Is it still true that Open Mode disables resin dispensing? I thought I saw a post from FormLabs that you could fill an empty cartridge with resin and keep using it. Though of course the Form2 will think it’s the same as the cartridge’s original type, so that would have to match.
To be really useful, Open Mode shouldn’t disable the capabilities (resin filling, heating) since they’re useful for experimenting with other resins. If anything, Open Mode should enable more options than standard resins, so you can ‘tune’ the printer to work with resins that don’t match the standard settings.
