i, I have the same concern as you. I am working on a galvo laser marking project. i want to put the galvo head in a CNC machine 5 axis (X, Y, Z, A, B) differ from the X, Y axis of the galvo. I manage to mark using the B rotary axis. But I still cannot manage for CNC A and XYZ axis. I am considering buying a DLC2 M4 3D card to have more possibilities. If you happen to have found a solution for your case, it may help me solve my problem.
