That's odd. Being all the axes the same, it excludes issues with a particular stepper. Certainly it seems a firmware related problem ..and a very weird one.

First: Have you contacted Prusa support via chat ?. That's what I'd do in your case. Also, I suppose that your MK3/S/+ is a standard Prusa printer and not a machine with third party manufacturers mods/upgrades ?.

If Prusa support can't help, maybe you could try a factory reset ( see link below) and choose erase ALL DATA from the menu. Then you loose statistics and Z height presets for the steel plates. so you'd need to recalibrate again. Do it as a last ressource if you can't fix the printer in any other way and, sadly, no guarantee that a factory reset will fix the issue.

After upgrade firmware to 3.14.1 my stepper motors doesnt move properly. When I move the axis from the display, it always move about half of set value. The same for all of axises. It doesnt allow me to calibrate the printer and print. I was trying to downgrade the firmware, but it didnt help. I dont remember my last firmware version, but it was version form 2020 if remember well.

ps. I upgraded also my drivers before flashing new firmware.
