print bed flatness or lack of Hi All My print bed is not flat enough :( Seems it bulges slightly in the middle, by about 0.2-0.4 mm Is it still possible to print with such a bed by using a raft to level out the unevenness? I wonder if anyone can suggest an affordable material which would be flat enough to work. A UK source would be appreciated.

I just use a peice of 4mm glass on my 2mm Alum heated bed, I also have some small thumb wheel that I use to adjust the height. All works out well.

Seems I have managed to get flatness to within 0.1mm or thereabouts between 0 and 180mm of the bed each way.

I am guessing that is adequate?

I am loath to try sharpen it further as adjusting 1 point seems to modify the entire setting... sleeping dogs and all that.

The glass cost 55$AU. I mounted it using some aluminium channel $4.25AU and some stick on rubber strips.
