    Angry new "laserist" asks for help!

    hello all,
    I can not understand how I can distribute the points of a figure to allow the galvo to function properly. With "bmp2ild_v2" points overlap, and the figure is horrible. "pixel-to-point ratio" and "pixels to blank line" should I set?
    I attach the two files
    * thanks

    What scanners are you using and what angle and speed is this projected at?
    Although this seems as simple picture to us humans, the scanning system might feel different about it as there are quite a few small circular objects together with too many 90 degree precise corners and all are quire far from each other.

    you must understand that I am new in lasers and am trying to learn to use them.
    I have a 600mW laser with galvo from 30 kpps. I drew this and turned into ilda file. Use iShow with Spaghetti. Thanks for the help ....

    We all learn all the time ;-) so no worries..

    Presuming your scanning system is not Cambridge Technology and it is probably somewhere from China, it is unlikely it can actually do real 30k scanning. If this assumption is right then the picture is far too complicated for such scanning system. You can get it nicer, but you have to turn the scanning speed right down - so it will flicker a lot I guess.

    I bought this laser in Germany. I do not know if it comes from China. The colors are very beautiful. But now I want to try with ilda but I can not do anything because I'm an ass ...... I need just for fun at home, we'll see what I can do ....
    I will try to change the dac iShow because it sucks ........
    thanks and regards
