Thanks, that seems to have fixed it (mostly).

Homing failed error even though it succeeded
I've changed the homing scripts to work with my IR sensor, and everything is working fine. However, every time I run it I get a "Homing failed" error in the web panel and I have no idea why. Does anything look wrong in my homing files? X and Y are as default, using latest firmware (2.0RC6).

Auto mesh/bed leveling not working
I am struggling with my new IR sensor and auto mesh leveling.
I have read the various setup instructions various times, including the blog post by dc42. The sensor offset is calibrated and the leveling routine displays the mesh height points at the end. However, when I actually come to print, the nozzle crashes into the bed. The bed is slightly higher than the Z end-stop point so to me this suggests that the mesh is not being used when printing.
Do I need to disable the normal Z end-stop to get this to work? I'm actually surprised it's still used and would have thought the Z stop would now be handled by the probe, but they seem to be independent.
Really need some help diagnosing this because I don't get it.
