second cooling fan
second cooling fan
I'm not in front of my printer (RMaxV2) at the moment but is there an extra place on the Rambo board for a second cooling fan? Not the hotend fan but the PLA fan.
Re: second cooling fan
I'm not sure about the newer Rambo boards, but my Rambo v1.0 has two extruder fan outputs next to the extruder heat outputs. They are labelled EXT0 FAN and EXT1 FAN.
These are pwm outputs that can control the PLA cooling fans with variable speed, and should be able to be controlled by gcode based on your firmware.

Why not connect them to the same pins?
Unless ofcourse you want to control them separately.
