  1. I'm working on a university project and I've programmed the stepper motor on LabVIEW and am using the digilent motor adaptor but the signal leaving it doesn't seem to be right even though the labview control is correct in the signal that it's giving it. It can run up to 30rpm but then it stops and doesn't run. I have run out of ideas and think the error must be generated from the connections in the motor adaptor but I have no idea why as the connections seem simple enough. Has anyone done it before and have a ready made program for it. This is the program I am using at the moment. Main.vi
  2. Hello, I have a Nexys 4 DDR board and was looking to interface with motors for a project I am working on. I found the Pmod STEP: Stepper Motor Controller (SKU: 410-267) and had a couple of questions about it: 1) Is this Pmod compatible with my Nexys 4 DDR? 2) How many motors can this Pmod device drive. If more than one can be driven by this Pmod, can each motor be controlled individually or would the same signal be propagated to each motor attached to this Pmod. Thank you!
  3. Hello, I'm glad that this forum conentrates on technical problem solving . PROJECT: To control the stepper motor (x and y axis) through a website ,using ethernet shield and arduino uno. Ps :Esp8266 cannot be used. I'm following the attached code to which will take the Ip adress(line 29) and server address(line 26) and connect to the following website created by php and my sql(line 61). Created by Tom Igoe, based on work by Adrian McEwen. ISSUES FACED: The code must connect first and then it directs us to the website provided.But in my case it is
  4. Hello everyone, For a school project, my group is trying to make a 3D printer and we need to run 4 stepper motors (3 for motion and 1 for the extruder) using myRIO. Since we would need 4 drivers to run each motor, we are thinking of using a combination of these following adaptors. We are also wondering how could we control the heating element in the extruder using the myRIO controller? 2 of the Pmod Adapter for NI myRIO http://store.digilentinc.com/pmod-adapter-for-ni-myrio/ 4 of the Pmod STEP: Stepper Motor Driver (2 connecting to each Pmod Adaptor) http://st
  5. Hello! I have made an Instructable on how to use a stepper motor in unipolar mode. The code is specifically designed to run the stepper motor with a chipKIT board, but the general principle of how the stepper motor is run can be applied to any system board. You can check it out here. Thanks, James
  6. I have a question (not surprisingly) about the stepper motor that comes in the chipKIT Starter Kit (28BYJ48A). I know that I'm supposed to pulse the four lines to make the electromagnets "turn on" in such a way to make the motor turn one way or the other. I did so by driving various I/O pins on the chipKIT uC32 high and low and got it to rotate, but it seems I can only get it to rotate up to a maximum speed of ~12 revolutions/min, since any shorter delay than 3 ms between driving the magnets high/low seems to make the electromagnets shift around faster than the motor can keep up. My o
