I have several errors preventing exporting the font, but I have pinpointed a particular error happening in the brackets—the auto hinter doesn’t like the tapering of horizontals (see screenshot). I hope I have the stem thicknesses in Font Info > Masteres entered correctly.
File also attached.
Check the weight axes values. In your
Regular master, change the
weight in Axes Coordinates to a non-zero number. A number of folk use the stem width, so in this example, I’d select 18. And then 120 for the
Bold master. In the Font Info > Exports tab, also adjust the
weight in the Axes Coordinates for the
Regular instance. You may want to adjust the others to match the new scale, too.
That should allow the autohinter to work properly. Hope that helps.
