Optimizing (Calibrating) Print Heads
The condition of the print heads directly affects the quality of printed models. To
maintain optimum printing, you should routinely test the print heads, and calibrate
them to the best working configuration possible by running the Head
Optimization wizard every 300 hours of printing.
You also need to calibrate the print heads in these cases:
• after replacing Vero with Digital ABS or Agilus30 Model materials (and the
• after changing the type of Support material (SUP705/706)
• after replacing the Support material with cleaning fluid (and the reverse)
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 every 300 hours of printing or 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.
