That’s like asking a Ford dealer if Ford is the best truck.
I have a version of grbl based off of Inventables 1.0c that supports the laser with standard G-code usage.
grbl 1.1f has modified several G-code commands for working with a laser that are not standard usage.
What you would give up using my version is the ability to change spindle speed and feed rate “on the fly”.
If you really want to run 1.1f then you have to follow a different set of rules when using the laser. Some programs have been modified to deal with the differences, some have not.
Link to 1.1f laser rules.
I do not recommend 1.1f for laser work. For the spindle. it’s fine.
