Dual Axis Z1 moves in same direction for all moves

I have a configuration for a dual Z axis using a SKR 3 EZ. When i try the STEPPER_BUZZ STEPPER=stepper_z1 command, or try homing, the motor moves upwards even when it should be moving downwards. It also moves upwards when it should be moving upwards. At first I thought it was wiring, but since i confirmed proper movement on the other Z motor, I swapped the cable completely, and it still does it on Z1 motor. I also plugged Z1 motor cable into Z motor, and when I do it only moves in one direction.

could not compile firmware

I have a new Octopus Pro v1.1 H273. I installed RatOS on a Pi 4b 2GB, and it loaded up to the configurator just fine. I have the Octopus pro connected to the rpi via the usb-c on the octopus, to the usbA on the rpi. I can't get past the Control Board Flashing step in the configurator. When I click the Compile Firmware button, nothing happens. In the developer console, it shows an error:

TRPCClientError: Could not compile firmware for Octopus Pro H723 V1.1: An error occured while attempting to run script: Running board script /home/pi/printer_data/config/RatOS/boards/btt-octopus-pro-h723-11/compile.sh\n\n

I clicked to go back to the board selection page, and selected the first control board, and when i returned to the flashing page to click Compile Firmware, the firmware compiled just fine.
