    Had to put the project on hold for now. Still having a couple bugs...

    Actually, I misspoke. It's `M106 S1` instead of `S0`.

    Laser Engraving on Your Prusa MK3

    Hey, cool idea! I'm curios what use-case made you go the STL/Slic3r route and commend you for taking the initiative to create your own tool. As for the erratic laser ON behavior: make sure not to use M107 (turning the laser off), instead use M106 S0. The prusa firmware will spin the fan up for 800ms after it was stopped, which will turn the laser ON full blast for the same time too. You can disable this in the firmware (FAN_KICKSTART_TIME set to 0) but you'll have to compile it yourself and then keep doing it after each new firmware release.

    Hey Erik, thanks! Just sharing my solutions.As for the lasers, most of the ones labeled "module" will all have a controller - some have it mounted on the unit, some come with the controller as a separate part. I have both kind and it really is just a matter of cooling and the size of the PCBs that makes them different. Modules will have the control board, the ones I saw that come without are just actual laser diodes. As long as it says something like TTL or PWM in the posting you should be fine.Cheers!

    NEW Laribo updates! Thank you for all the feedback and suggestions. I recently updated my laser to a 5W module, and with that I took some time to make some upgrades.v1.1.0:- Sliders updated for more precise control, including typed entry- A recent firmware update by Prusa caused some unwanted behavior, where the fans would be blipped to 100% upon any new fan speed command - I implemented fixes so this wouldn't cause issues with lasers. Thankfully I found a solution that made it possible to solve this without changing the firmware.- Now you can adjust the maximum power intensity of the laser via a slider. This is useful if you have a powerful module but you only need a fraction of the power available to engrave without setting everything on fire.- Opacity applied to paths in the SVG will...

    NEW Laribo updates! Thank you for all the feedback and suggestions. I recently updated my laser to a 5W module, and with that I took some time to make some upgrades.v1.1.0:- Sliders updated for more precise control, including typed entry- A recent firmware update by Prusa caused some unwanted behavior, where the fans would be blipped to 100% upon any new fan speed command - I implemented fixes so this wouldn't cause issues with lasers. Thankfully I found a solution that made it possible to solve this without changing the firmware.- Now you can adjust the maximum power intensity of the laser via a slider. This is useful if you have a powerful module but you only need a fraction of the power available to engrave without setting everything on fire.- Opacity applied to paths in the SVG will translate to percentage of power! Now it's possible to engrave AND cut within a single file, or create the illusion of gradients! The intensity slider will also affect this in proportion with the opacity values (e.g. SVG path opacity of 50% will burn at 50% intensity if the slider is set to max; if it's set to 50%, the same path will be burnt at 25% intensity)- Opacity changes will be reflected in the Gcode preview as wellRelease and test pictures coming soon!
