3D printer 'Empty block' error

[GreenHawk1220 0]

I sent the command '=component.printer3d.addShape(6,6,0,9,7,0,"hardened_clay_stained_lime")',

and ended up with this error

'empty block'

That's it.

What am I doing wrong?

Look again at the coordinate system the printer uses.

(source: http://computercraft.ru/blog/11/entry-349-3d-printer/)

It's a Cartesian grid, meaning that coordinates determine the position of a vertex, not voxel.

In your case, the Z-coordinate is 0 for both points, so you effectively ask the printer to print you a flat face. That's exactly why you're getting this error.

Change the Z-coordinate of the second point from 0 to 1 to add a 1-voxel-high shape.

component.printer3d.addShape(6, 6, 0, 9, 7, 1, 'hardened_clay_stained_lime')
