so ive been fiddling with my MKS-Sbase 1.3 and a BL touch, i have it wired to the Zmax pin, P1.23 and 5v and ground, i have a physical endstop connected to Zmin and have the touch probe configured to use P1.29 (Zmax)
every time i do one probe to test for offset it retracts then drops then blinks red. i have no idea why
someone please help, my firmware config follows.
also any tweaks to my config would be helpful

## BL Touch Usage G-Code (to run bed level compensation)
#G28 X Y ; Home X & Y (to min)
#G1 X100 Y100 ; Move to bed centre
#M280 S3.0 ; Deploy probe pin
#G32 ; Probe the bed & enable compensation
#G1 X100 Y100 ; Return to bed centre
#G30 Z1.5 ; Move down to find bed and set Z home offset. NOTE: Adjust "Z1.5" to be the Z-offset (in mm) between the probe and the nozzle; experiment!
#M280 S7.0 ; Retract probe
#M374 ; SAVE compensation grid
# BL Touch Commands:
# Probe Down M280 S3.0
# Probe Up M280 S7.0
# Self Test M280 S8.4
# Release Alarm M280 S10.6
# If compensation isn't working after restarting the printer, enable using:
# M375 ; (you MUST home after using this)
## NOTE: Add these lines to 'machine start' gcode settings in slicer, as replacement for "Home X/Y/Z" (G28):
## G28 X0 Y0 ; Home X, Y
## G1 X100 Y100 Z50 F1500 ; Move to bed centre
## M280 S3.0 ; Deploy probe pin
## NOTE: Adjust "Z1.5" to be the Z-offset (in mm) between the probe and the nozzle; experiment!
## This is how you adjust nozzle printing height!
## G30 Z1.5 ; Move down to find bed & set Z home offset (Zxx=probe-nozzle offset)
## M280 S7.0 ; Retract probe
## G1 Z15.0 F9000 ; move extruder up 15mm
