In general, if you want to cut something, set both to the same. These are worth review for a more in-depth understanding of why:

Cut setting - minimum power?

Min Power is used for cuts where the head will be changing directions, slowing down the speeding up again, where you want to not over burn the corners. DSP controllers like the Ruida will ramp, within the range of the Min to Max Power based on the speed the head is traveling. Min Power set too high, over burned corners. Set too low, the laser will not “fire” and will not mark/cut in the corners. The firing point is the ionization point of the glass tube. The bigger the tube, the higher this poin…

Confused about best approach to min power setting

Thunder Nova series uses Ruida controllers. Jeff is spot on here. On the Ruida controller, there’s a controller setting called “Start Speed” that defaults to 10mm/sec. At that speed, power starts ramping up from Min Power to Max Power. Cutting at or below that speed means you’re using Min Power only, so if you’re cutting slow, set both Min and Max power the same and you’ll have no issues.
