I own a printer that uses a
RAMPS clone with 4 power outputs labelled E0, E1, Fan and Bed. I see there are
other RAMPS clones with a similar design.
I'm trying to set up the Configuration.h correctly, and the first hurdle is the '#define MOTHERBOARD' statement.
The relevant options in boards.h are as follows:
BOARD_RAMPS_14_EFB // RAMPS 1.4 (Power outputs: Extruder, Fan, Bed)
BOARD_RAMPS_14_EEB // RAMPS 1.4 (Power outputs: Extruder0, Extruder1, Bed)
BOARD_RAMPS_14_EFF // RAMPS 1.4 (Power outputs: Extruder, Fan, Fan)
BOARD_RAMPS_14_EEF // RAMPS 1.4 (Power outputs: Extruder0, Extruder1, Fan)`
BOARD_RAMPS_14_SF // RAMPS 1.4 (Power outputs: Spindle, Controller Fan)`
These all seem to cater to the original RAMPS board with only 3 power outputs. Which should I use? The 'EEB' version seems best for dual extruders, but will I then lose control over the fan output?
