Absolutely agree with @3_fall marc . I got a 1260 sigma the other year. Decided I no longer needed my 900 rubi tx so sold that and a tx700 and got a 720 sigma as I do a few 660If you haven’t actually used the cutter yet, I’d be sending it back and upgrading to a 1200.
I personally think that the 900 cutter should be discontinued, it’s an outdated size, and it limits your capabilities quite considerably these days.
I know there’s a couple of common sizes between 600 and 900, but the majority of sizes we seem to install over 600 start at 1m, and I think 1200 is not far off becoming the new 600.
But that’s just my experience.
