How to stick on the heatbed:
Clean the bare aluminum plate. then make some soap water. Make the bare aluminium plate really wet with it (so no Kapton). But make sure the electronics can't get wet (put a towel over it) I accidently damaged a opto sensor permanently with the soap water. Then peel the sticker while sticking it to the plate. Don't let the sticker sticks itself, it’s hard to separate without damaging itself. Don't worry if it isn't placed right on the aluminium bed, you can adjust it. Now you need a flat piece of plastic. I've used a cd jewel case lid. And press the soap water from the middle of the sheet to the outside. Try to leave no air bubbles. No long strokes from the middle to the outside, just CM for CM. If you do get some air bubbles, you can use a needle pin and press a real tiny hole in it to rub the air out of it.
Printing:
I heat the bed to 60 degrees. And let the print nozzle print real close to the bed so it smudges the first layer in it. Don’t clean it with acetone, It’s too aggressive for the plastic film.. Actually I don’t clean it at all.
ABS:
Today I tested ABS with it… Printed a part 11 x 2,5 x 1 CM with it. Heated the heat bed to 75 degrees and the nozzle to 235 degrees. When printing started the real temperature dropped to 228 degrees and the heat bed to 70 degrees (room temperature = 22 degrees). So I guess the RAMPS electronics or the power supply can’t deliver the current. Nevertheless it printed great. There was a miniscule peeling on the far edge (think it was 0,2 mm).
