You can try with one motor at the time, no need to remove the top platform. I think you can let the arms do full rotation without hitting the frame or supports right?Just make sure you cut the +24v power to the 6DOF ext board to avoid generating signals from it while its auto-tuning. I set all these H001 and H002 parameters but when he was pressing the start button on the VFD, no motion was happening. He told me some _ _ _ _ (lines) where appearing on the LED screen but he (Mike) was not sure what they meant.
I completed the Auto-tune (H001) on each VFD but I had to do with no rotation as my arms would hit the braces. I was able to complete each one with no problem. I got the _ _ _ _ O symbol at the end which shows it completed. Do you think I should complete with rotation? I can remove the brace if you think it would be better. I installed my upper MDF platform over my steel frame tonight. Looks good as I'm getting ready to mount my triple monitors and seat to the platform. The new base gives plenty of support to step in and out of the simulator, plus it safer when you are making severe banks....... Once done its time to paint!!
Ok....I'm tired but I have a few more questions. I tried to run the Auto-tune, H001, except this time I chose with rotation so the VFD's will tune based on the motor torque of the rotating arm. I am getting accel and/or decel error codes on my VFD when I do that. I can run the Auto-tune in no rotation mode and it completes no problem. When I first used my VFD's I increased my F002 and F003 to .15 in order to get the platform to work without getting a accel or decel error code. Should I increase the value in order to run the Auto-tune so it does not error? Does that help the platform when I raise that value for both accel and decel? How high can I bring that value up too and what will it mean to the performance?
PS- Fabi has an Accel and Decel ramp time of 0.5 on his VFD's, should I go that high?
I went ahead and changed the Accel and Decel settings from 0.15 to 0.50 under F002 and F003 on my Hitachi VFD. By doing that I was able to complete the Auto-tune, H001, with rotation, 02, and it worked for all six VFD's. No Accel, Decel error codes!! This is one step no one should overlook as it made an even bigger difference when I put the platform through the motions. Before the Auto-tune I would sometimes get a slight chatter on abrupt moves through the mid point of the arm movement where the load was the greatest. I'm not getting that nearly as much even with abrupt forward, reverse changes I make with the x-sim sliders. Much smoother than before which I thought was pretty good. I might even try to raise the "P" value to see what happens.
For those who have this VFD you need to change your H002 setting to 02 so the drive knows to use your Auto-tune settings and also A044 to 03.
I was using rfactor and was racing to see how the platform reacts and it was awesome. Lowered my motor speed to 50% as it is more than fast and powerful enough at that %. Lowered my Accel and Decel settings back down to .20, no problems with any errors. The platform is quiet with very fluent movements. I tried X-plane again with the BFF software and I came to the conclusion that it's not so much the game that is causing the platform to act jumpy it has to be because my laptop for testing. It cannot process both the X-plane software and the BFF software. Both are taxing on the processor. I see the screen jumping in X-plane which I think has a direct correlation to the platform movements. I'm not going to stress on that until I run it on my larger system. I have a feeling its going to run much better on there. I was reading that if you are running both on a older computer it can cause the platform to not act properly due to the inaccurate movement cues from X-plane due to the processor.
Thanks Thanos, I had a feeling that could be the issue. You can download the settings directly from the inverter with a USB cable and the software which I downloaded from Hitachi. I will download my current settings and post them here along with the link to get the software, which is free, so anyone can manage their settings. You can load up settings right from the software.
Here is the link for the Hitachi VFD so you can download and upload settings if you choose. You need to set up information on-line to gain access, no biggie. I will post my settings once I get a chance too.
Here is a video of me trying rfactor with my old Playseat mounted, to test out the motion of the platform. I lowered my "P" setting to 18 and lowered my Max Speed to 45%. As you can see there is still plenty of movement and speed. The platform is quiet, the sounds of the springs in the Playseat were driving me crazy....lol!! The only issue I am having is that I am getting random errors in the VFD's. Either Acceleration or Deceleration. I have changed the setting to .5 for both but was wondering if I should make it higher? I increased my external brake resistor to 90%. Ideas on the error codes? Please no critiquing my driving as I was looking to my right at the screen and a road I could hardly see. I had my fare share of riding over the grass. The simulator lets you know it!!!
On another point, I tried to install my larger platform you see in my Avatar. It's not going to work as the weight is too much for the front motors. They are overloading and shutting down. I'm going to have to scrap that idea and go more traditional like others to keep the weight down.
I'll post more as I progress with the upper platform. I'm working on my triple monitor stand (Tubular steel) and I'm going to make a new complete wooden platform to cover the steel pad. I'm going to use 3/8" Baltic Birch plywood for strength and weight for the finished upper platform. Also easier to mount my metal frames too.
Some inverters have a feature , function to follow if the ramp up and down happened correctly (according your setup).You can disable this watch out function which no necessary in our case. You don't want to know if the ramp up or down happened good but you want real motion ! ;-)
I just removed the private setting from the video. Sorry about that. Not sure why is was on. Take a look if you like now. Thanos, Vic brings up a point in regard to the VFD. Do you know if the Hitachi WJ200 has that feature and maybe you can tell me where to find it to disable??
For me it looks very good ! It's fast and smooth in all movements.With the screen of the game it would be great to watch how the simulator reacts according your drive ! Lol ;-) But anyway you are on the right settings !! For the function I don't know th WJ2000 but try to have a quick look.
dureiken: Hi there, it's really quiet here someone could help me for my 6 dof project ? thanks a lot

tronicgr: dureiken Hi, Open a thread and I'll try my best to help. A little busy with Kickstarter details at the moment but I'll see what I can do.

fimmy: How's the firmware going?
Sept 6, 2017 8:34:43 GMT
tronicgr: @fimmy I had to put it on hold to finalize the manufacturing of the new kickstarter controllers. I tested parts of it to ensure compliance with the new features and looks good so far. I'll get back to it soon for integration.

Theuns: Very nice design.I'm also busy with mine and changing it also to Linear Actuators with 220v Servo motors.I'm waiting for my new controllers from Thanos. If I may ask Do you have any Sketchup files of your design and willing to share it I Thanks Theuns

atayeu: Hey everyone! I'm reading up and gathering all of the intel I can find for my first motion platform. this is by far best information for creating one.

tmcnam: I must be crazy but I still can't find the blueprints to the platform by GA-Dawg. Any help would be appreciated. Thanks guys.

Trip Rodriguez: Sorry tmcnam, the shoutbox doesn't get much attention. Did you find the blueprints? They are at the VERY bottom of the extremely long first post. It says "attachments: 6DOF.zip
