Download GRBL for RAMPS 1.4 for free. I agree to receive these communications from SourceForge.net via the means indicated above. Alternatives to Modifying a RAMPS 1.4. If you have a RAMPS or other Arduino shield that can run at 24V. The Pololu A4988 stepper driver is rated to 35V max. Ramps 1.4 3D printer driver board for Arduino Mega controller. I myself did do some rendering, the comple kit together with Arduino Mega I. Contents • • • • • • Install the driver The first thing you need to do is that install the driver.This is very important.Many customers give us feedback that their arduino software are always come out to “Error”.Most of all,they have not installed the driver.This step is just for the starter.If you are a master of arduino,just ignore this step. If you have not use any arduino series board.You may not install the driver on your computer.Do not worry,here we go. Ati radeon x550 windows 7 driver download. There are two ways to install a driver. This post hopes to serve as a brief tutorial for RepRappers on how to upgrade the Sprinter firmware to Marlin on their RAMPS v1.4 Arduino Mega 2560 boards. It will show some specific changes required for the Prusa Mendel variant. With fundamental knowledge of your own unique build you could use this as an outline on upgrading the firmware for another model that uses RAMPS or even some other electronics. Hope it helps and I encourage you to leave feedback in the comments if this helped you out, if you have any questions or suggestions, or just to say hi. Download the following software before beginning the upgrade: • - consists of printcore, pronsole and pronterface, and a small collection of helpful scripts; put in your applications folder. • - open-source Arduino environment makes it easy to write code and upload it to the i/o board; put in your applications folder. • - a RepRap firmware mashup of and; the major advantage over Sprinter being Look Ahead (which keeps the prints as quick as possible); it is likely that if you purchased pre-assembled RAMPS electronics before 2012 it came preinstalled with Sprinter; download the ZIP file and decompress in a known folder. NOTE: This update was completed using Mac OSX 10.8 but the instructions should be comprehensive enough for someone to follow along in a Windows environment. If this is the first time running your printer it might be a good idea to check all of your hardware is operational. I have found (firmware) handy for testing everything quickly and easily. It will move your X, Y, Z, and E axes back and forth and heat the printbed and hot-end. WARNING: If you do not want your printer to heat up yet, disconnect the printbed and hot end from your board. Follow step 2 to upload the firmware to your Arduino Mega 2560. You must first edit your Marlin firmware code to match your hardware set up. In the Arduino IDE choose File>Open. Navigate to your Marlin folder you saved earlier and open Marlin.pde (or Marlin.ino). Along the top of the window you will see many different tabs, you will only need to edit the configuration.h and perhaps the configuration_adv.h (for advanced users) tabs. Go to the configuration.h tab. Here are the major changes you will need to make in order to get your RAMPS v1.4 Prusa Mendel working. First define your motherboard, look for #define MOTHERBOARD 7 and change the value to 33 for RAMPS 1.3 (don't worry, it works for v1.4 too) Next, choose your thermistors for your hot-end(s) and print bed; I have 100k thermistors for both so I have: #define TEMP_SENSOR_0 1 #define TEMP_SENSOR_1 0 #define TEMP_SENSOR_2 0 #define TEMP_SENSOR_BED 1 Under PID Settings I commented out #define PIDTEMP (add // before the line) to disable PID temp and enable bang-bang (To be honest, I am still not sure what this did, but it corrected my thermistors from reading about 20 degrees too high). I changed #define PID_dT ((16.0 * 8.0)/(F_CPU / 64.0 / 256.0)) to a value of 0.128. This was the value in Sprinter. I might try changing back in the next print to see what happens. Ramps 1.4 ManualFor my pre-configured hot-end I used Mendel Parts V9 on 12V settings for the hot-end I bought from MixShop.com. The mechanical endstops are defaulted to ON in this build of Marlin. To change the default to off change const bool X_ENDSTOPS_INVERTING = false to true for X, Y, and Z. To set the directions correctly I have the following settings, your settings may be different depending on your build. You can invert them easily by changing true/false. Driver Downloads For Windows 7#define INVERT_X_DIR false #define INVERT_Y_DIR false #define INVERT_Z_DIR true #define INVERT_E0_DIR false #define INVERT_E1_DIR false #define INVERT_E2_DIR false To calibrate your machine, you will adjust the values in #define DEFAULT_AXIS_STEPS_PER_UNIT I will have a following post showing the calibration of a Prusa Mendel. For now if you leave them as is it should be fine. My X and Y were pretty close and my Z was off quite a bit (probably because I have 5/16' not M8 threaded rods). Save your updates and you are ready to upgrade your Arduino firmware.
