Stronk Machines 🔩
Added 2019-02-03 19:23:09 +0000 UTCJust got a CAD file for the machine which shows (again) how much effort went into that design: https://drive.google.com/file/d/1BBsQbnaCueyqj4zPCH2-i788HQAx2VYj/view?usp=sharing 🤯

From step file you provided I you can see place for ballscrew you mentioned, but from the video it doesn't seems like the part machined as in step file

2019-02-04 22:03:50 +0000 UTCIt seems most ball screw diameters are sized big enough to prevent whipping which is a problem for the longer length screws. A better way to do it in my opinion, is to use a ball smaller screw with a coarser pitch. That way you don't have to spin it as fast to achieve your desired axis speed. Whipping is eliminated and the inertia of the smaller screw is much less than the larger screw. A coarser screw requires greater positioning resolution obviously, so choose your motors appropriately. I really enjoy your videos. Hope this is helpful.

2019-02-04 17:12:10 +0000 UTCYour profile pic leads me to believe that you know what you are talking about :) How does one select diameter then? TDK starts with similar parameters to mine, but just jumps to the conclusion that at 1200 mm unsupported length 15 mm is too small. My longest ones are going to be 800 mm <a href="https://tech.thk.com/en/products/pdf/en_b15_069.pdf" rel="nofollow noopener" target="_blank">https://tech.thk.com/en/products/pdf/en_b15_069.pdf</a>
