@nargg,
i guess its a works for some and not for others, i just had an idea and thoughid try it out, is that not what 3d printing is about . i was getting ok results with glue stick, but not enought to justiy it as a permenant solution. i never print in abs so its on pla i have to work with.

@jaykay
glad i could offer a suggestion that i had not seen tried, and it work for you. like you i have multiple glass beds, and are now all covered with kapton, never really had an issue other than prints sticking to well, and the alu being fixed to the heatpad, now as you say i can just remove the one with a print on, put another in, wipe with acetone and away i go again.

@jfk
no that is true, but when heated it has a natural tack that holds the molten pla. i dont need anything ather than a quick acetone wipe every other print and it works just fine. im using float glass (same as in picture frames) of 3mm thickness, guess i just found something that works and im sticking (pun intented) to it. .
