Mini Rambo Not Responding

Hi all,

So I followed the instruction in flashing the mini-rambo and connected the wiring. However, the motors won’t respond. I tried connecting to Repetier host. It shows it is connected but commands won’t go through. I have tried with Estlcam as well, but nothing worked.

I have installed the driver for the card.

P.S everything time I’ve tried moving the motors with the LCD screen, the card resets whenever I tried to do any action on it.

Please help. I will try to figure it out on my own as well.


It is the Baud Rate, I have to set it to 250000. Solved my problem.

With just the LCD connected and no usb, what happens?
