I had a respectable tech guy come out yesterday to change out the Y motor and pulley system in my JV33 because it was screaming loud while it was printing. After the repair work was done then screaming is even louder than original and the tech guy swares up and down everything was done just right. He said that's how it is suppose to sound. I have another JV33 that he did the same thing on 2 years ago and it made the printer very quiet while it was printing. So I would assume this would be the same thing. Does anyone have any feedback on why my printer isn't printing quiet after this work was done?
