So I just thought I throw this out there.
I was at our CNC tonight at the makerspace I belong to and I was talking about how I really like the kinematics of my MPCNC but I wanted to upgrade my carriage. One thing that’s been mind candy for me lately is that I bought a aluminum casting furnace a few years back and I thought it would be cool to cast a replacement carriage out of aluminum. I’m also have a knee mill for metal machining and I wouldn’t bother me if was going to machine it.
One of my friends pointed out that machining for 606 bearings would take alot of work but if went with recirculating linear bearings that would simplify the process…
After thinking about it bit he does make a good point.
So obviously I would need to highgrade the tube so the emt pipe is out…
I was looking at ali-express and linear bearings don’t seem to be that expensive, although, I don’t know if I could find a hollow ground tube to replace emt.
The thought occurs to me that something like this could potentially be a upgrade to the primo as a 3d printed component, if someone wanted to say with 3d printed components but wanted upgrade.
At this point, my burly carriage is pretty shot after many repairs and I’m wanting a bit more.
Has anyone done anything like this yet?
