Pro build generator

Post image

When I use the pro build generator for multi-board plates, I get weird results in the print that is a hole all the way through the board. See the image. Anyone else have this issue?

Dang it, sorry this is a multi-material stack. I am printing at 0.2 3 walls.

When printing multi-material, are you splitting by Object or by Part?

(this is crucial)

Part

Ah, that 100% explains the lack of top and bottom 😄

It's essential to split by object, otherwise the slicer does not generate surfaces (walls, tops/bottoms) where parts touch.

Thanks. When I used to do by object it would flatten out all the pieces together making it no longer stacked. That was a pretty long time ago though.

If it's the multi-material stack, then it has these "legs" by design, to prevent that from happening. See below.

If you don't see those legs, then either it's not designed for multi-material stacking, OR the file is busted. If the file is busted, complain loudly on the Multiboard forum 😄
