Today as we were trying to clean some filament off the print head of one of our Lulzbot Minis, metal tweezers made contact with the two red shielded red wires that go to the heater cartridge (or something in that vicinity). The printer was on and connected when this happened.
We believe the wires to the heater cartridge are still connected to the connector housing and were not damaged. However, now in Cura we are unable to connect to the printer. Cura does sense that there is a USB device, but returns the error message, “Can’t connect to printer.” The Power switch light comes on, but no fan. I also noticed on our other mini that I can see a small LED light shining in the space next to the USB connector when it is turned on. I don’t see one shining on the printer that is not working.
Serial number KT-PR0035NA-10940
Does the Lulzbot mini have a replaceable fuse? Any other ideas of what the problem might be?
