Thank you very much for your support! I previously came to the idea that Chiron is not working well with some detail settings of Cura, like the variable layer thickness. Maybe is the case now. My previous setting was to start with the regular fan speed 0.

It's working after all. The previous test I made it printing on-line with the printer. Now I generated the G-Code and I print from the SD card and is working fine.

I Have it the same.

Is good to know that you made it and was right. Now let's see what is wrong with mine! First I suspected the hot-end wiring which failed first, but I have replace it. Now I started printing an old calibration file that I have it on the SD card and the cooling fan worked. AC_3cm paralelipiped.3mf

I have just M107 for Start G-code. M106 S0 I have just at the End G-code.

Why my Chiron cooling fan doesn't start anymore with the last updates of Cura? I tested with an old G-Code and the fan is working but now the G-Code generated is not starting my extruder cooling fan.
