@Mikejac use a screwdriver and fix it 😉

@RodneyB what??? @Zax is the only one who answers quickly, not only about his product. You are extremely unfair.
He gave you all the answers you need, in my opinion.

@Jonatas-Silva it isn't a laser problem,but a bug in the elekscam software. If you search in the forum, the same problem, together with the bypass, is well described.
But I suggest you to try another software, like t2laser, much more stable and full of functions

@RodneyB what are you doing is save a dxf file with a bitmap inside, not a vector. What you need, for cutting, is a pure vector image. Just to simplify, a vector image of a line is a sum of informations about the line, starting coordinates, ending ones, thickness...
a bitmap image of a line isn't a line, but dots.
Please forgive me for the extreme semplification.
If you want to cut a star, you must design it, for example, in Inkscape (or any other tool that manages vectors), as a sum of lines (possibly as a closed object), then export in dxf.
As @Zax wrote, you can also trace the actual image in t2laser, to obtain a vector (do not use sketch filled).

@Zax you answered me, not the guy with the problem 😉

@mawu as @Zax said, check the power supply, not only the cable by itself

@alex-berardi pazienza 😉, Zax lavora sempre con la massima rapidità possibile, credimi.

@christos93 maintain 2000 speed rate, and try 100 power (max, non min, of course). Based on results, decrease or increase power

@Zax yes, I know. I didn't understand the final scope of tmpx, tracing an image or drawing

@tmpx not so clear to me... If you need to import an image (bitmap) and then try to transpose it to vectors, this is correct. But if you need to design "vectors" from scratch, auto trace is useless
