I am wondering how the laser module works with a glass tube co2 laser. It requires a pmw signal (or 0-5v analog) for the power. It then requires a seperate on/off TTL signal of 0 or 5v to actually fire the laser at the prescribed power set by the pwm.
In the laser module example on your site it says the laser pin goes high and low for g0 and g1,2,3 moves. But I would also like to have a seperate pin that uses pwm to set the laser power. But when you read the laser instructions and the config file it only has one laser pin and it says that will be pwm to vary laser power. That may work for RF laser tubes or Laser diodes but it is not working for Co2 glass tubes?
How hard would it be to have the smoothie just have a pinA for the laser on laser of 0 or 5v TTL signal and pinB as a PWM power pin. Then like you say if g0 low g1 high it turns the laser on and off and you can type s125 for example to set the power (PWM) once and it stays that way the whole file unless you add another Sxxx command.
Otherwise it seems like I would just rather skip the laser module and have a m106 to fire the laser and m107 to turn it off etc. and say S128 once at the begining of the file.
