Dual extruder CTC 3D printer unboxing, setup and operation

I got this CTC 3D printer off of Ebay for about 350 USD. It is a Chinese Makerbot Replicator Dual ripoff. In short: it came with lots of loose hardware, had a messed up manual on the SD card and was a bit enigmatic to set up, but I got it running in about 2 hours and it printed relatively well, without any modifications whatsoever! It is definitely worth the money. Here are the steps to get the CTC 3D printer working straight out of the box: 1) Unbox the machine, watch out for loose nuts and bolts. 2) You are provided a hex-wrench. Use it to check all the nuts and bolts on the machine - tighten any that are loose. But do not over-tighten, you'll split the plywood with the nut. The joint should be just firm. 3) Check that the power supply switch (as in the video) is set for your wall outlet voltage: either 230 VAC or 110 VAC. 4) Connect the power plug and turn on the machine. 5) Level the build plate with the "Utilities" menu selection on the machine, follow the instructions on the LCD. 6) Choose "print from SD card" and print an example PLA file. If your print does not stick to the plate, follow these instructions in order of importance: 1) Level the build plate so that a sheet of paper fits between the extruder and the build plate (the leveling function is available from the menu, it is a pretty automated process). 2) Increase the build plate temperature in the Makerware software. 3) Use rafts as print bed. 4) For ABS: pour a fingertip-sized puddle of acetone onto the build plate. Dip a piece of ABS plastic into the pool and smear the dissolving plastic around the plate. This gives excellent adhesion with ABS. It most likely enhances PLA adhesion too. That is it!
