content: Howdy forum,I made this tool that will rotate your JLC components from IPC standard to "whatever they use". Simply create a library for yourself, enter the rotations for the footprints, and run your CPL file through it.https://root.aperture.science/jlc_rotations_fixer/Don't be mean and over-write someone else's parts library...

content: I'm not sure what you mean?The website loads properly for me, is it blocked where you are for some reason?I see you are a JLC representative! I love your service! If you were to use IPC standard rotations for your assembly though, no one would need to worry about wrong rotations again

content: Shit I added an entry into your rotations database, didn't realize it is centrally stored rather than stored in my cookies. Maybe consider the cookies option as right now someone could subtly change the existing rotations and fuck it up for everyone else

content: It is true, they are stored in a DB. I added library tags so people can have their own library and not touch another's, though.

content: Is this really needed (as in, does it make JLCPCB's life easier?). I only use my own custom libraries, and can probably define the parts to match the JLCPCB rotations, but seems that they fixed all my rotations manually anyway. In any case, is there a database of JLCPCB's default 0-degree rotation orientation per footprint?

content: Quote from: uer166 on May 14, 2020, 10:33:37 pmIn my last project with them, I tried to figure out their default 0 with little success. In fact, two different resistors from the same manufacturer (royal) that appeared to be in the same line (mfrs part number differing by only the value) seemed to have different default orientations. This was using the same footprint in my library so on my end, the default 0 is the the same.Also, I carefully rotated all my resistors so the value numbers were the same - consistent with the text printed on the board. (yes, you may call me AR - meh, I care about the details) But, the boards I got back didn't have consistent orientation of those parts, some were "0" and and some were "180". This was for the same part - same LCSC part number. To be clear, the board works fine.Another quirky aspect of this. They showed my placement and their "corrected" placement. After about 30 minutes of staring at them, I concluded that there were no corrections - I had gotten all my rotations right.The upshot of all this is JLCPCB gives us the tools to get our rotations correct, just don't expect it to be fully logical. And their techs will fix it if you don't get it right.

content: For the record, parts that are not polarised are not loaded in tape in a consistent orientation, so you will never get your resistor text all lined up one way.
