Started out printing nicely but ended up a waste. One of the biggest problems was with the Bowdin tube and feeder. No matter how it was adjusted the unit jammed and started grinding.
Also the nozzle would clog about half way through a 6 hr print which caused a lot of time wasted on maintenance. Getting prints to stick to the glass bed was also a hassle. Even using an ABS slurry the models came loose at times.
I eventually switched to an Olsson block on the hot end but then I had temperature problems.
This printer is now parked.
On the other hand my Lulzbot Mini is a dream. Easy to print with and no problems. Actually the same goes for my Dremel Idea Builder, it just works.
