The Fly-407ZG is supplied with 2 heatsinks. They should be installed as per the image below.
The jumpers should be installed as below. “Common Interpolation” should be used for standalone drivers. “SPI mode Interpolation” is supported for TMC5160 drivers. “UART mode Interpolation” should be used when using smart drivers (i.e. TMC2208, TMC2209, TMC2225 and TMC2226)
Z motor jumpers
- If the Z2 motor socket is not in use install the jumpers as shown.
The board can handle an input voltage up to 32v.
The board that you will receive doesn’t have any firmware installed so when plugged into a computer, the board will show as an unidentified device.
Some boards shipped are missing the bootloader.
If your board has the Mellow logo on the back and when you place a firmware.bin file on the SD card and it doesn’t get converted, then yours is one of these boards.
Follow the guide for restoring the OEM bootloader.
