I have calibrated microsteps on X Y Z &E verified vref and leveled the heat bed… so why does my round object in the slicer print like this. Also while calibrating it moved the centered “X” over in the print. I’m Running a GT2560 board with marlin on a Geeetech i3 Pro b. Please help. Thank you in advance.
how does a calibration cube looks like on your printer?
@Christian_Schulz I’m making another one right now. I will post when complete.
I just tightened the the bed and found my x axis rods were loose. Tightened and re calibrated. The print is way cleaner but still distorted at the corners

wtf? what a mess.
i’m no expert, but it seems there are multiple problems.
lets adress one problem at a time.
your top layer is not closed. this may be an under-extrusion or too few top layers.
you should configure at least 0.5 mm of top layers (i you are using 0.1 mm layer height, that would be 5 layers). If that doesn’t fix the problem it might be an under-extrusion.
an under extrusion might also explain some of the other problems, but try to isolate one problem at a time.
@Christian_Schulz I fixed it. I gad a loose pulley on the x axis as well causing that distortion when the x axis had to go opposite directions… this is my first 3d printer. It is printing well now but still need to fine tune. Thank you so much for your assistance! https://plus.google.com/photos/…
