Rippels and Ghosting on Y-Axis of converted Ender 3

@4lathe not doubting your personal results but that photo doesn't look to be lit from above, and so wouldn't exaggerate any z-wobble?
It's like what I said originally. Apart form some dubious connector, wiring, and firmware setup choices it's the quality control which is the Creality machine's weakness. Get one with most of the parts bang in the middle of spec amd you get a great machine. Get one with a vouple of rough bearings, tight or sloppy bowden tubing, amd two bent screws and you'll be making up the cost saving offered by buying an ender in you time alone at minimum wage! ...but this problem solving does give you a huge body of knowledge for future problem solving.

@devleon after all this, I would love to find out what the ender was like that produced this cube you posted above. That is a great print imo. Was it pure stock? If do we know its not the wheels or the bearings or sag, etc. My ender 3 has only been modded with direct drive and the duet maestro. It definitely printed at least simple things better before the mod. https://cdn.thingiverse.com/assets/c9/8d/6f/3e/d5/featured_preview_speedDrive_cube.jpg
This is where I got the picture from, a direct drive mod: https://www.thingiverse.com/thing:3816051
They definitely done plenty of upgrades to his printer already, as it's outlined in the description.
I wonder what you mean with when you say your ender 3 printed better before you did the mod. Are you saying it's printing worse with the Duet?

What country are you based?
I'm from Germany.

@devleon here is the premium supplier of v-slot wheels:

Ooznest probably ship to Germany without much issue - but you can probably find that in germany too:

@DocTrucker that pic was the one devleon posted above. Not from my machine. @devleon yes other than retraction issues on complex parts which were improved by the direct drive, the surface quality is worse. I use duet wifi’s on my railcore zl and some deltas with no issue for years. However myfirst maestro
-
Sorry. The first maestro and direct drive together have created a poorer surface finish than previously. Anyway I don't want to interrupt your thread but I still see small micro interruptions on your surface finish. They may be less than .5mm but still look like small vibrations or fluctuations in extrusion. I have something similar and was just hoping to get a finish like that cube you posted. Watching your results.

Hmm. Wierd. Maybe it's related to different speed/accel/jerk settings and how Duet probably handles things like acceleration differently in comparison to marlin?
Regarding the very small surface artifacts, that's my cheapo 5015 blower fan vibrating. Without the fan running, it's gone, but of course I can't print PLA without any cooling. I have a replacement in the mail.

Just went and read the thingiverse page you referenced. Did you look atthe before and after photis in the tl smoother section? His theory was bowden tubes absorbed some of the extruder fluctuations that got highlighted with direct drive. Tl smoothers fixed it for him. Not that we need tl smoothers with the duet boards (well the maestro drivers are different from the duet wifi) but maybe theres something there?
-
@4lathe yes sorry I was trying to say I don't doubt that you have had good results, and secondly that the shared photo wasn't ideally lit to show z-wobble defects. I wasn't saying ir was your part.
-
@DocTrucker
I'll try to print a part in a similar color and hold it just like it was held in the photo. Then we'll see if it hides the Z-wobble or not

@devleon I've found it very difficult to photograph these patterns myself. Not got great lighting yet but I have had to get macro extensuons and cheap tripod!

Well, I do have a macro lens and a tripod, and can probably mcgyver some lighting, let's see what I'll come up with

Also, that print doesn't seem like it's printed with a 0.2mm layer height, the lines seem quite thick. Maybe 0.32?

Do we have a Z isolator designed specifically for Ender 3?
All the designs on Thingiverse seem to aimed at the Prusa or other models...has anyone actually made one for the E3?
