How to stop your prints from curling up off the platform

There are five things that can be done to solve this issue, and have no fear if done correctly they always work!
1. Increasing the HBP temperature in the gcode should help a lot up it to 110C and then 115C if 110 doesn't do the trick. To do this, after generating your gcode in RepG. Click on the on the gcode tab next to the model tab just above the picture of your model. Then find the line about 10-20 rows from the top that says M109 S100 (set HBP temperature). Then change the S100 to S110 or S115, then build your model.
2. Move your platform closer to the nozzle:
Begin a print such as the 20mm calibration cube without using a raft. And while the the first layer is being printed, adjust the 4 thumb screws beneath the build surface by turning them counterclockwise slowly, while keeping an eye on the filament being laid down. Raise the plate up until the first layer is being schmeared in a nice flat line across the build surface, it should not be laid down as a cylinder, it should be flat. You also may have to stop the print and rebuild it and adjust it again, until that first layer is nice and flat. If you raise the platform too much, then it will most likely stop extruding, so it has to be as close as possible the surface without touching it. Doing this while printing makes it much easier. And be sure not to touch the build surface while doing this because it is hot!
3. Remove all bubbles from your kapton.
4. Clean off your build surface with a little acetone from time to time.
5. Print in a location that is not drafty, or add walls to the side and/or front of your bot to reduce draft.
