    Laser Engraving on Your Prusa MK3

    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!

    Laser Engraving on Your Prusa MK3

    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!
