need help for settings to cut hard wood. when i use LaserGRBL it seems to have more power then in Lightburn
It depends on the wood and a lot on how dry it is. Also if there are any cracks or imperfections in the wood, a crack will allow oxygen to get underneath and have a burnout. I dont know how thick youre going, i can just barely get through 1/2 inch poplar with a 40w diode, pine and cedar are worse, in fact dont waste your time with cedar. Im curious about oak, its such a tight grain it will be easier or worse. One trick you can do if your work is held tight, after each pass you can scrape the bottom of your kerf, then blow the carbon out…its hard to burn carbon. Also, after each pass you can drop your laser head down as deep as your cut is, that way your focus will be at the right height. As you get deeper you lose some focus. You get some side burning so expect about .030 to .050 kerf. And once you think youre through, make2 or 3 more passes because it doesnt go through equally. If you hit a knot, you can burn through it but it will take a few more passes because its so dense. Hope some of this helps.
My laser is Sculpfun S9. and i have try so many different wood material. but in lightburn is the laser so weak compare to LaserGRBL for some reason that i can’t understand
Maybe check the settings recommended here: Setting up the software - Diode Laser Wiki
Especially check if the S-value max is set to 1000 in the device settings window. Be sure that you added the S9 as “grbl” device, not “grbl-m3” or different.
Thank you for all help. i found some settings that was wrong and will try it out. I have also a Neje Master 2s is there any help setting even to that Laser ?
