I get this message repeatedly after loading my files and slicing.What do I do? or what should I be doing?

Repetier

This (glGenBuffers ) is a function of OpenGL and it is missing. One reason coul dbe a very old openGL version. It looks like it is the host sending this message, so do you see the filament/models? What is the OpenGL version. You see it in the host log at startup. One solution is to not use VBOs in preferneces->3d settings. Then host will use only very old and slow methods. In that case you should not use filament visualization during print.
