        this is overloading your cpu.

        change to x16 with interpolation

        dont forget to change the steps/mm

            on a side node your themistors are incorrect

            M308 S0 P"bedtemp" Y"thermistor" T100000 B4138 ; configure sensor 0 as thermistor on pin bedted
            M308 S1 P"e0temp" Y"thermistor" T100000 B4138 ; configure sensor 1 as thermistor on pin e0temp

            B4138 is the default and incorrect for your thermistors.

            try the values from
            https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+2:+Configuration/38

            creatlity uses the same on most of their printers.

              Having changed the motor and thermistor settings, run an auto-tune I started a print again. Unfortunately, the same thing keeps happening

              Here is the updated config for convenience

                can you post the m122 after this happens?
                the first was just after a restart

                  Do you have mesh compensation active during a print? Low Z jerk values can cause stuttering X Y movement.

                      Adjusted steps, checked compensation is on and the pauses are still happening. Its not so much a jerk as a complete stop, wait for a bit and then continue. Here is an m122 during a stop

                        I suggest raising the Z jerk to M566 Z60 and trying again.

                        The low jerk values means that as the Z height changes with the heightmap the XY axis has to slow down to give time for the Z axis to move since it has to obey the lowest value.

                        Reducing the first layer speed can also help.
