Get more speed in laser pwm/ttl

Hello,

I'm using a 2.5W blue laser. It's ok for lines but when are dotted not print well because It takes a long time to turn on and off. I'm using M4 S0~255 for ON and M4 S0 for OFF.

If the speed is high, the laser does not turn on. And if the bass comes on but then the long lines come out very thick. Is there no way to balance this?

Best regards

Sound like your turning laser power on and off, not ttl control?

Thanks Dust,

I have changed S0 to S5 and now works perfect.

Best regards

Wow, this is what I've been looking for, for such a long long time. Once I finish my new machine I will definitely use this tip!
