I’m just i’m just curious Fred27, If you do have these changes documented any where and if you are seeing any advantages by doing so? I’m really interested to know. I’m just setting up my k40 want to squeeze all the control I can get at the low end of the laser power.
Also, if I want to go to single pin, TTL needs to be low for the laser to fire at all, do you just ground it?
I’m thinking to avoid confusion maybe some where in the Wiki it should say what to do with the TTL pin even if smoothie doesn’t use it. I know some power supplies ether need a active high or active low to fire the laser. I know from my experience connecting this incorrectly can leave you with a laser cutter firing at full power as soon as the power supply is switched on.
