• Select Directory
• Check
• Format CSV
• Units mm
• Files One file per side
• With Insert Attribute set

Show

• All checked

Edit file for JLCPCB compliance

1. Modified Header

• PosX? become Mid X
• PosY? becomes Mid Y
• Rot becomes Rotation
• Side becomes Layer

Rename BOM.csv

Get rid of bottom cpl file

Upload

1. Gerbers, Check
