The reliability is largely dependent on how well it’s built. I have a 0.2 and a 2.4 and both have been quite reliable overall, but I did have some issues with my 2.4 recently where the frame came out of alignment (I didn’t tighten the screws enough when I built it), so my z axis belts became too loose. Assuming this will be the only capable printer you have access to, I would highly recommend printing spares of the more critical parts once you have it running. Otherwise, a catastrophic failure could lead to weeks of downtime while you try to source new parts.

US, self employed (HVAC, family business) so if we don’t work, the business (and by extension, us) don’t make any money. That being said, we set our own schedule, so if we want to take time off, we can.

A note on the Mercury wash station: despite being sold in a bundle with the Saturn 4 ultra, the build plate of the Saturn 4 series does not fit in the tub, so I would not recommend it for those printers.

I’m not very familiar with the lower end of index printers. Bambu does exist and seems to work well, but have no support for multimaterial flexibles, and I’m not a fan of the closed nature of their printers.

There are a few other solutions for single toolhead mmus, such as the prusa mmus and the ercf, but those have the problems you mentioned as well.

The only multi toolhead solutions I know of are on the high to very high end (Prusa XL, Voron Phoenix, and there are some projects for toolchangers and idex for the Voron 2.4).
