    Strange blobs/tramplins on top of corners. Please help!

    Hi. Just got myself my first 3d printer, delta Kossel mini. Trying to print with PLA that came with it. Cant get rid of some strande blobs/tramplins on corners. Print temperature 176 C, hot bed at 56 C, 0.2 layer, 0.4 nozzle. Played with retraction, speed, extrusion but still have this problem.( Maybe still to mush extrusion? Any suggestions?

    Those are some small parts. What speed are you running? The bottom of that one on the right looks under extruded. The extrusion temps seem low.
