Thursday evening I was starting a print and I heard a sound you do not want to hear. The acrylic wheel cover broke. This is a piece that you can not fix by yourself. Even if I had the part I would have to remove the entire gantry to fix it and I am not going do that.
Well it turns out the Glowforge will still cut very nicely. The metal wheel does not touch the rail and so the gantry is able to move back-and-forth. I contacted glowforge and I have a replacement on the way.
If this happens to your machine you will still be able to use it until you get your replacement. I have a Glowforge pro and I am extremely meticulous about the hours. It had 253 hours.
I would be very interested to know how they tell you to replace it. I can’t see any way without removing the gantry. In no way saying it can’t be done, just don’t see a way.
