New RatRig v-core 3.1 high vibration at lower speeds.
Hello guys.
I have a problem with newly assembled Ratrig v-core 3.1.
After first calibration (flow, e-step) I tried printing regular benchy. It printed OK, but I noticed a lot of ringing on all the surfaces (ringing on corners, a lot of "noise" on straight lines). During printing that benchy tool-head was vibrating making loud noise on certain speeds (~50mm/s). Please look at pic of benchy's hull.
I am using Super Slicer with all default settings.
However when I increase speed (eg. +100%) all noise stops and printer produced very crisp and nice prints. I even increased speed up to +500% and it was printing very well (some ringing but that's normal at this speeds).
RatRig is at work so I will post some more pictures when I get there.
Can You point me in the right direction to fix the issue?
Thanks guys for ALL the useful information here!

EDIT: I noticed some minor play on X linear rail, do you think it could be the problem?

Run shaper graphs (adxl) would show you likewise it is a problem

Thank You VERY MUCH!
I can confirm - after flipping dupont connectors on both steppers and modifying printer.cfg NOISY PROBLEM IS GONE!!! Print quality is normal on all speeds.

No problem! Glad it worked

What did you mean exactly by flipping connectors and modifying printer.cfg?

@florianfeld you need to do both, flip the x/y stepper connectors, and also make sure
dir
is flipped in your printer.cfg (as you've flipped the connectors)could u provide a pic of that in ur printer.cfg?
