I am not using it enough, since I prefer my prusa and felix. It is a acrylic (white/blue) dual head with pi, hires camera and some upgrades (like titan and different head). One head needs new heater block/heather.
Well, I am working on a kossel diamond .... I saw you were working on one for the big box but I only have one diamond. Also after months of use, I am more inclined to replace the big box with a prusa.
I was at their booth, since I am also having a stand at the makerfair.The MK3 seesm good, but not sure much of an improvement on the mk2, the magnetic bed is fine. I prefer the prusa because i made it multimaterial .... so now my big box is no longer much used. (and it is getting sad)
