Formlabs printers and accessories maintain diagnostic logs to provide detailed information about the machine’s functionality. Include these diagnostic logs with other relevant observations and details when contacting Formlabs Support or your authorized reseller to speed up resolution.

If your machine is connected to the internet and logging is enabled, it will automatically upload diagnostic logs on a regular basis. To enable logging on your machine:

• Form 2, Form 3, Form 3L, and Fuse 1 generation printers: Tap Settings > Connectivity > Dashboard Logging.
• Form 4 and Form 4L generation printers: Tap Settings > Analytics > Share print logs.
• Fuse Sift: Tap Settings > Connectivity > Dashboard Logging.
• Fuse Blast: Tap Settings > Connectivity > Device Logging.
