Operating & Maintaining the Connex500/350 3D Printer
Testing and
Calibrating the
UV Lamps
6–50
The effective UV radiation from the lamps used for curing models can
change over time. To ensure optimum curing of models during printing, a
pop‐up message reminds you to test the lamps and calibrate their effective
UV radiation after every 300 hours of printing. You do this by running the
UV Calibration Wizard.
To measure the UV radiation, you need:
•
TOL‐03003‐S (UV sensor and cable, supplied with the printer)
or—
•
a stand‐alone UV radiation meter, approved for use with the printer
The wizard compares the measured radiation to the recommended
radiation level for each of the lamps, at each printing mode—High Speed,
High Quality and Digital Material.
When calibrating the lamps, the wizard attempts to adjust the radiation
level, if necessary.
•
If the reading is within the acceptable range, the wizard continues to
the next phase.
•
If further adjustment is necessary, the current phase is repeated.
•
If the UV radiation is too low to be properly adjusted, the wizard
continues to the next phase, but the final wizard screen indicates that
the lamp's radiation for the printing mode is unacceptable.
Before testing and calibrating the UV lamps:
Make sure the glass lens on each of the UV lamps is clean. For easy
access, run the Head Cleaning Wizard, and use the special cleaning pad
supplied.
Make sure that the glass over the UV radiation sensor is clean.
To test and calibrate UV lamp radiation:
1. Start the UV Calibration Wizard from the Options menu (see figure 6‐27
on page 6‐25).
2. In the following screen, select
radiation level to the acceptable range.
