetier

Typical reason would be having some other function using the pin as well. If you have for example configured 2 fans it would turn off the fan2 on next pwm set since the fan is off by default. Same if that pin is set as cooler fan for an extruder or something else. So check config what else apart from light toggle is using the pin.

I don't see where I have used the same pin twice . Attached is a picture of my pins.h and two instances where fan is mentioned in config.h. Is there somewhere else to look ? Is this damaging to the DUE?

config:

#undef FAN_BOARD_PIN
#define FAN_BOARD_PIN -1
#define BOARD_FAN_SPEED 255
#define FAN_THERMO_PIN -1
#define FAN_THERMO_MIN_PWM 128

#define FAN_THERMO_MIN_TEMP 45
#define FAN_THERMO_MAX_TEMP 60
#define FAN_THERMO_THERMISTOR_PIN -1

Here are the pictures --dont know why they dont show up

Light gets set over

CASE_LIGHTS_PIN whcih I do not see in your config part.#define FEATURE_FAN2_CONTROL 1
mean enable second fan and that also uses FAN2_PIN and will disable a light enabled with M355.In that caseM106 P1 S255 should enable the light.

Morris

here it is. but M106 P1 S255 doesnt enable the light.

Morris

so i should make fan2control 0? please let me know

Repetier

Yes
#define FEATURE_FAN2_CONTROL 0

should be set so it does not use same pin. Also check if you have no cooler pins set to fan 2.

Morris

Can this be changed in the EEPROM or does the firmware have to be reloaded

Repetier

No you need to upload firmware for that. It changes the software code.

Morris

If I want to change the firmware without changing eeprom settings and I don't know if it was on 1 or 2 the last time I uploaded, is there a way to find out or do I use 0?

Repetier

0 is disable eeprom usage. No firmware does not report the content of that byte, sorry. All you could do is make a copy with host/server of your eeprom settings.
