Makerbot R2 heavily modified with full enclosure and all aluminum upgrades from plastic. Also heated glass build plate. Can print in ABS, PLA, or Nylon. Use Garnier Fructese number 5 extreme hold hairspray on the glass for holding parts in place. 60 degrees C for PLA and 100 Degrees C for ABS. Outstanding. No more tape!
I use Keycreater for design work, and Simplify 3D for slicing and printing. Sailfish firmware on my R2. If you have a replicator and you aren't using sailfish and simplify 3D you are missing out. Check it out. Amazing software. Way beyond makerware. Best $140 I ever spent wrt to 3D printing. On the Taz 5 I am using rcbugfix branch of Marlin. If you own a Taz you must get away from the stock Lulzbot firmware, it is problematic for good prints.
