If your problem is always on the first few layers, try leveling your bed and adjusting the z-tab so that at max height you can feel the nozzle pressure on a piece of paper, but still move the paper relatively easily. The plastic should look just a little squished when the first layer is extruded.

If your problems are on higher layers, try using a dial guage to measure how far up/down your bed actually goes when you try and move it compared to how far it was set to move and adjust the z stepper in the eeprom to bring it in line.

To update everyone I am using a mirror + blue tape as my bed. I have since been able to make the prints stick, however there are times (when my print head makes rapid back-and-forth movements) that the plastic will start wrapping around the nozzle.

I've tried slowing down my extrusion rate to see if it helps, but I am afraid not.

Does anyone else have any ideas?

What would setting my extrusion weidth = 120%+ accomplish? Thanks!

If Metrocard slides relatively easily under extruder, that was too big of a gap for me to get prints to consistently stick. It's better to visually judge the shape of the first layer (there are good photos on the SD site). Making a couple of such trials after _each_ time you adjust bed (by 1/8th-1/4th turn) will also help you get a sense of when a first layer looks good. By now I keep the bed level by just observing the first layer and making small adjustments once in a blue moon (accurate enough for most prints).

And a clean surface is indeed essential -- before switching to glass + hairspay, I made sure to lightly wipe kapton with acetone before each print.

Also, once you calibrate your extruder, you may want to try setting the first layer to 120-130% extrusion width in slic3r.

Wipe the bed off with acetone and try again.

I do not believe the extruder is clogged because the flow is pretty consistent. However, it's been near impossible to print anything since. Additionally, the bed is level and within a MetroCard's distance from the extruder.

Any ideas?
