Is there a way to laser engrave using g-code?

Is there a way to laser engrave using g-code?

It would be great if G01, G02, and G03, linear and circular interpolation moves would turn the laser on and G00 (rapid) moves would turn the laser off.

Is this a good question?

You sure can! Add a L1-100 command to any G1 line and it will power the laser at that given power level (1%-100%) while executing the coordinates. Example:

G1 X100 Y0 L50 F200

This would power the laser at 50% power while moving the axes to 100mm X and 0mm Y at 200mm/minute.

I know it’s a bit late, but I think I have a solution. I have modified the smoothie post processor for Fusion360, and now it is possible to export laser gcode that the Boxzy can interpret.

Here is the guide to install the post processor: Install Modified F360 Processor for Boxzy laser

Here is a link to the post processor itself:

Hi Just Helping,

Thanks for this information. We should find the list of all commands which are understood by BoXZY. I managed with Fusion 360 to draw a sketch and finally laser cut just this. But it was not possible with direct use of the G-code file. Fusion 360 created a .NC file which is basically the gcode for a milling machine. To get the desired results with the laser I had to remove all G1 commands with movement along Z-axis (cut-in runs and the like) and I changed all feed commands to slower values as well as added L100 before them to activate the laser.

There is a post-processor BoXZY_generic which I have used, but so far I couldn't manage to find a laser setting nor was I able to add a new tool to the milling tools library. Didn't try the local lib so far.

interesting. You could write some conversion code to handle all of the changes for you.
