Mach4 General Discussion / No signal to laser pwm port

« on: March 27, 2024, 10:40:44 PM »

I'm sure this will be a easy fix and I am over seeing the issue.
My setup coinsist of Win 11, Mach4 4809 build, ESS 285 with laser screen installed I'm Using a MB3 BOB.
All other profiles work fine but I have been unable to get laser profile to test fire laser.
The ESS pin config. I have port3 pin 14 named as laser PWM, Port3 pin 16 named as Laser Gate,
In Outputs I have Laser PWM mapped to P3-14, and output#16 mapped P3-16.
Laser tab the laser gate assigned to #16. Allow test fire is checked.
My first thought was a bad 24v ( LT-80W-AA-Pro ) Laser but after connecting the PWM to a 5v source on the MB3 the laser did come on.
Tested P3-14 with ohm meter and no volts while test firing in mach4. I tried changing the power in ESS laser tab from 15.1 to 75 % and still no voltage.
If anyone could offer suggestions it would be greatly appreciated.
