Tiling does not appear as a cut option in material setup - with a 15.5" Y spoil board - and 5.5" X 36" Y work piece.
using a Genmitsu 4040 w/ 1/4" flat spral bit and 300W spindle.
Begins ok, but fails with STL import!

Are you using Easel Pro? You need Pro in order to do tiling.

When setting your material size, there is a toggle button in the lower left to “Enable Tiling” and you have to turn it on.
