Current bugfix is version #define CONFIGURATION_H_VERSION 02010300
Provided Config is
#define CONFIGURATION_H_VERSION 02010200
so it may be an old bugfix, but is not current bugfix

You don't specify a feedrate in your gcode anywhere
Try
device.serial.write(b"G1 Z0.001 F1000\n")
You also don't need Carriage Return, only the newline

Anyone got any empty Prusa spools with the cardboard center they would be willing to part with? Just need the plastic parts.
I ordered some refill spools and when the old spool ran out I found my spool are the older non removable plastic core variety, ie not usable for refills

It depends on what your modeling
arty stuff / figurines / miniatures you use blender or zbrush
practical stuff openscad, freecad or fusion360

There are current 4 very different versions of this display. (that we know of, so far)
The DACAI does use the directory called private. The file are in a very different format to the files in DWIN_SET
Unfortunately there is absolutely nothing known about this display, other that it emulates a DWIN command set, the files in private are generated from the files in DWIN_SET files using a uti

%c is the tool number
so it become M600 T0, M600 T1 etc

You have #define FILAMENT_RUNOUT_SCRIPT "M600 T1c"
With multiple tools you need #define FILAMENT_RUNOUT_SCRIPT "M600 T%c"
As documented just above it..
// With multiple runout sensors use the %c placeholder for the current tool in commands (e.g., "M600 T%c")

Could also be that you didn't set #define SERIAL_PORT 0
The chip would always connect, but marlin cannot receive or send any data
And update your ch340 driver

You would need a controlling program or modify the firmware to do that
beds and hotends are separate things...
"Heat the bed to x°C until the nozzle temp sensor reaches y°C." doesn't make much sense
"Heat the bed to x°C and If nozzle temp sensor drops below that temp, it should use the heated bed to keep the temp at a certain point (=y)".
But this means x°C would be exceeded

"Error:MAXTEMP" can be caused by several things
Firstly what do you have the set as the hotend thermistor?
keyword TEMP_SENSOR_0
I believe these old machine used a type 1..
What did you set for MOTHEBOARD ?
I believe those old machines have a BOARD_MELZI
Also unplug the hotend thermistor, does the max temp error change ?
check resistance across the hotend thermistor cable pins while unplug

#define UART3_TX_PIN PB10 // default uses LCD connector

So firstly make sure that your not using serial port 3 for anything

#define EXTRUDERS 1
Up this number
Just defining the stepper driver is not enough as you can have mixing extrudes...

Firmware - Marlin
Also extruders have protection, they will refuse to move if hotend is not hot.
use
M302 P1 ; disable cold extrusion checking
And yes each extruder is a tool
T0
G1 E20 ; move current extruder 20mm
T1
G1 E20
T2

1) your using it wrong, probably due to documentation being out of date
See comment in the code

marlin expect SERIAL_PORT to talk gcode.. end of story.
attempting to use for for anything else will end badly.
All received data is sent to the gcode passer
use LCD_SERIAL_PORT
You have to look at the pin diagrams for your board or the schematic
The tft port uses hardware uart 1

If your using Marlin 2.0.9.5 code
you need to use Marlin examples config for that release ie https://github.com/MarlinFirmware/Configurations/archive/refs/heads/release-2.0.9.5.zip

SERIAL_PORT in marlin are for devices that talk gcode
LCD_SERIAL_PORT is for serial lcds talking custom protocols
Marlin already support a nextion display
//
// 320x240 Nextion 2.8" serial TFT Resistive Touch Screen NX3224T028

So look at all code that references NEXTION_TFT mostly in Marlin/src/lcd/extui/nextion

Read the Configuration files
These is a lot of documentation in the files.
Basic config
set
#define MOTHERBOARD BOARD_BTT_SKR_MINI_E3_V3_0
#define SERIAL_PORT -1
this is the minimal config you need
this sets up the board your using, and all the IO pins for defaults use
And sets up the USB serial port so you can send gcode to the controller.
What next?? depends what you need it to do

Core xy 101:
Two steppers A and B control X and Y together
when A and B move in the same direction X moves
when A and B move in opposite directions Y moves
One of you steppers is inverted to flip X and Y
Your have
#define INVERT_X_DIR false
#define INVERT_Y_DIR true
Try both set to false.

FYI
PA8, //D8
You might have better luck with M42 P8 S255
M42 P66 S255 makes no sense
ignoring the wrong port, you are trying to set the pin you have defined as a inpout for your switch as an output via gcode???
how have you wired the switch?
normally the switch would connect the io pin to gnd with a pull up resistor to vcc
So open it reads high and closed it read low
