Machine: Full Spectrum Laser 5th Gen
Firmware: n/a - not there yet
Hello Everyone, and thanks in advance for your input. I am wiring up a Laserboard to replace the stock FSL controller. In the process I am installing an ammeter and a laser fire button. I have most everything wired, but before connecting the laser fire/ground to the Laserboard (and even powering Laserboard) I wanted to make sure the Laser fired properly with new button etc.
Using 10-turn pot and ammeter purchased from cohesion, wired as diagram attached depicts.
Pot might be wired wrong, maybe 5v/ground flipped as counter-clockwise seems to increase power.
Laser Power Supply makes a skrrrrrrr sound when test firing. register about 4 ma on meter. When I increase potentiometer (counter-clockwise) and fire again no skkkrrr sound and gauge jumps past 20ma.
Ok you say find the sweet spot between those situations. Nope, seems to be either or. I am about 1 turn from the end of the pot, and the tiniest change will jump between those two outcomes. Didn’t test too much as the 20ma consumption seemed too high.
Thoughts on wiring? I currently do NOT have the laser fire/ground connected to cohesion laserboard, so there is basically no connection to board currently.
hmm. new users cannot upload images. maybe this link will work:
