+In pronteface.py: To get the values from the firmware, type \\
+<code>M501</code>
+Ex:

+</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,…)
