Layer shifting

Hello guys, I'm getting a layer shifting issue. I got that with stock belts ( they were not straight in some places) , then I cut them a bit where they were curved, it became better, but still, if i was increasing speed layer shifting occurred. Now I've replaced belts with expensive gates one. Printer become quieter but still if im trying to print at higher speed - i'm getting issues, you can see in the attached photos. So maybe some one have ideas on this topic ?

Also, belt tension decreased after this print. Before the start measured frequency was 59 Hz after print 53 Hz.

Belts will stretch for a little while before they settle in. Are your motor pulleys firmly tightened down? If they slip, you can get shifts like this

Totaly tightened. I've double-checked everything, and add locktite Also, there is signs of slight belt grinding all over the place.

travel speed might be too high ... keep it max at 400 to be safe

Check your accel also... Too high and you'll get skips

yep, looks like i've got to high with numbers. Can you share your slicer settings? The printer is 500x500 btw.
