Since updating another of my machines to the latest OctoPrint, the RPI model B is not fast enough for USB printing. I plan to replace it with an RPI0 W2 but they are unobtainable at the moment, so I have reverted to uploading to SD.
OctoPrint seems to start by saving a local copy but that is confusing as it shouldn't be printed. It is so long since I used SD I can't remember if it has always done that.
If OctoPrint ever supports long file name writes it would even have the same name. How would that work?
