When printing smaller objects I tend to print a few objects at once. It’s frustrating when a one or more objects fail but one or more are printing well. You have to either let the failed prints continue to harden resin onto the base and possibly partially cure resin above the failed section. Or you cancel the whole print even if one or more of the objects is turning out well.
So if the form1 was still connected to the computer or through an on board menu of some kind you had the ability to stop any objects that have failed while letting the rest finished that would be super great!
One suggestion for how this would work would be to have each object in the form file be given a unique name. That name could then be used via computer+Preform to tell the printer which object(s) to cancel or using the simple single button menu on the form1 to cycle through object names to cancel. On the Printer it self I would see this as an addition to the current cancel print option. Maybe something like long hold to get to the cancel menu. Then single short presses to cycle through names starting with “Cancel All” then each object name and a long hold on the name or “Cancel All” to do the canceling.
