Raspberry ON/OFF heater control error (Scheduled digital out event will exceed max_duration) #5561

Closed cinadr closed 2 years ago

cinadr commented 2 years ago

Hi! I have a 220V infrared heater in my cabinet. It is connected through a relay on my raspberry PI 4B gpio20 port. It is basically only an on/off heater. I have configured klipper to recognize it as a generic heater and klipper starts with the config without error. When I try to PID calibrate or turn it on, klipper shuts down with a message: "MCU 'host' shutdown: Scheduled digital out event will exceed max_duration". I've found this message in klipper source where I can only understand that some timing error is the probable cause. The GPIO list is the following:

gpiochip0 - 58 lines:

I upload the log here: klippy.log

I configured my DHT temperature source described here. I made two separate temperature files one for the fan and one for the heater (content is the same to share the sensor) but the error is still the same if I comment out the fan section and only the heater is activated.
