When im trying to cut 3mm plywood it takes about 5 passes at 100% laser power.
I thought 100% was the maximum ?
But on the move yo can adjust the speed and the power.
So when i adjust the power to 200% on move
it will cut 3mm plywood on 2 passes , why can I not put the cutting power to 200% which works a lot better !
That’s true if the LightBurn S value max matches the GRBL $30 value, which are typically both 1000 these days. In that case, any increase of power beyond 100% does nothing, because it has no way to increase the output power beyond the $30 setting.
If the #30 value exceeds S value max, then 100% power isn’t actually producing the maximum possible laser power and the controller can increase the actual power using those adjustments.
Check those two values and, if they’re different, that’s what’s going on. If they’re the same, then something else is happening.
$30 is found in edit>machine settings (machine must be connected.)
S Value Max is found in edit>device settings. This value must match $30. Typically 1000.
