Axon builds the BFB file using Gcodes. The file is readable with any text viewing program.
Some basic Gcode knowledge is required in order to identify which extruder is used for a
particular purpose i.e. raft, model or support material. It is also a requirement to identify
which material the Gcode extruders are running by observing the temperatures in use. E.g.
if the Gcode file contains M104 S260 and M204 S195, this indicates the Gcode file expects
extruder 1 to contain ABS and extruder 2 to contain PLA. If your physical printer is indeed
loaded like this, you cannot simply remap (swap) the extruders due to the material
difference. This would cause the printer incorrectly operate extruder 1 at 195C when it is
physically loaded with ABS (requiring 230 - 260C).
What follows is the simplest usage scenario. Your machine is loaded with different
coloured PLA in extruders 1 and 2. You have a Gcode file that only uses extruder 1 PLA.
You can remap Gcode extruder 1 onto physical extruder 2. This will result in the print solely
using physical extruder 2. (Physical extruder 1 will be unused.)
Remapping extruders is achieved by going to Settings -> Extruder Mapping. Identify what
each extruder is used for in the Gcode, determine which physical extruder you want them
to map to. Pressing X+/- will change Gcode extruder 1 mapping. Pressing Y+/- moves the
menu cursor between Gcode extruder 1&2. It is not possible to select Gcode extruder 3 as
this is automatically set to the remaining physical extruder.
There are a few things to note:
 When extruder remapping is enabled, the user is prompted about this prior to
selecting a print file because the remapping can result in unexpected behaviour if the
user is unaware of the active remapping function.
 The remapping configuration settings are not stored persistently as this is deemed
undesirable. When the printer power is turned on the remapping reverts to 1:1
direct mapping. (The aforementioned pre-print remapping prompt is not shown
when the mapping is 1:1)
 Please ensure the Gcode file allows enough room between the left of the print and
the printer framework. I.e. attempting to print the test raft Gcode file with a double
extruder RapMan will cause the extruder carriage to hit the framework when it
attempts to position physical extruder 2 into the far left corners of the print bed as
the raft Gcode file instructs.
