I have hit the last straw with my E3D BigBox. If you are looking for a project that will take absurd amounts of time to decipher where parts are located in the 10+ boxes with 30+ bags, where these mystery parts then go that don't match instructions, have to guess how they are assembled, only to have all of the printed parts be 1mm or more off in critical dimensions is a colossal joke. While I respect what E3D has tried to do they have failed miserably on the execution. I don't care what the excuse is, I did not spend my money on a printer that is of this low quality. Every Assembly step is a fight, every piece assembled a minor miracle if nothing breaks and doesn't have to be disassembled multiple times to correct manufacturing flaws. I have had a colleague print every printed part that mates to a rod because the holes were 6.8mm at the largest (measured with digital calipers). Every part he has printed fits perfectly, with no issues. Three bearings were missing ($30 US), two printed parts are no where to be found (IR sensor & X-idler), and I am short multiple M3 and M4 machine screws and lock washers (yes I know there is a extras bag in the extra box, yes I know stuff had been shuffled from other bags to there too). Maybe my experience is the unique and special snowflake of the batch but I have been supremely disappointed by this experience. TLDR; Buyers beware, unless you have oodles of spare time to waste on a garage hobby that will ultimately collect dust, this is not for you. If you are using this for business, buy a commercial grade 3D printer that comes preassembled (or has a QC department) and has a proven track record of working. Edit: I received my printer in the July 2016 shipments and is what I believe is called the BigBox V1.1.
