Z-Probing outside of bed area =(
-
I recently built a a core xy machine - everything was working fine but I must have broken something in the config.g on my last few edits -
Now, when I hit "home all"....X&Y home fine the machine then attempts to do a Z-probe (Bltouch) but it's outside of the build plate area. Typically it moves over the build plate a bit prior to homeing Z but no longer does that.
The z-probe is offset about x-45mm, y0 from the nozzle. I entered the z-probe offset in the config.g so I'm not sure what's going on. Any help would be greatly appreciated!
here's my config.g

the position of z probing is in the homeall.g script
