I found a repository on github for post processor for Vcarve or Aspire software. I modified the file to work with my setup and marlin, by removing some of the g commands my setup didnt need, which is working, but I want to add a 4 axis and I need a wrapped post processor. I am just setting up my 4 axis now so I can not test it yet, but I was hoping someone who knows more about G code to look over what I have done to see if there is anything else needing changing or stands out. I listed the changes I made in the comments at the top of the file. Thanks,
