SKR Pro only X,Y0, Z0 Move

I have SKR Pro v1.2 board with V1CNC_SkrPro_2209 firmware flashed.
Identical driver/stepper setup on all 5 channels (UART jumper is only one hooked up)
There are no sensorless pins soldered on the drivers.
Only the X,Y0,Z0 channels are moving. If I swap the cables from Y0 to Y1, the opposite motor engages. Same with swapping Z0 and Z1. This tells me steppers are find and wiring is fine. If I swap drivers around between spots, there is no change at all. This leads me to believe this is possibly bad firmware, which makes no sense. I also noticed that the endstops from the hookup diagram don’t drive the LED on/off for the same channel they’re representing. This could just be the way the firmware is written, unsure without looking at source code.

I’m using the following drivers: Teyleten Robot TMC2209 V2.0 Stepper Motor Driver StepStick 2.5A UART Ultra Silent for Nano SKR V1.3/1.4 Ender 3 Control Board 3D Printer Parts Replace A4988 5pcs : Industrial & Scientific

Also getting Driver error: Printer Halted when attempting to drive Y1 or Z1, but no such error when driving Y0 or Z0

The issue with only X, Y0, and Z0 running is because you installed the wrong firmware. For the Lowrider, you want V1CNC_SkrPro_DualLR_2209. The firmware versions without “Dual” in the title are designed for motors wired in series/serial, so two motors are powered off one driver.

I don’t have an answer for your “Driver error” problem. You might try sending an M122 to see if it spots any issues.
