Thanks for this nice design, I am not sure about calculation of pulley ratio. Could you give the exact pitch of screw and number of teeth pulleys. Or can you give a formula involving pitch, diameter of drum and pulley ratio
Love this video, it is very helpful! How did you design the screw and get the intersection so clean. -Did you use the thread command or the helix/ spiral?
Hi...great design Few queries.. I couldn't understand how cable gets wrapped around the bigger drum... And what does that encoder do at the knurled wheel location?
It looks like only one drum... the larger roll of cable is just to show how large it can get. The encoder feeds back data on how much linear length of cable has passed, by converting revolutions of the wheel x circumference of the wheel.

Nice content! Looking forward to more sharing brought by you!

Thanks! To make the screw I believe I just did two swept cuts. I made two helix curves (using the helix tool) and swept two square profiles
Great job!
Nicely done
Can you tell me the maximum speed that the self reversing screw can reach?
Hi...great design
Few queries..
I couldn't understand how cable gets wrapped around the bigger drum...
And what does that encoder do at the knurled wheel location?
It looks like only one drum... the larger roll of cable is just to show how large it can get. The encoder feeds back data on how much linear length of cable has passed, by converting revolutions of the wheel x circumference of the wheel.
Great video! Can you point out or point me to any resource on how you optimized the nut and/or screw design for a smooth transition on either ends?
With a self reversing screw the transition should naturally be smooth at the ends
Great Job thanks
All my questions resolved
Awesome!
Hi, what type of motor did you use?
Great job thanks ......Can you send me this design please ?
See link in description
hey bro where you buy that reversing lead screw?
Robot digg website
thank you bro
