first post here. got my glowforge (basic) two days ago (even before the proofgrade materials since i’m in the bay area). so far, it looks mostly great! been trying a couple of test cuts.
i seem to have a similar problem with the one described in Cuts not aligned to where I put them
here is the post-cut image at the center directly below the camera:
here is the post-cut image at the top right side of cutting area:
so, a couple of questions:
is this a cause for concern? i’ve used proofgrade draft board, made sure everything is flat, etc. but i consistently get a 1/4 to 3/8 offset (more on the X axis, less on the Y axis). will software be able to fix this? i’ve tried applying manual offsets, but that does not seem to be consistent across the bed (different corrections for different positions on the bed). i’m not sure how tracing would work well (which is how i first noticed the issue)
i noticed the image sharpness nearer the edges is pretty low (from my 2nd image). similar concern for large traces, too blurry to follow the traces. i also want to engrave on picture frames which are quite large and would be close to the edge of the bed. so a sharper image seems important for proper registration.
the single camera is super sensitive to the material thickness variations for areas further from the center. i guess using magnets to hold down large materials flat is important. perhaps there will be a 2 camera version in the future to eliminate the acute-angle errors.
there is a led laser spot (not round, more like capsule shaped) from the laser head to the material after pressing print and when the head goes to the starting position. anyone knows what that is for? something to do with determining the surface height of the material?
i had quite a few times where the head “crashes” into the left side (and never completes calibration), but i think that seems to be a common problem; just manually move the head to the center before powering on.
i’m glad to join the glowforge community. lots of super helpful people and posts here! definitely looking forward to cutting cool stuff
