couple of things.
150 travel is REALLY fast.
I generally have the travel the same as the printspeed - or 70mm/s at most.
2 - fan should really be either off (first 1 or 2 layers) or 100% (all other layers). The faster you cool the plastic the better the print will be.

You haven't put the print speed.
For pla, you don't need the boxes, you want it to cool and set as fast as possible.

What slicer are you using ?

Oh yeah and it's most likely a bed levelling issue - 90% of print problems with replicators are down to printbed levelling.
Well all mine have been :-)

For infill pattern, use tringular if you have it - just as strong as hexagonal, but faster and easier for the printer to make.

and if you haven't tried flashprint slicer - try it :-)
