Custom motor control interface in Labview.

[ImSciStudent]

I am working with Labview 2012 on Windows 7.  I am designing a custom control for the movement of two Thor motors.  I would like to build a control that has four buttons (up, down, left right).  I have been able to control one motor to go right and the other motor to go up, but I cannot get the motors to move in the opposite direction with this custom control.  I have attached my program.  It includes a graph that plots the position of the motors as they move.  What are the options for moving in the opposite direction?

Hi IMSciStudent,

I would start by looking at this document which is a guide on LabVIEW and APT. Did the library of Active X calls from Thorlabs come with any documentation?

I have created a program that works.  It can move the motor forward and backward.  However, it always moves 0.02 mm, rather than the step size that I assign to it.  I am thinking that the the Event Structure doesn't give the motor enough time to move more than 0.02 mm before moving on to the next part.  How do you think I should handle this?  Attached is the program.

Hi ImSciStudent,

Can you create a simple program that does not include the event structure that we can use to isolate the issue? What is the default value for the step size?
