Thanks for all the replies. I'll definetly be moving to blue painters tape for the time being it looks like. And Chadd, it was actually your thread that gave me the answer. Thanks! I'll be ordering a solid state relay soon. If I have these issues with PLA and a heated bed can I assume I will have them with ABS as well? If so hopefully a SSR will solve that. I'll probably build am enclosure while I'm at it.
