I have a weird problem that has repeated on 3 different prints. About 1/3 of the way through the print the wrong extruder extrudes for one cycle. This happens for only one z cycle and then everything goes fine but this still ruins the print. I have checked the Gcode and I do not see a case where a T1 or T0 repeat consecutively. I am using Slic3r to slice and Repetier firmware and host. I recently switched to Repetier from Pronterface and Marlin. I did not have this issue with Marlin/Pronterface but I had mid print failures after 15 to 20 hours of printing that I could not resolve, so I am trying to see if Repetier fixes this problem.Using Arduino mega 2560 and Ramps 1.4. Windows XP.
