All Fracktal printers shipped with MKS 1.4 have DRV 8825 drivers. In case you have to update drivers to TMC 2209, you need to change the Jumper configuration and update the firmware.
Note: After putting putting new drivers with updated jumper configurations, you need to start the machine to connect to OctoPrint. After turning on the machine, do not move any of the components, like xyz axis or the extruder. First, you need to flash the firmware before operating the printer.
