I have an Original (non-plus with a 3rd-party heated-bed), and am now needing to do a series of prints where a second head for PVA support is the only real option.
That said, since the "official" kit has been discontinued for a while, I thought I'd ask what current options I might want to pursue? I've looked on Amazon and EBAY, and while there are a number of people selling extruder, hot-end and nozzle part upgrades for UM2 and later, I haven't come across one expressly for the UM-Original.
I am willing to purchase an upgrade or OEM-replacement for a later model, but really don't want to waste the time and money purchasing something that won't work with my machine either. Worst case, is there a detailed BOM parts-list of the items somewhere I could use to replicate what the discontinued kit consisted of?
