I am printing some medium size face shields. I am using a Rostock Max v2 with an HE280 hot end, Raspberry Pi 2, and Octoprint 1.4.0. I use Cura as my slicer, with the SeeMeCNC recommended profiles. When I first start the system I get a very good print. If I use the print button in Octoprint to print a second shield, it starts cleanly and then the print always fails about half-way through.
If I shut down the printer, the Pi, and Octoprint and restart them, I get another great print. Any ideas on fixing this?
