Feedrates are not 4-dimensional, and yes this makes them a bit inconsistent. But physically the 4-dimensional speed would not make any sense - for example, slowing down the E axis while speeding up the X axis would not maintain the same "overall speed" in any meaningful sense.
So, feedrates work differently for:
Moves with a nonzero X, Y, or Z ...

First of all, make sure that you have correctly identified the X and Y axes, and that the stepper motors (and end-stop switches) are connected to the correct ports. The hot end moves on the X-axis, and the bed moves on the Y-axis. If you connect the X and Y motors the wrong way round, you will get reversed text.
If the X and Y motors are connected to the ...

Normally you wouldn't use the MANUAL_xyz_HOME_POS at all.
Home your machine.
Use a caliper or ruler to measure the distance between the nozzle and the edges of the print bed in both the X and Y direction.
If the nozzle was off the bed in both directions, input these measurements as negative X_MIN_POS and Y_MIN_POS values.
If it was over the bed in either of ...

I think I might have found it - PID problem (heater has a PID loop). Standard values are 32/3/85 (P/I/D). Just watching the temperature, I noticed there was a lot of overshoot.
It appears that to continue after a temp wait, it must stay within some limit for a period - don't know either number. But, presumably, it wasn't.
There is an autotune PID gcode - ...

I believe (from reference) the default steps per mm for the FLSUN 3D Cube are:
X, Y, Z, E0
#define DEFAULT_AXIS_STEPS_PER_UNIT { 100, 100, 400, 150 }
Default marlin 2.0.x are:
X, Y, Z, E0
#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 4000, 500 }
Such a ...
