After browsing Thingiverse a bit I ended up on the "Mustache Ring" for my first, proper, test. It has some nice detail and doesn't take too long to print so one can experiment a bit.
|First proper test object. Mustache Ring.|
So far I haven't had any big issues getting the plastic to stick to the printer bed, but changing the filament and using the new Skeinforge settings apparently made a huge difference. All of a sudden it wouldn't stick at all. At first I though I needed to up the temperature in the print head, but that only made it worse. I also played around with the height of the nozzle over the print bed. Supposedly you should have the nozzle touch, or even press a bit into, the blue masking tape, but that just made the PLA bunch up around the print head. Reducing the temperature back to 185 degrees C in addition to increasing the distance a bit did the trick - although now it almost stick too well and I have to rip the masking tape off of the bed on larger objects. I doubt that is right.
I soon realized I was going to need something to help unwind the filament from the spool since I can't go over and unwind a chunk every 15-20 minutes on multi-hour prints. Yet again Aitripper saved the day with his design for the Pocket Reel Roller. He also lists his settings for printing this, but I needed to change those around quite a bit before I had something passable.
Mainly I had to change "Speed -> Object First Layer" (all to 0.2) and "Fill -> Infill Solidity" (to 0.9). Print time was around 2.5 hours.

Hi. How is the Sumpod printing going now. Do you have it working well yet?
I'm still working on that part. The printer performs consistently and when I finish the heated platform I think I'll have the physical part of the build nailed - then it's just tweaking the software parameters left :)
