I'm 99.9% sure the shutting off mid cut is a bad controller adapter for the laser itself so don't let that part worry you It actually give a safety warning that is basically an ESTOP because it things one has been hit in the adapter. Troubleshooting this with Jim from JN Woodworks on YouTube we are both pretty confident it’s the adapter pro having issues. The power still flowing through PWM2 is not adapter related.

Using your modified code it DID NOT shut off at the end of the file BUT when I went to MIDI and entered G37 OFF and hit cycle start it DID cut power off to the PWM2 output! Very strange that it didn't work in the file though.

And maybe it was a fluke that the G37 turned it off last time manually. Just ran it again and it would not turn it off

Hello!

I have a theory and a possible fix for you, attached is a small modification to your PLC. Please install it by extracting the contents of the .zip into your C:\cncm directory and overwriting all files. Powercycle your system to complete the installation.

Let us know if this changes anything.

That seems to have had the opposite effect as we were hoping

Now PWM2 is putting out 2.5v and the enable output is putting out 0.5v as soon as the Acorn is up and running. As expected with this scenario as soon as I hit ARM on the laser controller it fires. I also tried the G37 OFF in MIDI and that doesn't change the output.

I rebooted my PC and AcornSIX twice after the first reboot after overwriting the files to be sure and it's the same each time.

Any updates? I found the files I replaced in the report before I did it and restored those so I'm back to what was happening before

Also I noticed that the VFD is kicking on and changing voltages when a laser file is run. Shouldn't the system know not to use the VFD if using the PWM2?

fyi chris is on vacation till after the new year.
please always post a fresh report.zip so someone else can figure out where you are at in the process.

The report I ran the day I installed the PLC updated test files is going to be more helpful than this one after I restored those files but here is the report I just ran.

Hopefully you guys are back from vacation. I haven't touched my machine since the 20th and am really hoping to get the laser PLC stuff working right.

Can you set Parameter 422 to a 1, this enables the advanced I/O Diagnostics. Then press Alt-i on the main menu. Looking at Outputs 17-32 (Analog 1/PWM1) and Outputs 33-48 (Analog 2/PWM 2). When you read 2.5V on PWM2, is there any outputs on (Green) in the range of 33-48? When off, i expect all analog outputs to be Off (red).

I generated a report with the original files in place. As soon as the laser adapter is turned on it shows 0% power as it should.

Then replaced the files with the ones sent before and ran another report and have attached both. All outputs are red.

Laser adapter shows 50% power as soon as it is powered on.

If I run a laser cut file it will modulate the PWM power from 0-100% throughout the cut as needed. my VFD is also being controlled and I can see the readout changing on it in time with the PWM power changing.

When the cut file ends the PWM will go to 100% power and will not shut off until I hit the e-stop. When I hit e-stop it won't turn off the PWM it just sends it back down to 50% where it was as soon as the AcornSIX is powered up.
