2.4. SIMPLE MODE
negative value will offset all layers by that amount. The correct solution
however is to fix the end-stop itself.
The optimal Z endstop position is where the nozzle tip barely touches
the surface of the bed when homed. A sheet of paper makes a good gauge
for this very small distance. It is not recommended to use this setting to
try and improve layer adhesion, by ”squashing” the bottom layer into the
bed, instead look at the suggestions in subsection 2.3.
Firmware. As selected in the wizard (see p.29),
G-code flavour
defines
the dialect of G-code generated.
Extruder.
Nozzle diameter
was defined in the wizard (see p.31).
Retraction. Unless the material being extruded has a very high viscosity
it may ooze between extrusions due to gravity. This can be remedied by
actively retracting the filament between extrusions. Setting the
Length
parameter to a positive value will cause the filament to be reversed by that
many millimeters before travel. The retraction will then be compensated
for by the same amount after the travel move, before starting the new
extrusion path.
A value of between 1 and 2mm is usually recommended.
Bowden
extruders may need up to 4 or 5mm due to the hysteresis introduced by
the tube. Setting the
Lift Z
parameter to a positive value will raise the
entire extruder on the Z axis by that many millimeters during each travel.
This can be useful to ensure the nozzle will not catch on any already laid
filament, however it is usually not necessary and will slow the print speed.
A value of 0.1mm is usually sufficient.
Start, End and Layer Chance G-codes. Custom G-code commands can be
run before a print starts and after a print finishes.
Placeholders can be inserted in the G-code commands

. For example
[next_extruder] would return the index of the next extruder.
The RepRap wiki is a good resource to learn about the variety of G-
codes available:

.
Note: Be sure to check that a given G-code is valid for your firmware.
