LO 60W Powersupply Firing during "Frame" RDC6445

[dsudduth]

I have the following connections from the RDC6445
L-On1 -----> L
LPWM1 -----> IN
Gnd ------> G

Channel A is the LPWM1 output from Controller
Channel B is the L-On1 output from Controller
Pressing "FRAME" this is what I'm getting on the Fluke123 Scope
The laser fires even tough "L" is High (4.6VDC)


Here are the "FRAME PARAMETERS" in the RDC6445.

Here is what I'm getting when I press the "PULSE" Button.


So does this indicate that the Laser Power Supply is Ignoring the "L" input?

Is there anything else I can check?

[dsudduth]

When I send a job from LightBurn the laser is not turning off when it should. The voltage at terminal "L" on the power supply is toggling between .2v where it should fire the laser and 5v where it should turn off the laser.

Try not to use the PWM output from the 6445 but the 'analog' output. Give it a try
And, make sure you use 'low level' on the software.
