Having problem with controlling two stepper motors individually

[Andre 8]

Hi. The problem is, if I want to deaccelerate one of them, while I want the other to go a bit further before i starts to deacc. In labview the whole program waits for a timer to run out, and then start execute the next step in the program. But i want to controll the pulses of the motors individually, without distrurbenses of the other.

Andre,

This seems like a job for multi-threading. You need to control each motor in a different thread, so they can be doing different things at different times without interacting.

In CVI you make use of the Multithreading library functions, and in Labview I assume you use some sort of multithreading VI (I don't use Labview so can't help much). Both environments will have a shipping example that will get you started.

Good luck
