Well, they get a big +1 for service.
I gave them a call to see about the mod fix. I have the 1.5 inch mill and they did not make the retro fix for that one because people weren't having the same issues with it as the 2.0. So no luck there.
But he spent 15 minutes on the phone with me going over the mechanics of the mill and giving me some ideas to try. He indicated that it matters which direction you turn the adjustment knobs.
if you turn them clockwise (if facing the drive shaft side of the mill) the idle roller moved up and towards the drive roller, while counter clockwise, it moved down and toward the drive roller.
Clockwise means that the thumb screws are above the center line of the knob so if the idle roller tries to move away from the drive roller it hit s the thumb screw. Counter clockwise, on the other hand, means the center point of the knob is ABOVE the thumb screw and as the idle roller moves away from the drive roller it moves down as well, eluding the thumb screw and loosening enough to jam.
I don't know if this will be the answer or not but I will give it a try over the next few weeks and see what happens!
is it just me or is customer service among Homebrew related companies just a step or two above and beyond the norm?
