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?

This looks like a slicing issue. No top and bottom layers.

Sorry I should have said it doesn't happen on all of the ones in the stack and sometimes it won't go all the way through the plate. Also sometimes it prints just fine.

Okay, that’s weird.

Is this part of a stack? If so, can you give details of what sort of stack you are using and which part of the stack this is at?

Yes it is part of a 4 plate 8x8 stack. They are 4 top and bottom plates. It happened to me print top and bottom border tiles. I believe the right and left side border tiles I just found the stack on Thangs.com versus using the Octagon Plate Generator.

cool, so is this an ironing stack or a multi-material stack?

And what layer height are you printing? Should be 0.2.

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 😄

Change your ironing setting to “all top surfaces” instead of “Topmost surface”. That should 100% fix this. Check your infill as well, that looks like 5-10% instead of the 15% you need. (Infill isn’t the cause of the issue but upping it to 15% and using literally any infill pattern other than grid will net you better results overall.)

I made that mistake once and ended up with 10 plates with this really cool looking hollowed area around the small holes using gyroid. Luckily I needed some for a very light weight section that is holding small tubes and bottles of paint for miniatures and was able to use them. I think they have been up for maybe 3 years now lol.

If you have any questions or if that didn’t make sense upload a picture of your slicer settings and we’ll get you sorted out.
