So, I had 9 successful prints of various objects before this one. I carefully leveled the bed before each print, mostly because its fun but also because I noticed that it drifted a bit between prints. Z axis home, 1 paper thickness off the bed, 2″ in from each corner. Every. Fucking. Time.On this print, I failed to stick around to watch the raft print. I just hit print and walked away (lesson learned). My printer then proceeded to damn near destroy itself. I have two questions:given what I said above about the bed being properly calibrated before each print, what in the hell would cause this? It looks like it printed the raft right on the surface..and then printed DOWN into the bed! I can post the .stl/.gcode files if that helps.where can I purchase a replacement e-axis (extruder) stepper? Monoprice has a short replacement parts list, but that motor does not appear on it. (photo of motor and model in lower images here)If anyone cares, pulling the bed cover off, removing the adhesive with goo gone, and replacing it (it came with a spare) fixed the bed issue. The metal was undamaged.But the extruder motor is dead now. Need to replace it, can’t find one. The silver lining here is that with removing the bed and completely disassembling the extruder assy, now I know how the thing fucking works and feel pretty confident that I can fix it whenever it breaks. http://ift.tt/2qX8T32
