+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 <code>M92 E###</code> with the new value. \\
+Enter this new value like this: <code>M92 E###</code>
-<code>M500</code> to save.
+And save by typing this:
+<code>M500</code>.
+Repeat 2 or 3 times to get the number right.

   * filament diameter : measure it from the actual filament used (do multiple measures and average it)
