Fan speed at 200 in UltiController

[drayson 75]

Hi,

recently I updated my firmware via Cura 13.06.4 (standard which is included with this cura version).

Now I recognized that the fan speed displayed at the Ulticontroller shows a value of 200 while printing.

Has anybody else the same issue?

Suggestions? Any hint appreciated...

what's your fan Min and Max in Cura? (Expert Settings)

Hi,

min = 80%

max = 100%

Do you think that´s the root cause?

That's all OK Drayson.

The 80% is what's giving you the speed of 200.

If you need 255 all the time you would need to set Min and Max at 100%.

If you look through your G Code you will notice a bunch of lines that start with M106 and finish with S(200 to 255).

Unless you need to have your fan running flat out all the time you could leave it as is.

For ABS I have Min and Max set to 30% with dual fans. Which gives a fan speed of 76.

Thank you owen, explaination understood. 100% is equal to 255 (guess rpm)

Just some kind of calculation as usually... :-)

No, not rpm. 255 is simply the biggest number which can be stored it one byte. ;-)

Ahhh.... ok, seems that I had a nap during my IT lessons... :-)
