Okay, I found this thread,
Create Path in CNC processing no longer works
It had the 99%solution to the problem if you’re running Windows. If you’re running MacOS, the file that needs to be deleted, not modified, machine.json, can be found in the following directory:
/Users/EASchmidtE/Library/Application Support/
This path had to be accessed through the Terminal window using what little knowledge I have about a Command Line interface. Trying to access this folder through the GUI Finder on my MacBook did not work because the Library folder is hidden. I used the list ‘ls -la’ to display the contents of each folder. Then, I used the change directory ‘cd’ to change into the folder that I wanted to go to until I found the file.
I tried to modify the file at first by removing the server name like the above thread said, but it didn’t work. Once I deleted the machine.json file, I was able to get past the error screen and create the toolpath for my project.
