Hi guys. I'm having some strange little pellets be deposited on my print as per my images. I'm wondering if anyone could help identify it. I'm using a Robo3D R1 and the slicer is Simplify3D. Printing at 40mm/s, 0.1mm layer height and my retraction settings are 3.6mm at 100mm/s. Extrusion multiplier is 98%, and my extruder is calibrated correctly as per Toms guide. I'm using Woodfill PLA at 195C. I have used the visual guide Mike posted in an attempt to identify what is happening but it's stumping me a little as the only similar thing in the images is the stringing, but I've already played with the retraction settings. The defects not a huge deal to remove, but it would be nice to get clean prints and not have little imperfections on the surface. Could it be a nozzle issue? It's as if it's extruding slightly more than it's laying down and the excess is slowly building up on the nozzle and getting deposited periodically. Could it be something to do with the stringing?
