Arduino mega ramps 1.4 pinout4/3/2024 ![]() 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. 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. RAMPS 1. For more details, please refer to the link below. This display is compatible with ramps 1.4 controllers and can be run with marlin and repiter firmwares. Using the rotary encoder on the board, you can move around in the device menu and access data. ![]() 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. The RAMPS 1.4 kit comes with the following components: Arduino Board Mega 2560 (generally a cheap knockoff) which is the blue board you see above. This full graphic Smart Controller contains a 128 x 64 dot matrix LCD display. So in my bumbling about trying to learn and figure out firmware I have hit a roadblock and cant get any further: I made it shorter for my needs ,however i want to make that motor rotate in one side and now it makes one step, changes rotation and run to another side. Otherwise if you use 1.3 or 1.4 it must be if you use a old ramps (1.0) then the pinout is: I have never used Arduino before but by reading tutorials etc, I have managed to get four. I am trying to control stepper motors, servos and an LCD panel without using MARLIN Firmware. I teach children to build themself 3D printers with ramps and know much about that board. I have a spare Arduino Mega 2560 with RAMPS 1.4 board and a Reprap Smart controller and LCD that came from a 3D printer. If that do not work are you sure it is a ramps 1.4? Try using Z-axis with digitalwrite, pinout is delayMicroseconds(pulseWidthMicros) // probably not needed Int millisbetweenSteps = 50 // milliseconds - or try 1000 for slower stepsĭelayMicroseconds(pulseWidthMicros) // this line is probably unnecessaryĭigitalWrite(ledPin, !digitalRead(ledPin)) Int pulseWidthMicros = 20 // microseconds this version uses delay() to manage timing on an Mega the onboard led will flash with each step testing a stepper motor with a Pololu DRV8825 driver board or equivalent The motor turns, slowly, one revolution CW then one revolution CCW and so on. NEMA 17 stepper and a DRV8825 driver in the Y axis. Here is a modified code from the Robin2's tutorial that has been tested, successfully, on my Mega with a Ramps 1.4 shield, a 200 step per rev. You have to use delay because it won´t work without it here is my code: //specify step pin, dir pin and steps per revolutionįor(int x = 0 x < stepsPerRevolution x++) I set my enviroment and I uploaded code, but my stepper motor hasn´t started movin´. I got 12V 30amps power supply and I changed pins for controling steppers to able to work with mega 2560. I tried stepper code on cnc shield with arduino uno and now I wanted to control stepper through arduino mega 2560 and ramps 1.4. I have stepper motors that I want to control, however I´ve ran into little problem.
