Have just gone to use my autotrickler after having it sit idle for several months and found that the main powder dispense tube won't turn freely. The stepper motor is fine, it's jut the tube. It's always been emptied after use and never lubricated. The nylon(or whatever plastic it is) bearing surfaces of the tube appear ok but do have some faint visual marks.
Anyone else had any similar issues or have any suggestions
Cheers
