Thread: Weird Issue with a Fiber Laser Image

  1. #1

    Weird Issue with a Fiber Laser Image

    I usually test engrave on anodized aluminum blanks to make sure that I like what I see, and this is twice now, with 2 different images, that the bottom of the image bows upward. It throws off the whole thing. In addition, the top left lettering seems tilted inward just slightly. In my software, everything looks perfectly lined up, so this is really concerning.

    Any ideas at all?

    Looks like you need to adjust your quadrilaterals and pincushions-- F3 menu in EZcad-- it can be fun...

    Well, ‘aight, check this out, dawg. First of all, you throwin’ too many big words at me, and because I don’t understand them, I’m gonna take ’em as disrespect.




    Sorry, that's the first thing to come to mind (40 Year Old Virgin quote).

    Seriously though, you might as well have been speaking another language. I might have to call tech support because if I don't understand you, it's likely best for me not to mess with it.

    Kev, is there a reason it would be doing this? I've looked for what you've suggested to mess with, but I'm not finding a whole lot on what exactly I need to try and do.

    Yup. Country of origin. Should have been setup and adjusted prior to shipping. Part of the reason they are so cheap to buy.

    Just one one of the adjustments you’ll have to make. Kev has lead you to the right area. There are settings that control the skew and related settings. You’ll need to engrave tests and adjust until corrected.

    Whoa now Scott! This bad boy is a USA product.

    Bought it pre-owned though so maybe it got a little out of sorts in shipping, though it was packed like I saw with my Trotec. The image is only very slightly off on the outer edge, but when marking or engraving, I never even noticed it. It wasn't until I ran this test image on the outer limits of the lens that I noticed it.

    My bad, Kev mentioned EZCAD, and that’s a knock off Chinese product of quality software. You didn’t mention you weren’t running EZCAD, so I assumed he was accurate.

    What software is driving it?

    It's Tykma proprietary, but it's some variation of Ezcad. It's more user friendly as far as I can tell, though I can't find where those setting are that Kev is referencing.

    Oh WOW! You can see it big time when I trace out the largest possible marking/engraving area dimension. It bows in at the top and bottom and out at the sides. It's a good thing I'm only marking small items right now where you don't even notice it. Still, any walk-through on troubleshooting this? Kev, I hate to ask you to write a thesis, but any chance of a walk-through?

    This is two of the adjustment menus in EZcad. This first one is accessed via F3...
    params1.jpg
    The lower area is the quadrilateral adjustments ('quadrilateral' is just a fancy name for a shape with 4 sides, and I didn't know what it was 'til I looked it up )

    this is the 'basic' red light pointer adjustment--
    params2.jpg
    --the offset and 'scale' adjustments are so you can match the red light to the actual engraving. But the catch is, you have to get it to engrave correctly first!

    What I do: I print a 100mm outline on a piece of paper with my printer. I make the square in Corel and print from that. Then MEASURE it, you want it to be exactly 100mm.
    Place it on your engraving table. Now draw a 100mm square dead center in your program. Focus to the paper, this is important to keep everything accurate. Now red-light the drawn square onto the paper. Align the paper square to the red light square as best you can, I line up the bottom and left edge and start from there. Tape the paper down. This is where you'll find how far out your adjustments are. First, make some 'basic' adjustments, by changing 'scale x' and 'scale y' to get the actual size as close as possible to the paper's square. Offsetting is done later. Next is to compare your 4 sizes for curve and straightness. Me, I just fiddle with the numbers until I see something obviously change, and make note of it. It can take awhile but pretty soon you WILL get the shape corrected.

    finally- once you have the shape corrected, now you need to engrave the 100mm square onto something. It should pretty much match your red light results, but measure the actual engraving to be sure, and make tweaks until it's exactly 100mm both ways, and square...

    Once your satisfied, engrave a fresh square, then red light it. NOW is final tweak time, where you offset or scale the red light until it exactly traces your engraving...

    Once you're finished, you'll know that you can trust that your engraving will exactly match and fit to your red light, and you'll have square squares and round circles

    ---this is assuming of course, you have a similar way to adjust your Tykma program!

    "Some variation of EZCAD?". That's a frighting statement If it's made in the USA, then it's probably the software that EZCAD knocked off. If it's a knock off of EZCAD, then it's probably not as "Made in the USA" as you think

    Tkyma use ezcad software and a jcz control card ! The laser source is ipg (or maybe SPI) they have changed a few of the icons but that’s about it ! Nothing is really made in any country now! Most electronic components are made is Asia , the wire in it might have been mined in Australia, what does made in USA made actually mean ?

    I think tikma got source code and reworked the software. From viewing the YouTube videos, there are a number of features that are available in their version that isn't in the Chinese version. Yep, hopefully you can get to the adjustment menu....... BTW, my Ray fine was adjusted almost perfectly, I made slight adjustments but they were slight.

    Thanks Kev for the tutorial! I'm going to try and adjust it tonight.

    As to the EZCAD discussion, it's definitely core CAD with Tykma engineering built on top of it. There are quite a few user friendly features, at least that i can tell, that were added by Tykma for ease of use. The laser source for mine is SPI, though I think you might be able to get these with IPG sources.

    And John, I have no doubt that mine was configured correctly when purchased new, Tykma has extraordinary customer service. Mine must have gotten jostled around in shipping (second hand purchase), though like I said it was packed like my Trotec was when it was shipped.
