A 3D printer runs on a 24v power supply and uses a 50W resistive cartridge heater to melt the filament. To avoid damaging some components of your printer, you want to restrict the power to the heater so it is never more than 35W. Fortunately, the firmware for your printer allows you to set a maximum PWM duty cycle for this heater. What should your maximum duty cycle be
