Time for a field trip

Here are a few more photos. The first is taken after taking the top burr off showing retention using a low rpm (200-300):


Not seeing too much, but some larger bits are getting stuck and not fed into the burrs. Upping the RPM could fix this without messing with workflow too much. In videos of the Mini Z, Molar says you can use a brush inside to push the bits into the burrs, but this doesn't sound like a wise nor efficient solution to me.

Here's a photo of the upper burr carrier in my hand to give some scale to how large these burrs are:

That geometry is wild.

Those are gorgeous! Would just love to compare those to my 98mm SLM's but I think the distance is a liiiiiitle prohibitive.

Fairly positive it's the angle. The top edge of the blades on the bottom are overlapping the view of the retained coffee stuck inside them, making it look like there's more contact there.

Agreed - looked at some other pictures and think it's just the angle and post-processing done by my iPhone that make them look worn.

And out of stock.

Will do! Didn't know they were out of stock, I just assumed that they're mostly made to order. I've been trying out the max 400 rpm to speed up the workflow and can now grind a regular dose in around 10 sec with some minor grind adjustment. I can put together a video later this week if anyone's interested in seeing it in action.

A video would be great!
