Hi there 
,
We support beveling for special production orders with assembly but not when ordering PCBs via our standard 0.8mm pool. However, many customers ordered M.2 cards using the pool and simply ran the PCB edge once over sanding paper for their hobby project.
When using edge connectors, please note that you always need to tell our software where to place the tab connecting the PCB to the rest of the production panel. For more details see: Custom Bridges and Frames
We will publish an in-depth guide in the near future.
Do you have further questions?
