Hello, may I ask which laser fixture you are using? The Lase-Array Blue/Green/Red fixtures do not have gobo wheels. As for the others, in order to have gobos appear in design mode, you have to go to the properties of the fixture, and set the Protocol to "design mode" or "DMX" in the Options Tab. (except for the XR300 laser, and the Wysiwyg Generic Laser -Beam). Note: when in this mode, then Live mode control of lasers will not work.
Thank 'you it works now, I just need to take my time and proceed step by step with my better friend (the manual... )
