Bltouch not homing properly on SKR13 board (no replies)

Hi there! I'm working on a BLTouch upgrade for my printer and having difficulty getting the unit to work. When I turn the unit on, it glows solid red. When running a G28, the probe deploys but after it "clicks" it just blinks and smashes into the bed.

I'm using an SKR 1.3 board and a new BLTouch 3.1 (I think?). I bought it on amazon and by all accounts its genuine.

My bltouch-relevant settings customizations are:

#define Z_MIN_PROBE_ENDSTOP_INVERTING true // Set to true to invert the logic of the probe.
#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
#define BLTOUCH

I also have sensorless homing on the x and y directions using TMC 2209 drivers

Thanks!
