I'm curious as to how you machined the bolt heads with the ball head mill.
I was looking at magnetic arms for a MK but they used cylinder magnets in the arms with steel balls on the effector and carriage.
Your way seems cleaner to me since it seems like it would have more surface area for the the attraction between the parts and be easier to assemble. I have a feeling my MK will be busy making parts for one of these once I get it going. I wanted to scale up to a 250mm build surface and 2020 extrusions anyway. Would the Misumi 2020 be an adequate substitute for the Bosch/Rexroth extrusions? I already have some 360mm and 750mm handy.
