Is anyone able to kindly help me review my laser settings to discover my mistakes please? My laser settings were empty when I started up the new system.

A few months ago, I completed setting up my OptLasers PLH3D laser system with my K2CNC2514 using UCCNC's UC400ETH controller.

All of my laser programs worked.

So, I set it aside and built a bigger diy cnc system. Everything works perfectly - with the exception of my programs.

Pin 1 and pin 24 of the UCCNC's Port 2 are directly connected to the laser module; so, on the SPINDLE and I/O SETUP1 tabs, I set the values shown in the attached images.

The effect has been that in some programs, the laser is fired by G0 X12.4841 Y31.0987 F1000 M10 Q0 and not by G1 X12.5838 F1000 M10 Q255.

Below, the first code segment fires as expected and the following does not:

G00 G40 G17 G80 G50 G90

All assistance is appreciated; thank you.

I have fixed this challenge by setting the M3 relay pin and its port to 0.
