8.5Extruderinfo
Extruder
info provides debug information about the extruder sensors.
It
provides info of:
● ExtrudercoolingfanRPM
● PrintcoolingfanRPM
● Informationoffilamentmovingintheextruder
● Illuminationlevelofthefilamentsensor
- optimally below 100
This
information can be used to check the function of the fans and assess how well
particular
filament works with the sensor.
9 Printer drivers
Latest
drivers and information can be found at
.
The
driver package contains the following settings and programs:

10 Printing your own models
10.1Wherecanyougetthe3Dmodels?
The
best way to get started with your own 3D printing is to find already-created models on
the
internet - they should be in the .stl or .obj format . Fortunately there are a lot of fans and
there
are sites from which you can download a wealth of ready-made 3D models - from a
simple
shaver holder to a detailed aircraft engine model.
3D
models are generally free to download under the CreativeCommons-Attribution-
NonCommercial
(Models not to be used commercially, you must always include the name
of
the author) or for a small fee. We have selected the most interesting sites with high-quality
models
