Part cooling fan
I am using ramps 1.4 set to operate two extruders and I wish to incorporate a part cooling fan in repertier..
I have also bought the RRD fan extender. Would somebody be gentle enough to explain to me what needs to be changed in the firmware to be able to activate the fan via machine code in the program. There is a lot of instructions over the internet but in repertier its a bit scant. Hope it can be done.
Many thanks in advance.
