I had success on installing this Armbian for SKIPR also on Artillery Sidewinder X4 Plus machine. The whole X4 lineup uses this custom SKIPR board.
In the Sidewinder X4 board there's no Ethernet port, so to configure WiFi you have 3 solutions:
solder the Ethernet header and connect cable network just to login and configure WiFi, use an USB-to-Ethernet dongle compatible with Linux, use service USB-C port with terminal emulation. 
Always follow Maxim's instruction on take .dtb file from stock image and apply to Armbian distribution.

The Armbian has everything to configure the stock ADXL345 module provided by Artillery just add into /boot/armbianENV.txt the following lines to activate GPIO thru spidev:
 
overlays=rk3328-spi-spidev param_spidev_spi_bus=0
I'm pretty sure the Armbian for SKIPR can be installed also onto Kingroon KP3S Pro V2 and KLP1, and Anycubic Neptune 4 family printers because they use same SKIPR custom board.

I've discovered more about this beaviour... 
If you have Ubuntu Jammy on eMMC and want to boot another OS from microSD it has to be another Ubuntu with mmcblk1 root disk set somewhere, that overrides the boot priority. 
If you try to boot a RaspiOS for Banana it has set mmcblk0 and will not boot.
