Is it possible using the CLI approach to have milled radius not effect actual boards?

[UnexpectedMaker]

For my simpler panellising I like using the CLI instead of coding up the panelisation in Python, but I've stumbled onto an issue where if I include a milled radius, it's effecting parts of my boards where I don't want it to.

I have some half holes cutouts on the edge of my boards, and using :
--post 'millradius: 2mm;' \

Turns this:

Into this :(

KiKit has two features with a completely different purpose:

• there is post:millradius – this is an operation that simulates milling with a given endmill. Its purpose is to validate the shape of the PCB when milling is performed. You can quickly visually check that there are no small features that will be missing or all sharp corners actually have undercut. PCB manufacturers automatically round internal corners without any notice. Personally, I use this to export faithful STEP models into the CAD assembly. And to some extend, it is satisfying to receive exactly what you ordered.
• there tab:fillet – this is an operation that adds fillets to the tabs. People find the filleted tabs more pleasing, though I am unsure about the practical usage of this feature (it doesn't add any stiffness but increases the size of the contact area of the tab with PCB that needs to be post-processed)

Thanks for the quick reply.

Yup, I've used both, but tab fillets only does the tabs, so I get square corners on my frame still - but I guess I can live with that as I don't have how JLC route that on this panel.

But I think the mill radius issue I show here is a bug as it's not actually doing what a mill bit would do in this case, it's just contracting the hole. The half hole shape should not change at all.

Ok, I found that the issue is the size of the mill radius. If I set it to 1.5mm or below, it doesn't change the holes at all, like I'd expect would happen.

So it's a combo of the mill radius size and the hole size. But I still feel a shape like that should never be shrunk down in radius with the mill function.

At the moment, both features are a little bit clumsy. To some extent, they are limited by the current geometry engine. There are plans for migrating to another one for KiKit 2. But it will take a while...

All good - it was easy to work around for my use case once I understood why it was happening.
Keep up the great work!
