Optimizing
The condition of the print heads directly affects the quality of printed models.
(Calibrating)
To maintain optimum printing, you should routinely test the print heads, and
Print Heads
calibrate them to the best working configuration possible by running the
Head Optimization wizard every 300 hours of printing.
During this procedure, you place a scale on the build tray and connect it to
the printer. Printing material (resin) is jetted from each head and its weight is
automatically recorded and the wizard determines how to optimize the print
heads.
If, during the optimization process, the wizard determines that a print head is
faulty—or that it is negatively affecting layer uniformity with the current head
configuration—the wizard instructs you to replace it. If this happens, you can
continue the wizard to replace the print head, or abort the wizard, to replace
the head at another time.
Run the Head Optimization wizard whenever the condition of print heads
is negatively affecting the quality of printed models, or if you suspect that
there is a problem with one or more of the print heads.
Note: Allow at least 40-50 minutes per mode f or performing this procedure
(not including time required for replacing faulty print heads). To accurately
test and calibrate print heads, they must be clean. If necessary, run the Head
Cleaning wizard before beginning this procedure.
