Progress on the RepRap has slowed to a crawl and it's really bumming me out. Building from kits is SO much easier than sourcing the parts yourself. I've probably gotten the final cost estimate into the $600-$700 range by now.
Anyway, I need your help. I just need to print out the new X-carriage, get some M3x25mm bolts, buy some MDF for the Y-stage, and get a hot end. However, I don't really know what to get. What are the recommended dimensions for the Y-stage (LM8UU bearings)? What's the best hot-end for 3mm PLA that I can get in the U.S. for a Wades extruder?
Feel free to comment with your suggestions!
