Hi Brian,

I am running in mm mode, and I have 100 steps/mm, as on one rotation the screw is making 20 mm and I am running 200 steps/rev motors by 10 microsteppings Geko drivers.

Thank you,

Zoltan

Okay, we have had you check this but could you please post the graph that you are getting from the Driver test? I would like to see what your pulsing looks like :)

Thanks

I do not know how to get it?? I run the driver test and it seems very, very stable and smooth. The spikes are very small. How I can capture in a screen to post here?

There is a Print screen button on your keyboard (should be over the insert key). go into paint and press Ctrl V and that will paste the screen shot into paint so you can work on it.

Hope that helps and I think the small spikes are the problem

Hi Brian,

I captured three screens. The first is when I first run the driver test. The other two were captured when I run the driver test second time.
