I purchased a 2nd hand mini and then purchased an LCD screen to control it independently.
The mini rambo didn’t have the outputs for the LCD screen so i purchased the updated mini rambo board and plugged it in as directed in the instructions.
I plugged it in and the LCD now flashes and clicks. I updates the firmware and restarted the printer but it is still doing the same thing.
I have swapped the p1 and p2 wires around but got nothing at all that way.
I’m a little tech savvy but not full nerd so basic tips would be great lol.
Any help would be great thank you.
