Glad you stuck with it and got it working! It may be a decent idea to add OctoPi in the thread title so someone down the road with the same issue may find some relief.
One of these days you can teach me how to use a 3d printer… The wife will probably kick me out if I get one, so need to find a model big enough to live in.
EDIT: I feel like a dumdum for not properly searching - Just did a forum search on OctoPi and came up with: Dump978-fa.service timeout failures/restarts - #9 by mariusstrom
Our answer has been here all along. (Just to make this thread complete)
