What is this caused by?

Even the infill is coming out wavy, my belts are tight, I've tried turning PA on and off, also MZV and ZV shaper but none are making any difference
Is this the belt ribs being transferred to the print? I used the belts and parts that came directly from Ratrig
It's not the belt ribs beacuse the banding widens if i increase the speed
share your Input Shaping graphs and belt tension graphs

weird thing is on the y graph the z is spiked, is that because the sensor orienatation?
i have tuned flow rate and pressure advance so those aren't it im pretty sure
for more context, im trying to print with a mosquito magnum, diamondback nozzle .4 nozzle, 220c, and 100 mm/s

I've got 75% of thr banding gone with shaping settings, but now I'm trying to fix this infill, it goes disconnected in some spots almost like underextrusion, but I'm only printing at 75mms now.
super slicer?

using soft fever fork of bambu studio
so when i slow it down it looks good, speed it up and it falls apart. im thinking because the diamondback nozzle is pretty flat on the bottom its catching the edge and messing up the extrusion and blobbing up. just a theory though, need a try a different nozzle
rectilinear looks great, its just cubic i think because it crosses over each other and maybe silk filament puffs up a bit too and makes it worse
in my bambu labs x1c i can run cubic all day with any filament through, but it has much more pointy nozzle
That's exactly how belt artifacts work
If i had to guess i'd say you have issues with an idler or pulley somewhere along the belt path.
Could also be a vertical belt alignment issue.
Shaper graphs look great.

i went away after setting my x y frequencies, so not convinced its belt artifacts
now im just trying to figure out why during bridging and infills that cross over the filament clumps instead of smoothly crossing over, prints look great otherwise
added some bracing to the stand its on, that helped too
the only toothed item in the belt system is the motor pulleys. i do see some out of round when it spins but thats because the sets screws push it to one side, i wonder if there is a pulley that has really good tolerances
