Ok still not working. I’m wondering if it’s something in the way I have my Mach3 set up.
I use a warp9 ESS and a G540 for control.
I have the two TTL wires from my laser running to port3 pin 17 and a ground pin on port3. The rest of the machine is controlled through port1 on the ESS and sent through to the G540.
M3/M4/M5 do not activate the laser I think because I have M10/M11 checked in my ESS plugin settings which to my understanding disables Mach3 settings.
Is this the case?
Would it make a difference if I connected the laser direct to the G540 port#1 output #2 instead of using port #3 on the ESS for just the laser?

Any ideas?

Ok Scratch the previous post. I Walked through all my Settings one more time and managed to find that I had a step pin wrong in the Mach3 set up. M3 and M5 commands are now working however my new issue is regardless ofMDI entry:
M3 S001 or S100 I get full power every time.

Another suggestion...

If you move on to Mach4 then your ESS will allow you to gate the ESS generated PWM and Mach4 derived M62/M63 switching signals into one output which you can then connect to the TTL input of your laser. If set-up correctly this will then enable your laser to be switched ON/OFF at any chosen PWM power setting.

Thanks tweakie.
I was reading over post #3 which led me to the other original posts Because I signal active low and down the rabbit hole I went. I am completely new to this so I have to go out and research just to comprehend some of the things you where referencing. Moving to Mach4 sounds much easier. I may just manually zero the laser in the meantime in Mach3 until I get the Mach4 trial setup and learn it. Seems like it’s for the best that I make the switch.

The ESS also supports laser raster engraving with Mach4 and this may be of interest to you; https://warp9td.com/index.php/faq/faq-mach4#LaserSetup

( initially it may all sound a little complex but once you get into it then it starts to make sense  ;)  )
