I have a photon for a few months and just now managed to make supports to snap off like Velcro.
I am using prusa sli3er for supports ,then STL to default anycubic slicer for actual slicing, works like charm .
I had/have DWS XFAB, MOAI, XYZ Nobel 1.0A and the photon is my everyday go to machine if the print fits it. With proper dial in of the exposure parameters for each resin it works great for my tool shop prototyping prints. Also it works great with Bluecast resins for direct casting.
I am still eagerly waiting for my form3, this will be my first formlabs machine.
Also considering top down machine like milkshake or DIY
