So the glass lid on my ‘Pro’ has become loose and is not aligning so it’s not seating properly when closed.
I thought at first the glass had come out of a channel at the back but on closer inspection the glass is loose on one of the hinges. Is the glass just glued down?
I cannot see anything else that would secure it.
I’ve looked at both hinges and tightened them a little bit this has no effect on the actual glass.
Any help/advice would be much appreciated.
God bless,
Andrew.
Yes, just glued - and it’s happening much more on the more recent machines.
Plenty of discussion here if you search for threads with “lid” in the title…

Hi, I too am considering the ‘re-glue’… I’m reading through as much as I can both in this forum, a Facebook user group and YouTube videos!
For a machine that costs £7000+ I’ve been amazed that this issue evennhappens!
I’ve concluded so far that leaving my Pro in a room with sunlight has caused the glue to unstick!
I’m looking firstly for a piece of wood that I can put on the lid which will support heavy weights so that once I’ve applied the adhesive it can sit closed firmly overnight/24 hrs.
Here’s hoping!

It didn’t happen on my first machine, and I had it for many years. It happened quite quickly with my second. “They don’t make 'em like they used to…”

The official guidance from Glowforge is that your machine should not be kept in direct sun. I don’t think they’ve ever tied that to negative effects on the lid, more about the camera’s ability to determine where the head and gantry are with the harsh shadows cast by sunlight.
That said you may be onto something, I’ve never thought to try to cross reference “I’m having lid glue issue” and “I get direct sun”. If Glowforge has looked into it I don’t believe they’ve shared the result.

I’m looking for either some black out blinds for the room but then i’ll have to have the room light on or perhaps find a new location within the house… i’m thinking the living room although Mrs F might not be too happy!

If the sunlight can indeed soften the epoxy they use, just putting something over that section would suffice. A strip of paper taped along the back edge, for example. I’d make it wider than the glued area, as the glass would conduct heat from whole area. The lid is designed to block IR anyway, so it’s going to soak up IR from the sun pretty effectively.
I seem to recall someone said they just threw a towel over it.

i’m going to get something to stick it down with… has to be strong as the glass, although it isn’t, seems to be ‘warped’… going to take something really strong to do the job. Then i’lltry the towel trick before upsetting Mrs F and moving Garry in to the living room!

What about UV though?
I have one of the first Pro models and the glass has unglued 2 times. First was the front piece to lift the lid. Seeing as how this piece doesn’t need much pressure to lift the lid, I used one hour epoxy and it worked very well. Next unglueing was from the hinges in the back of the lid. There is a lot of pressure needed to lift the lid putting a lot more pressure in the hinge area. For this gluing I used some golf club shafting epoxy, this may be a bit harder to get. I got mine at a PGA superstore. There should be golfing supplies for do it yourselfers online. It takes 24 hours before you can use the glues areas. I used a piece of 2x4 lumber of the correct length to get even pressure on the glass and hinge area. I used heavy weights on the 2x4 to ensure good contact.
Hope this helps those who have had this problem.
