Resin printing question (supports vs. exposure)

I’m resin printing castable wax. Part is roughly 1.2" x 0.7" x 0.1".

What it should look like:

What it looks like:

I have 9 supports along the leading edge, but I’m guessing I must not have had enough. Do I also have an exposure problem?

As an aside, I see there are also two large cracks along the “leading” edge. Thoughts? (EDIT: I didn’t notice when they appeared. It might be post-cure but I don’t know).

The only thing I can suggest is add thicker supports right on the corners. I have had similar deformations and that solved it. Looks like the peeling force popped a couple of supports and the surface reconnected as it was lifting out of the vat.

Thanks. Makes sense.

FWIW, I thought I would add another axis tilt, so there is less unsupported length being printed in the initial layer(s). When I do that, look at how few supports it thinks it needs:

I don’t have enough experience with this to know, but somehow that just feels wrong. I’m going to add a whole bunch more supports just in case.

That it certainly too lean on quantity of supports. Many people are having big issues with later versions of Chitubox doing supports correctly.

Agree. My takeaway is that this tilt is conceptually a more self-supported orientation, but I’m not taking the support recommendations literally.
