Just wondering if anyone is using iiwa with PRC?

I've been setting the 7th axis (E1), by using galapagos by minimizing the run time and it works fine.

but as the project gets more complicated, the longer it takes to calculate the optimal angle.

Currently my project have 5129 targets, having to provide and calculate a E1 for every target is proving to be too time consuming.

So i'm wondering if anyone have another solution?
