Maslow 4: Large format CNC routing made accessible

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.

The other issue is the heating element. As the nozzle size gets larger, the rate limiting factor is no longer the motion system and whatever adaptive control, but how fast you can melt the plastic.

Most consumer 3d printers can't really take advantage of these large size nozzles, although you could print slowly and it'd still be cool!

For the 'consumer' market, Elegoo's OrangeStorm Giga has 800x800mm 3d printer for less than 3000$ USD. Looks it like comes with a 0.6mm nozzle, but optionally can put a 1mm nozzle on it.

From what I remember of youtube reviewers, plenty of problems though, as the first of its kind. Hopefully they get fixed, but not sure you'd want to get it now if you just want to print.

You want a really long meltzone like a Chube hotend.

I hope you're prepared to spend thousands of dollars on filament.

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