Hannibal's thread into DIY motion platform

i guess this is where my next area of time will go.....
thanks!

Hi hannibal...it's possible to have all material for replicate the actuator?...tks leoanardo

some parts were 3d printer but others were hand made like the pot/belt pulley assembly i think its easier to follow @wannabeaflyer2 or @SixDegreesOfFlight plans. i more of a paper calculations guy, so i dont have alot of it digital, rather on scribble scrap paper

i am running through the 6dof gauntlet and learning the hardway
something was off, and after my hard trip, i discovered that it ate the anti wobble ring..

luckily bearings didnt come out.. replacing now

after repairing broke anti wobble, i realize i have to stop messing around on actuators with power applied.
need to spend time away from hardware and understand more about tuning settings and the interfaces.

When everything fail, read the instructions.

Hi @hannibal

thanks for your thread and all details !

I am trying to design my own 6DOF and linear actuators inspired by you and @Dirty mainly.

What are final specs of your actuators ? (stroke, carbon tube outer/inner/length) and how do you joint ball nut and carbon ?

THanks a lot

i attribute my actuator build and design from @SixDegreesOfFlight @wannabeaflyer2 (the crazy tinkerer that likes to talk about bears lol) and @SilentChill (the 6 Dof freak.. )
my actuator spec is i set it for 11" stroke (could be more but im not going to push it)
using 500mm v slot 20mm x 60mm for the structure
carbon tubes are 500mm , with 25mm OD, and 20mm ID (other guys went 22mm/23mm..i thought that was thin)
25mm linear igus bearings.. (do not go steel bearings, i had my carbon tubes scratched) (go alibaba for 15$ a piece, unless u want to pay 60$ a piece from igus)
powered by E30-400 ampflow motors.. ( i been told its overkill, the E30-150 is feasible)
i am using 9mm 3d printer belts with GT2 pulleys.
custom hand made aluminum pot & pulley fixture with bournes hall effect 3600 degree 10 turn pot (36 $ a piece, if you going to make your own actuator, dont go cheap, u lose at the end)

how i attached the carbon tube is that i epoxied to the nut housing that comes with the ball screw (sfu1605 type ball screw), but put a 3d printer 3/4" spacer so that i have more surface area to epoxy the nut housing to the carbon tube with $$$ 3M 2216 A/B flexible epoxy. (photos a few pages back)

good luck.

welcome to 6 dof, be on our team

thanks for your answer.

My 1605 nut is 28mm diamter, how do you put your 25/20mm carbon in ?

owe yea, forgot about that... so, in between the 25/20mm tube, i cut a 1-1/2" spacer of 29mm OD 27mm ID carbon tube so it fills the gap. so first i epoxied that spacer to the end of the 200m tube, and then since the spacer makes it thicker, that end would be epoxied to the nut housing.

@hannibal thanks

happy new years.
im still working on my 6dof.. but at snails pace.

trying to finialize controller positions before i take down frame for additional welds

adapting my collective..

virpil and diy collective

protective table... 13inches high.. i hope its not too high to hit actuators..

And a mop bucket !

Man, so much time is spend to make it look beautiful.

thank you @Pierre Lalancette @SilentChill .. i just hope it will work, i feel like im almost building a tank.. i see both of you guys are going for mimimalist with lightweight materials..
