I have a Makerbot Replicator+. When I try to run a print that was generated with S3D, after about 15 minutes, the print stops and I get a heat sap error. When I print the same print using the makerbot software to generate g-code, There are no heat issues (just crappy prints!). There was a firmware update to the printer a couple months ago, and the issues seem to have started then. Any suggestions?
