It’s working now after two or three resets but worried this as a red flag.
I havn’t cut anything for about 3 weeks now (life is busy) but on calibrate stage head shook like that every 20ish seconds. Turned it off and on twice and gently shifted the head and gantry arm the third time and then the machine worked fine
Anyone else seen this? I want to make sure my machine is okay.
Yes. This is a pretty common side effect of the method of calibration. It’s trying to move the head under the camera so it can see the Glowforge logo, but it’s confused about what side of the bed it’s on so it keeps trying to drive left. Easiest workaround is to turn the machine off, gently and slowly move the head under the camera without touching the lens on the side and turn it back on.
You can sometimes make it less likely to occur by paying attention to ambient light hitting the Glowforge and confusing the camera (Windows, lights, etc.) Also material on the bed with head shaped holes in it can be confusing.
