More than two extruder

Hello all.
I have finished (well, almost) building a triple extruder printer, but I am dubious about firmware support:

Config.h says that maximum 2 extruders are supported:

/** Number of extruders. Maximum 2 extruder. */
#define NUM_EXTRUDER 1


Extruder.cpp on the other hand says he's ready for more:

#if NUM_EXTRUDER>2
const char ext2_select_cmd[] PROGMEM = EXT2_SELECT_COMMANDS;
const char ext2_deselect_cmd[] PROGMEM = EXT2_DESELECT_COMMANDS;
#endif
#if NUM_EXTRUDER>3
const char ext3_select_cmd[] PROGMEM = EXT3_SELECT_COMMANDS;
const char ext3_deselect_cmd[] PROGMEM = EXT3_DESELECT_COMMANDS;
#endif
...
...

As I am not able to dig all the code to understand the extent of support for more-than-two... here comes the question:

Does Repetier FW FULLY SUPPORT more than two extruders ?

Best Regards

Yes, the code is written to support up to 6 extruder, also it will be difficult to find a board handling that much steppers.

I would suggest to use the development branch on github for this.

All you need to do is copy EXT1_ and rename them EXT2_ and set NUM_EXTRUDER 3

I am just happy with a Megatronics 2 or 3: handling three extruders as it is.

Thank you, Sir, for quick reply!
