Thanks for your response illuminarti,
I only ran this as a basic setting in Cura under "Normal" - duplicate outlines was not checked off and I did not have joris enabled.
I've tightened my pulleys, but I'm afraid I may have fiddled too many times to the point where I've lost track of what I've tightened and/or changed. I need to revisit this again. I was following the youtube video on belt tension as well as trying to get my belts to be parallel with the axes. I do have the backup grub screws included in the kit, which I'll swap out on all of the pulleys tonight. I'll also use a sharpie and test to see if they shift.
I haven't checked to see if belts are running up the sides of other pulleys, but have notices perhaps my X-Y short belts are too close to the walls. My long pulleys don't seem to rub up agains the frame at all. Then again, perhaps my pulleys are too far away from the bearings? I read in another post to get them as close to the bearings as possible. Currently, they're pretty far off from the end caps/innner frame/motor pulleys (5-10mm).
I've moved the print head and certainly cannot seem to get the smoothness down that the Ultimaker youtube video shows. This is defiitely an issue for me. I can move the print, but it takes more force than the video. This too is something I need to explore further. My end caps are definitely tight on the axis rods - the slider blocks were also painted - causing the slider block/belt tension levels to not adjust lower - on two of them I have to physically slide them upward/downward with my finger. I'm having a bad feeling paint could be part of it.
I'll also experiment with Cura abd reduce the travel speed. I have the ulticontroller, but did not make any changes to my AmaxX or AmaxY settings. Unfortunatley I did not check this before turning the printer off before having to leave the house. I returned, switched the printer on, and my current Amax settings are X=9000 and Y=9000

It looks like you are either missing steps, and/or having the pulleys slipping. Did you slice it with 'Duplicate Outlines' or 'Joris' enabled, by any chance?
I'd start by making sure that all of your pulleys are properly tightened. Use a sharpie to mark the pulley and rod that it's connected to, and make sure the pulleys aren't shifting on the rods. Even when they seem to be tight, the pulleys can sometimes move. If you got spare grub screws with your printer, you may need to swap out some of the screws with replacements if you can't tighten the existing screws enough to stop slipping.
Also, make sure that all the belts are running smoothly, and not catching on the frame, or running up the sides of any of the pulleys.
Then, with the printer off, try moving the head by hand. You should be able to move it with fairly light finger tip pressure on each pair of sliding blocks - and the required force in both X and Y should be the same. If you can't, then check i) that the end caps aren't too tight on the axis rods; ii) that the axes and cross rods are square and level; iii) lubricate the rods with a little light sewing machine oil.
Once that is all taken care of, try reducing the travel move speed in Cura to about 100 mm/s, and see if that helps things. You should be able to go faster than that, but it looks like it's probably the travel moves between layers that are failing somehow, so start by slowing them down, and see if it helps.
Also, if you have an Ulticontroller, under the control->motion menu - what are your current AmaxX and AmaxY settings?
