Joy,

I'm two months into using the FFCP, I have the stock platform not glass, not yet. You need to turn the platform heat off for PLA, you do that in the Gcode after you have created it. After creating the Gcode click on the Gcode tab that appears next to the Model tab. You want to look for 'M109 S0 T0 (set HBP temperature)' in the code, should be in the first 10 or so lines and it will show 110 not 0. Manually change it to 0. You'll need to tack up the surface so the model sticks and use the raft to help keep it down. Methods for tacking up the surface include hairspray or creating a slurry from acetone and some abs filament. I have yet to make the slurry but have used hair spray, be sure to use aerosol, the pump stuff never seems to be sticky enough. If you edited the gcode from the file it saved you would need to reload that code before you start the build.

Hope this helps
