Had a prior thread on this, but it’s still doing it. I decided to record what’s happening - powers on, starts calibration, then resets completely like you’ve turned the power off for a moment. After that, it works just fine.
I happens after the machine has not been used for a while. First time I had in a few days yesterday, and again just now. FWIW it’s my main living space, room temp around 65ºF.
Hear the “clunk” when it shuts down (16s)? What’s interesting is the second time it calibrates, the head appears to move slightly with an accompanying click (~43s) - not as loud as the clunk. I wonder if the head is trying to move and it’s drawing too much power causing the reset? Note that movement occurs at the same time that the magic button lights up briefly.
Firmware updates to the machine are not that frequent, but updates to the control and analysis software behind the scenes at Glowforge are ongoing. If that’s what’s causing the flicker, it’s nothing to worry about.
I have not witnessed this happening on my machine.
The lights are powered by the 12 VDC supply. The 12 VDC is controlled by an output from the microcontroller. That output is currently set to switch on upon microprocessor reset.
That would lead me to believe the microprocessor is being reset.
There are several supervisory circuits that monitor voltage levels. If those voltage levels dip below an acceptable level, the supervisory circuits will reset the micro, which will flash the lights.
In other words: This looks like a problem with the device, not normal operation.
I’ve been having this happen on every power-on. After the reboot, it works fine. But I’m not sure why it’d need to boot twice. I had been thinking that it was firmware updates, but the last one was apparently about a month ago, and it’s happened to me the last three days when I turn my GF on in the morning.
My Pro does the same-powers off for a few seconds, then back on-but not every time I start up. My machine has worked pretty much flawlessly, so I’ve been working on the assumption that it’s doing what it should.
Mine also reboots after power on and it happens every single time. I don’t think its normal as others have said theirs does not do it. I have a case open already but so far support has only said they are investigating. Its been weeks, no real update.
