I have a problem with the laser power setting500x700 red + black 80W China laser. Originally with Topwisdom, upgraded to Ruida RD6445G (because of Lightburn )
I noticed it yesterday.
If I cut a 3mm MDF, you can watch it.
At about 20mm/s and 30% power, the cut almost gets through.
If I increase the power now, the cut should be through, but it doesn’t. Nothing changes from 30-100%.
The power value is shown in the controller display as it is set in the software (RD + LB). Laser setup in Ruida is from 8-99%.
What could that be?
Unfortunately my ampere meter is still on the way, so I can´t check current.
The tube is KH (80 / 85W) and the power supply ZYE MYJG80R (black housing, RJ45 socket, without display - not the blue one), both less than 20 hours .
