I have been a direct part of several Communist and Anarchist demonstrationsWhat ? Does this person even know any of the words he is actually saying ? You cannot have Communism in an Anarchist society . Communism can only exist via a very strict rule and law structure , and even the slightest bit of anarchy would destabilize the whole thing . Why does this person think just about every communist country becomes a dictatorship ? <| sep |> Right , you don ' t care about that , because you ' re new to printers . You seem to be evaluating your purchase the way people evaluate gaming rigs , where it doesn ' t matter who designs your components as long as they have the best specifications . This isn ' t how printers are best evaluated . Printers are tools first , electronics second . Starting with a cohesive , strong base first is important if you want to modify the machine later , because otherwise your modifications go from useful extensions of functionality to desperate attempts at reliability . The MK 2 has several components that are either unavailable on other machines or a pain to get on their own , due to either availability or expense . A RAMBo on its own is well over $ 100 , and an E 3 Dv 6 is about $ 80 . The MK 42 bed the solution to everything in heatbeds , heh is available , but would be a huge pain to configure , as the MK 2 ' s build volume is larger than a typical i 3 , so you ' d have to rewrite the firmware to attach it , as well as modify the machine you do have extensively to attach it . Instead , these things are all in a cohesive whole , ready to go , for only about $ 700 if you buy it as a kit . Not to mention the things that are exclusive to the MK 2 , some of which I ' ve already covered , though another addition is the multi filament system . Granted , it is open source , and thus can be added to other machines , it could take a decent bit of finagling to get in place in other devices , where the MK 2 ' s going to give you these extensions and features before they ' re available elsewhere . Edit don ' t worry about coming off as a bit snippy , I get it . A lot of those things do sound an awful lot like the sort of Dynamic paradigm shift technology ! buzzword crap to an outsider . I fully understand wanting to cut through that to get to the heart of an issue , I do it fairly often myself .
