PCB Builder Interprets gerber files UoM as Inches Instead of mm

Design Tools and Resources KiCad

I’m using KiCAD 8.0 and it outputs gerber files in mm and not inches. When I upload into PCB Builder, it show the correct dimensions, but UoM is set to inches, and I do not see a way to correct this.

It appears KiCAD uses mm internally, and is the format it outputs gerber files in.

Any suggestions?
TIA!

Thank you for your inquiry.

If you would like you can direct message me your zip files, I can take a look into this.

The ZIP file as provided didn’t upload for me.

There seems to be a lot of extra, unneeded files included with your ZIP archive.

When I selected what looked like only the necessary files, pictured below it successfully uploaded, and it indicated the unit of measure was millimeters.

Good to know. The only problem is this is a 4-layer board, and you only submitted two of the layers. What files will the zip file need for the two middle layers? Or can you tell me what files should be omitted (e.g. map, job, etc.)?

Thanks for the quick response!

These files successfully gave me a 4 layer board with millimeters for the unit of measure. The rest of the files are unneeded.

I should ask, is there a reason for the drill files assigned to different layers? If you’re not doing blind/buried vias NPTH and PTH should be all you need for drills.
