![]() Make a pencil drawing of how everything is connected and post a copy of the drawing. Why not make life easier for yourself and start with a single motor like I suggested in Reply #1 It maintains the surface-mounted fuses and flush MOSFETS of the RAMPS 1.5. The following figure shows the pinout mapping to an Arduino Mega 2560: When used with a RAMPS board the 'Smart Adapter' provides an easy connection with the RAMPS. It replaces the original green power connector with a pair of screw terminals, adds a larger heatsink over the MOSFETS, and has a larger bed MOSFET. I think that code should work - so there must be a wiring problem The RAMPS 1.6 is the second RAMPS iteration released by BIQU/BIGTREETECH. fork of grbl-mega RAMPS 1.4 and modified for Makeblock Laserbot with Mega Pi board - GitHub - renebohne/grbl-laserbot: fork of grbl-mega RAMPS 1. 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. AccelStepper Zaxis(1, 46, 48) // pin 46 = step, pin 48 = directionĪccelStepper Xaxis(1, 54, 55) // pin 54 = step, pin 55 = directionĪccelStepper Yaxis(1, 60, 61) // pin 60 = step, pin 61 = directionĪccelStepper Zaxis(1, 46, 48) // pin 46 = step, pin 48 = direction 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. AccelStepper Yaxis(1, 60, 61) // pin 60 = step, pin 61 = direction AccelStepper Xaxis(1, 54, 55) // pin 54 = step, pin 55 = direction Please post your code properly using code tags so it is easy to read and easy to copy to an editor - like this #include The Ramps itself has no logic, nothing to interpret the signals coming from the Pi. #define TEMP_1_PIN 14 // ANALOG NUMBERING The Ramps is more or less an adapter board that maps the arduino pins to the drivers (and a few other peripherals). #define TEMP_0_PIN 13 // ANALOG NUMBERING ![]() Im not sure how though, can someone help me understand how as this is for a college project that I volunteered for but I'm really struggling! ![]() ![]() define SPINDLEENABLEDDR DDRG define SPINDLEENABLEPORT PORTG define SPINDLEENABLEBIT 5 // MEGA2560 Digital Pin 4 - Ramps 1. Also helpful for figuring out the pinout is the RAMPS connector mapping. I'm wanting to manipulate the code so that I can control 3 stepper motors at different speeds independently possibly using the tSpeed function of the stepper library? I want to use a Mega+RAMPS-1.4 or one of these, shield as I have them. Hi there, I have some code (below) that is basically to test that all motors/extruder/heated bed work on a 3d printer set-up. ![]()
