Hello !I've a replicator 2X since years.It always worked well.I let it without use since some months, with filament reels.Today I start it, and when making the first straight line before printing, it makes a zigzag. All the printer is clean and greased, as always since years.Do you have somme idea ?Could it be the filaments ? ABS and PLA make the same problem.Thanks a lot in advance.Kind regards,Vincent
