Strange problem with new firmware

[dreamworker 1]

Hello, I installed the new firmware with the new version of Cura and I have this strange problem:

during the print session, the fans speed is slow down by the machine, when I rise again the speed using the tune menu, after a little time the machine slow down again the velocity to 7%. What can I do?

New Update on the situation:

I proceed yet with the print session, and I notice that the machine slow down the fans speed with incremental percentage, infact now is slowing down to 11% instead 7%, and before pass from 8%, to 9% and to 10%

The fan speed increases gradually from off at the start to whatever speed you set in the Cura, by the height you specify. So check the settings in Cura's expert settings.

The gradual increase is done by setting a new fan speed on each layer. Consequently, if you change it in the tune menu, it will get reset on the next layer start.

But I set fan speed min 100% and fan speed max 100%, like usual.

mmh Then is this a CURA problem not a machine firmware issue? I must change the fan full of the height to 0 I suppose.

Excuse me for this misunderstanding

Yes, but you have a 5mm 'full speed height'. So it won't reach 100% until z=5. Above that height the fan should be full on. Below that height it will gradually increase from off, on the first layer, to full speed by whatever layer corresponds to 5mm high.

Nothing to do with the firmware, no. Unless you aren't seeing full speed on the upper layers. And even then, probably not.

When I created the gcode, I forgot to change the value of "the fan full of the height" to 0.5mm, I look at the setting only after your reply... pardon :(
