Problem with shutter TSC001 and stepper TDC 001 controls

[Baronett]

Hi!

I am quite new in LabView. I am trying to control stepper motor PRM1/MZ8 with TDC001 and shutter SH1/M with TSC001 as the following: 

 Firstly, I need stepper motor to rotate for 5 degrees and then to open the shutter for a certain time and then close. After that the program should do all the above again and again. I use for opening and closing the shutter SC_Enable and SC_Disable methods. But in this case I can't control the on-time of shutter. Also, it seems that shutter doesn't always open completely. Please could you tell me, what other methods can I use?

Attach the current code.

Thanks in advance.

Hello!

I tried to open the VI but at first I could not, until I removed the text at the end of the name (not familiar with that language). I also want to let you know that is not recommended to use timed loops in a regular LabVIEW environment. This is for a Real Time system.

Also I am not able to run the VI due some controls missing. Can you let us know that software is required to run the VI?

Indeed, I forgot to mention that special software is required. Here http://www.thorlabs.de/software_pages/viewsoftwarepage.cfm?code=Motion_Control you can install software for shutter and stepper controls.

Hello Baronett,

As you may know this software uses ActiveX and there is almost no documentation about it. It seems that you will need to ask Thorlabs for more documentation about how to use the software.
