you might want to try and join the 2 highest peaks to make sure each belt is tensioned the same. i would say about a half turn on the upper belt and test again. don't go chasing unicorns trying to get them dead on perfect, but as close as you can without diminishing returns 👍🏻
then run your input shaper commands and see what pops out
if you're running RatOS 2.1, you can run the frequency analyser around the 30hz mark and find out what's causing that first peak if you're worried.
Cool thanks. I'll run them again
And I am running 2.1. I wasn’t worried about the other 2 peaks. Should I be?
this second peak might be worth looking at, as you want the shaper graphs to be a single peak and it should settle down towards the higher freqs
here is my X, a little wobble towards the end is okay, but not as big of a peak that you have there
That was 3/4 turn
And this is shaper after.
are you hearing anything rattling whilst it's doing the shaking? this has a lot of spikes, 2 is fine and a smaller one but this one is a bit wild! check your belts are sitting in the idlers, loose bolts, anything around the electronics that might be loose and causing vibrations
Not a thing heard except the oscillation hum
I opened up prusa’s tuner and did the belt strum. It said belt was to tight so trying it again with belt in what it says is in range
New graph after redoing tensioner.
See what input shaper graphs say and send it
