The other day, I made a boneheaded mistake.
I turned on my Glowforge, and was immediately distracted. I left it alone overnight (not burning anything, just on), and returned to it the next morning.
Well, it apparently didn’t complete the homing sequence. The carriage was in the center Y position, and it was repeatedly banging the head against the left side.
I know the “official” position is that this will not cause any damage to the Glowforge, but I respectfully disagree.
(Preface: At least on my machine) There is not a physical stop for the head to hit against on the left side. Instead, the head circuit board hits up against ribbon cable and pushes it into the cable guide and ultimately against the X stepper motor.
As shown here:
While one or two (or twenty) times may not result in any failure, repeated bumping against that ribbon cable is likely to cause a fatigue crack in that cable.
You can see the creases that are already present on mine:
This is not a request for assistance, just a report of a potential issue.
