You can try changing the solver to "fast" on the boolean modifier. The two meshes are lined up on the Z axis, right?

both are located at 2mm on the z axis

with fast selected

With the stencil selected, in object mode try clicking this button.

I don't think that will do anything, but that's the button that fixes some bad geometry. It will say at the bottom of the screen if it did anything

0 modifications

Then it's possible that maybe your cube is messed up. Maybe you turned it inside out when you were moving the edges around.

figured it out

I think

Ok

for some reason, it's changing the z dimension to zero

I changed it to 2 after doing boolean and voila

nice.

it's strange. I have to have the cube 2mm above the stencil

boolean

works, but stencil is 0mm z

wonder what's causing it to 0 the z dimension after boolean

When you see the location of something, You're actually seeing the coordinates of the orange dot when you have that object selected in object mode. That orange dot is not always where you'd expect it to be. You can move it by: when selected in object mode and click "set origin" "origin to geometry"

Ok. I think I got them all sorted

if you want to look

:( it's not slicing correctly

It's missing a bunch of pieces which means somewhere the geometry is messed up even if it looks good in blender.

doesn't work for you?

weird. works in my slicer

wait nvm

The stencil itself does have some issues, so that could be the problem.

Overhang faces aren't a problem so that can be ignored.

looks like this face disappeared

There's work-arounds, and then there's the real fix of just fixing the stencil.

I didn't realize my stencils had so many issues lol

well it seems to only be an issue on my end

yeah, actually. since i can make a chunk of the stencil slice fine.

using my stl?

nah, that was with my stl that I made just now

oh yea I see

so I moved the z axis location up to 8mm

set them all on the same plane

and it seems to be working

you can always make your cubes super huge on the z axis. the excess doesn't matter.

Nice. I think the skirt is a waste of time, though

well, section 1 is

section 2 is still messed up

Is the stencil's height 100% inside the cube? I just tested what happens if your cube doesn't entirely encase the stencil on the z axis, and it produces weird results

section 1 and 4 work perfect

2 and 3 aren't working

mine seems alright. you can try sending a screenshot with the section 2 cube showing and the boolean modifier off

x face was wrong

Yeah, i mean you just need to make sure they're overlapping. move the screen around to ensure that.

closer, but still off

missing faces

Move the outside edges way out like this.

make the height extra big too

Did are you using the rounded numbers for the x an y positions instead of getting the exact value?

no

I'm using exact

.....that actually worked

why bother making it exact

the advantage is that you can see how big that piece of the stencil will be by looking at the size of that cube. also, it looks neater lol. Once you get good at it, it only takes a few seconds to make them the exact size

how do I turn off skirt/brim?

There's a shit ton of settings in there that allow you to modify your prints. If there's ever something special you're trying to do, chances are, cura has an option for that

Yea that skirt is a waste of time

well it looks like that worked

I re-uploaded to mega

oh nice. you already made the squares in the blend file for reject poison

Excellent. Every one of those sliced properly in my slicer. I added those to my mega folder and my local folder of stencils. I think I know what happened. This stencil has rounded corners so when you were getting the x/y values of the edges, you needed to select a vertex that's at the left-most side of the stencil (for example)

So to get the left edge, you needed the x value of this vertex which is exactly -150.

I selected the face, not the vertex

that's probably what messed me up

Selecting this edge will also give you the correct X value.

but w/e. now you know that the sizing on the outside doesn't have to be exact

That Reject Poison one looks so good

nice :D

Oh I see. I never finished it lol. I just made the squares

bdtr might be tricky

hows that look?

Those pieces will be loose when you print them. that's not terrible, but it's best to avoid.

good call

purple might be a weak point on the stencil since there's not much room to weld.
