Hey #3dprinting experts. I was making a little side bracket to hold some eyepieces for a telescope project, and it looks like it will work fine, but there was a small pair of defects in the first layers, which were highly localized, spoiling an otherwise very good first couple of layers. I've seen this a couple of times lately with both PETG and ABS prints. Anyone have any suggestions on what might be causing it?

@brainwagon It's a little blurry but from the rest of the layer it looks like you're either extruding too much material causing the nozzle to drag the layer about a bit or you nozzle height is set too low giving a very similar effect. I'd use whatever tools your firmware of choice provides to double check z height and extrusion multiplier.

It could be grease (fingerprints) on the buildplate. Maybe clean it with lukewarm water and dishwashing soap and do a test on that part of the buildplate. Elmers Purple gluestick is good for extra first layer adhesion.

@brainwagon Is it the holes? It looks to me like the z offset is wrong (needs more squish), and the circular perimiters didn't actually stick to the build plate, coming off when the nozzle crossed them and creating localised spaghetti.

@brainwagon Also: if you haven’t, clean your bed thoroughly.
