Hİ i have 24v 14.5 amp power supply. I set 110 degree but the temperature is rising very very slowly (45 mins) . I double check my 24v system tried 4 different heated bed. Replace cable, isolation heated bed etc…

Is that about my config file . Pwm or another settings for heated bed. Have you seen this problem before?

Regards.

Your config file looks ok.

  • Are you sure you have the right thermistor type ?
  • What is the exact model of your heated bed ?
  • Are you using a Smoothieboard ?

1- i am using ntc100k.
2. i think it’s about my mk2b heated bed.
3. yes of course i am using smoothie board 5c.

thanks.

NTC100K has a beta of 4400. Your thermistor is set to EPCOS100K which has a beta of 4066, so you are not getting correct temperature readings.

Comment the thermistor setting, uncomment the beta setting, and set it to 4400.

Cheers.
