I am running Lightburn with Neje Master 2 20w with GRBL 1.1f firmware. The laser light is not powerfull, it marks the wood, but is very weak. I havematched the spindle speed in the firmware with the device setting ‘S-value max’, both at 1000.
It does work if I put a much higher value in the ‘S-value max’ setting, and leave the GRBL setting at 1000. So for instance, s-value max at 32768. The laser is much more powerful then at 100%.
It is workable, but the power settting for a layer is not lineair anymore. For instance, anything above 10% means the laser is on full power.
Any idea what could be cause? Thanks.
Great software, lightburn, I am thinking of buying it.
