Calibration issue

Community Support
1

So I got my lovely :glowforge: today, got everything setup properly and even made a founders ruler. Pretty seamless! It is an amazing machine!

Got the girls to do a couple of drawings so we could test out the trace feature, and now all of a sudden the :glowforge: wont calibrate. “Sorry we are have trouble calibrating. Try turning your Glowforge off and on. If that doesn’t help, contact support@glowforge.com.”

Now before you say anything, I’ve already sent this in to support, but I was wondering if any of you have had any issues with calibration.

I have already rebooted it a few times and reset the gantry and laser head to no avail.

Yeah, I’ve seen it a couple of times today. They might be working on something behind the scenes again.

Does it move at all, or does it just sit there? Does the button change colors?

If it moves and then gives you the error, I would recommend turning off the Glowforge, moving the head directly under the camera, and turning it back on.

Yes it moves, and it even lines it self up right under the camera. After that its just hangs then displays the error.

I just tried what you suggested manually. When I turned it back on it did some micro adjustments which better lined itself up to the camera, then after a few minutes displayed that error again.

Hmmm looks like completely unplugging it for a few seconds did the trick. Interesting…

Off doesn’t always mean things are off. :slight_smile: Unplugging will actually allow all power to drain. So it’s a little different and sometimes necessary.

SO glad it’s working for you again!

I don’t know if it’s related at all, but starting yesterday my alignment was way off. Turning off/on helped, but after every few uses the camera would be as much as 1/4" off. I wasn’t sure if it was just my machine or an update issue. It does seem better today, but did happen again just one time.

Make sure you did not touch either camera lens or the golden laser window. If so, clean them with an appropriate wipe.

There is an accumulation of error in lid camera positioning through repeated operations. Somewhere is a statement from Dan regarding this, if I can recall correctly. I have not tested it as to how much accumulates through how many prints, but I have noted that I need to turn off totally every once and a while if I am trying to position with the camera on a small spot.

Correct. He suggested turning it off every day to prevent the positioning drift.

Thanks. “Drift” was the magic word, not accumulate.

A couple of things…

  1. Make sure you have the correct material depth set.
  2. As @marmak3261 said, power off every once in a while.
  3. Clean as per the documentation.

I had that happen to me once. Just once. And I bounced it and it was fine again.

BTW, there’s a question I’ve had for a while about what Dan said. It seems to imply that there’s a way to reboot that isn’t just power cycling. Or am I reading too much into that?

If there is I haven’t been able to figure it out. :slight_smile:
