Yeah the main tech guy there was ready to throw the machine away in frustration lol... he hadn't really heard of the Atomics...so I said "do you mind me having a go at getting it running again". Few atomics later and a replaced bowden tube and all running fine. His settings were pretty bad, running some PLA`s at 220-240 degrees with a 80 degree bed etc!!
Our main use is prototyping hardware for the building industry, window locks etc. Boring stuff but the UM2 is perfect for this kind of fast development.
