I have my printer fully assembled but am seeing some odd behaviors I wanted to run by the other reprapers.
Firstly, my hub-tri in the center does not lay flat, pretty much ever. It is always tilted to one or another angle and will angle upward as it approaches any of the towers on the side of that tower. I am thinking this is somehow due to the clevis/arm assembly, but unsure exactly what I should be looking for.
I would print new parts and try for better dimensions/accuracy but as I posted in another thread, my Printrbot Simple is temporarily bricked :(
I did notice that when I detatched one end of one of the arms, and rotated the hinge, resistance increased dramatically as the arm turned toward the inside of the carriage. I also noticed that the ends of the arm joints seem to be flaring out in order to fit the washers inside the hinge.
Any tricks to get these to turn smoothly across their full range of motion?
