Yeah so this actually changed my grinder a lot. I got a k-max, before this my burrs were touching at 1.3 ( like 286 microns from burr lock, so for your grinder like 32,5). Now they are barely touching at 6 clicks and the burr can spin completly (360 degrees) for like 3 clicks before complete jammed forced burr lock. The difference in taste is gigantic. Thank you, you got me a new grinder! :))
Wow, that's pretty insane alignment! The closest I got was 8 clicks. I tried to get it lower and made it worse 😂. Got it to ~12 and haven't dared messed with it since 😅.
Jumping in late -- how about loosening all four set screws maybe a quarter-turn, tightening the cone burr (nudging the ring burr into alignment), then re-tightening the set screws? My Q2's burr is mounted the same way and is still well-aligned, but that's how I'd try realigning it if needed.
You could use little single wraps of tinfoil (just enough to wrap once each time so no overlapping kinks) to wrap the outer burr till it fits perfectly in the holder. Then check the alignment. That way you can see if the actual thredding is off. very unique style to your video that's professional, calm and composed :)
Great stuff. May I ask what is that fine o-ring contraption that you put under the adjustment ring at 4:15? Did you make it yourself and does it allow for finer adjustments?
I made it myself, cutting it out from a 1 gallon plastic water jug. And yes, it turns the JX-Pro into a stepless grinder. I will say though that the steps are already fine enough that most people might not find much benefit in going stepless.
Thanks for posting this video. I've done alignment on my 50mm flat burr electric grinders, where you use a dry erase marker to determine where to adjust the burr. How are you determining which of the 4 alignment set screws to adjust? Just by sound and hearing where it is rubbing?
Yeah, basically. It's very easy to listen and feel for when the burrs are touching, sometimes even where in general. But the adjustment process is very tedious, and any slight overcorrection can mean 10-20 minutes of tweaking.
I mostly use an electric grinder for espresso (64mm flat) but do break out the JX-Pro on occasion. It's very capable and actually quite fast. It generally takes me around 30-40 seconds to grind an 18g dose. As for settings, The Coffee Chronicler has a nice collection of starting points for different grinders: coffeechronicler.com/grind-size-chart/ For espresso, it's logged as 1.7-2 rotations with the JX-Pro. This is for the version with the grey dot (red dot is different).

Good news! This channel is UA-cam's JX-Pro totem of power.
Thank you very much for this detail video!

That seems worth a try, I'll check it out!
I am curious - do you guys already have some results with this method??

Hey, thanks for the input. Your idea sounds interesting. Might have to give it a try.
Thank you! I didn't even know those adjustment screws existed
Yeah, you're welcome. But as I mentioned, just be careful if you decide to mess with it. 1Zpresso does not recommend people do this 😅.
Very nice explanation!

@@davidmaurice1294 Ha, that's awesome! Just came across your video explaining this cool little tweak. Thank you for sharing it all and replying.
Thanks for all the helpful content! Which grind settings do you prefer for a med/dark roast for use with your Flair Pro 2?

1:00 rip i cant even take the burr ring out
Have you ever used the JX-Pro with 9Barista? Which setting?
