Are you saying that it is not getting hot at all? Are you getting any messages on the screen? Can you post a screenshot of Device Monitor showing you firing the device?

@inteks.... in your example...  " i made a profile with temp at 230° and 10w and 75w preheat for 5sec. and it stays cold.  what is wrong?"

What do you get when you keep the same settings except increase the wattage from 10 watts to say 30 or 40 watts?

Ok, I just set my DNA75 up like you had with the preheat & at 230°c,10w power, 75w preheat, my device was dropping out of TC & into power mode because at 10w power, the board is not seeing enough temperature rise...when I raised the power setting to 50w, it worked fine.

ok.
here are 3 screens with 10w 30w and 75w...

at 30w it looks like a "little" preheat. but its far away from configured 5sec. ! 

and it doenst reach the configured 230°C before it falls down...

Try taking your temp way higher, it's by no means accurate when used this way

Did you try it, the numbers mean nothing as far as what the temp really is.
275 -280 C should do it.

From the 3 screenshots the preheat is working.  You can see that the wattage settings 10 watts doesn't get you to the set temp of 230, the 30 watts almost gets you to the set temp of 230 and thew wattage setting of 75 easily gets you to the set temp.  Preheat, as you know is the green lines on the graph....

As @giz_60 said earlier.... "because at 10w power, the board is not seeing enough temperature rise".....

yes on 2. screen it looks like preheat is working. but why does it stop after a second if it doesnt reach the configured temp?

the wattage falls down at 200°C instead of 230°C ?!?!

Looks like the battery sag is kicking off the preheat & when the voltage rises, its firing at the set wattage...
