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.
Description
Tests communications between Eden
components.
•
Tests the data queue in the DATA PCI
card.
•
Tests the Windows interrupt.
Tests the encoderʹs reliability by
comparing readings from multiple runs
along the X‐axis.
Compares the following parameter
values with the minimum
requirements.
•
physical memory
•
available memory
•
free space on disk
•
monitor resolution
Verifies the presence of RFID tags on all
loaded material cartridges, and tests
them by writing to and reading from
each one.
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
Analyzes the thermistor readings when
the block is full and when it is empty.
Tests the interlock in the printer cover.
Tests the temperature level in the
build‐tray area.
Tests the read/write capabilities of the
print‐head driver cards.
Checks the control of voltages supplied
to the print heads.
Tests the heaters in the print heads and
in the print‐block body.
Tests each UV lamp at the High Quality
power level.
Tests the hardware and software limits
of all axes.
parameters (in cfg files) to the required
values.
Tests the vacuum level in the print
block.
