I am trying to setup my Snapmaker IR laser to work with Lightburn. I used the Snapmaker software to set the focus distance but when I try to do a material test in Lightburn the laser is being driven into the base plate. (I have to e-stop before it hits). Is there a guide as to do this correctly? I have tried some of the items out there but none seem to give me the correct path.
Which of the Snapmaker devices are you using with the 2W IR laser?
Make sure to use the matching .lbdev settings file from this page:
We’ve recently sent them an updated version of those files, and they confirmed that they are working without issues.
I don’t know how this is done in Luban, but see if this helps: Adjusting the laser height using LightBurn
I am using the Snapmaker 350 with the 2W IR laser.
That would be the A250(T), aka the Snapmaker 2.0.
You’ll find the device profile and instructions in the links I posted earlier.

Thank you again Aaron, it worked! Now I just have to figure out what settings to use for the various materials. I haven’t found a guide yet for the IR laser so it will be trial and error.
Hey Bob
If you’ve run any other SM module before, you’ll find it just as intuitive. I normally use the 20w and the 2w is a really nice module to use and you can play with the Line interval effectively.
This power/speed test is very useful:-

While you’ll have to experiment of course, I find a good baseline for metals is to start around 1500-2000mm/min speed, 100% power, and about 0.05mm intervals.
For plastics, like black PLA/PETG, it’s MUCH faster. I use 6000mm/min with only about 40-45% power.
