Yet another way to avoid the firmware troubles is to just get a single stepper driver expansion board and wire the pins to the bank of pins right next to the Z stepper driver on your SKR board. This method splits the signal going to the driver and will now send the same identical signal to 2 stepper drivers which you can then split each to goto 2 steppers and have 4 motors driven by 2 drivers off of 1 set of pins and without any firmware changes. Here is one of my printers where I had this done for X and Y. If you look you can follow the wires from the expansion boards back to the SKR board..
