Removing the spring can be a solution to resonance issue but:

if you remove them, the bearing on which they were acting is free to slide left and right a tiny bit before being locked by these two screws:

I designed two particular washers to use with the two screws so that they would hold the bearing in place and prevent unintended movements.

Print settings:

• 0.1 mm layers
• 100% infill
• material: i used PCPBT, use high temp resistant one

Give it a chance, it could be the solution, let me know if it works also for you!
