More to the point, you should close the breather valve on the resin cartridge when you’re not printing. That’s the only thing standing between a leaky bite valve and a machine flooded with resin. If they let you prime remotely, people wouldn’t close that valve. And then they’d have a potential warranty issue if a cartridge leaks. So if you follow the recommended procedure, there’s no way to remotely prime because you have to be in front of the printer to open the cap.
My printer is in my basement workshop. My CAD system is in my office upstairs. When I’m going to print something, I go downstairs and open the breather and prime the printer. Then I go back to my office, finish messing around with supports or whatever, and then fire off the print.
