That is a very interesting observation. I have not experienced something like this, but I think i'll get jebao slave doser soon (they are very cheap, and cost wise make sense instead of building individual peristaltic pump based system (that i use right now), i have a scope (thanks to @robottaway ) that i can use to test this sorta things.Here is an interesting bug I discovered with my jeabo doser setup. The last two dosers which were run continue to be powered at very low power after turning off. I noticed the green indicator light is slightly lit up barely visable unless it's pitch black. The unit also emits a hum very quietly which you can only hear when you are an inch away from it. What would cause this? Why only the last two stay lit up you can see on pic below. I am wondering if this is a PCA bug with frequency or something where since 100% works now 0 isn't 0. Could a Darlington transistor leak voltage? How shod I troubleshoot this?
Probably unrelated but the doser also doesn't run below 50% speed at stock 1500 frequency has anyone tried changing this to see if it will allow scaling to 0%
