Just performed major alignment work on my printer today and ran another test.... And my second bump suddenly decided to join the party... (before and after pics) My two peaks are so close, not sure if I want to tempt change the tension to get closer. Understand the 125hz is something to do with EVA

vcore 3.1 500 but I think it would be the same (maybe slightly different in frequency range)

so i guess i should have a small bump before the peak. ill try to look in to it this weekend. probably loosen the belts a bit i guess

I think mine came back after re-aligning the Y-Rails to be parallel. Loosened the one rail and moved the gantry back and forth with the belt off and then slowly tightened back down from one side. Then repeated on the other Y-Rail. I also corrected a skew on the frame of 1mm for the comparison of the cross-measurement corner to corner.

seem strange that my rails would have moved after i changed the belts. its running smooth. ill run it like this for now, will check everything as soon as i got some free time
