After 8 or so hours and nearing the end the print fails… sigh. This was on a Rostock Max v2. The print failed because as the z-height increased it increased the amount of pressure/torque on the PTFE tubing that guides the filament to the hot-end. My extruder spring was not tight enough so there was not enough pressure so the flowrate of filament decreased. Its all apart of the learning experience and calibration as my Rostock has not printed this yet before. Such a shame as this print was coming along so well.http://ift.tt/1Vt1PmV http://ift.tt/1OZuF7R
