Grinders are one of the keys to exceptional espresso. Discuss them here.

Not yet, but if 0 doesn't cut it for a certain coffee I will. Already watched the videos and it doesn't look too hard. Just no reason to do it yet.

EDIT: just for funsies i adjusted the safety mechanism to allow me to go to -0.15ish and still no chirping sounds with the burr running. So I'll leave it there for now and if that still isn't fine enough I can recalibrate the zero point.

EDIT 2: I spoke too soon. I put a super light roast in and couldn't grind fine enough. Took off the lock and burr chirp was around -0.2. Got it recalibrated best I could and now burr chirp is just below 0 exactly where it hits the safety lock.

So I cleaned up my P64 latest version with factory zero settings and just found out that you must tighten the screws that places the hopper securely on a relatively equal torque or you miss alignment. I accidentally tightened the right screw a bit more forceful where the provided allen wrench start to bend than the left and that caused it to touch burrs and chirp at zero. Then I loosened the screws and retighten it to just tight with but not trying to bend the provided allen wrench on both resolved the issue.

I wish Option-O can provide a torque value on both screws on the hopper to ensure perfect alignment

had no idea about it! So how can we know then how much force we put on the same screw??


#2354: Post by theveterans »

I think a 1 to 2 N-m will do. What matters is the equal amount of torque to both screws. They should provide a clicking allen wrench to know that we have reached the optimum torque on the screws

i suppose if we tighten it till it naturally stops , we will be fine.


#2356: Post by theveterans »

Agreed. The medium resistance when it stops is the key. I was accidentally over tightening it due to my habit of assembling furnitures

Just a heads up to anyone waiting. Just got a shipping notification for my P64 order in the mid/late July batch.

Ordered black colour, mizen burrs and shipping to UK. Can't wait!

Is it a better practice to have to grinder running before pouring the beans in?

I've seen videos on Option-O's website and it shows them pouring in the beans first and then running the grinder. Doesn't this have a greater chance of the grinder seizing?

I don't think stalling is a problem with this grinder. I always pour the beans in first, and then start the grind. Never had a single stalling issue. So no worry's, and do whatever you prefer :D

I've done both and never had an issue with stalling. But keep in mind when adjusting the grind size , the grinder should be running.
