How could the dwell be too low if you put a hopper and a pot through it then it stopped? Surely if this was causing the marker not to cycle it wouldn't cycle at all? Not do a hopper/pot then stop?
Sounds like smartparts bull**** to me it never worked properly. When i had a look at the marker it would work for a few shots then turn off nothing to do with dwell. We tried different batterys brand new every time and it made no difference.
