For the last two years, I had problems with inconsistent extrusions on my CETUS MK3. With this simple fix, it now prints better than most of my other machines!

But it's true, if a manufactures makes two variants of the same thing then he/she is making one of them poorly on purpose to upsell an over priced model. Id love to get as much knowledge as possible about 3D printers because I plan to build a large scale one to quickly print RC fuselages.

  • I had some weird gray PLA with some sticky surface. I've printed just few grams using it, but the sticky residue remain on the extruder gear. Over time, small shavings literally glued to the gear, changing the diameter on one side - got similar results to your prints. Simple wire brush and 2 minutes later, my prints became smooth again. Off went the PLA 2kg package.

If you're buying a tool for precision work and it's not even precise to begin with, the company who produces it don't deserve your money.

  • I had the exact same problem with my CR-10 four years ago when I bought it. The extruder gear bore was also off-center. I realized it when I printed larger top layers where I could see gaps between the extrusion lines on some parts and perfect extrusion on other parts of the top layer with a consistent alternating pattern. I fixed it by just buying an Bondtech BMG and haven't had that problem since.

But also the hole in the center of the cylinder looked like an American football. I tightened the X and Y axes belts, and reduced the print speed from 60 to 40. That solved the problem. Also since I don't have a bed leveler. I made sure that my print bed was as level as I could physically make it. That also proved beneficial. Keep up the good work and two thumbs up!!

  • I had a very slight version of this Issue on my BMG clone. I had sinewave extrusion. Due to the high hearing it was very visable on a single wall. I figure it out by printing rectangle/cylinders with the same mm of filament usrd every layer and then, designing a shape with less Filament used every 5mm-10mm etc. These shapes really help you figure out what kind of issue you have. sine eaves /ripples for example mean circular components like idlers etc Random patterns mean lose components usually. I had a long guide on inconsistent layers and how to fix them but noone saw it and it's lost in the forums

I've easily spent 100 hours dialing in every detail, rail, & cura parameter to achieve dimensionally accurate prints. I've been racking my brain trying to figure out what the source of the layer inconsistency could be. I was about ready to concede it was my inexperience, switch to a smaller nozzle to minimize the effect, & accept longer print times. I had looked at everything except the extruder gear. I'm so happy someone with so much experience was able to look at the same problem & solve it. You're the best.

  • Excellent diagnostic Video Stefan! I checked my modded Ender3’s ongoing moire issues and found that the fine ribbed steel DD extruder drive gear had a barely noticeable excentic wobble when turning rapidly! I solved this problem by removing the gear and wrapping 1 layer of common 0.05 mm thick kitchen alu foil around the 5mm stepper motor shaft, then carefully sliding the gear over the shaft again. Since the shaft has a substantial flat side for the anti rotation grub screw, the small wrap of foil shim around the other side of the shaft to fill the minute bore-oversize gap. It me took some patience and multiple attempts to find the correct shape of foil to fit properly. Success! On tightening the grub screw reassembling the extruder and rerunning the stepper at speed

  • Moin Stefan, thanks for the well done findings you presented in this video. I had the same issue on my Ender-3-Pro, where the extruder wheel was prefitted onto the extruder motor axle as fixed press-fit (no lock screws). I was glad to get this fixed with your help and really low overhead. Now my print quality is as expected. After replacing the extruder wheel I ended up with a different observation, where I'm really keen, if this is an issue on your machines either: the new setup grabs the filament with a different spring load than before, so the transportation marks on the filament are of different depth for PLA as well for PETG and thus I need different E steps calibration for PLA and PETG. Before reworking my extruder drive, I had higher E steps values for PETG than for PLA (difference was ~1%), now I have higher E steps values for PLA than for PETG (difference depends on material, ranging from 0.5% up to 1.5%), all affecting slightly my extrusion width. Have you done some investigation on simelar issues?

  • a little something for the Algorithm: In my opinion being able to use and operate metal fabrication machines like lathes or milling machines is a great addition for the 3D printing hobby. Being able to make better fitting parts then off the shelf ones can make a huge difference. And you don't need fancy six figure costing CNC-Machines, conventional machines even the better hobbyist grade machines with some ingenuity are usually more then good enough. For example making an extruder gear on a basic lathe and a drill press isn't that difficult. And using a straight knurling-tool with the lathe, for making the teeth on the extruder gear, is quite satisfying. 😄

  • Hi, Stefan! This may sound stupid to veterans of 3d printing, but hopefully it will help out some newcomers. I was having inconsistent extrusion issues on my Ender 3, and followed your video to diagnose. When I came to checking the extruder motor shaft for wobbling, I noticed that the grub screw holding the gear wasn't secured on the flat side of the shaft. Normally I'm very conscientious about that, so I'll just list it as temporary carelessness at some point, assuming it didn't travel on it's own. It's now extruding well again. Hope this helps someone...thanks!

  • Yep, my CR10 Mini had an offset extruder gear that caused both under AND over extrusion symptoms simultaneously. This was my first printer and it's a really bad way to learn when you have people telling you random and incorrect advice at the same time. Lots will tell you to adjust so-and-so settings, followed by more adjustments. Others will tell you to 'take it back to stock' without a 2nd thought and ignore you when you proclaim it doesn't help because it wasn't right whilst 'stock' When I eventually found the problem, I made it a small personal mission to attempt to instill in as many people as possible that a stock creality machine (really only CR10 and Ender3 at the time) is capable of near perfect results whilst stock, and that you MUST check all mechanical aspects 1 by 1 because until you achieve that near perfect result, you are wasting your time with adjustments and modifications that will only bandaid a problem and don't address the actual cause Unfortunately there's so much noise from people who will just instantly blurt out common bandaid 'fixes' and modification advice that it often does a disservice to people and leads to even more frustration. The one thing I desperately wished for was a proper step-by-step guide to checking every aspect, establishing known baselines and targets and only then moving on from there to actually understand and dial in settings. Not just shotgun random suggestions until it seems to work. It's a very inefficient methodology for having consistent reliable results and improvements
