What is the deal with this sound? (V2 350mm)

[keen raft]

I have no idea what is going on with this, I know the top layer is a bit over-extruded but I don't think it's extreme enough to cause this.

I have Tap and a toolhead board with accelerometer installed, the build was from the Formbot kit.

When initially configuring the printer I followed the Voron tuning guide in order.
The A/B belts are tightened by feel, I didn't check with any sort of tuner.

Things I've tried:
-Aligning the magnets together on Tap (Not the screws they include, proper magents)
-Un-racking the x-gantry (Though I haven't double checked the squareness of the whole thing)
-Re-tuning input shaping with sweep disabled
-Maxing motor current to what the steppers and drivers are rated for
-Reducing max acceleration to 3k
-Disabling Bed Mesh
-Un-plugging the motors and moving the toolhead around by hand (the motion felt super smooth and the belts looked fine)
-Definitely more, I've been fighting this for like 2+ weeks

Could you share your printer.cfg file including the [extruder] section?

[keen raft]

Freshly downloaded from the printer, I removed the input shaper because I'm testing without that

[desert field]

Input shaper is one of the things I was looking for. There is no point in testing motion without IS. Even 3k accel is too high an accel on a stock v2 with IS disabled.

You have very obvious overextrusion as you said and there are significant cooling defects.

I would be curious to hear what a print sounds like with those two important variables tuned and IS enabled so we can rule out the issues caused by that.

[keen raft]

I can do that

This is what the IS auto-calibration spat out for me if you're curious, still in the middle of tuning flow. (It recommended something like 9.5k for X and 4k for Y)

[input_shaper]
shaper_type_x = zv
shaper_freq_x = 49.2
shaper_type_y = ei
shaper_freq_y = 47.4

Something I just noticed while messing with the printer, there's a slight ticking while the X axis is moving, I think it's coming from the X carriage

Been messing with the Z-Offset and flow on the printer, suddenly it's doing it even with the offset way too high and flow at 50%

The ticking on X

After cancelling a test print, I disabled the motors and tried to move the toolhead, it felt like it was binding for a sec so I'm gonna let it heat soak while I take the dog on a walk and re-square the gantry when I get back

[keen raft]

I finally got around to re-squaring the gantry, moving by hand feels much smoother already so I think that was it

[keen raft]

Yep, that was the problem the whole time 😑

I can finally read the numbers on Orca's flow test

Gonna mark this solved 👍

[keen raft]

Nvm it came back 😞

[jaunty plover]

Just a thought but is this a new build and have you traced all of the way through the XY/AB runs -bearings and the the gears on the motors? Make sure its as tight as needs to be...

[keen raft]

Everything looks good at a glance, I can double check

I've been ripping the toolhead around by hand (with the motors disconnected) and everything feels fine

[keen raft]

Every single point looks good, belts are running where they're supposed to and the idler axle bolts aren't over-tightened so they're running smoothly
