i have a cheap “Good Laser A-11-4” Driver with 5V TTL on a mks sbase 1.3 with TTL configured on P2.5
If i set M03 S0 (or M05) my Laser is going to full power and with M03 S1000 he is off.
So this is inverted. I try’d some settings but cant get it working correct.
My wiring of TTL is, i get +5V from J4 with a 1k Resistor to -J17 and then to +TTL on the Driver.
Negative is direct from the main power connector.
I hope someone can help me with that issue, to get it work in correct direction.
