Schedule doesn't work as it supposed to

[Omenas]

Hi all,
I connected my WE v2 and created Nutrient Export schedule, however instead of waves (pulses) it produces just a constant speed (interesting, that two pump run with slightly different power).
Anyone could help?

In your third screen shot Under pulse frequency ,you have selected 35 milliseconds. The time is hours\minutes\seconds\milliseconds.

Also it takes about an hour for that to run through the whole sequence for what I can tell. I use it 30 minutes after each feeding for an hour. My pulse frequency is set to 10 seconds.

I set to 350 ms (not 35) it's about 1/3 of second, I used such pulsing for waves on my Maxspect controller. If I increase it to 10 seconds it more like gyres, not waves.
Same with Square Wave pattern - the least wave duration I can set there is 2.5 seconds, what doesn't produce waves.
Danny what do you mean by 'takes about an hour for that to run through the whole sequence'? In description of this pattern is "Nutrient Export Mode generates waves to stir up detritus. Then a sudden and powerful forward movement is produced to flush debris", but my situation does not seems to be "sudden and powerful forward movement", it more like constant speed of one pump.

Can you share a screenshot of the flow pump definition? You've shared the schedules already but not the pumps. I would like to see both 350A and 350B.

Here it is

At 350ms the pump has fractions of a second to react. This will do two things. 1. You won't notice a change at all in pump function , It will appear to be a constant speed. 2. This will cause early pump failure due to the extreme nature of what you're asking the pump to do.

For it to get from the beginning of the pattern to the end takes about 1 hour. I watched it run on the app and at the tank.

I don't see a big difference in 400 ms and 350 ms, and as I said I used 400 ms (0.4 sec) on my max-spect controller (image above). Here is a video how pump did those two things which yor've mentioned with max-spect controller and I like it. I need help how to make pumps do exactly same with hydros we.

From looking at your video it is clear that the cycle you are getting is almost exactly 1 second, not 0.4 seconds. The Hydros times indicate the duration of a full cycle (so if you set it for 1 second it does 1/2 second on, 1/2 second off) It appears that the Maxspect time indicates a half cycle so 1 second means 1 second on, 1 second off. So you probably need to double your expected duration. Try a 1 second square wave. Then you will probably need to tune it up or down a litle to match the resonance of your tank.

I would also suggest you try it without Reverse Enabled. The pumps have to stop in the middle to switch directions. At a speed that high the gear shifting probably takes up most of the cycle.
