+===== Configuration =====
+==== Configuring the extruder motor ====
+In pronteface.py: To get the values from the firmware, type \\
+<code>M501</code>
+Ex:
+<code>
+>>> M501
+SENDING:M501
+echo:Stored settings retrieved
+echo:Steps per unit:
+echo:  M92 X80.00 Y80.00 Z4000.00 E765.00
+echo:Maximum feedrates (mm/s):
+echo:  M203 X500.00 Y500.00 Z3.00 E25.00
+echo:Maximum Acceleration (mm/s2):
+echo:  M201 X9000 Y9000 Z100 E10000
+echo:Acceleration: S=acceleration, T=retract acceleration
+echo:  M204 S3000.00 T3000.00
+echo:Advanced variables: S=Min feedrate (mm/s), T=Min travel feedrate (mm/s), B=minimum segment time (ms), X=maximum XY jerk (mm/s),  Z=maximum Z jerk (mm/s),  E=maximum E jerk (mm/s)
+echo:  M205 S0.00 T0.00 B20000 X20.00 Z0.40 E5.00
+echo:Home offset (mm):
+echo:  M206 X0.00 Y0.00 Z0.00
+echo:PID settings:
+echo:   M301 P22.20 I1.08 D114.00
+</code>
+Read the ligne that starts with ''M92'' and write down the value from ''E###''\\
+Then use a ruler to mark 10 cm of filament and launch an extrusion of 10cm of filemant using pronterface. Then measure the actual amount of filament extruded. \\
+(M92 E###) * ( 10cm / measured) = new value for M92
+Enter this new value like this: <code>M92 E###</code>
+And save by typing this:
+<code>M500</code>
+Repeat 2 or 3 times to get the number right.
+==== Configure Slic3r settings====
+  * filament diameter : measure it from the actual filament used (do multiple measures and average it)
+  * filament extrusion multiplier: to lower (<1) or raise (>1) the amount of filament extruded
+==== Printer settings ====
+Use these values to play with the layers' heights for parts of the model (perimeter, fill,…)
