MPCNC Primo Vacuum System(no travel reduction)

Hi, I’m working on a vacuum system that fit inside the available space, without reducing the machine movements. THIS IS NOT WORKING YET, it’s only a mokeup for verify the fitting, it’s too small and the idea is to double it up symmetrically, for increase the total duct section. Magnetic system is actually too weak to withstand the vacuum force. I will post here the following updates. [IMG_0768] [IMG_0763] [IMG_0764] [IMG_0766] [IMG_0767]
