Troubleshooting
The following table lists the name of each test in the Built ‐ in Tests suite,
together with its description and a possible reason for its failure. If you
need assistance, contact your Stratasys service provider.
Test Name Description Possible Reason for Failure
Sub ‐ System
Communication
Tests communications between Eden
components.
•
Disconnected communications cable.
•
Faulty cable.
FIFO Non ‐ Interrupt/
FIFO Interrupt
•
Tests the data queue in the DATA PCI
card.
•
Tests the Windows interrupt.
•
If both FIFO tests fail:
Faulty DATA_PCI card.
•
If only the FIFO Interrupt test fails:
Faulty Windows interrupt.
Encoder Tests the encoder ʹ s reliability by
comparing readings from multiple runs
along the X ‐ axis.
Faulty encoder.
System Info Compares the following parameter
values with the minimum
requirements.
•
physical memory
•
available memory
•
free space on disk
•
monitor resolution
Failure of RAM memory allocation in the
printer computer.
RFID Verifies the presence of RFID tags on all
loaded material cartridges, and tests
them by writing to and reading from
each one.
•
Faulty RFID reader.
•
Faulty RFID reader power supply.
•
Faulty or misaligned RFID tag.
•
High level of electromagnetic noise
around the RFID tag.
System Voltages Checks if the following voltages are
within 5% of the required voltage:
•
40V to the print heads by the VPP
power supply
•
12V to the height thermistors by the
VDD power supply
•
VPP power supply:
Faulty head drive(s).
•
VDD power supply:
Faulty height thermistor(s).
Block Filling Analyzes the thermistor readings when
the block is full and when it is empty.
Faulty thermistor.
Interlock Tests the interlock in the printer cover.
•
Failure of interlock mechanism.
•
Faulty latch.
•
Disconnected cable.
Cabin Temperature Tests the temperature level in the
build ‐ tray area.
Faulty temperature sensor (OHDB).
Head EEPROM Tests the read/write capabilities of the
print ‐ head driver cards.
Faulty print ‐ head driver card(s).
Head Voltage Checks the control of voltages supplied
to the print heads.
Faulty print ‐ head driver card(s).
Head/Block Heaters Tests the heaters in the print heads and
in the print ‐ block body.
Faulty heaters or thermistors.
UV Lamps Tests each UV lamp at the High Quality
power level.
Faulty UV lamp.
Faulty UV power supply.
Disconnected UV cable.
Axes Limit Tests the hardware and software limits
of all axes.
Faulty hardware sensors.
Wrong Max Position parameter.
Parameter Sanity Check Compares the values of all printer
parameters (in cfg files) to the required
values.
One or more of the printer parameters is
not within the required range.
Details appear in the BIT report.
Vacuum Tests the vacuum level in the print
block.
•
Faulty vacuum sensor.
•
Vacuum leakage.
•
Wrong parameters.
