This changed the geometry of the hot ends, and made it imposible to keep the machine calibrated. I did print these at 4 walls and heavy infill, vs I think the originals (using same brand of filament, but different batch) were 5 or 6 walls. So my best guess is my print job was just bad on these mounts! I looked at the mounts I printed years ago that were in similar use and they had zero indication of this kind of deformation. I am printing at no higher temps, and the current to the steppers are no higher. Uneven indent in the front at close to.Half way through that the screws were loose again!Īfter the print I took the extruders off (both were getting loose, even the one not being used!) So I readjusted the height and printed the mount. I didn’t use any thread lock on the screws since I do remove and adjust the Extruders now and then, but I’ve never had them get loose like that. I noticed that the screws for the E3D Titan Aero which holds the stepper and such in place on the mount were finger loose all of a sudden. 1 hour before this the head was perfectly aligned… what happened? When I did the head crashed on the same extruder into the glass. I printed a new fan ducts for the new Hemera mount, and went to print the mount itself. Mainly for the next change I am making – installing an E3D Hemera extruder. After precisely calibrating the machine so that the extruders were perfectly aligned again and had zero Z offset, I went about printing and designing things.
