I picked up some Hatchbox PLA and tried to run a few tests to see what settings it prints best with. I started out using the eSUN PLA profile from the quick print and edited the temps, flow and layer height. I tried from 190 - 210C with about 90% flow and .2mm layer height on a few prints of Marvin. For the most part everything looked good, but there are a few small bubbles throughout the print. Being as they weren’t anything major, I attempted to print this G-clamp from Thingiverse: http://www.thingiverse.com/thing:1673030
I printed 2 of these at 200C, and as you can see in the pics, there are a couple of problem spots that appear to be in the exact same spots on both prints. The first is on the back, it looks like there’s some blobs or something happening where the layer starts and stops. The second is on the front face at the bottom corner (maybe some under extrusion?). https://imgur.com/a/J9zko.
The top and bottom came out perfect, first layer also looks good. My retraction is set to 10mm/s, do i need to change that?
