 +===== Material =====
 +Extruder: 0.4mm or 400 micron\\
 +(Warning: When buying metal extruders. If there is no teflon tube inside, it will not work with PLA. It blocks when hot)\\
 +
 +===== Configuration of Slic3r =====
 +  * Layer height: never go over 80% of the extruder hardware value.
 +

 +
 +===== Configuration =====
 +
 +Here are some values for my Prusa i3kd. (I just keep them here to remember them)\\
 +Dimensions of the plateform:
 +  * With (X): 185cm
 +  * Length(Y): 170cm
 +  * Height:(Z): 190cm
 +
 +==== 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,…)
