It's happened a couple of times for me. Printing a design and about mid-way through, the printer stops and the Cura software is no longer running(Crashed).
Seems to me some longer print jobs where this occurs.
Below are two objects I was trying to print. After reprint, of the watch holder, it was successful.
The whistle, after two attempts still unsuccessful.
I have a Monoprice Maker Select Pro Ultimate/Wanhao D6 printer.
Using the Cura Windows 3.6.0 version.
