Topic: loose lm8uu bearings

I am printing a  spare right side y carriage.The bearings are a bit loose. I know that I can wrap some tape around them to tighten them up. Somewhere I saw on here someone had a suggestion on how to print them so they would be tighter but  I can't  find it. Does anybody remember that?

SD3, E3D hotend,linear bearing on x/y axis',pillow block bearing on y conneting rod, ball bearngs on front y axis, fan on y stepper motor.

Kinda, but you could just bump up your extrusion rate slightly.

Do you mean the mulitplier or the flow rate slider?

Multiplier. Flow rate slider might work, but I think you'll have better results with the multiplier. Flow rate slider can cause extruder clicking if you aren't careful.
