  • Hi! Anybody has tried raster engraving with TinyG?

    I’m talking about something like this.

    I’m not sure how much work is done by the CAM and how much by the controller.
    I tried 3dpBurner-Image2Gcode and it works but it has a big drawback: any time it needs to change the laser intensity (basically M3 Sx command) it stops the cnc. The results it’s an ugly joggling of the machine… instead as you see in the video above, the movement should be continue, just the PWM has to change for each pixel.

    EDIT:
    I see I’m not alone 🙂

    But after almost three years the problem seems unsolved. I’m going to try the patyork’s fork.

    The issue you noted (114) is the most I have seen on this topic here.

    Many folks are doing laser on/off laser “machining”, but I understand the differences

    My swag would be that integrating S planning int X-Y(-Z) motion would be a challenge.
    Given that 3D printing is now the rage, I wonder, without any deep knowledge, if using a 3D printing stream with the ‘material feed rate’ parameter being used to modulate the laser would not be more effective, planning wise at least.
    My guess is there is a lot more focus on 3d ‘Gcode enhancements’

    Anyway, maybe someone else will stop by here but most often items that need significant FW rework get action over at Issues.

    OK, I see you had some success. good luck

    You might update your ‘Issues post’ with comments about your successful test.

    Could you post your re-compiled tinyG.bin file to a cloud drive?

    There is a user over on Ox Forum who might need it.
    Not everyone has a good build environment.

    Thanks

    Thanks.

    I’m not sure about your comment – did you build this in YOUR gitHub area?

    Gotcha
    So this binary has the S command mods as well as the SPWM-Coolant swap, correct?

    Agreed, this is your “laser mode” for S commands thread.
    I probably assumed your other thread “Alternative to PWM Spindle” was a necessary precursor to

    working for you, sort of.

    So for clarity, I’ll move back to that thread.

This machine is designed to make the laser engrave in wood and opaque plastic, having an Arduino and the GRBL as machine automation basis. The machine axis are just the X and Y axis, which move a laser with power 1w 445nm, and this article aims to provide everything you need to make, without waiving of mechanical and electronic knowledge. Hi all, just finished building my 3dp Burner by Villamany. Still waiting for the laser module though,so I thought I'd have a go at a pen attachment to see.
