Need help: random horizontal lines when printing curved objects.

I'm having a reoccurring issue with my Tevo Tarantula. When printing say a calibration cube I dont see the lines but when doing anything with holes or curves I see random verticle lines. It will usually be a line or a group of lines that are thicker than the rest of the object.

Tevo Tarantula
.4 nozzle
.3 or .2 layer height( tried both)
e-sun pla+
205/60
slic3r

Thanks,
Eric

Hi Eric,

What I think you are seeing is short spurts of over extrusion caused by lots of retractions. If you look at your sliced model, compare the extruder path with the actual model. If the thick parts are at the beginning of the layer, that's your culprit. Reduce or turn off retractions.

Also looks like you may have a little z-wobble.
