Does anyone have any experience of connecting Cura to an E3P by Wifi, possibly by using a creality box? Best I can see, only the Creality mobile app can make a connection, although I have the printer and its IP address in my router settings. I would really like to be able to send a completed slice file to the printer over Wifi rather than have to sneakernet it into the next room every time. I'm sure I saw mention of a Cura plugin at some stage that might help, but I can't see anything in the Marketplace that might be relevant. I'll also raise this in a Creality forum or two, but hoped that someone here might have a solution. Any links or help very much appreciated! TIA.
