It really isn’t but I was inspired by your builds and I first came across sand tables here when researching my Lowrider 2 so I thought I’d share it here.
I am a fan of round tables but I always felt the polar construction was pretty weird. I have a SCARA design in mind. Also, I wanted it to be low cost and achievable with what most of us here have: A CNC router.
And this is the concept for the gearbox and the arms. I have ordered parts to move the belt under the upper arm, allowing me to slide the upper and lower arm directly one over the other. I hope that will be stiff enough to avoid the lower arm being bent up by the magnet so that I get no scraping on the underside.
Still ways to go, especially with the software, but it’s been fun so far…
