Showroom 3070W 6DOF Seat Mover (WIP Surge_Sway table)

Oh inline winchs are as noisy as hell, yes will need a sound dampening box indeed. The planetary gearbox inside them werr badly indeed but are stronger than the ones I were using.
BTW nice use of the bike pedal bits, recycling , love it.

Using tons of grease make them less noisy. Furthermore I made a platform with two stones. The winches are mounted on an absorber. Please if someone knows if I'm on the way with my electric issue thanks for helping.

Notice you got the pots attached, more bike parts , cool.
Well have you been able to test them with Prilads control program, if all is correct the next step is to make SimTools do it magic.

only to be sure: with SimCTRL the winches make the oscillation if the pots are in the center position. If I turn the pots outside of the center the winches rotate in the direction where the pots have turned.

So I have troubles if the power goes on and if the pots are not really in the center the winches begin rotating (and bashing the pots...).

Hi Pit,

If the motors turn on and continue in one direction you probably have to reverse the polarity on your motor. The idea is that the motor will automatically turn until it centers the pot. If the polarity is wrong it will think that the pot has not yet reached the center point and keep going. One good reason to make a slip type attachment for the pots.

EDIT: One way to check if you have the correct orientation for the pots is that if the pot shaft and the output shaft of your motor face the same direction the motor must move in the opposite direction as the pot. If the pot turns clockwise to show increase the motor should move in the opposite direction to counteract that movement.

Edit on my Edit, lol: Since you are using a chain drive rather than a gear which would automatically reverse the direction of the pot you have to do it via the electrical polarity.

Hi Historiker, in this case the motors stops, but not if the motors are already outside of the center and moving on the "wrong" direction. I hope I did not expressed myself incorrectly...

Pit, that reenforces my comment that the motor polarity needs to be reversed. See the additional information that I added to my last post as an edit.

Sorry I was reading the EDIT to late. Now I understood (I think ) and makes sense. Thank you.

Correct guys pots need to turn opposite to motor or the motor will never find a position that is set.
Ie pot turns right , motor should turn left. Can be tested without connecting pots to lever, a slip joint i can not recommend as when the sim is under full power and bouncing along with road noise very fine vibrations at 10ms they will slip and you centre can go out badly. But on the other hand for setting up with a driver that has no real fail safes to stop the overrun then yes be a good idea before you start destroying pots. Jrk has an inbuilt out of bounds setting so if they do overrun(very rarely) they just stop until you reset them, another good thing on Jrks. This really needs to be added to an Ard code for safety, think @RufusDufus code is the only one containing this not sure if prilads has it. The others just overrun and destroy pots.

Some arduino code don't have fail safe because a smart way is to reverse motor's direction if position may go outbound. ;-)

No worries I like fail safes like if pot breaks on Ard the motor spins out of control and flat out too. Had that problem myself, I was just noting that the Jrk uses a feedback out of range to stop this issue and felt it would be a nice addition to the Ard , not to persway the user to change, my attiude to the Ard has changed , people here onsite have proven its a viable and rather clever controller that can be used in many different ways. Sorry to all if it sound like anything else.

Yes, ideas are interesting to share I'm still curious about how to detect outbound if pot is broken... independently of the board behind.

The JRK has a built-in feature to test, if the pot is still correctly connected: http://www.pololu.com/docs/0J38/4.f
see the Bit4 and Bit5 parts

So for now the best solution is to not to have wait long until the pots are broken

...perhaps I need emergency stop switches at the higher and lower end of the rotation to be sure.

Hi guys it works perfectly. At least the Arduino code by Prilad is genius. While testing XSimCTRL one pot has run outside of the 100%, all motors stopped immediately.

It is working using (SMC3 Arduino 3DOF Motor Driver). With the Arduino UNO/Duemilanove 2dof firmware I got some problems. One motor was stuttering and not turning with full speed. SMC3 is running fine and fast so at the moment I leave it at that.

I must say so much work at least, sometimes so many problems and some of them not solved yet. But I am happy...video and much more will follow soon. The sim is working with LFS so far. No fine tuning, no special settings but it works as it is. Stay tuned.

That is a wonderfully clean and tidy setup. Very impressive!

Nice progress, check connections to the H Bridge and please use fan and heatsinks on them too, could be a connection issue or a heat issue, look for the simple things first. As well I would check the output of the pot, too make sure that is smooth too.
Another note is that due to manufacturing differences its not uncommon to have to use 2 different PID'S for 2 of the same motors.

I am totally unhappy and angry. Last week I got back the projector by vivitek. I was so glad to finish my work today, finishing all and installing the whole equipment. What a surprise while I was starting the projector - same issue as before, a greenish screen! What did they do the last 4 weeks? WTH I was waiting for one month and now nothing changed:-/ The projectors were the most expensive investment at all....now got back to vivitek support, will see what's next.

is there any color calibration in projectors menu? If there is an RGB balance option, try decreasing the green color and see if picture gets better?

Also, I assume all three projectors connected to your PC, can you see what color profile in windows is set for that green projector?
