G1 S1 X-265 Y-265 F800 ; move quickly to X and Y axis endstops and stop there (first pass)
G1 X5 Y5 F900 ; go back a few mm
G1 S1 X-265 Y-265 F800 ; move slowly to X and Y axis endstops once more (second pass)
G1 S1 Z-355 F800 ; move Z down stopping at the endstop

G92 Z0 ; set Z to axis minimum (you may want to adjust this)

Thanks all for the responces. Will try dropping the bed out of range but the led is off on the sensor. I did g28 then g29 from past marlin experiences..

Hi. I have fitted a NPN capacitive sensor to the duet wifi. I have powered it 12v from psu and signalled from z min. it works fine on homing but when I go G29 it either says insufficient points probed or error probe already triggered. If I home and then run a M119 it shows Error: Z probe already triggered before probing move started.
I'm probably an idiot and it's something simple. I have set the probe to mode 7 for the z input.
