Hopefully that fixed it for you. If not, here’s a useful list of things to check that can cause such errors:
- New thing to try - remove all materials and restart GF: Glow forge stuck on scanning
- Glowforge is Offline / Calibrating (support page)
- Lens inserted correctly?
- Turn the GF off, open the lid, turn it back on, and let it sit for a few minutes before closing the lid – if there’s a software update trying to download this will let it finish without interfering with the machine’s attempts to calibrate
- Recent exchange? Make sure correct GF is selected in the GFUI
- Look for any changes in the GF environment that might affect the wifi signal – one person had mounted a metal plate beside theirs, to attach their magnets to, and that was apparently enough to disrupt the wifi signal and throw the machine into eternal calibration…another piece of hardware could theoretically do the same (fan, printer, etc.).
- Try changing the GF’s wifi channel – too many devices maybe trying to use the same one.
- Sometimes cleaning the lenses seems to help – and also the Glowforge logo on the top of the print head, since the camera uses that for location purposes.
- Sometimes the ambient lighting can affect the camera’s ability to focus – could be too bright, or not bright enough.
- Check lid light cable clips Stuck on scanning during start up
- Don’t cover up the logo on the top of the print head
