I got the Atoma 1200 this week and used it to flatten my norton 1 and 4k. I soaked my stones and lapped them under running water with only the weight of the hone as pressure. The process took awhile and afterwards I noticed a spot in the center of the Atoma. I'm most certain that the diamond grit was displaced. Was the 1200 too fine to be lapping my 1k? I tried my best to do figure eight motions and circles clockwise and counter. Check it out. After 30 mins of use.
