In principle, the origin should be at lower-left corner of the print platform (origin: ), or at up-right corner (origin: ). The parameters are different for different machinery. Mistakes are often made in the above two parameters. If it is connected to the NC (normally closed), true should be changed to false. That is to say, mechanical end stop should connect to the NO (normally open) contactor. If the configuration is true, the end stop outputs 1 in default condition, and outputs 0 when triggered. The three parameters are set for the end stops of three axes. If you use other 3D Printer, such as printer to make Chocolates, 45℃ is appropriate, so that the parameter configured to a lower value(such as 40℃). This parameter is set to avoid the potential risks when the extruder operates before reaching the rated temperature. You must modify depending on the temperature sensor you use. The printer can’t operate normally, even has potential risk (damage the device and even worse). They are the critical parameter to check if the sensor read temperature correctly. The two parameters are set for the type of temperature sensor respectively. For other board, you can refer to the annotation on the board. The parameter of mega should be 33(single- nozzle) or 34 (dual-nozzle). 3D Printer has many types of main board, and the setting of IOs is different, therefore, the parameter has to correspond to the type of your board, or it can’t operate normally. The last three are frequently used for 3D Printer. Note: a successful communication can be realized only when the Baud rate of upper computer is identical with that of Firmware.

This parameter is for the baud rate of serial port. The parameters that need setting are as below, for those not mentioned just leave them as default. Mega 2560 can’t be put in use directly without uploading firmware.ģ. Mega 2560 is the CPU of a 3d printer, manipulating the whole process of printing. Set the communication port (the COM port for mega) and the Baud rate. some frequent errors are: a wrong select of board type and serial port.Ģ. If the uploading is unsuccessful, read the error report on IDE, figure out the problem, and then try again. If not, click to upload.Ĥ.During the process of uploading, the 3 LEDs corresponding to TX, RX and L on mega board will blink, if the blink stops, the uploading is done.Īfter the uploading, you can go on with the next step. (Picture below)Ģ.Select the serial port: Tools > Serial Port, the serial port for mega is usually the last one.ģ.Click to check if there is any mistake. Then choose the type of board: Tools > Board > Arduino Mega 2560 or Mega ADK.

You are advised to connect all the components before testing.Īs Ramps1.4 is just the shield board of Mega2560, the firmware must be burned into Mega2560.ġ.Before uploading, driver should be installed for windows. Like other electronics, the inverse connection of power supply can cause irreparable damage to the board (4988 included).

The combination of Ramps1.4+MEGA2560+A4988/DRV8825 is becoming a mainstream of DIY 3D printer control board.ġ.

Owning to its stability in operation and great compatibility with most 3Dprinter (all reprap-model such as pursa i2 and i3). Ramps can only work when connected to its mother board Mega 25/DRV8825.

Ramps is short for reprap Arduino mega pololu shield, it is mainly designed for the purpose of using pololu stepper driven board (similar to 4988 driven board).
