I have a question for a GT381:
I follow all maintenance schedules perfectly. However, recently I have noticed that the print head sounds as though it is making a dragging noise on the round bar behind the print head, where it is attached, when it prints. I clean the round bar with alcohol and grease both sides and in between the print head bearings. It does good for approx 30-50 prints and then starts making that noise again.
I don't believe I am missing anything on the maintenance for greasing that area. Someone mentioned to check the 90 day maintenance schedule, but I do not have one. I searched online and all my paperwork, with no results......
Does anyone else experience this issue after so many prints as well? Is there something I am missing?
