I had recently sent back a k1 with high intentions of going a different route(aka brand).. the max kept calling to me though, I really wanted that size bed. so I forked over the extra and I've been happy so far. It is on its second full day with only one hiccup. it knocked supports loose and turned the floating structures into spaghetti. Not bad, compared to my 1st day with the k1. I have to say, they seemed to have stepped it up for the max. It had the new hot-end and extruder installed with a spare hot-end in a box. I let it do its boot-up, and it's been running wild since.
