Interactive Build Plate Levelling - Print Aid
by whpthomas, published
Having problems with your first layer surface finish? Is it clumpy, stringy and inconsistent? Use this interactive single layer print to fine tune your build plate adjustment. Works like a charm!
UPDATE Jan 19 2013
I have uploaded a new shape to try which provides an area over each level adjuster.

I recommend using your regular Makerware/ReplicatorG settings with a 0.2 mm layer height.
Run your bed levelling procedure, then run this print. I wait until the perimeter has been printed and as the extruder starts doing long strokes. Starting at the back, I adjust each levelling screw, one at a time.
The procedure for each level adjuster is as follows: lower the build plate by adjusting the level adjustor (on the Replicator 2 this is done by tightening). Do this until you start getting stringy strands of filament, then gradually raise the build plate (on the Replicator 2 this is done by loosening). Do this until you get a nice even finish. As the extruder fill pattern approaches the sides, adjust each side accordingly.
You should aim to get a consistent flush surface with no gaps, and minimal bumps. The beads of filament in the infill should also be firmly bonded to each other so you can't tear them apart easily.
