I'm making educated guess here as I'm just getting into resin printing. I would say remove supports after washing but before curing. So you don't get the excess resin everywhere while removing supports if done before washing
I have a question that doesn't seem to be answered on any of the videos I've watched... DO YOU ONLY USE A CURING STATION IF YOU USE RESIN OR IS IT NECESSARY FOR SMALL FILAMENT PRINTS TOO?!! Hope I actually get an answer this time...
FDM (Fused Deposition Modeling) printers like the Ender 3 don't need washing and cure stations as those use a filament that is melted through a hot-end and cools/hardens naturally. Resin printers need washing and cure stations because resin is toxic and emits fumes that are harmful unless cleaned and cured. While it's debatable whether you should ventilate your FDM printer space, the fumes emitted are negligible and pose no real threat to you unless it's going 24/7. Hope this helps!
