X two big peaks
Hi all, I have trouble finding the issue with my X axis. Y graph looks fine, but on the X graph, there are 2 big peaks at 65Hz and 130Hz.
My V-core 500 is placed on a table, but is rigidly mounted to the wall. Any help appreciated

From most of the things I have read, that spike at 125 Hz is usually something loose in the hotend assembly. You need to get rid of it. For me it was the 4028 fan duct rattling as I could not get it to sit flush to the EVA back no matter how tight I made the screw. I have since taken my printer apart to rebuild so I never actually fixed it. Some have suggested sanding both surfaces to ensure they are flat.
You could test this by removing the duct completely and see if the spike goes away. That is how I figured it out.
Check for loose screws as well while you are at it.
