La Marzocco Swan
I'm puzzled how burr rotations can predict grind weight unless the number of beans fed into the burr at each rotation remains equal. This would seem to require a highly constant weight of beans in the hopper. It seems a long way away from single dosing territory

Drum roast profile on a fluid bed
Ramp/soak PID controllers are fairly inexpensive now, and using them on inlet temperature is a lot more robust in control terms than on bean (outlet) temperature, due to the faster feedback. The ramp/soak allows you to program separate ramp up and straight line times. You can also use several segmen...

Drum roast profile on a fluid bed
It does. I run very similar bean temp profiles on my Quest drum and P1 air roaster. For the drum, I keep my environmental temp at roughtly 500F throughout. On the P1, I ramp up the inlet air temperature from 300F to 475F in the first seven minutes, and keep it steady for the last three. The final

Option-O Lagom 01 Discussion
I did molykote the timing belt, as suggested. It's been a quieter (more than a little bit, but not dramatic) when the motor speeds up for the purge; and it stayed that way for the past few weeks. Don't know if it's permanent, or if the lube will need to be repeated

Mazzer Philos Comments
I would like to comment on alignment before this thread goes off the rails. Per our own Jake-G, who rebuilds grinders and can do extensive testing, as well as high end grinder builders like Titus, simple tests at the zero point, like using a marker test or the gap betwen chirp and lock are not good ...

Mazzer Philos Comments
The video in the last entry shows how the grind adjustment works. There is a lock at the zero marking (as well as the 145 marking), so it is impossible to make more than one turn on the adjustment wheel. I removed the collar to check for the chirp, and it was approximately at -3. After I changed

I don't have any. I'm not even sure they would fit in a standard 64mm mount

II haven't compared the Philos to the P64 or Zerno, since I have neither. This is a definite and huge missng piece in the review. It will be remedied when Dan and I send our review grinders to the next round of reviewers
