What do you think of the cleaning times are they OK? Could it have something to do with that?
Th pellets are all one delivery so they are the same.
The angle of the screw (Auger) that feeds into the boiler is high it starts out at only 10 degr. then curves up to about 55 degr. where it falls into the down pipe.
I will test (measure ) pellets fall to find out if the feed is stable.
Also re-weigh the 6 mins amount.

Hi
I don't thik the problems is caused by the cleaning. It's only 4 sec each 10 min and the periodtime for the sving is about 20 min.
It seem that the swing is less with smaller gain on the oxygen control.
But one think that could be nice to see is haw big the swings are with oxygen controll set to "just showing".
Also to se how much the low and high pellets values is changed over the 20 min with oxygen control set to on. Note down the low and high values each 5 min or something like that.
I don't know special much about the flexiable screw you are using, but in mine the screw moves from side to side inside the pipe in some cycle, and give most when it's in the lower side.
The speed on the screw is about 8 revolutions per min it runs, but the movement from side to side is much slower.
But try to look on the values for about 20 min, and perhabs that give you some idea about what is going on.
