Hey Guys and Gals,
recently purchased a Elekmaker A3x.... there was no documentation so with some help from goodle and youtube i got the thing working and engraved my first project....
the thing is... in the kit there was a small adapter PCB, with a power jack on one side labelled "in", a jst connector on the other side labblled "out" with a button in the middle labbelled "pwm/ttl test"
so my question is... where does this sit in the connections of my laser engraver?
i cant even find any reference to this little device with a google search.
id really appreceitate any input from someone in the know.
