Lasertree K30 Laser

Good Day

I am using a laser tree K30 and tried all the settings on light burn software to get the laser to cut as per the manufacturers information I battle to cut 6mm MDF at 100% power, I set the parameters on machine setting and device setting to first 1000 and then to 10000 is there someone that can advise me on how to get the correct settings.

Maybe your Lightburn speeds are in mm/s instead of mm/m?
