Has this been happening for a while or did it start sometime in the last day or so? There appear to be network issues today. See the following posts. I just now started a print by selecting the drop down next to where it normally says “print plate” and choosing “export plate sliced file” which saves it as a 3MF file. Then copy that to a SD card and plug it into the printer. This was because in the slicer, I can go all the way up to send on the popup but it does not get to the printer.
