Hi
Please can you tell me where do I can connect the Fan that cools your prints as you print on the Ramps 1.4. If i connect to the power supply, then the fan runs at 100% all the time. Where do you connect where the software controls the fan.
You can connect your fan on the D9 connectors. And you must configure your "configuration.h" file properly, then you can use the fan with M106 command.
