I love the watercolorbot!
When I first threaded it, I didn't see the bit about keeping the servo in it's initial position. Needless to say, my first picture was a bit funky.
After rethreading it, it worked a lot better, but the carriage seems to lose some of the accuracy of it's relative position. Sometimes the carriage seems to stutter along. Should I lubricate the rods a bit?
I've posted my second picture. Any advice on how to tune the WCB to get it to work a little better?
