The faster you go the noisier the printer gets. It’s just physics. Nobody said that super fast speeds are for everyone. Some people like super slow printers so they can sleep thru while it prints day and night multi-day prints. But the X1 is so fast, you will regularly do prints in the daytime that used to take 3-4 days with other printers to complete. If that is the majority or minority of people we will soon find out by the success or not of the X1. BTW, the AMS leaves other MMUs and ERCFs completely and utterly in the dust. The AMS just plain works. It’s an incredibly well engineered and well designed multi-material workhorse. Unfortunately I can’t say the same for Prusa’s MMU, or Voron’s ERCF which require constant babysitting and fixing… I know cause I have both… as far as waste material, it’s very similar, which comes with the territory of one printhead. You can get 5 toolheads with the PrusaXL but it will still be slow and cost you $4K+ shipping, and without an enclosure or a dry box for those 5 spools. I’m sure eventually Prusa will add those but then you will be approaching $5-$6K for everything, while still only having just one slow printhead at a time printer, with 5 swappable toolheads… well whoop-de doo…
