Sorry if the pics are a bit disjointed realized that I didn't take nearly enough.


Still very much a work in Progress

Reserved

So will start with the Basics.
Used most of the design for the actuators from Peacemaker's unicorn build.
but decided to go 600mm 1610 ball screws this meant I had trouble getting carbon fibre tubing in the length I needed. So ended up making the shafts out of 28mm stainless tubing, luckily I have access to a machine shop through my Job. also struggled to get the Igus bearings at the time of my build so machined the end caps of some High strength low friction plastics that we use for industrial screw conveyors at work.

Next was the frame must admit I didn't do much in the way of Calculations for the extra size in actuators just increased Peacemakers sizing by 10% as he had suggested in one of his posts.

Ended up having to cut 100mm out of top frame due to it being able to hit on front actuators if at full extension on pitch and roll.

While I was modifying it a built the monitor stand and steering wheel mount.


Wow I didn't realize how much mess I had around until I went back through pics

I will clean it up when I'm finished (what I keep telling the Missus )

Pics of Temporary Wiring setup and my Daughter helping out for a school project.

Took a ridiculous amount of time to wrap the power cables to stop EMI whish I had read about it before ordering the motors, would have got shielded cabling ...Dohhh

First Movement....Yaaaahhhh

Nice work mate!! Looking good

Nice work @Pinballcat . great to see another 6DOF up and running . Did you CNC your Actuator Plastic plates material looks like the stuff i used ( Delrin ) Acetal co polymer . strong stuf and greast for machining ,

Just gotta add one minor Proviso regarding the Upper frame , i have to add from experiance that when tuning these systems ( whilst learning the setup) scuse the language but S'#t happens and these actautor are pigging seriously fast and Powerful , so only thing id say you may need to beef up would be placing some gussets at various weld joints cos when these things hit bucking broncho mode they are visious ( ask me how i know LOL ) as always No critisism intended as you have done excellent work fully loaded seat and fast acxceleration in event of test crash are violent , Mind You @Peacemaker105 and Others are running fine so may not even be a issue for you .. Lovely work and man cave to diee for LOL Great stuff

Cheers
I considered the gussets last time I had it apart to modify the frame height, hence why the actuator paint job looks a bit beaten up.Will upgrade the whole frame once I am happy with it. I made the guides on the milling machine at work on 12hr night shift...nothing like getting paid to make parts for your sim lol..The material is Dotmar not sure of the numbering , we use it for wear guides on conveyors at work, tried to use 3d printed ones but cracked one while installing so wasnt happy with strength even with pteg, have the speed in the controllers set to 1500 at the moment as still struggling to get a good basic 6dof preset in simtools. the man cave has been sadly neglected over the last 6 months or so due to the motion sim have sold off 6 arcade machine to try and create space for it. If you love Pinnies and ever get to Tasmania look me up have 19 in the collection now

Finally managed to get the rig moving well couldn't get a decent 6dof axis preset working in Simtools. so At the suggestion of @Thanos and @Peacemaker105 I decided to give Mover a shot. Worked a little too well wish I had a Vid of the first run with no Filters. The second is still pretty violent. Thanks, peacemaker for taking the time to send me some profiles, made all the difference once I saw that the Actuator numbering swap check box is in the Pose's

Tomorrow I'm Having a clean up around my Room

Use a green screen behind it, to place it in a nice scenery background, like a tropical beach maybe

great achievment!

oh yes, +10
don't play with your safety (breaking the sim is one thing, hurting you or a nice by-stander is another thing)

Hi pinball cat its coming along beautifully mate. Im in the process of starting mine. Quick question.
How did you work out the sizing of the top frame in particular the distance of the angle bracket apart from the where the rose joints attach to the brackets. My base is identical dimensions to peace makers base. TIA

Photo attached for previous question

Hi Nuno
sorry I hadnt got back to you but have totally rebuilt my rig so I could access the seat easily and install triple screens, hadnt posted any pics yet I will do up some drawings and send them to you if you still need them

Hi mate I've worked that part but thanks for replying. Did you use m10 rose joints or m12? And stainless steel bolts to go through them? Thanks mate

I used m12 but the cheap ones from alliexpress flogged out within a couple of months so would recommend higher quality ones , I used stainless cap head bolts as I could turn them down on the lathe at work allowing them to work as alignment spacers
