Hi. My GF is generally working really well and I love it. However, I find that there are a few things that hint at a greater problem.
- The main gantry (I think that’s the right word) doesn’t rest as far back as I think it should. The unit I have is a replacement after my first one died and I remember that the first one slid all the way back when it returned to it’s resting position. This one sits an inch or so forward. This causes me to need to slide my material forward in order to get the best use out of it.
- When I cut a large rectangle and then flip it upside down to engrave the back, it doesn’t fit, even if the material was perfectly flat. It seems to have cut slightly skewed. I posted about this a while ago for reference: Not Square (skewed).
- Circles are not perfectly round. If I cut a circle the inside is not able to spin around freely, implying that it’s oblong. Even with the kerf of the laser, it gets stuck pretty soundly when turning it.
To better show the problems I made a couple of horribly produced videos with very bad sound. (Sorry, but you may need to turn up your volume to hear it.). It shows the gantry in the first one and specifically the circle issue well in the second. The rectangle problem does not come across, but I think that’s because the shapes I cut were too long and narrow. The other post is clear on that, though.
Anyway, I’d love to know if this is something that I can fix on my end. The precision of a laser cutter is what really attracted me to Glowforge and I would hate to have to live with it being off like this if I don’t have to.
