But the laser with no TTL control line burns strong.

Yes. There are some lasers where TTL is inverted so it turns off with high input - not sure what engineering school those laser designers went to but I'm guessing they failed  ;D

Ill probably mount the 3w and mobe on for now. The 10 watt is backwards a bit. The stop laser command turned it on and i was very lost.

Check out the logic... 1 = OFF and 0 = ON  :o

If it's like this you'd need a TTL logic inverter capable of 8kHz switching.

Stepper issue fixed. Now for the next issue. So if i plug into TTl I get no response from the laser. i assume its because its wired wrong. ( high power turns it off, not on). If i plug it into my normal laser port on the card, I can turn the laser on by turning the laser off in T2. So its backwards.

Best fix for this issue?
