Rippels and Ghosting on Y-Axis of converted Ender 3



  • @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?
