Is anyone using hysteresis with their chamber in Marlin?
I have read bang-bang with hysteresis is possible when using a bed heater. I would like to do that for chamber heating. I have some lamps that can't keep flicking on and off so rapidly around a setpoint - this causes the bulb to die out faster and the noise is annoying.
Steps to Reproduce:
- Start with fresh Marlin Firmware bugfix 2.0
- Enable chamber temperature in Configuration.h (
- Set chamber hysteresis value to 2 in Confgiuration_adv.h (
#define TEMP_CHAMBER_HYSTERESIS 2). Enable
#define CHAMBER_LIMIT_SWITCHINGin Configuration_adv.h. Decide on pin to use for your heater, if necessary
Expected behavior: I would like, when I set my chamber to 30 °C, the chamber lamps to come on until 32 °C, and to stay off until 28 °C.
Actual behavior: chamber heater lamps flick on and off at 30 °C (29.9 - on, 30.1 - off).
