BTT SB2209 CanBus boards unfortunately have a design flaw that makes it easy to misalign pins in the board to board socket, leading to voltages being delivered to the wrong places.

This can ultimately result in damage to electronics, such as the SB2209 board or neopixel LEDs. I've experienced this issue personally.

This simple attachment prevents SB cover installation with misalignment. Tested on standard Voron StealthBurner.

Replace M3x6 BHCS with M3x8 BHCS.
