getting prints to stick to whatever the surface has more to do with proper starting height than anything else. .03 to high and you are going to have problems.. add some tape and it takes up the space and all is good.. I used glass with either glue stick or polyimide tape.. Got tired of the Nylon and PETG pullin off the tape and went to glue stick for now.. When I get a print that will NOT come off, just run the plate under water to remove the glue stick and print.For faster removal than putting it in the freezer, spray print at bed level with caned air propelant (can upside down so it comes out as a liquid) it will do the same thing as the freezer but in 5 seconds.. and yes it is costly if you print a lot of things but you pay for speed..
