2. Then, using the new DMX home value, calculate the maximum.
a. Set your pan value to the minimum DMX value (likely 0) and select a tilt value that
targets a point in your venue.
b. Increase your pan value 360° until the fixture is pointing at the same point again
and note this DMX value as your found pan value.
c. Note the minimum allowed DMX value for pan (likely 0) and the maximum allowed
DMX value for pan (likely 255 or 65535).
d. Calculate the User Min and Max Degree values:
•
min pan value = (360 ÷ (found pan - minimum pan)) * (minimum pan - pan
DMX home value)
•
max pan value = (360 ÷ (found pan - minimum pan)) * (maximum pan - pan
DMX home value)
3. Set the output of this calculation as your new user minimum and maximum.
4. Recalculate FPE (see
Calculating FPE (on page 498) ) and test for accuracy.
Tilt Range
If the tilt direction is correct, but the virtual fixture tilts further in either direction than the real
fixture, the fixture's physical tilt range or values may not match its profile.
Testing tilt range
1. Aim your fixture at a point on your stage. Press the “Flip” button. Does the fixture return
to the same point? If so, tilt is mapped correctly. If not, set the fixture's pan and tilt to
0°.
2. Pan the fixture in a circle. Does the fixture beam remain stationary, pointed straight
down? If so, tilt is mapped correctly. If not, follow the steps below to correct the tilt
range in the Fixture Profile Editor.
Correcting tilt range
First, find the correct DMX home value for tilt.
1. Set your tilt to 0°. Pan clockwise 360°, then counterclockwise 360°, and repeat.
2. Slowly increase or decrease your tilt value until the fixture spins with no wobble in the
beam during the sweep.
3. Set the raw DMX value as your tilt DMX home value in the Fixture Editor (on page 183) .
Then, using the new DMX home value, calculate the maximum.
1. Set your tilt to your new DMX home value.
2. Begin increasing tilt until the fixture head is approximately perpendicular to its base and
record this DMX value as your found tilt value.
3. Not ethe minimum allowed DMX value (likely 0) and the maximum allowed DMX value
(likely 255 or 65535) for tilt.
4. Calculate the user min and max degree values:
a. min tilt value = (90 ÷ (found tilt - tilt DMX home value)) * (minimum tilt - tilt DMX
home value)
b. max tilt value = (90 ÷ (found tilt - tilt DMX home value)) * (maximum tilt - tilt DMX
home value)
5. Set the output of this calculation as your new user minimum and maximum.
6. Recalculate FPE (see
Calculating FPE (on page 498) ) and test for accuracy.
Fixture Defects
If none of the troubleshooting or profile correction steps help, there may be an issue with the
fixture itself.
