What are the alarm code descriptions?
The most common alarm is Alarm 2. When the E3 homes it sets limits in the firmware. These soft limits
will trigger and not the machine to move past the end of travel on each axis. When the E3 is homed, the
axis is set to X=0, Y=0 and Z-0. Firmware settings $130, $131, and $132 set the maximum travel for each
axis. The E3 default settings are X=450 Y=390 and Z = 85
