Heating speed control method

[Dennis_kim]

The temperature rise of the heater is too slow
Even if set after tuning with M303, it increases very slowly.
When heated with an external power supply of 24V, it reaches 100 degrees in about 4 to 5 minutes, but when heated with Duet3, it takes about an hour.

How can I increase the heating rate?

@Dennis_kim It sounds like you may have the S parameter in the heater M307 command set to a number that is less than 1. The S parameter sets the maximum PWM to be used used with the heater on a scale of 0 to 1. See https://docs.duet3d.com/en/User_manual/Reference/Gcodes/M307

Please post your config.g and config-override.g (if used), and the response to M115. Please also explain how you have it connected to the Duet. What voltage is the PSU connected to the Duet?

Also, please use English in your post subject titles; it will help you get support quicker.

@Dennis_kim Have you already done a PID tuning?

The title should be in English so you can get help. At first I thought it was spam.
