I was running a print job with Cura and hit the cancel button.
The printer stopped in it’s track and then lost connection with Cura so I couldn’t move the X,Y, or Z axis. Also the temperature readings stopped showing on the Cura screen.
I tried clicking on the “Connect” button. It said “Connecting to Serial” (or something similar) then said “Closed”.
I’ve rebooted both the PC (Windows 7) running Cura and the Printer several times to no avail.
The printer is getting power. The extruder fan is running and there is LED light coming from inside the electronics box.
