Solving Glitches

Mystery Plastic

Plastic that broke and fell out during shipping, resulting in a little visible gap in the plastic case
An odd piece of plastic fell out during shipping, and after flipping the printer around I found where its supposed to go. Well, there is a little bottom tab which broke off (which explains why it fell out), but managed to squeeze it back into place. That said, I think having little plastic pieces like these are a really bad idea...

Excess extrusion

Excess extrusion results in wild strands hooking onto the moving print head, ripping whole thing off the print bed.Gah.
Close examination of the print process shows that upon starting to print, a tangible excess amount of plastic is extruded and that curls up on the print bed. It turns out that this causes the "raft" thats being printed to get hooked onto the print head (at one point in time or another), and eventually the whole print gets detached from the print surface and gets stuck onto the print head.

Fortunately, this is quickly solved by quickly pulling off the excess extrusion with pliers, just when the print bed is being retracted upwards. My next raft was rather successful, but the print was unusually rotated by the slicer without my knowledge... more on that later.

Initial prints

Its great that it can print right out of the box. Minor issue with of adhesion to print base without a raft and with larger prints though, but a great start compared to my attempt with Solidoodle.

What settings do you guys print with? Any adhesion like raft? Or heat curtain?
Print failed without raft

First test print!Print head was dragging a ball of broken raft material halfway through the print :(Left: solidoodle (incomplete) 300um, right buccaneer 100um
Print with raft, but a little issue when some strands of the raft came loose and curled up around the print head, later falling off and glitching the base of the cube.
That said, the exterior is much smoother at 100um compared to the 300um I was using with the solidoodle (left, green partial cube). I guess with a heated bed (buccaneer 2.0) this wouldn't be a problem.

Unlevelled print bed. Top appears to be more "squashed" and the bottom started peeling off the surface.
With larger prints, realized that print bed was not level w.r.t the print head. A slight height deviation of 1mm end to end would cause an obvious deformity in the raft, resulting in lesser adhesion to the print bed.

Buccaneer Unboxing

Unboxing of Pirate3D Buccaneer

There were some little issues setting it up like cables popping loose from shipping, but nothing major.
