This is the disappointing moment…
All of the lines that were previously vertical (that are now horizontal) are straight.
All of the lines that were previously horizontal (that are now vertical) are wavy.
That tells me there’s nothing “wrong” with the image. Rather there’s something wrong either with the Glowforge software, the Glowforge hardware, or my Glowforge hardware.
This really brings it all home. Horizontal lines, straight. Vertical lines? Wavy. Tom? Unhappy.
So… Did I have this problem all along you ask? Great question. As a matter of fact I asked myself the same thing. So I found my Founder’s Ruler. Guess what…
Vertical lines are wavy. I think all of the excitement of having the Glowforge ummm… laser-tinted my vision and made me think everything was perfect. Guess it’s not.
:sigh:
REALLY makes me wonder how everything I’ve done so far would have been better without the wavy y axis.
Yes. But just a request that I test on . I sent a pic of Test 1 as soon as it finished (a couple hours ago). They said they’re going to do the same test.
Wait a minute… Am I having dejavu or making things up, or did someone else have this problem too, a while ago. I swear I remember wavy glowforge ruler lines. But I also remember Berenstein Bears, so I’m not a great rememberer.
I shall go forth and search.
Edit:
Pretty sure this is what I was thinking of. But I don’t know how to do the fancy post people do, so ya just get a link
Confirmed. It’s so stable that as I watched and felt very carefully for any shaking or anything, I felt silly for even questioning it. It’s that stable.
Thanks for the test! I’m glad you’re not seeing the issue!
Look at that. Funny thing is, I’d already read that thread back in December, I guess, and completely forgot about it. I don’t see that Marion actually resolved his waviness. Not sure it bothered him very much. @marmak3261, care to chime in about that? Frankly, up until yesterday it hadn’t bothered me. But that was really the first time I’d done something that made the issue so obvious. It really shocked me when I saw it. And then when I showed my son, his first question was “Daddy, was this hand-drawn or something?” I smiled and said “No. I see it too, though. And I’ve already contacted Glowforge about it.”
Speaking of which, @Rita’s gotten back to me. Nothing much to say as of yet… just that she’s a couple more questions for me that she’ll ask sometime before Tuesday. I told 'er to go have a great weekend. She doesn’t need to deal with my crap right now!
Seriously though—that’s crazy! Seems like a weird alignment issue—it’s not like when the laser was going back and forth it just randomly continued the line a certain distance away from where it was in the previous swipe. Everything’s still connected so whatever it is the is incrementally shifting everything. It’s almost as if theres a ripple in your 's “digital trapping”.
Now I’m gonna have to run upstairs and double-check all of my creations and run a test or two.
Finally getting to this. Looks somewhat like the wavy lines I have experienced and which were on @macphee’s first BAMF Glowforge. Yours have a longer wavelength it appears to me in comparison of the rulers. I guess we’ll stay tuned for the response from the Mothership on these.
I have a lot of things that I’d like to do but am waiting on my forever unit that I hope doesn’t have the waves. It seems to be an artifact of construction from what I can recall. Perhaps how the rails are torqued.
I have seen similar wavy cuts in sheet material (MDF) recently on my CNC Router as well. Then, I spotted a set screw on the waste board. Apparently, a set screw had come lose and dropped onto the waste board. After fastening the screw I checked every machine screw fastener on every axis. The process wasn’t enjoyable, but everything seems to cut as intended. So, I am wondering if the hardware that connects to a rail needs tightening on the Glowforge too?
Welp! I’ve a screwdriver.
Wouldn’t it be great if Support gets back to me with a “Go give this screw a half-turn and you’ll be all set.”
Meanwhile I’m going to pretend I have no issue, but also be mindful of straight vertical lines. I have a couple of wedding gifts I need to make, but I can hold off until next weekend if it’ll make a difference. Otherwise, business as usual, I think.
It would be interesting to see a set square against the horizontal lines to see if they are exactly horizontal. I am wondering if the gantry is lagging on one side and then catching up. That would make the horizontals lean and so the verticals to get slightly closer together. Not sure it could make so much difference to the verticals without being completely off on the horizontals though.
I’m not a genius at this kind of thing. So I’m trying to figure out what I could use as a reference for that. I presume my material was dropped in at an imperfect angle (although it looks pretty damn close) so I don’t know what I’d measure against.
