Is there some trick to placing the advanced deep core mining drills. I tried to place one on a crack, but it only shows up as red. I kept moving it around trying to find a spot where it worked, but nothing.

Hello,

Thanks for the report, this should be fixed in 1.10.2 now.

ADCMD only shows up as red now 1.11.2 version, DCMD places normaly, factorio version 0.16.28

Hello,

I couldn't reproduce this bug, but it may be fixed in last version (1.11.3). Let me know.

Hello,

Ok I understand now ! The Advanced Deep Core Mining Drill will not work on Ore Patches that appear on depleted ore fields. This is what the normal Deep Core Mining Drill works for.

The ADCMD can only be placed on specific new deposits called Deep Core Crack that appear rarely in the world. They appear as a big dark blue square on the map and look like this :

You can use Resource Label mod that supports Deep Core Mining to see them more easly on the map :

They are only generated when you discover new land so if you have an existing save you could use the Delete Empty Chunk mod to discover them again :
