Motors stutter, no movement
So I’ve finally managed to put together pretty much everything hardware-wise and wired up all the motors and stepsticks! (I’m using the RepRapWorld.com Ramps 1.4 DIY kit with 5 Stepsticks)
The connection is established, I can connect to the printer with Pronterface (Im using Sprinter firmware). The problem is that I can’t move any of the motors … When I try to move XYZ or E the motors don’t turn, but somehow they try to move in both directions at once, kickind and stuttering (no matter what the speed is set to).
I’ve searched all over the web for the past 2 days, I think I tried pretty much everything I could imagine:
- Adjusting the potentiometers of the stepsticks, tried all positions, no differnce whatsoever
- I thought that the wires are wired up the wrong way, because it sounded like the coils were fighting each other (I have these motors: [www.aliexpress.com]) so wiring should be as follows:
Blue:B- // Red: A+ // Green:A- // Yellow:B+ (I’ve also tried Blue/Green/Red/Yellow)
either way, same result; motors just stutter and don’t move
- The endstops are connected, tried reversing them (false/true) and canceling them out in the firmware, nothing
The funny thing is that sometimes, the motors started turning (quite fast), but the movement seemed random, can’t recreate it if I wanted to
Oh and one of my stepsticks seems to be broken, I didn’t fiddle with them at all, just didn’t get any signal from the motor connected to that stepstick, what could be wrong there?
I’m using an ATX Powersupply, with a 12V 15A output, I simply cut off the 4-pin connector (the 2 yellow and the 2 black wires) and screwed it into the screw terminals, also connected a fan to D10 because the Stepsticks were running quite hot during testing (although the have heatsinks) – not sure whether i connected the Power supply right, but since I can get the motors to at least react, I’m guessing yes.
I’m at a loss, tried everything i could find! Any suggestions?

Hello, I'm building my first RepRap. My setup at this point is: N1728D63 steppers (2A, 2.8V) RAMPS 1.4 Stepstick steppers. Sprinter firmware Pronterface A bit of background on the motor choice- previously, I had helped to build DIY CNC plasma cutter, and too weak steppers caused a lot of headache later, so I decided that it *should* be better that motors have more torque than required rather than being topped out. However, when I finished the wiring, motors acted strange- they vibrate around the same spot. I have double checked the calculations of steps/mm in firmware, tried to adjust the ...I've been trying to understand the Ardumoto behavior I'm seeing when I run the example sketch "Ardumoto_test_2". I've run with a couple motors, and they turn, but not the way I'd expect, and one of them hardly turns at all. I disconnected the motors just to figure out what the LEDs are telling me. So my first question is: Can I run using USB power if I don't have any motors connected? When I connect the arduino to external power I get the same results as below. To test it and figure out what it's doing, I'm not connecting any motors and just watching ...Recently I purchased 2 stepper motors from Adafruit. They are both the 12v, 350mA ID#324 motors. Before I first hooked the motors up to my Adafruit Motorshield, which I just completed, I checked the resistance of the coils. On one motor I got 33 ohms between the red and yellow wire and infinite resistance between the green and brown wires. On the other motor I got 32 ohms between the green and brown wires and infinite resistance between the red and yellow wires. When I run the motors one at a time off M1/M2 or M3/M4 on the motorshield, all ...Hi, Can anyone help trouble shoot my new Prusa build? I have a LMU8 Sanguinololu set up and have just powered up, checked all connections before powering, no problems. Checked how the Axis move and they are all free. I am using the Pronterface software. The problem I have is how the motors behave. The X axis works well but only in the + positive direction The Y axis works well but only in the + positive direction The Z axis tries but can't seem to move The extruder motor works well on both directions but the wrong way. The ...I bought the A4WD1-KT kit. They came with four GHM-14. Before I built the kit, I wanted to test out the motors, so I hooked them up to my power supply. When I turned it on, the motor instantly draws nearly 3 amps and doesn't move. This was the case with all four motors. Thinking it was something I did wrong, I put the motors to the side and bought some more motors. I got 4 PGHM-01 motors. When I tested them just like the GHM-14 motors, they worked fine. I also found 4 other motors I had purchased previously ...Hello RepRappers! Well, I'm writing this because I blew up 2 Stepsticks in a a row, and 1 more the next day... And I don't understand why that happened yet. I made mayself the RAMPS 1.25 board (the one with the 1K R for the LED). I attached some photos of it. Note that the pictures were taken before the Diode 1N4004 was desoldered, and the MFR500 fuse was installed. I'll tell my story.

