    Default wood burning art help

    ive been burning analog abstracts into wood with great results, as long as i can slow my LFO's down to about 13 minutes per cycle, i can burn a design in 13 mins or sometimes a double pass in 26 mins and its done. i would like to do this with words and computer art files, any advice? i have quickshow, lsx, lasercam, ildsos, etherdream and fb4. do any of the tools at my disposal assist with something like this? would love to type something and then slow it way down! or is there any software great for this? i can do analog or ilda control

    ... check BeamConstruct - http://halaser.de/feature.php

    I've made some tests with one of the cheapest chinese galvo-scanner sets and an Easylase LC USB DAC - http://www.mylaserpage.de/DACs.html

    Here some videos, showing burning tests with paper or tiles:

    does beam construct allow you to draw one ilda frame over the course of 15 minutes? thats what i need help doing. i feel like I could probably do this easily in LSX i just dont know how as i havent started using the program yet. any advice?

    ... why especially ILDA frames?

    I'm laser-engraving all sorts of "vector drawings", imported in a bunch of different formats, with different lasers and varying moving/feeding systems - it depends mostly on the target application, not the other way round

    i have one ilda controlled laser and one analog (audio) controlled laser. doesnt have to be ilda frames but needs to be able to interface with my ilda laser

    ... to laser-engrave with an "ILDA-controller" you have to slow down the scanners moving speed and rise the pixel counts to get enough accuracy and time-per-pixel for results.

    With the EasyLase DAC I had to change the driver DLL for much higher pixel buffer per frame (50kpix instead of 3kpix) and slowing the scanner speed down to 10mm/s moving speed only for the first tests!

    My common engraving files have up to some millions of pixel positions, so there's a big efficiency/accuracy gap between standard ILDA frames and proper vector files for laser-engraving.

    The controlling of the laser is not such a problem - I'm controlling most of my lasers with TTL, regardless, if they are digital or analog modulated ... they only have to be capable for more than 100kHz repetition rates ...

    id love to be capable of this with etherdream or fb4. do i really need to get another dac for this?

    ... don't know -- could be, it's as easy as slow down the scanners moving speed to some ten mm/s and adjust the laser power accordingly ...

    so if i purchase the Easylase LC USB DAC, i can then use the beam construct software to talk to my ILDA controlled laser to make more precise woodburnings?

    ... my way was different - I had to test the usability of the cheapest XY-galvos available -- I've got some used chinese galvos with driver for 100 Euros, which are normally available new for 200 to 300 Euros

    I've then written a flow-plugin for BeamConstruct, to read HPGL-files and convert+output the lines as point coordinate sequences with predefined settings for speed and pointdensity/spacing. The EasyLase USB DAC will then output the X/Y-coordinates as analogue signals to the galvo-drivers.

    This is the choice, if you can write/program your own converter-plugins for your analogue drivers -- otherwise you have to find the best methode for your drivers or find a controller with a XY2/100 digital interface.

    The supported modes for analogue or digital controllers are listed here - http://halaser.de/compare.php
