pei - that's the bugger !
would have mentioned it, but for the life of me I could not remember what it was called yesterday :-)

Yes definitely worth a try.
Just remember - none of these things are magic. So you will still need to dial in your specific printer for each print surface.
I bought a cheap sheet of pei last year to test.
Can not find it - so will probably buy another one lol.
I think a 200x200 sheet with self adhesive backing was about five pounds off ebay from china.

magigoo and dimafix both work well, particularly for items that don't have a lot of surface area on the bed for the first layer.
