Marlin _V6 Cooling fan Control

Following  upgrade to V6 Hotend, the filament jambs at the entry; the cooling fans are not running.

Control board is Melzie, running Marlin.

What is the code to control the fans, and into which configuration file should it be placed?


Answer this question I have this problem too

Is this a good question?

Hi Les,

You would have to check your firmware to make sure the pins that the cooling fan are connected to are configured correctly (also make sure you have the polarity correct), alternatively you can wire the heat sink cooling fan directly to the power supply to endure it is always set to on.
