Hi Brian, Maybe my poor english is mistaking me but, from the site, here is the extract where drilling is defined: "# Our maximum drill size is 5.0 mm (197 mils) we can't drill large than 5.0 mm drill hole on your board, if your board have > 5.0 mm drill it will be replaced with 5.0 mm drill"
I may need to find another sensitively priced PCB company ? Thanks, M. --- In kicad-users@yahoogroups.com, Brian Sidebotham <brian.sidebot...@...> wrote: > > You have misunderstood their rules.
