Y Axis Idler - JG Aurora A5

cults3d

My JG Aurora A5 started producing a terrible squeaking noise while printing. After opening up, black debris was visible on the Y-Axis idler wheel holder. A printed part from factory. It was suffering from failing layer adhesion, and deformation. I also noticed that the idler wheel was enclosed at two sides by the part, rubbing against at least one side. The orignal factory STL file for this part is available on internet, but installing the same component the same way, that must in time lead to the same problem. I needed: increased total layer adhesion, and washers such that the bearing is used to mount the wheel I made the component a bit bigger using the little more space that is available. Added washers in the model to center the wheel and use the bearing. Printed it for strength (beef up layer width, maximize number of perimeters). It was printed in PLA PRO from REAL. Just because my second printer is running PLA. My JG Aurora is my PETG workhorse. Up to writing, it was still going strong.
