Hello! I am so excited to get my Glowforge working to my expectations. So far, I haven’t had much luck with two major issues. 1) Camera won’t read the QR code and is out of focus; and 2) the laser just won’t make it all the way through the material I’m trying to cut. I read several similar threads and am not sure exactly what is causing my issue here. I have completely cleaned all the lenses, the mirror and the crumb tray. I used the provided lens tool and the Zeiss wipes (I got my Glowforge a little over a week ago). I unboxed and assembled/set up per all the instructions and was very excited to do my initial cuts. However, on each of my projects, I have had to sand the back of the pieces to get the edges to release since the laser didn’t cut all the way through.
I read about people doing double cuts and various other tricks, but sanding to preserve the piece and not burn the wood/draftboard made the most sense to me to do. The front side of the pieces is remarkable and the cuts are very crisp. However, there are only a few little dots and maybe a faint line or two when I turn the items over.
Also, I have had to select from the drop down what kind of PG material it is. I did try to adjust the settings to have the cut go a bit deeper on the PG Walnut. This was with the Walnut Hardwood sample I got in my kit. It is masked so I thought, perhaps the masking tape is causing a small increment of height that is causing it to not complete the cuts. This turned out not to be any different than my other cuts. I even used a Vernier to get my material height to assure that it was accurate. And after that, still having the same issues.
I made sure the crumb tray divots are clean. I cleaned it out. I cleaned the lens. The window on the side and the mirror. I just can’t figure out what else to do at this point.
I read about warpage so I have tried magnets, I have tried holding it down with the edge of another piece of material, etc… all the helpful things I read on here. But none of that seemed to help either. It’s SO close to cutting through but it just isn’t doing it.
Also, it is taking quite a bit of “breaks” to cool down. I’m in South Carolina but I operate this unit from my very comfortably air-conditioned home. We are usually around 74 degrees inside here and it has a small fan (toward the end of the hose) that blows the exhaust outdoors. So I’m not sure if that is normal or should also be a concern.
Can someone help me here or contact me and see if we can’t get this thing figured out? I’m so eager to use it and have it do what I assign it to on the first-pass.
Thank you so much!
