Here is a thread of my unboxing and first print(s) off the Robo C2. I had said before how I thought the machine was overpriced considering size and lack of heatbed....I stand here to eat my words . Suprisingly sturdy and smooth running machine. Same issue as the R2 (at least that I saw) with Jerk and Accel being to high. I put on (without trying the original) the new fan shroud available from Robo3Ds thingiverse and will be putting some hours on the machine. I'm impressed by the packaging and general first impression. Even more so than with the R2. Any questions ask away.
