Applying Kapton Tape To Bed Plate There must be a trick to doing a good job of applying Kapton tape on a printer bed plate…

We built a Bukobot and even with a great deal of care ended up with bubbles under the tape and occasional overlaps. I'd appreciate any pointers.
Try using a solution made for applying window tint, maybe even soapy water.  Squeegee it out, heat the bed for a bit and you should be good to go.

This video demonstrates the process.
