We have a massive amount of Edge Pro products so we figured it would be good to have a whole section on how to use the machine and what to use on it.

What DMT for flattening?

Sun Jun 01, 2014 7:54 am

Hi fellers,

what DMT should I use to flatten all those stones?

    Edge Pro 220 Grit Stone
    Edge Pro 400 Grit Stone
    Chosera 400 Grit Stone (light green)
    Chosera 1,000 Grit Stone (dark green)
    Chosera 3,000 Grit Stone (mauve)
    Chosera 5,000 Grit Stone (gray)
    Chosera 10,000 Grit Stone (light blue)

Can I use the Dia-Sharp Extra Coarse or is it to corse for some and to little corse for others?

Thanks a lot!

Super helpfull! Thanks a lot.

For documentation purposes: Better use different DMTs. Here is a copy of the ideal setup from the posted website:

400, 600, 800, 1K: Atoma 140
1,500, 2K: Atoma 400
3K, 5K: Atoma 600
8K and above: 1,200 Atoma

It's helpful to divide the topic into Flattening and Texturizing. If a stone of ANY grit is badly dished, something like the 140 Atoma is ideal - even a 15 or 30k stone.

But once flattened the surface texture of the stone should be appropriate for the task and the above scale is reasonable. I would extend the grit for the Atoma 140 down to the Nubatama 120. While you can flatten the 60 and 24 grit stones with the Atoma 140, the texture will be too smooth and you should 'rough up' the surface to something coarser with a piece of 24 grit Nubatama or a second 24 grit Nubatama.

Still waiting for my DMT to arrive to flatten my Shaptons (Atoma being out of stock), and I thought of using sand paper and not sure if this is ideal or a bad mistake?
I also have a ceramic flattening block bought at a woodworking hardware store for flattening water stones, which I've used on the std EP stones with reasonable effect.

GEEK <> Using the sandpaper is a bad idea as the potential for contamination is nearly an absolute. Particles of sand off the 50 paper will embed in the 100 stone then leaving errant scratches in your pattern.

{arbitrary grits for example purposes}

Thanks for the tip, you are correct, I had to use the DMT to repair.

I use a DMT coarse for 1000,600, and 400 grit. Extra coarse for 220,120. No problems so far.

I use a DMT coarse for 1k and up, and a DMT XC for anything under that.

I have only ever used DMT extra coarse and works fine for my stones..Just flatten a little more regularly.
