Just finished upgrading my K40 to a T9+ DSP and new Motor Drivers and so forth. As a final step I replaced the Laser Power Supply with the LO Smartbean 60W PWM CO2 Laser Power Supply. (I am still using the original K40 glass tube.)

Problem: Whether using the manual laser button (Control Panel or Power Supply) or running a drawing, the Laser just fires a short pulse, then no output. I've tried different power levels and checking other hardware related settings, but it behaves the same. Just a single dot flash. (The stepper motors run and the head traces the path it should, just no laser.)

I assume it would be a setting issue since I'm still figuring out the T9, but before I post a bunch of extraneous info I hope someone can offer some specifics to check?

Thanks,
Mike

Please show your wiring and laser setting parameters.

Okay, it's working.

I had everything wired temporarily to accommodate the new DSP, new LPS, mock-up control panel, etc. So all that wiring had become a rats nest. In trying to look for bad connections I gave up and re-did the wiring properly. Now that it all works I believe my problem was loose connections to the digital current meter causing intermittent failure of the laser cathode connection.

Lesson learned. Neatness counts.

Hey at least you got it working now, you need to give yourself two thumbs up!
