We’re excited to announce the latest release of PreForm 1.9.1! In this update, we’ve adjusted material files to improve prints across the board, giving your printer increased reliability. We have also addressed some reported issues with the 1.9.1 release that some of our users were experiencing. Read about our Release Notes for more information on updates to the software.
Ralph, shoot us a message so we can take a look. We have not had crashes with El Capitan here at the office, so it could be because of the update or something else.
