Introduction

Howdy from Texas. I'm new to the 3D Printing world. I just puchased the ROBO 3d R1. It's really great. I do have a few questions.
- How Smooth can you get the sides? and whats the trick?
- How small can you print? are there temp, speed, distance differences?
- Do I need to get a different print head for smaller objects?

Loving the equipment though!
