Z402C System User Manual
•
Are any of the lights on the control panel illuminated?
If the error and power light come on but nothing happens after that, shut the machine off and
turn it back on again. The machine should come online. But if it does not, please call the
Service Department.
8.5 MY STARCH-BASED PARTS ARE UNUSUALLY “CAKEY”
•
Is the saturation too high?
If your parts (especially bulky parts) are unusually difficult to depowder, too much moisture
has moved from the part into the immediately surrounding powder. You may have the
saturation levels set too high for this type of part. Using a lower maximum setting will fix this
problem.
•
Was the part left in the bed too long?
If the part is delicate and requires a higher maximum setting, it will be helpful to remove the
part from the bed as soon as possible after the completion of the build. Using the delay timer
feature will allow you to cause the build to end at a convenient time.
8.6 PARTS ARE UNUSUALLY WEAK OR CRUMBLY
•
Is the data file known to be without errors?
If the *.stl file is not near perfect you will have problems printing the part. Open the file in the
Z Corp. System Software and inspect it layer by layer to ensure there are no gaps and the
part does not overlap other parts.
•
Is there enough binder in the feed bottles?
When you start the build, a reminder box will pop up asking you to check if there is enough
binder in the feed bottles. If you plan to start a large build make sure binder bottles are full.
•
Are the parts dry?
If plaster parts are not yet dry they may seem weak or crumbly. Allow more time for the part
to dry, or put it in an oven for 30 minutes at 120-140F. For plaster parts, this may be done
even before depowdering.
8.7 PRINTER LOOKS LIKE IT IS PRINTING, BUT IS NOT LAYING DOWN
BINDER
As you begin printing, carefully watch the Z402C Printer to see if it is printing normally. It may
be that the print head are not properly seated in the carriage. This can cause a bad
connection with the temperature sensor and the print head will overheat. Prolonged periods of
attempting to print without binder flow will damage the print head. You will need to replace the
print
head.
