There is indeed a problem with the OSF format.
@formware, Elco, I’ve been invited to the VLare dev discord channel, I’ll pass on the details.
@Jimmygunz you can still use Formware to support and slice the supported STL in the VLare slicer. A PITA, but it works until such time as VLare sort out the issue.
BTW, OSF files generated by the VLare slicer work, so I don’t know what they’re doing differently
