After ordering some PCBs involving fairly complex milling patterns from a Chinese supplier, I was given the production files and asked to verify that they are correct. However, I'm not sure what software I might use for this purpose, or even what format the data is in. I was originally given a RAR archive containing several sub-archives, that when extracted, produced the below file tree.
After opening the files in the root ok folder I discovered that many of them seemed to be gcode, but the coordinates seemed to be really large and the units seemed to not be in either mm or inches. I've linked the bl gcode file at https://drive.google.com/file/d/1iyDGTMyRQusyLc0Y1U8_9xC5eDlBLGwC/view?usp=sharing.
Any thoughts on what this file format is, and how I might verify its correctness?
