Q1: What kind of file Smart-Prototyping can accept?
A: Basically, Makerfabs only accept the production Gerber files, if customer has problems in generating Gerber files, customer can also send us the Eagle file(.brd), we can help to generate the related files.

Q2: How if I updated the wrong Gerber files?
A: Makerfabs don't check the functional& design problems, if your files are producible (meets all the spec and limits), we will produce the PCB as your design; if your files not producible, our engineers will contact you.

Note that if you want to update the files after the order placed, please make sure the order has not been "in production", that is, the PCB in normal production.
