Hi Phill, thanks for open sourcing it, I am using this for one of my micro-positioning stage for my Lab.

While uploading Release/production/bom.csv to JLCPCB I hit a package mismatch, all 40 resistors on 0603 footprints are assigned 0805 LCSC parts. Every resistor part number in the BOM is from the Uniroyal 0805W8F series, but the PCB uses Resistor_SMD:R_0603_1608Metric and the BOM's own Footprint column says 0603. JLC's part matcher deselects every one of them with a package warning. R39 is the only resistor that passes, and that one genuinely is on an 0805 pad.

Two of them also carry the wrong value, which is how I noticed one C-number was serving two different values: R49, R51 — listed 1K, but C17530 is 0805W8F2701T5E is 2.7 k, R52 listed 4.7k, but C17414 is 0805W8F1002T5E is 10 k.

Hope this helps you.

Thanks for the update. That BOM was from a production run - the boards passed their DFM stage and were manufactured correctly so I must have somehow switched things. Sorry for the confusion and glad the fix wasn't very hard. I will leave this post up for others to see. If you want, you can zip up the correct BOM and attach it to your post so others can benefit from your work.
