So, I have a LulzBot Mini 1. I followed the instructions on Cura to update the firmware. It failed during the upgrade with the error message “Firmware update failed due to an unknown error.”.
I tried it with the console open and I am getting the following error:
“Exception while trying to update firmware: <IapError(‘Timeout’,)>”
I have tried different versions of the .hex file. I went back to the version that came with Cura , all with the same error. I am still able to print with no problems but every time I launch Cure, it tells me it cannot determine the firmware version.
Any thoughts or suggestions are more than welcome.
