Siboor's kit is an accumulation of hardware from different vendors. Siboor has done little to no preparations to make those hardware parts work together. Double check all wiring.
Fan plugs might have the wrong polarity. They won't require new crimping, just changing the pins on the JST plug.
Dec' 23 has seen an influx of kits that shipped with faulty drivers. If your stepper drivers randomly fail (early into setting up the printer), power it down and contact Siboor. There has not been a fix for this in place. If your drivers are bad, all of them need to be replaced. (Bonus points if you send me a DM on discord with high-res photos of the drivers)
Powering off the printer needs to be done by shutting down the printer through mainsail or ssh, waiting until the host led's stop flashing and only then flipping the switch. Otherwise, changes to your configuration might not be saved. See Powering off the Gemini V3 for more details.
Swap the ports for the board-fan and the hotend-fan so the hotend fan can be controlled

Gemini comes with a hid-flash bootloader, so BOOT1 needs to be HIGH to put the device into HID-flash mode. (https://github.com/Arksine/STM32_HID_Bootloader) – the opposite of how the DFU bootloader works?
Klipper on all Fly images is outdated. If you know how to setup kiauh yourself, use mellow's stock armbian image or build your own armbian image using my patches.
