OK, thanks I didn’t realize that was there.
Unfortunately that will not work as F360 thinks that a PP is a single .cps file. The Guffy PP provides 3 different but related PPs. It does this by moving all the common code into DIYCNC_Common.js that is then #included into each of the 3 different .cps files.
When you use the import button it only copies the .cps file and then there is no DIYCNC_Common.js so it fails when run.
The other option is to wait till you run the PP and where it shows the file path use the … button to select a folder (on your computer) that has the files. On later runs you can simplify this by using the Setup button and then select Recent from the bottom of the list and then select the folder you used the last time.
One final option, I’ve created a version of the Guffy post processor. See below. The zipfile attached to that post has the files merged. Once extracted from the zipfile that Post Processor can be installed.
