With (at least) the V1.1.0.15 firmware on the Ender V3 KE 3d printer the PAUSE macro will cause the print head to run too far on the Y axis, which causes a small layer shift when the print returns. I guess the idea is to expose the build plate as much as possible by moving the head as far to the side and back as possible, but the overrun and consequent belt slip unfortunately makes it mostly useless; the main use of this probably being to switch filaments for two colour prints.
Luckily you can fairly easily enable root access on the control pad from the settings menu. After doing this you can ssh to it's IP address with the default password Creality2023.
From there you can modify the /usr/data/printer_data/config/gcode_macro.cfg file (vi is available) to change the details of the PAUSE macro. Find the section [gcode_macro PAUSE] and modify {% set y_park = 255 %} to a more reasonable value like 150. Save the file and reboot the pad so the printing daemons restart.
On PAUSE this then moves the head to the far left about half-way down, which works fine for filament changes. Hopefully a future firmware version will update this; I will update this post if I find it does.
