Brackets. Make a big move. Bad results? Come back by half. It's a binary search for the real world

PETG Problems
It's just practice. The calibrations in Orca are the easy way. Or read more:

I've found for petg, the EM is stupid low. much closer to 0.8 than 0.95-1.0 for the ratrigs. Pressure advance will be on the lower side too.

PETG Problems
What filament tuning have you done? The second pic looks like over extrusion. Petg is sneaky, the over extrusion isn't consistent and instead it poops out blobs like that. I think it's because when melty it has a viscosity or texture with some spring to it.
Tune extrusion multiplier, pressure advance, then retraction.

VCore4 500 hybrid 2nd layer major over extrusion
Put .95 in the extrusion multiplier/flow box. It'll probably clean right up

Then once up and connected. Run the updater from the machine tab. Click to update ratos in its own button, then you can hit update all for everything else. Then do your machine config after the updates.

.xz is the compressed image (xz is a compression format)
The .sha is a check sum file, and the .json is other data.
You only need the .xz

Try an earlier Balena version. Reportedly version 1.18.11 and earlier work. And are you sure you want an old version of ratos?

I'm starting to wonder if having the teeth of the hybrid belts riding on a smooth pulley (bearings) might be doing this. I see it in some of my prints

You'll want more walls for strength, obvs. But I was looking at the top. Turning off single top surface, and going to 6 walls, shows no signs of gapping in the slice, that would ruin a first layer.
