I recently saw a video on how to recover a print from a jam and was reminded of the question about recovering from a power failure I saw here a few weeks ago (Recovering from power loss with ABL possible?).
The YouTube video below gives some options which may work on our printers (he demoed on an Ender 3 which also runs Marlin) and thought I would share it. They seem to make sense, and I think they would work on our printers, but haven’t tried personally. It includes a section on how to resume without homing Z by disabling the software end stops and specifying a Z height manually (starts at 9:07).
Though I’d share it here in the hopes that it helps someone.
