Make sure the red wire connects to + and the green wire connects to the signal (S) input.

Our endstop boards have a led to indicate when the switch is active, so we will need all 3 pinouts to connect them. The connections are located in the top right corner and the silk screen layer provides good descriptions +/- which is obvious and S for signal. The picture below shows connections with the correct color codes. The red wire is connects to 2B, blue goes to 2A, green to 1A and black connects to 1B.ĭo the same for E0 (extruder 1) and E1 (extruder 2) outputs. This is how the stepper motors are connected to the board. Notice that the Z-axis has 2 outputs on the RAMPS board.Īll the connections that we will make are based of this schematic overview. First insert the connectors of X, Y and Z axes. The bottom three ones are for the X, Y and Z axes and the other two are for the extruder stepper motors, named E0 and E1. There are 5 sections on the RAMPS 1.4 controller. Initially we will connect the stepper motor outputs to the board. We are now ready to connect the stepper motors, endstops, thermistors, heatbed and extruder hotends. The way that I remember it, is that the current adjusting 'screw' needs to be on the right, on the opposite side of the power inputs.

Notice the position of the stepper driver module. Now place the A4988 modules together with the LCD link part on the RAMPS board. The LCD 12864 board comes together with an attachment for the RAMPS 1.4 board. Next glue the heat sink on the chip of the modules. So, first place the jumpers on the RAMPS 1.4 board like this: If you search for RAMPS 1.4 on eBay you can find compete packages that include all of the mentioned parts, but they are still not assembled. Beside the 2 boards mentioned above, we will need 15 jumpers and 5 pieces of A4988 stepper driver module. To start with we will need to build the complete controller.

In this part we will describe how to connect it to various components of our printer. ZStepper.The brain of our 3D printer is the RAMPS 1.4 controller with Arduino MEGA 2560 board. YStepper.attachEnable(Y_ENABLE_PIN, 0, 0) // changed from xStepper XStepper.attachEnable(X_ENABLE_PIN, 0, 0) Here is the corrected code: // stepper sequence program by groundFungus aka c.goulding Totally my fault and I apologize to MicroBahner for doubting his library and wasting his time.

He found a typo in my code and once fixed the code works fine with the enable states all set to 0 as it should be. I had to mess with the attachEnable() functions a bit to make it work and don't know why. tSpeedSteps(8000) // steps /10Įlse if (step = 10) // pause at position ZStepper.attachEnable(Z_ENABLE_PIN, 0, 0) ZStepper.attach( Z_STEP_PIN, Z_DIR_PIN ) XStepper.attachEnable(Y_ENABLE_PIN, 0, 1) YStepper.attach( Y_STEP_PIN, Y_DIR_PIN ) XStepper.attachEnable(X_ENABLE_PIN, 0, 1) XStepper.attach( X_STEP_PIN, X_DIR_PIN ) Unsigned long timer = 0 // used to pause at a position. MoToStepper zStepper( STEPS_REVOLUTION, STEPDIR ) MoToStepper yStepper( STEPS_REVOLUTION, STEPDIR ) MoToStepper xStepper( STEPS_REVOLUTION, STEPDIR ) stepper sequence program by groundFungus aka c.gouldingĬonst unsigned int motorStepsPerRev = 200 Ĭonst unsigned int microstepMultiplier = 4 Ĭonst int STEPS_REVOLUTION = motorStepsPerRev * microstepMultiplier Ĭonst float adcCountsPerStep = 1023 / STEPS_REVOLUTION All of this is using non-blocking code so you can do other things while the sequence is running. The program moves the x stepper to position 800 and right back to 0 then the y stepper moves to position 1600 and right back to 0 then the x stepper moves to position 1000, pauses for 5 seconds and moves back to 0. Uses a Mega board with Ramps 1.4 shield, 3 steppers and using the MobaTools stepper library. Here is a tested (on real hardware) program showing one way to do what you say (if I understand what you want).
