    Does anyone here have any idea why this might be happening? It looks like a combination of z-ribbing, weird inaccurate wall printing and the odd straight up layer skip. I'm no expert, though. Perhaps there's a simple fix?

    I print with PLA at 210 degrees, 30mm/s. I use Cura but I also got this in Repetier. It's a printer side thing anyway, I'd wager.

    I don't really see any ribbing. Looks more like underextrusion to me. Possibly a partial clog.

    My usual suggestions are:

    -Calibrate your extruder steps per mm:


    - Season your extruder and run an oiler

    - Buy some cleaning filament to purge your nozzle

    - Run a high E guitar string or a brass bristle from a brass bristle brush through the nozzle.

    Thanks for the reply, Mike! That guide was the one I recently used to calibrate my extruder. I was actually getting better prints with the Robo3d default e-steps than with what I calculated.

    I haven't tried cleaning out the nozzle though. I'll do that now.

    in IMG_20150905_203249.jpg (looks like the bottom of the print) it looks like z axis is set to high in either the offset or when it try's to calibrate, what is your print layer height set at?

    That's actually the top of the print. The offset is 1.5mm and the plastic is really squashed in to the build plate. I don't have adherence issues. My layer height is usually 0.1mm as my nozzle is 0.25mm. This was my attempt at printing at 0.2mm

    Can you post what your first layer looks like? I know from my experience that if I was to low it clogged up my hotend.
