I've done a great deal of printing, both with the lidar enabled and disabled.

For PLA it doesn't make a big difference. But when you're printing polycarbonate or PETG, the quality difference is dramatic. Perhaps you have a defective unit?

I also assumed the lidar is a complete placebo having owned the P1P and seeing how well it prints with PLA plus looking at available lidar sensors and their accuracy but maybe it does work? Would love to get a teardown on what components it uses but couldn't find anything online some months ago.

You don't need it if you print slowly, and you don't need it for reliable old PLA. If I squint, I think I can see a difference, but it's marginal.

Thing is, the X1C isn't really for printing PLA. If you only want to do that, you'd get a V400 or a Voron. When I print PC Blend, though, it's... the difference is glaring. This isn't something that needs a lot of testing; with the lidar off, the corners look like semicircles.

Also monotonic top/bottom layers don't fill the full surface, because they have corners on both ends. About like you'd expect, and the difference isn't visible from the outside; external perimeters are always printed slowly anyway.

Vorons are pretty terrible at PLA, not enough cooling and enclosure. They're great Abs printers though and PC blend.

Good to know. The one Voron I've seen in real life didn't have an enclosure; I take it that isn't standard?

The X1 also prints ABS perfectly. I should remember to make a Nevermore filter one of these days, so I can take advantage...
