Can't seem to find where I would invert the laser command, mine is on when its supposed to be off, but when a turn on command is sent it turns off.

I figured it out. You have to go into the Arduino GRBL programming and switch everything for spindle control from 1 to 0 and 0 to 1 then change the spindle range so that it's also opposite. Now anyone can connect a non Jtech laser by jumping the RPM and LZR ports with a resistor (I used a 1K, but will be using a potentiometer to see what the best resistance actually is). Then running your TTL line from LZR to TTL, and 12V and GND are just exactly where you'd expect to connect.
