Weird Tail
Using a VCore 3.1(ish) 500. Added the front end tensioners rather than on the toolhead.
I have behavior on my input shaper graphs that I do not know how to troubleshoot.
These are the graphs as they were last measured. That noise at the upper range, I have no idea what that is. They're not perfect outside of that, but I don't think chasing down that little bump on the lower end is going to be worth it unless I get the bigger noise down.
What confuses me even more is that I ziptied the umbilical cable and it made the x-axis graph worse. I will post that graph in a follow up message to keep the two separate
I think I'm really close! And missing something significant

Graphs before securing cables
Ok removing that zip tie didn't change anything lol
I don't know if the belts are overall too tight / loose
Been working on it a few hours now, back and forth
Still no clue if they're too tight / too loose
Constant layer shifts, still can't find the issue
the layer shifts have been moving the print towards the front left
You're overtensioning the belts like crazy. If your motors aren't supported like in vc4 i suggest to check condition of the motors
And release tension A LOT
expected range of mzv freq is around 45-50 on a 500, not 116hz
That's interesting because as I started to loosen them I got way more layer shifts
The answer might have been: really dumb
I loosened the screws on the carriage, before and after
it is still imperfect but this might be something that i can actually make progress with
