I think I just solved the extruder problem!! As I was checking over the Sprinter file to see what I changed, I realized that I had changed: #define _AXIS_STEP_PER_UNIT {80, 80, 3200/1.25,700} To: #define _AXIS_STEP_PER_UNIT {80, 80, 3200/2272,7272} I then changed that code back to what it originally was, then re-uploaded it to the board. The extruder motor now seems to respond correctly to myby 3D-ME - RAMPS Electronics
@Waitaki I have plugged all the stepper motors in different ports, so I am pretty sure It's not any of my motors that are the problem. I did the same to my stepper drivers, so I doubt they're the problem, either. As for altering Sprinter, I changed: #define BAUDRATE 115200 To: #define BAUDRATE 250000 I commented out #define SD support I changed #define THERMISTORHEATER 1 To: #define THERMISTOby 3D-ME - RAMPS Electronics
Okay, well I inadvertently solved the problem with my extruder, but created a bunch of other problems! The extruder motor turned when I hit the "Extrude" button, but the motor its self actually felt pretty hot. (not sure why.) I've spent all afternoon fixing the other problems, and I'm now back to square one: the extruder is now not working, but everything else seems to be working.

I tried hitting "Extrude" button when it was cold and nothing happened, so I heated my hot end up and then I hit the "Extrude" button, but nothing happened that time either. I'm not sure if my hot end was at its target temp or not when I hit the button, so I might try that again. When I hit the "Extrude" button while the hot end is cool, I don't get any message, Pronterface just says "Extrudingby 3D-ME - RAMPS Electronics
Hello fellow reprappers, I am currently building my first reprap, and I'm having some problems. I'm using RAMPS 1.4 with an Iduino Mega 2560. Basically, I connected all the stepper motors, drivers, and boards together, and opened Pronterface. I can control the Z, X, Y motors, but when I try to get the extruder motor to move, nothing happens. I can't even hear any current going through the motorby 3D-ME - RAMPS Electronics
