Hi,

here is a short guide to create a MapProxy grid from a WMTS capabilities.

We start with a custom grid

grids:
  view1: # you can choose any name here
    origin: 'nw' # as defined by WMTS

>         <ows:LowerCorner>120000 5900000</ows:LowerCorner>
>         <ows:UpperCorner>1000000 6500000</ows:UpperCorner>
>       </ows:BoundingBox>

    bbox: [120000, 5900000, 1000000, 6500000]


>       <ows:SupportedCRS>urn:ogc:def:crs:EPSG::25832</ows:SupportedCRS>


   srs: 'EPSG:25832'

Here we have a scale. I'll spare you the rant and just point to yesterdays mail from Frank :)

You need to divide the scale denominator by 0.28/1000, which gives 1638.4.
You can do that with mapproxy-util scales

% mapproxy-util scales --as-res-conf 5851428.57142857 2925714.28571429
    res: [
         #  res            level     scale @90.7 DPI
         1638.4000000000, #  0     5851428.57142857
          819.2000000000, #  1     2925714.28571429
    ]


grids:
  view1: # you can choose any name here
    origin: 'nw' # as defined by WMTS
    bbox: [120000, 5900000, 1000000, 6500000]
    srs: 'EPSG:25832'
    res: [1638.4, 819.2, # and for all other levels]

  

Regards,
Oliver
