Hi,
A couple of days ago I had a print failure which was explained by a heater over-run issue.
Since then I have not been able to connect to the printer and although the board is being detected, the driver is not working and cannot be re-installed or updated.
The nozzle temperature can however be set using the printer lcd panel and the heat bed appears to work along with auto home.
Any ideas?
