Thank you Carlos! I tried cabling it correctly at the Ollimex board, but the screen does not come alive. No light in the screen. I think my Olimex board is broken so I have just ordered a new one. I will let you know if it works.

This could be it. Do you by any chance have a correct wiring diagram or picture of wiring? I have attached how mine is wired now. I wish you a great day

Would be perfect. Thank you very much.

Thank you for your answer nallath. So how do I update through the Ollimex board? The thing is I cannot update through the firmware through the two normal ways as it thinks it is an ultimaker 2+ Is there no way of doing it via the usb connection on the Ultimainboard 1548-I ? Or if I have to do it through the Ollimex board - how do I do this? Thank you in Advance

Dear Community, 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.
