Much appreciated. Peter

The extruder fan on my SD3 is always on and further more remains on when the printer is switched off.
Had to replace cooling fan after a couple of months.

How does it run without power to printer - Unless you mean when you remove the printers external power but you are leaving it connected to the PC - which means its still USB powered and its not just the fan thats powered then either... Its the entire printrboard..

You don't - its supposed to be on 100% power 100% of the time.. its not a Print Fan (which is what people are referring to when they speak of PWM controlled fans....)
