3D printer fan(s)
Posted: July 11th, 2019, 6:27 am
Hi,
I am trying to understand the configuration of the fan(s) used in 3D printers. As I understand there can be 2 fans :
1. External cooling fan that is pointed towards the part that we are printing.
2. Extruder fan that helps cool the extruder drive mechanism,
Ramps 1.4 has D9 connector for a fan connection and M106 command turns ON this connector. Where do I have to connect the second fan ? Which gcode command deals with it ?
