Since I run my printer with Repetier Server with a Rasppi and a touchscreen mounted on the side table I don't really need the buttons on the LCD but it would be nice if it could at least display us this is a good exercise for me to learn how to customize Repetier. Additionally I was unsure if I need to configure the display.h AND the ui.h? In the documentation from Repetier I couldn't understand also how to figure out the pins which I would need for the LCD (RW, RS, Enable etc.) With the 1.0.0dev I was unable to compile the firmware, and got back the error: unknown board - LCD combination. Tried going through the pins.h and couldn't figure out the pins configuration I checked the configuration.h, noted that the FEATURE_CONTROLLER 24 was entered (I believe that is the correct LCD). Flashed the printer and no change in LCD, just two white lines. With the 0.92.9 I was able to compile the firmware (after selecting Analog Pin 1) with selecting the Zonestar P802 LCD. 1.0.0 version to try to figure out how to point the pins on the Ramps to the correct functions on the LCD display but with no luck. ![]() Viola, the thing lights up now, however, it displays only 2 white bars. I have been trying with both the Config Toll 0.92.9 as well as with the Dev. Directly hooking up the single cable from EXT1 from the LCD adapter did nothing of course.I learned that the Anet/Melzi/Zonestar have the physical power and GND pins switched, so I separated these two wires from the ribbon cable, cut them, and switched them. RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty of room for expansion. The Problem: the Anet A8 has the 5 Button LCD 2004 display. I have the RAMP Smart adapter for the LCD with the EXT 1 and EXT 1 connections. It consists of a RAMPS 1.4 shield, an Arduino Mega 2560 board (or a clone), and a max of five Pololu Stepper drivers. Setup: I have an Anet A8 and recently swapped out the Anet (or Melzi whatever you want to call it) for a Ramps 1.4 / Arduino MEGA and was able to configure everything using the Config. Print View Is there a schematic showing the pin numbers for the RAMPS 1.4 that correspond to the mega 2560 for arduino programming purposes I only know // For RAMPS 1. RAMPS 1.4 is probably the most widely used electronics for RepRap machines as of March 2014. These connectors have rated current of 3A.So in my bumbling about trying to learn and figure out firmware I have hit a roadblock and cant get any further: This example selects a RAMPS 1.4 board with the 12V power MOSFET connectors.
