Hope you can help.
I have an Ultimaker 3 where I had to switch my main board. Bought a new Ultimainboard 1548-I and installed it with correct wiring. When I turned the machine on it came with ultimaker.com/ER01 error message which of what I can read is a head temp error of the Ultimaker 2/2+ ? This confused me a bit. - So next step I want to update the firmware on the ultimainboard. Problem is I cannot update it via internet or usb stick when the error message comes up. So I wanted to try updating it via USB cable, So I have detached the board from the back panel to access the USB cable connection point. In Cura there is no option to update the firmware on an Ultimaker 3 from the software (especially not because cura thinks its an ultimaker 2+).
I have downloaded the latest firmware today: "latest.tar.xs.sig" and "latest.tar.xs" - how can I update my board via USB cable connection? - Couldnt find anything online about it.
I really hope you can help me out - I wish all a great day.
