Y-axis layer shifting on my Ender 3 My 3D prints shift along the Y-axis on my Ender 3 3D printer. I don't know what to do. My Y-axis belt is tight, So I don't think that is the problem...
Check for wobble in the X gantry and Y gantry also your Y-axis belt should vibrate like a snare when you pull it and let go. Same goes for your X-axis belt. If that doesn't work see if going back to Cura 4.6 helps (it did for me) and lower your acceleration in Cura (advanced settings movement).
