Is this behavior normal?

peirof

Hi,

As I saw that I did not know how to configure the control of the temperature of the bed and the Hotend at the same time, what I have done has been commenting on the lines corresponding to the Hotend, and I am calibrating the temperature of the bed

The question I have is if what it is doing is normal, since it reaches the temperature indicated for the calibration 70º, begins to drop to approximately 65º, and rises again, this cycle has done it 5 times or more ( i have not counted)....

Writing this, has changed Phase 4.... but bed, dont have fan....

8/17/2021 08:16:06 Auto tune starting phase 4, tuning with fan off
8/17/2021 08:05:17 Auto tune starting phase 3, heating system settling
8/17/2021 08:03:12 Auto tune starting phase 1, heater on

@peirof thats normal. just let it run. It may take 15 mins or it may take an hour or more.
Wait it out and then add the output from M307 to your config.g or use M500 to save the results to your config-override.g file

now, at the end, i am tunning temperature of Hotend....

I can remember, but its normal, in calibration, when hotend reaches temperature configured in fans, 70 º, dont power on?

@peirof are you tuning the hotend using H1 or T0?
only T0 uses the fans

@jay_s_uk said in Is this behavior normal?:

T0

With this M303 H1 S210

@peirof use M303 T0 S210, then the fans will activate during the tuning cycle
