MediumRoastSteam Not sure if it makes any difference, or whether it’s better or worse than box standard wdt tool.
The few times I tried mine (before my Lelit was sold/shipped) I noticed more (not less) channeling.
But then I followed the vendor’s directions and used 12 needles (4 short and 8 long) and spun it (also as per the manufacturer’s video) 20 fast turns. When I next try it (after my Decent arrives) I will use 6 needles (2 short and 4 long) and spin it say 6 slower times. I think that there was just too much grounds movement.
How is yours set up? How many short and long needles?
I noticed that you did about 6 slow turns.
