When I use Cura with the Pronterface UI it sometime just stops printing.
When it stops the printer just stops, the UI looks like it's still printing but nothing is moving in the printer, also, trying to control the printer from the UI does nothing.
It always stops early in the printing process, usually during the auto-leveling process or while printing the skirt, the latest it happened was during the first solid layer of a raft.
Usually closing the printing window and re-opening it solves the problem but not always, this never happened to me with the basic UI, I couldn't find any settings that makes the problem better or worse, it just happens randomly.
Anyone knows how to stop that from happening?
My printer is a Robo 3D R1+
After installing a screen on my printer I discovered Pronterface is sending a "Wait for user" G Code to the printer.
Because this changes the question too much and invalidates the existing answer I've asked a new question at What makes Pronterface wait for user?
