I just checked the files, the holes for the ring system are not in any of the G-Code that I have put in the Community Garden. Here I merged the code between the predrill and 0250-1FL files to see where all the holes would end up.
This is proving to be a little problematic to determine the best way to add those holes to the part. I was able to find the file I had used to make the nc files in the Garden, but I had to dig through the previous versions of my nest file to get it. I added in the ring system holes, since the model is old enough that it predated me adding the system in. The only weirdness about doing it this way is that the holes are blind, and are drilled from the side with the counterbores, which would typically be facing down. However, all the counterbores are for the linkage systems, so they will not be needed if you’re making your sled with the ring system, so it shouldn’t be an actual problem.
This is the updated, nested model of the sled:
I also took a moment and made up a drill program for the ring system holes using the same origin as the nc file with the 1/4" end mill, so you can just run that using your same setup. I don’t have the Maslow post on my work computer, so I posted it using the GRBL post. Should still work fine for drilling.
