I have tried everything else and this is the last resort. I can change the pattern of the Moire by rotating the part but I think this is the servo motors doing this.
I havenāt seen anything like that on any of my prints. Iāve used Snapmaker3D, SnapmakerJS, and Cura to slice, with similar print qualities. I generally print using the āHigh Qualityā setting (copied to Cura), but havenāt had seen anything like that the few times Iāve used āFast Printā.
What slicer and settings are you using? I see from your posting history that youāre familiar with Cura, customized your print settings, and asked how fast you can push the extruder. I wonder if youāll have the same results using Luban and a slower stock print setting.
I use Prusa, Cura, Simplify3Dā¦ but no longer use SnapmakerJS. This problem is really bad in VASE mode and single walls (as in the picture). Once I do Inside to Outside walls it really does not show much. I have even re-compiled my projects in Fusion360 to use lower and higher quality to see if triangle count changes the effectā¦ Nothing
I adjusted Jerk/Acceleration, all Calibrations are spot on (Steps, Extrusion Mult/Rate) and dimensionally items are spot onā¦ Donāt really push my printer much past 75% of recommended speeds. Also tried linear advanced (iām a metal CNC Programmer so I research and try every available options). I currently use Octoprint to feed my machine (also tried USB Stick and USB/PC Connection).
I have turned on/off one item at a time for just about everything and done test runs to see what happens. I can shrink the effect but itās still there.
So the only thing I have not tried yetā¦ is a TL Smoother.
Now I do have one item to try tonight which is rounding up my E-Steps to an even number and remove the decimals to see if this is an additive problem where it adds up and then rounds up one skipping a step.
I think itās worth a test using SnapJS / Luban just to see if itās software or hardware. If you can get a smooth print using the defaults, then you know that you can fix the issue without a hardware modification.
Which isnāt to say that the smoothers wonāt be a useful upgrade. Iām not advanced enough to weight in on that. I just know that when Iām debugging something complex, going back to stupid-simple can help me figure out if/how/why Iām shooting myself in the foot.
I never had this print picture even with 100mm/s at square parts with sm1.
(tried fast printing at the beginning of my 3d printing experience)
I would say you have a defective machine,- if you are under warranty you should tell the supportā¦
TL Smoothers are a good solution, saw the article of ALL3DP in the newsletter.- Very interesting but i thought there is surely a tl smoother built in the sm1, because of the fine print pictureā¦
Here is a close up of a cylinder tool (OāRing Installation Tool/Bullet) and the surface is clean and no Moire. Did have a couple of drag marks but very smooth.
Watched a You-Tube on the A4988 servo chip and it does in fact studder ever so slightly when moving.
I tried to print as vase and the problem also happened. But it looks different from the picture you posted. I guess modify settings in the software can help in this issue.
Maybe you can post the g-code and settings for printing here so that I can make a try on it.
