Missing Layers

This is an issue that occurred for me randomly and I had a lot of trouble diagnosing it. I actually have a video on this titled: “Diagnosing and Fixing an Unknown 3D Printing Failure” on my YouTube Channel. This problem can also be known as “temporary under extrusion”.

Replace poorly made extruder

If you were to watch my video listed above, you would find out that replacing my extruder is what finally fixed this issue for me. This is not an ideal solution, but I was using a home-made Greg’s Wade extruder, which likely had tolerance issues and may have worn down over hundreds of hours of printing.

If you are using an extruder that you personally made, or one that is made with lack luster tolerances, I would suggest changing it. As mentioned elsewhere I have standardized to the Bondtech BMG extruder, which I think is well-worth the $100 investment if you plan on 3D printing a lot.

At the minimum you should replace any home-made or plastic extruder with a metal one made by a reputable manufacturer if this problem is occurring (which can be found for under $20 for non-geared). TH3D sells a great metal upgrade extruder for Creality style printers for only $14, which should drastically help with this missing layer problem if you do not wish to buy a geared extruder. You can always reprint your home-made extruder parts after fixing this problem if you wish.
