List 6: Test Laser PWM Output
1
Measurement Setup
- Connect multimeter red probe to GPIO.12 (green terminal)
- Connect multimeter black probe to GND
- (Alternative: Use oscilloscope for measurement)
2
Laser PWM Mode Activation
- Enter command:
M6 T2↵ - Switch to Laser PWM mode
3
Laser PWM Output Testing
- Enter command:
M3 S127↵ - Then enter:
G1 F1000↵ - Output should change from 0V to 2.5V
- Enter command:
M3 S255↵ - Then enter:
G1 F1000↵ - Output should change from 0V to 5V
- Enter command:
M5↵ - Output should return to 0V
4
Vmot Laser PWM Output (Optional)
💡
MOSFET ON/OFF measurement
- Connect red probe to MOSFET Vmot-main (orange terminal)
- Connect black probe to IO.12-MOS-GND (orange terminal)
- Enter command:
M3 S255↵ - Then enter:
G1 F1000↵ - Output: 0V to Vmot-main
- Enter command:
M5↵ turn off - 1.5 A maximum per channel. For heavier loads, use an external relay or suitable power driver; overloading can burn the MOSFET.
Expected Results
- M3 S127 + G1 F1000: Output changes from 0V to 2.5V
- M3 S255 + G1 F1000: Output changes from 0V to 5V
- M5: Output returns to 0V
- Mosfet output ON/OFF correctly with refer commands
