Anybody know if there are any accessible large format 3D printers that have big nozzles? (Ie like >1mm)

I briefly looked but there were all crazy $$$ so curious if others know!

1mm nozzles and long leadscrews are generally AliExpress available.

Frame and Z-axis rigidity, vibration damping are going to be complicated, but super stretching an existing 0.4mm CoreXY to, say, 300x300x600mm, isn't that complicated in principle.

I don't think CoreXY scales up nicely because the belts get so long.
