I cleaned the soot and crud out of the end of the laser housing, put it back together and now when I try to focus by using the “$HZ” command I get this error:
$HZ
ALARM:9
Homing fail. Could not find limit switch within search distance. Defined as 1.5 * max_travel on search and 5 * pulloff on locate phases.
ok
Grbl 1.1 [‘$’ for help]
[MSG:‘$H’|‘$X’ to unlock]
[MSG:Caution: Unlocked]
ok
Does anybody have any ideas of what may have happened? Thank You
