I'm replacing my control board to a BTT SKR2 and the LCD to a BTT TFT35. I've written Marlin config and uploaded the firmware. Everything so far is working correctly except ABL with my BLTouch (smart 3.0 or 3.1 I think). On my old setup it would work properly, probing the bed in 9 locations. I've put the same probing locations (offsets) in the new config but it goes to the first location , doesn't move the bed closer to the probe and tries to probe in thin air.
I've done M119 and the Z Probe shows as triggered at all times. I unplugged the probe from the probe pins and it still shows as triggered. I shorted those pins and then M119 shows the probe as non triggered. I think the probe works correctly, it deploys and retracts as before and the red light goes on and off as before but I don't know, really if it's working right or if the problem is with my marlin config or with the SKR2 board. Should the Z Probe show as triggered when nothing is plugged into the plug?
Any other ideas?
I have the following settings in Configuration.h:
//#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
//#define USE_PROBE_FOR_Z_HOMING
#define Z_MIN_PROBE_PIN PE4 // Pin 32 is the RAMPS default
#define BLTOUCH
