Yesterday I received a bunch of bump messages for an hour or two while printing on my Pro. I did the things to address it, like covering the lid so there was no glare on the material. That kinda worked but still received a bunch of bump messages. Also a light came on that I didn’t know was there! just under the cutting head but it seems to me intermittent, and have not seen it since.
Today I was able to run a short print without any problems but when I ran the same print a second time the lines came out jagged, like there was a stutter in the machine.
I feel like these issues are connected and worry the servos are malfunctioning.
the rollers on all axis are free of debris. I tested a single line going up and then across and the stutter runs in both directions. I assumed if there was some debris I was not seeing this would isolate which direction to check.
Given your Glowforge skill (Bee Keeper), I suspect that you have checked all of the obvious things - debris in the belts/rails, belt tension, machine level, etc. The white light is something I have not seen, but it has been reported before. I suggest printing the Gift of Good Measure, getting your machine serial number, and reporting to Glowforge support.
I would have guessed a problem with the electronics driving the servos from your first post, and the fact it’s now stuck on focusing would support that from my point of view. I am not support, however, and that is the best path forward.
