Hey there,
I'd like to build an MT32-pi hat, but I'm a bit nervous about finalizing order because two out of three vendors (Aisler and PCBway) I've tried don't seem to correctly recognize where to put holes/drills on the actual PCB.
JLCPCB apparently does, but since there doesn't seem to be a consistent behaviour in previews between the three service providers, plus Aisler told me the drill info is actually there BUT in a completely wrong position (see their reply with included picture --> https://twitter.com/AislerHQ/status/1602302545577263104) I'm not sure whether I would get the right, finished PCBs or not.
On the other hand, I see the gerber have been sitting on the Github repository for more than 2 years, so it seems unlikely a major issue like this would go unnoticed.
So... here's me, confused and asking for help.
