[sudo-prints] TAZ lulzbot printer fixed

I heard the TAZ 3d printer was messed up so i went in there and poked around. I guess the vertical threaded rods for the Z axis are coupled to the Z stepper motors by short pieces of vinyl tubing, with zip ties around them. That's ridiculous. Well somehow (elliot) the Z axis threaded rod on the left got messed up, and got all tangled up in the vinyl hose with the stepper shaft - and everything got out of wack. I moved the vinyl tubing up a bit on the motor shaft, and put another ziptie on there, tightening it carefully with a sneaky method involving pliers and a screwdriver. Then i did the same thing on the right, just for good measure. then i put some papers under the printer on the right, until its base was level with the earth (using the bubble level to check) and then i manually turned the Z axis screws until the trellis or trolley or whatever was also level. then i set the z-axis homing adjuster (the red knob) and adjusted the four corner adjusters of the platform until it was level. I used a piece of paper to measure the distance from the nozzle to the platform near each corner. i didn't try to print anything but i'm sure it will print well.
