I am thoroughly befuddled. I made the first few prints with my TAZ 4 out of PLA and the parts came out nice and square.

I then switched to ABS and only messed around with the print settings (I did not dare tweak the printer calibrations once it had been leveled out) to figure out the ABS sweet spot on my machine. I then switched back to PLA and it metaphorically seems that "all hell has broke loose". My PLA is not linearly stacking properly and it is warping off the table; PLA seems to make my printer drunk.

The thing that is driving me up the wall is the ABS is working perfectly, which is the tougher of the two materials to work with, and PLA is riding the short bus to struggleville right now. I am at a lose right now, does anyone have any brilliant ideas that I may have missed? Thank you all!
