Machine: Cinese K40 3020
Board: Cohesion laserboard
Problem/ Question: Problem with laser control cennections on HY-T50
I have to wire a new PSU (HY-T50) to the Cohesion3D LaserBoard card and from the seller’s site there are two possible types of connections: “High-level light control” and “Low-level light control”.
The first (High-level light control) uses a potentiometer to vary the connection to “IN” from 0 to 5v
The second one (if I understand correctly) assigns to the software (I use Lightburn) the power management (PWM?).
Reading other posts on this forum, I realized that the best solution is to set a maximum value (15mA for example) with the potentiometer and then manage the power in Lightburn that in any case will never exceed 15mA even if set to 100%: in practice a middle way between the two possible connections.
My problem is that the HY-T50 does not have an “L” output but controls the laser with the “TH” or TL outputs depending on the configuration.
You could confirm to me that the correct connection is the second one and that I have to connect the Gnd and the “TH” output of the PSU to the Choesion board.
