PDF Rendering not able to work out: server took to long

It is without plots.
Creating everything in a Canvas for 12 pages is no way (I guess it depends only on a few seconds server-time.)
So the only way seems to be having simpler PDF - what a shame, having a cool tool to work with and than you can not show

@Anvil-Team: maybe you can give more server-time (60sec) or increase it just for PDF-Rendering.