I can power up to 2 motors only. How much voltage should I give to be able to power 4 together? Or do I HAVE should I split it into 10v for 2 motors each? I would perfer not to do this option Also these motors act in parallel when connected? Any suggestions in what I can do? I don't want to blindly blow the motors somehow. ThanksHi everyone. I am in the process of building my first (over-priced) QuadCopter. I do not understand the motor wiring. I understand motors 1 and 4 rotate their propellers clockwise, while motors 2 and 3 go anticlockwise. But I do not understand the wiring. My motors each havethree coloured wires (Red, Yellow and Black). The motor controllers each have three wires the same colour (blue). I have studied the construction photos and, looking carefully, I am confused as to which is which and what goes where. I have seen other kits where the motor and control wires are all the ...I bought three KL23H51-24-08B steppers from rrrf.org earlier this year and I discovered that the color codes were wildly different than what was listed in the docs. These motors work when wired as follows: A - Black B - Red C - Green D - White Yellow and Blue together Brown and Orange together Before I figured out the wiring was different the motors just sat there and buzzed - no motion. I have no idea why these color codes are different but I thought this might help someone else if it was not widely know already.Hello reprappers. I am building my first 3D-printer. It's a Prusa Mendel, and it's basically all assembled (except for the heated platform) However, now I'm hopelessly stuck with steppers that just judder. The electronics (Sanguinololu 1.3a) came with the ftdi pre-soldered, and I did the rest myself (another first) So it's all connected. 12V to the Sanguinololu.

Not much trouble getting things up and running except X, Y, and Z will only run in the positive direction. E works in both directions though. I left the MS1 pulldown resistors off in the build because I intend on running 4988's, but at the moment I have 4983's in there with MS1 jumped. Maybe this is my issue? Though I'm thinking that it is unlikely because E does work in both directions. I also tried pronsole and got the same results. move X 10 works, but move X -10 does not. No motor jiggle or anything. I've ...Hi, Im a newbie to Arduino and is trying to create a simple robot that can move and steer around. I'm using the Adafruit Motor Shield to simplify the control of motors, and with testing with servos and individual DC motors it works fine, however, when I try to fit it onto the Tracked Kit I got from Technobots UK, (listed below), the following things happens: http://www.technobots.co.uk/acatalog/Online_Catalogue_Tracked_Vehicle_Kits_434.html I tried to test it with the front motor connected to M1, and the back motor connected to M3. And tried to move both forwards for 2 seconds, then back for 2 seconds. However, only the back ...I cannabilized 2 dc motors from a cheap(3$) RC car, i am trying to control them using a ardumoto motor driver shield. Using a PWM value of 255 motors start spinning, but as i move the value lower to say 90 shield starts emitting a hissing sound and i can not set a speed lower than 40, it won't turn. I am using these motors to move the RC car. Right now i am giving short bursts of full power to make it move forward but it is not smooth. My questions are as follows, - That sound it is emitting, is ...Hi, I have an PhantomX Robot Turret running the Comm_EXT program. I would like to slow down the motors as i have a lot of weight on it. Is there a setting somewhere where i can set the motors to move slower? Currently I am doing a small move, then stop for a bit, small move again, stop for a bit.... many times. This is jerky, and i assume the wrong way to solve my problem. Does anyone know what do modify in Comm_EXT (or other files) to make the motors move slower? Thanks.Hello, I checked Invenscience web page and there is little info on their 12V Torxis motors which are also being sold here through Lynxmotion. What are the aditional two wires that connect to such motor. Except red, yellow and black that should go to controllers, there are aditional two. Do these two go to 12V source and red/yellow/black are just for signals from controllers such as SSC-32 ? Considering that SSC-32 is 6V output and Torxis motor is 12V, do those two aditional wires provide some kind of amplification for 3 wires from 6V SSC-32 controller or what ? Is it ...Hi everyone, i have problems with encoder steps : i want to get the smallest encoder steps possible, but motors only move reliably with steps gt= 20...why is that ? With encoder target values lt20 the motors will move but not every time (for example if i ask the motors to move 10 times by 5 encoder steps increments the result is the motors wil move only 5 or 6 times out of 10...). I thought i could use steps of 1 to 1440 units ? Am i missing something ? Is it a RobotC issue or maybe a hardware problem ...I have 2 motors like these, there is 3 wires on the motor, Black, White and yellow, and 2 blue on the end of the tachogenerator.
