Still having issues with the Touch probe? Its not hitting anything during its self test? In fact does it self test OK when powering up? Can you please run the following 2 commands to verify its function :
Start by turning the printer off , making sure the bed is well clear of probe then turning printer back on.
Now provide output of M119
And M280 P0 S600 Does probe deploy? (note in repetier this command is M340)
