USBSteppers Card!

[Boeing 747 Flyer]

Hiya all,

I am trying to set the OC USBSteppers Card up. I have two Bi-Polar motors connected to the card.

This is the script I'm using:

Var 0011, Link USB_STEPPER, Output 2, PosL 6, PosC 0, PosR 4, Type T

Var 0002, name Step3, Link USB_STEPPER, Output 3, PosL 6, PosC 0, PosR 4

Var 0001, name Step1, Link USB_STEPPER, Output 1, PosL 6, PosC 0, PosR 4

Var 0112, name Switch7, Link IOCARD_SW, Input 222 // EVAC Toggle Switch
{
 IF &Switch7 = 1
 {
  &Step1 = 180
  &Step3 = 180
 }
  ELSE
  {
   &Step1 = 255
   &Step3 = 255
  }
}

It's just a simple script that changes the speed of the motor based upon a switch press.

However, whilst an output is definitely provided to the Stepper Motors, I just get a jerky, unstable movement from the Stepper Motor.

The manual suggests this could be the motor itself, but after inspecting it AND trying a different motor I get the same results.

Also, after testing with a multimeter, it is clear that pins 3 and 4 on "block 1" of the 5 pin connectors do not have any sort of output going to them; which is obviously useless if trying to get a BiPolar motor to work!

If anyone has any ideas at all, please tell me what I've done wrong.

Cheers,

Jack

JACK,
Have you set up the iostepper.ini file?. Does the stepper self calibrate properly.That is when you power it up and run IOstepper.exe the motor should spin and pass the sensor once then stop at the sensor on the second pass,does it do that correctly?. If this is correct run the script they provide as an example in the manual,it works fine.

Hiya Les,

Could you please tell me where the IOStepper.ini file is? The only reference I can find to any sort of ini file in the manual is SIOC.ini, which I have already set up correctly.

Cheers,

Jack

Apparently there are two manuals

The one IWIK is referring to must be the manual which can be downloaded from the "shop" page where it says about halfway down

CARD CONFIGURATION
Card is configured with the file IOCStepper.ini

etc etc etc

The other manual which is amongst a whole page of manuals, does not I think mention the .ini file

Suppose you could try both versions

Regards

David

Edited for correction as there are two manuals

Hi Jack,
Just got up this morning and saw your message.
Here is the link, and is what i used to test my software. Im not sure exactly how one is supposed to run the stepper. Before the latest sioc v4.0 it had been said that this software was not needed as it was built in to Sioc but had read people had trouble getting the stepper to work. So any testing ive done and i used the example to drive the compass from Fsim was to run iostepper.exe after setting the .ini file and then run at the same time sioc.exe with your script.
Here is the link.

Hope thsi helps.

Thank you everyone!

After finding that second manual, I now have the Stepper motor running.

But that's all I can get it to do; literally, just keep turning clockwise forever until I turn it off. I can adjust the speed slightly through the tweaking of the various .ini files and SIOC, but none are slow enough for my needs.

I'm trying to use the Stepper motor as a Chronograph (ie synconise with the FS aircraft's clock). Are there any scripts for this like there is for Compass scripts?

If it helps, the motor has 24 Steps per 360 degree turn, and it's Bi-Polar. It is set up in accordance to the OC manual for Bi-Polar motor and works well, but as you can see I can't really control it.

I have absolutely zero experience with Stepper motors hence the post!

Are there any scripts for this like there is for Compass scripts?

Here you are courtesy of Carlos Lopez.

Edit Just ran through the code again and noticed that it is IOCP based, however, may give you a starter for ten. Looks daunting though

//
/ / In this Script I'm not using any timer mode to own the FS clock

/ / For this, the script rotates surrounding to the operation of offset 4 of the IOCP
/ / stores the data of the second FS clock.This is true, because I have seen

/ / mode, always our clock always displayed the exact data of the FS.
/ / For this, has been created a general variable which provides various States
/ / di visualization of the displays. Therefore, in Depending on the value of that variable
/ / will act as the script. These are the different States of the Time_Date_Year variable
//
/ / Time_Date_Year = 0
/ / Time_Date_Year = 1 Visualizo year
/ / Time_Date_Year = 2 Visualizo day and month
/ / Time_Date_Year = 3 Visualizo the Zulu time
/ / Time_Date_Year = 4 Visualizo minutes and Seconds
//
/ / To modify the date or time, be pondran in intermittent decimal points of each

/ / Thus the use of outputs we ourselves save of the Master and cabling towards different connectors
/ / of the Master. I have connected the two points the two-digit left decimals to
/ / an output displays (exit 4) and the other two the right to another output points 
/ / display (exit 5).
/ / Digits turn for each decimal point are:
/ / If we send a 9 to the 4 output ignited the two the two-digit left points.
/ / If we send a 7 exit 4 turns on the point the 2, which would be the hundreds digit.
/ / If we send a 9-5 exit ignited the two the two-digit right points.
//    
/ / Notice you turn on the point of the 2 digit for separate minutes, hours minutes
/ / the seconds or the day of month, depending on what that we are seeing.
//
/ / We have two buttons for the control of the lower displays. The active CHR button 
/ / timer and button ET Elapsed Time or time partial. 
//    
/ / CHR function. By clicking its button glows a led beside the push button that shows us that the 
/ / see in the display is the stopwatch. The second time that click we started. The third 
/ / stop it and so forth. If we want to put it to zero, click the RST button. The information

Jack,
Have you fitted an optical sensor and flag to your stepper. In case you dont know, you have to fit a little flag to the shaft of the stepper and this has to be adjusted to pass betweenan optical sensor to break a light source. Thsi tell the stepper where it is. When you first power up a stepper it will do one complete rev and then stop with the flag in the sensor. You have an input to stepper board from the sensor for each motor.
Have you done this ,its explained in the manual i directed you to. To test if your sensor is ok. Place your meter on the sensor input to the stepper bd and rotate the flag in and out of the sensor.Thew meter should go between 5v and ov as the beam is interrupted..
If your motor is continually turning then this sensor input is not working.
Let us know how you get on.
Les
P.s The motor should turn and stop as soon as you run IOsteoer.exe. No code has to be run.

Hi Les/David,

I do not have any sort of Optical sensor installed. I wsa under the impression Stepper Motors could be operated open-loop.

Is the optical sensor a DIY job or should it be purchased from somewhere? Are there any pictures available for my specific application?

Cheers,

Jack

READ THE FRIENDLY MANUAL

There is a picture of the sensor and a rs online part number 304-560
