    Sorry for the stupid question, but for what reason there is no firmware for 4dof, for arduino uno with ibt-2 drivers?

    An Arduino with SMC3 can only handle 3 motors at 4096 PID updates per second, but you can use multiple Arduinos to control 4 or more motors.

    And why has no one tried to use stm32? And as one
    arduino working in 4dof mode with h-bridges sabertooth?

    I understood. Then one question remains why no one has yet come up with the 4dof-6dof firmware on stm32, because it is more powerful than arduino and has more outputs. Or simtools can only work with arduino libraries? Personally, my opinion is that it’s not very convenient to still use 2-3 arduino to control more than 3 motors ..

    Existing code and solutions remain popular for budget projects. For more complex projects, 4-6DOF most have moved on to AASD15servos and controllers that can do 6DOF (rotary or actuator), plus make using the servos almost plug and play: https://www.xsimulator.net/community/faq/amc-aasd15a-servo-controller.351/

    Thanks for answers. Alas, for my country (Ukraine) AASD15 is too expensive and it is very difficult to order them from abroad..

    Hi @RufusDufus, Can I ask a question, why is this project source code not updated with the latest version on GitHub? Thanks.

    @RufusDufus has not been active since Oct 17, 2021, so it may be a while before you get a response.

    Thank you for your quick reply, I have checked GitHub and the last update is 5 years ago version 0.7 but here on this topic, the latest version is 1.1.

    hi i have a small problem, and i hope some1 else also had the same before.
    i build myself a 2dof platform.
    everything works as it should, exept i used 360degrees hall censors instead of 180 degrees.
    The reason was that i couldn`t find any 180 degrees they where all sold out.

    the problem that i face now is that the motor goes outside of the limit`s that i setup, because the range is not the same as the 180 degrees.

    currently i have it setup so that the hall censor reads 500 when the motor is in the center position,
    but when i move the motor to the upmost position the censor will only read 750 value and not the 1000 that hits the limit.

    Is there a way for scaling in the software wich i can change in the code so that the censor will obey the motor limits?

    You can always gear a pot, but the way you describe this it sounds like the SMC3 settings need to be redone, when using a 360 Hall sensor you will lose some resolution but its tracking should be accurate.

    the sensor is mounted straigth to the motor in paralel with a flexibel tube. it follows the motor exactly.
    i have reset the software and reuploaded the basic software.

    it loads up the way it should but if my motors are both up to the maximum the green line will be halfway between the red and the blue line (because the sensor is also only halfway open)
