Is your printer stable? Have you placed the AMS/whatever on top of the printer? This may be the problem.
IMHO, the greater the weight of the objects on top of the printer, the greater the resonances. This should be eliminated by InputShaper, but I don’t know if your printer has this technology implemented. As far as I know, some users put rubber pads under the printer, but I think this can only make things worse.
I would try to lighten the top of the printer and then test printing at the lowest possible speed.
In general, if the printer’s center of gravity is high, it should print slowly. I think this is a standard problem with XY Core printers. However, a good quality InputShaper should eliminate the effect of resonances.
NOTE: Be sure to calibrate the resonances whenever the printer’s center of gravity changes. And also after changing the printer pad.
P.S.
