Hannibal's thread into DIY motion platform

Working on my pot pulley assy.. i try not to 3d print.. i dont trust my 3d print ability

figured out why my other 3 actuators were out of alignment... slight shift at the bearing block and top plate spells unsquareness for the ball screw.
i was able to align one for the night. to be continued.

ugh. 5th actuator couldnt be aligned. bearing block is uneven

Didn't you take out the inserts of the BK12 ? They keep it all nice and straight, just a thought

My Rig measurements

Just wow... i am grateful... i honor you by making a 6dof as great as yours..

Thank you! If u were a hot female, i would give u a big wet kiss, sir...

Haha no make it better than mine it's a lump of junk but it keeps on going somehow !!

Can't wait till I build a new one

@SilentChill I dont know how old u are sir. Young maybe.. energetic.. to plan for a new build! i think i would not have made it if i started with motors for 6dof.. (i am getting old) but im sure u learned alot in process .. but i understand your joy of the build.. its like sudoku..

In mean time my pot pulley assy looking like something

Looking sexy.. but half way finished with 1... 5 more to go

Started to put one power section together

Fabrication of my pot pulley assemblies

1 fully finished pot pulley assembly.. 5 to go..

Just some progress. Finalized my version of the anti rotation device.
used the nut housing which i plan to epoxy the carbon tube with, but increased the surface area by adding a PETG 3d printed 20mm ball screw spacer..

One actuator ready for power.. only after i manage to finish the power section..

a tid bit from back then..
i didnt realize that the BK12 bearing blocks had two bearings inside of different inside diameter. one was bigger than the other. some bearing blocks i had to open them up to switch bearing placement..

Eventually powet will be applied .. just dont know when.. :'(

Building again..

working on the power section.
but i have a question..
im following the wiring for power similar to sixdegreesoflight..

i am just wondering why he chose to have fuse protection for just power supplies instead of both the batteries and the power supples, since one side of the fuse block has both the batteries and sabertooth connected on positive...

@wannabeaflyer2 @SilentChill @Flymen @pmvcda any idea?

Hiya @hannibal , well I'd have to say its a choice really depending on who you see for Electrical advice , I Have both Options on my layouts ,see dodgy pictures attached ,
One uses a Main circuit breaker between Supply and shared Controllers . On the Other SMC version I opted for Fused connections to each Sabertooth and Only Main switch for 12Vdc supply .

Either way the thought was any Overcurrent would obviously / Hopefully trip the fuse or Switch( with resettable Fuse ) before electrical damage due to excess current could occur ..

But again I have not run my system for a long time but electrically those configurations should have been safe and fine ..

lol you are miles ahead of me, i havent even applied power to my build, i dont know if after 8 months of work, that my 6dof is functional... @wannabeaflyer2
appreciate your godly 6dof wisdom!!!

applied power to a sabertooth for a moment. it didnt blow up..
