delay(100); Serial.println(">>"); for (i = 0; i<4000; i++) // Iterate for 4000 microsteps. { digitalWrite(steppin, LOW); // This LOW to HIGH change is what creates the digitalWrite(steppin, HIGH); // "Rising Edge" You can NOT trust any sort of power supply current measurement in order to measure the actual coil current at any point in time. This will prevent any power from flowing through the built-in voltage regulator, thus preventing it from ever heating up. Or like you said maybe a pull down resistor would do the trick also.Hope to see you at the next meeting!Dan. news

N.A. Clearly that was a pretty bad choice for the Easy Driver labels. If you solder .100 headers into the pins you want to use, it plugs into a standard breadboard. It was indeed, an "EasyDriver" to set up ;) PLEASE NOTE: some people have overlooked the extra (ground) pin on the easydriver board. https://www.sparkfun.com/products/retired/8368

Easy Driver Arduino

A ground pin has been added next to the STEP and DIR pins. There is now an official EggBot that you can purchase! The new Easy Driver v4 board now gives you access to the different stepping functions as well as various sleep methods which may help with your issue.

This allows for a 3-pin cable to your Arduino or whatever you use to drive the EasyDriver. Hey Dan, funny that we just met last week at the hackerspace meeting, and then I stumble onto your blog while looking for information about the EasyDriver board I just from Hi Robert,I've never heard of a stepper motor stalling at slow speeds. A3967 But fear not, the driver chip has a thermal cut out at 165 degrees C, so it will protect itself.

ProtoPICVideos 40,195 views 6:07 Stepper motor project for PIC - Duration: 19:48. Easy Driver Stepper Hi Daniel, how do you do? Hi Dan I like and used your tutorial and code as I am new to Arduino and stepper motors, I bought the ED4 board from Sparkfun connected as per your instructions have a peek at these guys I have not had any of these boards fabbed yet, as I'm confident in the design from the V2 boards. - Update: SparkFun is now selling these, and they work fine.

What’s the simplest way to do this? Control Stepper Motor With Pc This page is made available for those looking for datasheets and the simply curious. Q17) Does it matter which order I power things on? I have to add a 555 generator for the step input?

Easy Driver Stepper

Or you can write them on Projects page. http://www.canakit.com/easydriver-v3-stepper-motor-driver-rob-08368.html At the moment only 300rmp possible at a stepper with 200 steps because using delay() . Easy Driver Arduino Hi Dan,Can't say enough about your site here. Easydriver Stepper Motor Driver Datasheet June 5, 2011 at 3:06 PM Ross said...

So I took an EasyDriver and put a variable resistor across the 5V and GND pins and measured the temperature of the 5V regulator chip on the EasyDriver as I pulled http://freedesktopwallpapersite.com/easy-driver/easy-driver-pro-key.php There will be a new v4.4 soon which will fix this problem. (12/02/09) Version 4.3 has now been released to SparkFun - only difference being two mounting holes. (10/01/09) After a This makes sure that the maximum amount of current (as set by R16, the current set pot) is _always_ flowing through the coils of the stepper motor, even if it is I have since modded the completed boards to add the variable current limit. Big Easy Driver

You could also construct a simple 'carrier' board (on a proto board or some such) with female .100" headers for all for the EasyDriver pins.

See the table under question 14 below for some experimental data I took. Sparkfun Stepper Motor So the higher the M+ voltage, the hotter that regulator will get. All 8 of these measurements should be over 1MOhm.

It defaults to 8 step microstepping mode. (So if your motor is 200 full steps per revolution, you would get 1600 steps/rev using EasyDriver.) This setting can be easily overridden by

Jun 08, 2009 EasyDriver V2 This was the second attempt. This allows for a 3-pin cable to your Arduino or whatever you use to drive the EasyDriver. Connect a 4-wire stepper motor and a microcontroller and you’ve got precision motor control! Stepper Motor Controller By soldering SJ2 closed, you can switch the logic supply voltage for the EasyDriver from 5V to 3.3V.

Yes I'm getting that feeling trouble is I bought it from Sparkfun and I live in New Zealand but my findings do seem to suggest that the board is indeed duff. Ooops. A4) See above answer.
