Rostock MAX v2 Assembly Guide
The First Layer Height parameter allows you to set the thickness of your first layer. Having a
thicker first layer will help provide a good base to build the rest of the part on as the thicker (and thus
wider extrusion) will help improve the adhesion to the bed. If your first layer isn't any good, the part
could eventually separate from the bed and ruin the print job.
Bottom Clip allows you to tell the slicing engine that you'd like to “clip off” a specific amount
from the bottom of the model. For example, say you've got a 200mm tall model, but you only want to
print the top 50mm or so. You can enter 150 into the
Bottom Clip field and when the slicer generates
the G-code for the print job, it will begin slicing 150mm up from the bottom of the model.
Perimeters dictate how thick the “skin” of your model is. 2 or 3 perimeters are good for most
parts, but if you want a really strong exterior wall, you can make the perimeter count as high as you
feel you need it. To get an idea of how thick the skin will be, you multiply the perimeter count by the
extrusion thickness (we'll get to that parameter in a bit). For example, if you have a 0.5mm nozzle,
chances are your extrusion thickness will be set to 0.5. 2 perimeters will give you a skin thickness of
1mm.
When Avoid Crossing Perimeters is enabled, the nozzle path will not cross a part perimeter
during travel moves. This will help reduce the opportunity for stringing or oozing since the nozzle tip
is rarely over open air. For instance, if the tool path would normally cause the nozzle to travel from
one side of the part to the other, it would cross at least two perimeters and may leave strings of material
in its wake as it moves. If it is set to not cross perimeters, it will cause the nozzle to trace a perimeter
back to the nearest point where it can begin printing again instead of jumping straight across to the new
extrusion position.
