MULTI TURN POTS

Will a 10 turn pot give you the same reading as a single turn pot using SMC3 utils? If so are they connected the same way? If I were to use a continuous turn pot (360 degree, hall), would that give me the same results as a single turn pot? I need to figure out which to use for a winch motor . At this time I get no reading using the 10 turn pot but it will work with a single turn or a three turn pot. I have tried (three) different 10 turn pot's.

hi!
multiturn is better if you use gears to use the full range of rotation. If direct drive, it will be worse.
Personnaly, i prefer simplier system (without gears) than more complex systems ;-)

Watch out: multiturn pots are often "wired" pots: this design are sometimes said as giving discontinuous values

these reference is precision wirewound pot:

thank you for the info. I am using gear clusters so will a 10 turn pot work with SMC3 utils? (can it be adjusted).
terry.

yes it will should still read 0 when on min and max when turned all the way, I have used them before on Jrk builds , cant see why an Ard should have any issues with them, actually they will provide a finer resolution to the motion , what I have found in the past with Jrks.

OK, now I know that a 10 turn pot should work with SMC3. The three "Cheap $5" pots that I have now will NOT work. are they connected the same, ie neg #1, pos. #3 and the wiper to #2? Can you recommend one that will work. I have a call in for the MW22B that Racingmat referred me to for the price.

Thank You

I ordered 2/ 10 turn,10 K pots of good quality and they work very well, as they should, however I seem to be having a problem with the travel range on my actuator levers, they will not go to the max or min range when running the FSX game. Also when I check them using SMC3 utils in sine wave position, they do the same thing. Any ideas why??

I'm not entirely sure I understand what you mean, however...

The SMC3 Utils sine wave test only drives the motors about 50% of maximum travel as can be seen on the chart. If you want to test to the limits you can select the manual mode and move the slider on the right of the chart to the position you want. Maximum is the top of the chart and minimum is the bottom of the chart.

Note that the Arduino SMC3 code will attempt to prevent the motors moving beyond the minimum and maximum clip limits that you have set (the red horizontal lines on the chart).

It does work that way, when I manually move the slider, it does go to it's min and max BUT when in the game(FSX) it will not and I maxed all my settings in the game and profile??

OK,

@terry wells if you have one motor for pitch and one motor for roll your profile is correct but if you are using two motors for pitch and roll then you have to do what @noorbeast told you

I have one motor for pitch and one for roll!

@terry wells if you put 100% instead of 70% in your profile do you have the desired motion?

Well here is what I did. I went into my tuning center and manually changed the force numbers in pitch and roll, they were 180 and -180, I changed them to 50 and -50 and all worked well. Both the pitch and roll went to it's min's and max's. Do you think the numbers are ok or do I need to change them somewhat?

Thank you all for all your help, I will keep working with this until I get it "PERFECT". Thanks again

Terry.

Well, bad news for me, went to get onto my motion platform and the break was not set so I screw up the pot control on one motor. Question? when is the break set to "ON" so one knows when he can step onto or off of the platform??? and If I were using "Continuous Turn Pot's would I have had this problem with going to far?? Do continuous pot's come in 10k or so??
