12strings. Thank you for your reply. I am turning on the laser with the Spindle CW button. AND I was using the slider overide incorrectly as you guesses. I hadn't set a speed yet. Guess I need to get more hands on with Gcode.
So after starting SpindleCW and setting Speed (S50) via MDI, the slider "overrides" and is reporting back the speed accordingly. Thank you
I also confirmed with a Volt meter it is modulating properly. However, the laser seems to be at 100% no mater what the speed it set to
Another question, read below from the Laser Seller. I know his English is bad, its about the pwm frequency I have question
"When you connect laser to your controller board, please pay attention to the pin positions of 12v+ GND- and PWM/TTL, red wire=12V+, black wire=GND-. Yello wire=PWM+, white wire=PWM-(3-4pin wire). So Red Wire must be connected to the 12v+ pin on your controller board’s interface, Black Wire Must be connected to the GND- pin and Yellow Wire must be connected to the PWM/TTL pin, if you use 3-4pin wire, White wire should be connected to the PWM- pin.
if your controller board’s laser interface pins are in different position, please change the wires position to make it match the positions of + - PWM of your interface. If the wires connected wrong, it will damage the diode and the driver board.
Frequency: <15khz, PWM/TTL: 0-5V"
So, my laser has three wires, red (12v), black (neg) and Yellow (PWM). have the yellow set to output 1 on 424. It looks like the pwm frequency only goes up to 1000 Hz on the plug in which should be fine since he says <15khz. It just seems like the laser is ignoring the pwm.
Any suggestions? Tripp
