This is how is the adxl mounted
is your printer on a wobbly table?

no, it is on the floor...
1e3 is much too low. Your ADXL is not picking up the vibrations because it is loose or something is severely overdampened, like friction on an idler preventing the motions to even reach the toolhead

thanks @elcoj, I had two ball bearings missing from the x cariage, I will try and relocate the adxl, can I pm you once I get the new results? the next few days I hope
and what do you mean by overdampened? I searched online for what it means but no luck
Friction
Analogy: you can't vibrate a guitar string if you have a bit of cotton underneath it somewhere that absorbs the vibrations
Could be an idler or the belt rubbing somewhere, not rotating freely
Or the motor action is not even reaching the toolhead because of a lot of friction
