Here is my cambam file of a single sided 12"x12" vacuum jig that uses 1/4-20 square nuts for a bolt down solution ontop. The nuts will get a small piece of tape on the back of each nut so vacuum leakage doesn't occur. The main gasket is a 1/4"x1/4" gasket, the groove it sits in is only 3/16" so that gasket can compress. I didn't include the 2nd piece (where the vacuum nozzle attaches). If anyone is interested i can load it up. *material is .500" HDPE*
Anyways, if anyone can load it up and see where i can save some runtime it would be much appreciated. I have gotten it down to 58 minutes run time. (50ipm max, using 1/2", 1/4", and 1/8" end mill). (the video is a few hours old and doesn't reflect the new changes in the current atttached file, part is the same, but the tool paths are optimized a hair better shaving off almost 8 minutes)
thanks!
