The laser preview shows it wants to go totaly off the work area. (I hope you get to see the screenshot) When I tell the program to print, the laser slams into the right rail makes a lot of noise and then aborts. I am a noob. Please explain like you were talking to a 56 year old that knows nothing at all about this. I have a 3D printer and wanted to try laser engraving.
I have printed my name on a pen a few times that is it. This does not happen when I preview Interval Test.
Please help

Ortur LM3 20 watt with air. I think Ortur uses GRBL I am not sure.
It’s because you send speeds to the laser that are way, way too high. Check those again. An Ortur Laser should use mm/min as units, make sure you set it this was in LightBurn main settings.
Otherwise, the units you see from other people with similar lasers do not match yours (you can use mm/s, but you need to devide all values by 60)
Thank you Melvin that did help.
after talking to Lightburn staff via email my Overscanning needed to be set at 0% instead of 2.5%. This helped framing issues.
Now my issue is the laser wont fire during the Edit Text part of the the burn. it goes through the motions just no laser.
When it starts the actual power and speed test the laser fires. Now I have a lot of diferent color squares on my metal/balsa wood (I tried this with multiple medias same results) with no numbers or words.
Any khelp would be greatly apriciated.
No. That just removed the issue, but not the root cause. Overscan makes sense and should usually be turned on. 2.5% is a good value.
This is most likely because you are running much too fast. Change the speed settings, turn on overscan and check again.
Text settings at 20000 speed 40 power burnt through the basswood and into the 3/4 plywood. Ortur web site says this is good numbers for engraving Paulowina wood. I assume this is the same-ish as the Basswood
The material setting test at 600 speed 30 power cought basswood and plywood on fire.
Thank goodness for a spray bottle of water.
Not sure what my test numbers should be.
Then there is something wrong with the settings. At 20,0000 speed and 40% power, you should not see much on a material with a 20W laser head. I guess your laser isn’t travelling as you tell it to.
I will keep trying to figure this out. I am sure this is a human (me not knowing what I am doing) id10t error. LOL
