The safety circuit ensures that the printer is in a safe condition before the printer can operate. In
the event of the safety circuit being interrupted, switched power is disconnected from all motors
and some pneumatic solenoids preventing any hazardous movement within the printer.
The safety circuit consists of the E Stop button and the front cover safety switch. With the safety
components in a safe state, the safety relay allows power to the motors and I/O by pressing the
system button.
