Hello, Just joined after examining a E3D-v6. I'm working on a 3D printer design (and who isn't that doesn't have much clearance above the hotend. I was impressed with the fact that part of the tube actually fits down inside the hotend which may help support the tube when its bent in a small radius. My question is, how much can I bend the tube (expressed as a bend radius or distance from the bottom of the nozzle to the top of the tube) before it starts causing problems? Thanks for any incite.
