The program starts fine except the grid and boundry framework do not appear…opening an STL file dialog box indicates it was opened but nothing appears on the screen. Reloading the original software does not change this…have tried several times Can anyone help? Anycubic support does not seem to understand my questions and their answers make no sense. Have also downloaded and installed Photon Workshop on two computers which, after the initializing screen show up…does nothing at all. Can you help?
