Trying to blend straight-line moves with an ethernet connection and Softmotion Lite

Hello All,


As it says, I am trying to blend multiple straight-line moves together on Softmotion lite, I'm also very new to labview. I have tried using the ExpressVI for blended moves to no success, as I get the error code -70037 or irrelevant attribute error when I tried to modify it for an ethernet stepper. I tried making my own, which is attached (I apologize in advance for the clutter, I haven't taken the time yet to clean up the front panel). While I have no errors while it is running, my motors do not do anything, and when I stop the VI I get the error -77005. For this I have attached a screenshot.


I was hoping to know:

1) Is it possible to blend moves at all with softmotion lite / ethernet control?

2) Is my code correct at all?


If it helps, I am running LabVIEW 2016 with Softmotion 2016, and my stepper driver is a SMD-7614. My stepper motors are running an 8-wire series connection.


I appreciate any help anyone can provide.

The differences between LabVIEW SoftMotion Module lite and the full version can be checked on the next link.


A notable difference is that you can't use coordinated motion, probably if you are trying to do several movements at the same time, could be the reason for your issue.

Hello Andgoro11,


Thank you for your response! Actually, someone else looked at my program, and I made an error when calling the resource for the axis. After fixing that error, my code does work, albeit it is a little clunky. I think with some refined improvement, it will work just fine!


Thanks again though!
