  1. The laser has nothing to do with the cut/line not joining. The offset being discussed is the blade offset. The tip of the blade is not the center so to correct for this an offset is needed which is the measurement from the rotational center of the blade to the tip. Not something you can easily measure so you just made adjustments in the software till the cuts are good. Cutting a square is an easy way to tell. If the corner is a true square the offset is good. If the corner is rounded or has kind of a Z shape to it, the offset is off and needs to be corrected. There's a thread on here some place with an image that shows what I just described as well as tells you which one is too much and which one is too little, I can never remember.

  2. For glasses that have a consistent angle they are actually a truncated cone and there are equations to figure out the surface shape. Attached is a spreadsheet I use to get the measurements of a template. I then divide the template into 4 sections and try to keep the design within one section. When you look at a glass, you are really only seeing about a 1/4 of it,maybe a 1/3 so if your design is bigger than that you have to rotate the glass to be able to see the entire image and can start to look unprofessional.

     

    There are also some web pages out there that will create the template for you, you just plug in the info. I never had much luck with them, and prefer doing my own templates anyway.

     

    Once you get the curve you then distort your image along the curve. I use Inkscape so I don't know how to do that in Flexi but someone should be able to chime in. *note, simply putting the text on the curve will not give you a true image reproduction, but will look pretty good in most cases and will at least make the text look straight.

  3. Don't know anything about VM, but with Signblazer and Inkscape there isn't much you can't do, just a matter of learning how to do it. Every design program has it's own way of doing things, some are easier to pick up than others. Inkscape is free and a pretty powerful tool. The only thing I've noticed that Inkscape doesn't do well is font manipulation, signblazer actually does a better job at that.


  4. Imperial vs metric is not the point. If you can't read 1/16 on a tape measure, you'd have the same problem reading 1/10 on a metric tape measure. It's not the not knowing how, that is the problem, it's the not being able to figure it out. If you can't figure out that the big line in the middle of the two numbers is the 1/2 mark or the slightly smaller line in between the 1/2 and the number is the 1/4 mark, than that is sad. Has nothing to do with being taught how to read a tape measure, it's basic 3rd grade math.


  5. In high school I worked for a local contractor and after the first week he gave me a small raise because I could read and understand a tape measure better than most all high school kids he had hired in the past. He made a comment to my Mom how impressed he was with my ability to measure and do basic math on the spot. So sad.


  6. What did you try in Inkscape? I just did an auto trace and the result was very reasonable for an auto trace, little clean up and it's be good to go. This is also a relative simple design, it would not be that difficult to do a manual trace/rebuild. Realize you may not of had time to dig into it, but when you do have time, this would be a pretty good image to learn on.
