Hello Romain

I have flashed the file i believe everything works good except hotend fan
is it fine if i connect my hotend fan at HE1
on marlin file its at E0 till E5 but no success and it triggers at 50 degree

I didn't understand the meaning of your question.
What do you call "hotend fan" ? 50mm radial who blows the print or the 30mm fan who blows the body of the hotend ?
30mm fan should be connected to permanent 24V
50mm radial fan should be connected to "CNC fan plug"

damn it whas my cooling fans not the connection Romain
i got confused becouse yesterday i burned my radial fan
