UM2 - what is max print size.

[woofy 12]

Sorry to have to re-visit this question.

I have an stl that is 219x219x30mm.

Cura is set to UM2 and I checked its settings are 230x225x205mm, but Cura will not slice it. A slightly smaller size of 218x218 is ok.

This is because of the skirt, you'll have to disable the skirt (in expert settings) to get the full size, else it takes in account that the skirt has to fit on the platform.

I strongly recomend the brim feature for that part as otherwise the shrinkage may pull the corners off the print bed. Also use gluestick *and* heat the bed to 50C.

But if you use too much brim it will be too big to print so just do 2 passes of brim.

Or better - modify your model to have a 5mm wide, .2mm tall (thick) brim on the *inside* of the square in addition to 2mm brim on the outside.
