I have an Airwolf3DHD for which I intend to modify the extruder head assembly and install an additional fan for part cooling as I plan to print PLA on the printer.
I’m unsure as to how to go about doing this. The printer has a RAMBo 32-bit board that runs on Marlin firmware. I have been able to obtain the original version of the configuration.h file for the printer from the manufacturer. Ideally I prefer the print cooling fan to be controlled by the 3D printing software.
Any help in this direction will be greatly appreciated. Thank you!
