Hi everyone, first post.
I am running Mach 4 with ethernet smooth stepper.
Basically, I want to change the colors of a LCD strip based on the machine status (motors enabled, cycle started, etc.)
In my ESS configuration, I have set output 49 to port3 pin 9
I managed to create a button that pulls the pin high when I press it.
What I want is for it to pull high when I press the "Enable" button (the one that enables machine controls), and pull it low when I press disable
same for spindle start and cycle start
where can I find the script that this button calls
what lines do I need to add
So far I have only found scripts regarding the screen (LUA)
Thanks!

I think what you want is to copy the machine enable state to your output. I would just use the PMC Editor (Configure > PMC) for that.
See attached image. This will run every 10 ms and copy the machine enabled signal to your output 49.
To do this, you can do this:
1. In PMC Window, click Settings > Code generator and select LUA
2. Instruction > Insert Contact
3. Double Click newly created contact and configure:
- Source: Core Output
- Name: machineEnabled
- Device: Signal
- Object: Machine Enabled
Accept with click on ok.
4. In PMC Window move the cursor behind your newly created contact by clicking there
5. Instruction > Insert Coil
6. Double Click newly created coil and configure:
- Source: Core Output
- Name: output49
- Device: Signal
- Object: Output #49
Accept with click on ok.
7. Click File save and save the pmc to C:\Mach4Hobby\Pmc
8. Click Generate and save the lua script there too
Then do what is described in this video at 4:47 to enable the PMC script:

It should work then. Add in PMC another rung for cycle start and your other output. Dont forget to hit Generate again.

You could also just use the Output Mapping of Machine Enabled directly to your Port 3 / Pin 9. This would work out of the box but would only work if you do not already got a pin mapping configured there.
To do this just click Configure > Control and select the tab "Output Signals". Scroll down until you find "Machine Enabled" signal and configure it.
Mach4 has many of these prebuild signals that one should use.

Setting it from the control--> output works like a charm.
But, I get this error when trying the PMC way.
It works just fine in the live simulation...

Went to said line that the error code stipulated. Somehow i figured my problem.
I had saved my MPC as LED control. Didn't like the space there. Saved it again to LEDcontrol. Compiled, boom. Works.
Thanks to everyone!
