    hello group, a year ago I created a 2 dof, which I have enjoyed a lot, now I am creating a 3 dof which I really want and enthusiasm, I want to share my experience with all of you.

    Hello, I have a problem with the third motor, I'm in smc3, the first two motors move perfectly but the third motor only moves a little to one side and there it stops and no longer responds, could it be the source? or rather a matter of parameters, I'll give you an image of my configuration in smc3, the motors are wheelchair 24v 75rpm 250w

    If you swap the pots controlling positional feedback between motors, does the issue follow or not?

    Thanks for your answer, I haven't tried that, this afternoon when I get home from work I'll try and tell you, thanks.

    Hello, I checked what you told me and it's still the same, the motor does turn but only to one side and then I can't make it come back

    Can you please post a SMC3 picture after the change.

    I have already solved it, the problem was in the wiring, I had mistakenly put a cable where it should not have, thanks

    hello, after solving the problem I had, I mounted the seat on the structure and began to do the first movement tests, then I find that it is very unstable, it has a lot of play and I think it is because the motors are too far forward. Do you recommend putting the motors as close to the cardan as possible?

    What are you using for the universal joint?

    If there is play best to work out where it is from.

    Moving motors closer to the pivot point also means they have to be able to produce enough torque, as the closer you get the more torque required.

    that's what i'm using, i think the motors are strong enough to be in a wheelchair, what do you think? a lot of separation and exerting little force near the cardan.

    Lo tengo casi terminado, ayer hice algunas pruebas, hay que ajustar algo, pero estoy muy contento con él.

    I would like to know how I can limit the axes in simtools, you can see it in some section of the manual. or I can see it in some section of simtools, within the application

    There is SimTools Axis Limiting in the interface, but in my view in most cases axis range should be defined by the control hardware/software.
