Topic: 0.8 mm Nozzle

@pete

My aim is to print using the 0.8mm Nozzle.

• 0.6mm Layer Height
• 1.0mm Layer Extrusion With

The aim here is a rough “printed” look and fast prints.

Using the 0.8mm Nozzle I have the following problems:

• Filament slip -> Higher Temperature and lower speed (5 mm per second works fine but is so slow and 205 degree on PLA are set now)
• Underextrusion -> Flow rate 1.13 fixes it
• The base layer was set to 4mm per second, but it only does that on the base perimeter, the base “infill” still goes faster (I guess 8mm per Second) -> Manually setting the machine to half speed after starting the print works.

The slip leeds to small automatic pauses in the print and a bad look.

My questions here are:

• Do I do something wrong?
• Is there a way to improve the grip of the extruder?
• Should I use an even higher temperature?
• Can I go any quicker with this?

This one is a bit different:

I also have the problem that Cura always wants to add extra extrusion lines on the inside of the print if the walls are “thin”. Can I somehow tell it not to, using automaker (I know that I can make custom GFiles).

Thanks for the help in advance.
