Artifacts? Too much jerk?
Unsure exactly problem. Print quality is not great. Flow, pressure advance first layers all good. Height shows wavey layers and artifacts. See picture. Any suggestions?

What slicer ? Settings ? Printer ?
Sorry yeah: slicer OrcaSlicer, settings are stock, just included pressure advance via the line test. Printer is Vcore 4 400.
I think it is usually recommended to leave jerk at 5. Did you change it? There are big vibrations on your walls, so it could be related. Did you try printing a slowed down one?
Have not changed jerk. Slower prints come a little cleaner. Honestly gonna check all the fasteners on the tool head to make sure something didn’t somehow shake loose.
How much cleaner? Can you print one at 50mm/s
Significantly cleaner but not perfect.

Better pic.

still not an amazing picture, try more light and also take 1 with zoom and 1 without, that gets good results
well it looks better
so motion is involved
some VFAs
looks like speed acceleration, something like that





Added new clearer photos. Also pic of speed settings from slicer. That’s default on Orca.
Thanks for helping with this.
No worries
These are the settings from Ratrig defaults for VC4 300 Hybrid they profide for Prusa Slicer.


Those accelerations, are pretty fast.
Yeah, run input shaper.

V-Core 4 400 hybrid

Used SHAPER_CALIBRATE and saved that to hopefully avoid isolate these freqs
Getting this without reducing speed now.

Hmm, I am not familiar with saving input shaper results, because you usally have to pick what shaper to use. Did you follow the guide?
(I usually manually put the values into printer.cfg, but maybe there is a new feature?
This looks a lot better. The overhangs are an area to experiment on. If you dial in those overhangs your prints will be good for 95% of stuff.
Yeah RatOS has changed a bit. There’s a line in the text in printer.cfg that says to either input manually or run that command. Sucks that it’s not in the calibration docs anymore. You have to read a few different things to get all the cal and other fine tuning prompts and commands in.
Thanks for the assist though. Much appreciated.
Oh yeah, hopefully that works out. Remember that your temps are related to speed too, so if you're going faster you can try running a little bit hotter, but it is a balancing act with cooling.
