Evening all I recently swapped out the bltouch sensor for an aus3d ir sensor I'm getting some random homing heights.
I have it wired into the z probe connector on the duet wifi 2 board with the connector viewed at the bottom from left to right yellow black green and finally red.
Is there likely to be anything residual in the settings ?
I'm using a cctree (textured blue surface) wondered if this could be causing an issue!
Just wondered if i had covered all my bases before suspecting the sensor at fault have attached my config is there anything I should enter g code wise prior to executing the G28 command within simplify to home all .
It looks as if its doubling my z height as it looks to start printing where it should be starting from lol
