I'll diasagree with idig. I was always getting blue crap stuck permamently on the bottom of models.

I recommend Printbite. It should hopefully work with your sensor.
It's a 1mm thick rigid sheet.
You don't need any glue, tape or ever need to use a scraper or worry about release. Get the settings right and it just works.

It sounds miraculous, and compared to all the tape and glue methods - it actually is.
You do need a heated bed - and you've got one so that's good.
One sheet should last the life of your printer, so it's also the cheapest method you can use in the long term.

Skip to page three for list of materials I've tested and the outcome.

Currently there is no better option for pla. I also use it with polyflex, pet-g and all pla variants. Plus a bunch of the newer filaments that came out last year.
Sticking and removing are not things I need to worry about any more.
