Welcome to the SeeMeCNC Community

Hello Team,

I could successfully assemble the Printer, while my LCD controller is not displaying any menus, It would just glow Blue and nothing much.

I tried re uploading the FW few times, sometimes the whole screen would blink and nothing much .

Can I have some suggestions or advice from the experts and people who already crossed the river.

Thanks in Advance.

The connectors of the LCD can be a bit confusing as you can get them mixed up in several ways. I would check them again.

To test if it is purely an LCD problem, try going forward int he manual and see if you can connect to the printer using your computer. Then we will know if it is an LCD problem or general firmware installation problem.

One thing that can happen is having the LCD ribbon cables upside-down on the board interfacing adaptor. Try flipping them around.

I could fix the issue with SeeMeCNC support and only seen the reply here now, thanks for the community support.

Yes, Flipping the Connectors on the Rambo Side fixed, the catch is to ensure the Notch in the top or the upward direction, Propably in the manual, its not visible clearly, Still the manual is great.

Also I would like to say, If you hear a mild click beep and turning the knob reducing the beep and the tower arms going crazy can be the findings to ensure you have swapped the Connectors.
