An example of why print speed matters...

[mhackney]

I love matte finishes on my black parts. The SeeMeCNC PLA filament imparts a beautiful matte finish - IF you print it the correctly. Take a look at this:

These were printed with identical conditions EXCEPT the perimeter speed. The glossy black part's perimeter was printed at 20 mm/s the matte black part was printed at 50 mm/s.

Think about that, simply speeding up the perimeter print speed resulted in a completely different finish on the part. This is generally true of most PLAs I've printed, they "gloss up" when printed slowly. Dark, opaque colors (especially black) are more pronounced.

Rambo or Duet? Thought the duet eliminated most of the vertical banding issues, just curious.

Sorry! I should have said, this is a stock RostockMAX V3 with RAMBo. I have the new V3 and I'm putting it through its paces in its stock configuration. The banding you see is a Repetier/RAMBo artifact. I don't see those with dc42/Duet.

Hmm, interesting
I will have to try that with nGen. See if it changes the surface finish.
Nice one.
