BLtouch off the board
-
I recently installed a BLtouch onto my Tevo Odyssey rs/pro and when it starts running G29 it does great until it gets to the back side. The last 3 drops to detect the bed are not even over the bed. The BLtouch is about half an inch off of the board and the extruder ends up ramming into the bed because the BLtouch isn't hitting the board first. How do I fix this? Thanks!

@lynnie21 first make sure that in your G31 command in config.g you have specified the X and Z offsets of the BLTouch relative to the nozzle correctly. Then adjust the parameters of the M557 command to limit the range of coordinates probe to ones that the probe can reach.
