Questions on Replicator 2

[SteveJ]

I just received a Replicator 2 and set it up.  I am having a bit of difficulty printing a part I have created in Vectorworks.  I have several questions.  I would normally call Makerbot, but I think they have other issues on their mind since Sandy.

1)  The PLA wants to stick to the acrylic bed.  I tried using the blue tape, but it wants to stick to that too.  I mean stick so much that it is difficult to remove the part.  Any suggestions?

2) The extruder nozzle seems to be putting out a lot more PLA than it should.  When the extruder moves across the bed, it leaves a think trail of PLA.  I am running it at the default of 230 C.  Any suggestions on how to stop this.

3)  I am trying to print out a small object.  The settings I am using are:
  Quality: high

  Quality: high. Export to S3G, Slicer Skeinforge, Infil: 30%, number of shells: 3, Layer Height:.01mm.

The piece is a 1" tall cylinder-like thing, but when it is printed, it looks like it is the Leaning Tower of Pizza.

Any idea what is causing this?

Thanks in advance.

Share a pic of this and the *.stl file so we could be sure because there are several possible scenarios;

1. Your object leans because it is not centered on the build platform on replicatorg and part of it is actually below the platform with the whole thing at an angle. Just because it was oriented right in your CAD program doesn't mean that replicatorg will orient it the same way (also applies to makerware).
2. support structure on one side has collapsed. redesign with sturdier designed in support structures instead of the automatic structures made by replicatorg/makerware.
3. warping due to uneven cooling. print Thingiverse 29493

I have attached a picture of the object.

My new Replicator 2 had a loose Y-axis belt. It would skip teeth every few layers, creating a leaning part. Make sure your belts are tight and the grub screws on the axis gears (the gears that drive the belts) are tight too.
