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)

• Layer height: never go over 80% of the extruder hardware value.

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

In pronteface.py: To get the values from the firmware, type

M501

Ex:

>>> 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

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:

M92 E###

And save by typing this:

M500

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)
• filament extrusion multiplier: to lower (<1) or raise (>1) the amount of filament extruded

Use these values to play with the layers' heights for parts of the model (perimeter, fill,…)
