Agree 100%.

Here's something handy to know.!! . . . . Friend called other day who I made a large sheet cutting router for and owns a timber yard. He supplies a local school/collage with Exterior ply for there laser cutters and mentioned that they had been having problems with it cutting thru.? Turned out it was glue was interfering with beam and reflecting it back or something crazy Changed to marine and went away.!! (Could have been tuther way round but get the gist.!!)
