Latest CAD model. Note that I did not design the gantry. I paid 30 usd for the model. It is the "ripper cnc". I just changed out the base by removing the aluminum extrusions and adding the granite-epoxy. I was thinking of making the rectangular sub base out of cement instead of epoxy. It only supports the granite epoxy table which will be supported by 3 points but no physical connection. To fit the gantry model I had to make the table larger which makes it weight in at 300kg according to the CAD software when modeling it as cement. This is a bit if a problem for me. I am planning to cast it in my attic and then take it out of the building by elevator to a commercial space (which I don't have yet).
