Laser stuck calibrating

My laser has been getting stuck calibrating for the last 2 days. It goes from centering to homing then to offline. The laser keeps getting stuck in the center right under the camera.

I would try cleaning the top of the laser head and the camera, if it is dirty it will not calibrate correctly.

I cleaned everything and it’s still not working :persevere:

This sequence has often been the result of an unstable internet connection at the Glowforge, usually due to local interference. Use your phone as a hotspot for the Glowforge. If that resolves the issue, the problem is your home network. If it does not resolve the issue, report that on this support ticket and Support will assist you further.

Hi @Natali, I’m terribly sorry to hear about the trouble you are having with your printer going offline. I reviewed the logs from your printer and saw that your Glowforge was able to connect successfully to your network, but it may be having trouble maintaining a stable connection. When this is the case, you won’t need to go through Wi-Fi setup again, but you may see an “Offline” message.

The most common solution to Wi-Fi challenges is to restart all the devices involved in connecting to the internet.

  1. Turn off the computer, phone, or tablet that you’re using

  2. Turn off your Glowforge

  3. Unplug your modem

  4. Unplug your Wi-Fi access point

  5. Wait one minute, then plug everything back in and turn them back on

If that doesn’t work, we have two more suggestions that often make a big difference:

  1. Improve the signal path between your Glowforge and your Wi-Fi access point
    Wi-Fi signals need a clear path. Remove physical barriers, and move devices closer together:
    • Move your Wi-Fi access point up high and make sure it’s in an open space. Avoid locating your Wi-Fi access point on the ground, under a desk, in a cabinet, or in a corner where its signal can be blocked.
    • Relocate your Wi-Fi access point closer to your Glowforge
    • Move your Glowforge closer to your Wi-Fi access point
    • Install a Wi-Fi range extender closer to your Glowforge
    • Run an ethernet cable and install a second Wi-Fi access point next to your Glowforge

  2. Reduce electronic and Wi-Fi interference
    If your unit is near other devices that use Wi-Fi or a large number of electronics, temporarily turn off other electronics and devices in the area.

I also saw that you’ve been able to successfully finish the homing calibration and print since posting here, that’s great news! Could you please let me know if you are still having any trouble?
