ah - now that's clever.

So what I tried next was wood. I used a piece that was 3/4 inch thick and nice and smooth. That worked well and since I have autoleveling set up it went smoothly. That actually worked the best. I'm have enough 618 for one more print so I'm trying to use it up. I've switched to Bridge Nylon and it's much more friendly.
wood is what I understood taulman recommend - at leats they did last time I went through the 618 specs (got a pound, haven't tried it yet).
So are you using a flashforge - and if so how did you set the autolevelling thing up ?
Very interested in that.
