Detail vs Speed

[The Ruttmeister]

I have been playing around with getting more speed out of my
cupcake...

I am still extruding the perimeter of objects at 26mm/s (as with the
last change in the skeinforge settings). But I have moved the infill
up to 32mm/s. (I had observed that the infill was sagging badly, and
decided that it needed stretching. As the filament was actually coming
out faster than the extruder was moving, it wasn't just heat related
sag).

This works very well for parts where detail isn't as fine... although
even the mendel Z driven pulleys have printed well.

Although the height of the first layer is now critical (I'm printing
on hot Al and PI, with the raftless script in Skeinforge. And its
kinda frustrating with the variation in heights on some the STL's...

However I have run into problems with the drive pulleys for the
mendel... it was all blobby and twisted... The details are too fine
for the filament to stick, it gets pulled around. So I have tested and
had sucess with a much lower speed. Switching to a travel speed of
just 12mm with the feed set to 200. The detail was far far better
(although I also switched off Oozebane rather than try and re-
calibrate it).

So I was just wondering if anyone has been doing this? Namely having 2
sets of settings, 1 for speed, 1 for the fine detail where needed?

And now to try making a second profile on Skeinforge, marked makerbot
ABS-fine.
