CAD & CAM Tool Chain LaserWeb/CNCWeb Suppport

When I generate gcode using LaserWeb3 I was kind of expecting to see some Lxx commands in there to set the laser power dependent on the settings in the job. But having examined the generated gcode file I don’t see anything like that. I also see that irrespective of what I set Laser Min and Laser Max to my ammeter is telling me I’m doing a 100% power burn.

This didn’t used to be the case. After the fine help from @donkjr I found I could control the power of the laser. However, after going to latest smoothie and LW3 I seem to have lost the ability to control power.

I’ll start going back through different revisions with a test burn on each to see if I get anywhere

LW3 has power control settings. In the main settings you can set the maximum power as a global item. In the CAM tab you can set power level for each item. But remember, Smoothieware power levels are from 0 to 1.0, Grbl is 0-255

@funinthefalls … aaaaand that would be my problem. Had PWM Max S Value set to 255 for a Smoothie board. Damn it!

Glad we could help sort it out quickly.
