For all the people out there who put kapton tape down on their print bed, I just discovered a little thing you can do when preparing the bed for a print.

Okay, so you know how there are always little bubbles that form when the bed heats up as a result of little tiny pockets of air you can't see when you first put the tape down? These can make the bottom of your print come out with lumps/indents which is obviously not ideal. So what I did before my last print was heat up my bed to 110 (which is the temp I use when printing) to make those bubbles show up. Then I took an exacto knife and just poked each bubble. A needle would probably work best, but I had the knife on hand. When you poke it, you'll feel a little click from the blade piercing the tape. Once you've poked all the bubbles, take a credit card and flatten out the tape (like you probably normally do when putting the kapton on). The air in the bubbles should come out of the microscopic holes you made. Sometimes some bubbles stay somewhat intact, but you can just repeat the process. Took me like 2 minutes and my print bed looks much better than it usually does.
