This will heat your hotend up. Stay near your printer in case of problems.

Be sure your hotend is not near your bed, or touching anything.

Run this command:

M303 H1 S250

Your hotend will go through a PID tuning cycle. When it's done, run M307 H1 to see the values, it will report something like this:

Heater 0 model: gain 199.0, time constant 962.6, dead time 4.5, max PWM 1.00, calibration voltage 24.2

Using that as an example, find the M307 H1 line in your config.g and adjust it as follows, using the values for gain, time constant, dead time, and voltage from your M307 output

M307 H1 A199.0 C962.6 D4.5 V24.2 B0
