My thought is that Onefinity is incredibly busy just keeping their head above water to keep up with production & shipping. I’m sure they’ve thought about a 48" sq. machine, they are probably not missing much. I’m guessing they could theoretically build a prototype together with parts already on-hand. My guess is that someone has probably already thrown one together. And why not? There’s a lot of demand screaming for more/bigger when it comes to cutting area. Point is they could, but may not be prepared to fill the demand on top of what they already have.
And once again @Aiph5u my friend hits the nail on the head. The design is so simplistic that it just makes perfect sense. I’m an OCD tool designer by trade, and I would have been damn proud to have designed this machine. It’s dare I say a near-perfect design. I’ve said it before a few times. I spent a lot of time re-engineering my X-Carve with screw drive & linear rails, and it was as accurate as my Onefinity. But with linear rails bolted to aluminum extrusion, it’s still a compromise. The Onefinity is much more substantial and serious.
