I have connected the wrong poles of the E40 laser
however, currently, the laser head is still working normally
Specifically, I have connected P - G - ttl to ttl - G - P
I want to ask if that will affect the quality of the laser head?Your laser is perfect for my purposes.
This will not damage your laser, the E40 has very good protection and very strong quality, and the 4pin input can be connected arbitrarily without damaging your laser.
