That is a function of the controller and Laser Power Supply. Well technically the digital panel technically outputs a pwm signal but its not continuously variable or controlled by software. NOTE: Neither panel provides PWM laser control. You can also add a potentiometer and make yours a simple, reliable analog panel and remove the bulky display and keypad. You can (and should) add a current meter to this configuration. The laser community would benefit greatly if we only shared current values (mA) specific to a certain wattage tube and forget about the arbitrary and terribly inaccurate “%”. Percentages vary so wildly i firmly believe those values should never be discussed. The big problem is, and we see it hundreds of times a day, is the “what speed and power do i use for etching edge lit acrylic?”. Digital panels alone are a horribly misleading monstrosity when not used with an add-on DC milliammeter. People who fitted an ammeter have reported 15mA as being anywhere between 30% and 90% on the digital panel. It is not calibrated to the tube specifications so the digital setting is quite literally a very poor guess. 100 percent on the digital panel means 100 percent of the total output of the power supply, not 100% of the the laser tube.
