Just noticed the short belt - particularly on x axis has a very noticeable shift back and forth when the direct of the print head moves back to front (y also but less so). I did tighten these not 12 hours ago and there was no discernible lateral movement - wondering if it might be worth replacing the grub screws that attach motors to frame? I have also noticed that there is what looks like backlash on some interior areas where there are concave areas in the print (fill not meeting walls) although the exterior walls seem to be fine.

So.....
Test print came out fine - no obvious backlash/over/under/extrusion. Set to print my big square object and I had exactly the same problem as previously posted - except this time the top half of the print was only out on the x axis - not the x and y axis. I did notice some very rough section of infill so I'm guessing it caught on one of those again. Temp and extrusion speed was the same for both objects though 100mm extrusion speeed/100mm travel speed, 210 degrees temp.
Maybe a higher temp to get a smoother layer?
I am printing as we speak at 50% scale - maybe the size of the object is part of the problem?
