Glowforge stuck on "Homing" - erratic movements


Im not sure where to go from here.

Current issue: Glowforge pro is unable to find its “home” upon turning on. (amber light)

I have tried moving the head of the glowforge under the camera and restarting several times. Each time it will slightly move (then amber light flashes) as if its finding center, and then erratically move away from center (amber light again turns on but now for longer). If I dont turn the glowforge off at this point it will erratically move the head (very quickly!) in random directions. I usually turn off the glowforge at this point since my old glowforge had done this in the past and slammed itself into the side of the bed. (Why does it allow the head to move so freaking fast when it hasnt yet found its center???)

This is a brand-new replacement unit from glowforge and about my third time using it. My last glowforge was sent back and replaced with a new one due to issues with the power supply and a focusing error.

Welp it looks like im back in the same place with my new unit, except now the glowforge seems to be suicidal.

Please help, i feel so unsure of using the glowforge… I am really the last person to say something like this, im typically super patient of technologies and their issues, but the glowforge genuinely scares me when it starts erratically moving around - potentially destroying itself!? I feel like i need to standby constantly with my finger on the off button just in case it decides to slam itself into the side of the bed…

Out of curiosity, is there any sunlight shining into the bed area? When I forget to close blinds near my machine, the camera has difficulty seeing the cutting head, causing all sorts of calibration weirdness.

Hmmm. Well, the only other things I can think of right now is checking that the cable to the camera is secure and didn’t come loose in shipping.

Also, when you shut off the machine, you are moving the laser head back to the rear, left side of the machine, before powering it back on, right?

I’m so sorry to hear your Glowforge is getting an amber light.

I extracted logs from your Glowforge and it looks like the light is because the Glowforge is too cold.

Your Glowforge Pro features a closed-loop liquid cooling system that uses the air from the room to remove heat. It’s boosted by a solid-state thermoelectric cooler that allows for heavier use at higher ambient temperatures than the Basic. It is designed to be used when the temperature next to your Glowforge is between 60 degrees Fahrenheit (16 Celsius) and 81 degrees Fahrenheit (27 Celsius). To check, put a room thermometer next to the right hand side of the Glowforge; it draws in air from underneath, on the right.

If you are still running into trouble, please let us know the following so that we can investigate further:

  1. A description of the things you tried and what happened

  2. If possible, place a thermometer next to your Glowforge on the right hand side and measure the temperature there; if not, estimate the room temperature

  3. The date and time (including time zone) when you had the problem

  4. Take a picture of the exhaust hose behind your Glowforge that includes the part where it connects to your Glowforge, and the part where it exits the room
