Checkout my laser setup guide here: [Mach4\_ESS - Google Drive](https://drive.google.com/drive/folders/1kcfer3rpIbMMldqdWtIihjJHW9x3FbfB?usp=drive_link) I also have post processors for Vectric and Mach4 in that same directory, as well as some screensets that add some laser features. ---

Hey Jim, I am still unable to get the laser to fire from mach 4. It will test fire from the adapter pro. I have checked all the wiring and everything is tight. I have checked the config pins and everything seems to be in order. I have set it up using your post. I am at wits end if you can help I would greatly appreciate it. ---
