    I believe at least two reads will be required. My feeling is that something (transistor gate at analog input?) needs time to properly charge and sending multiple reads provides this time.

    Here it is: SMC3 with MODE 4 added to support Sabertooth packet serial (I marked my changes with "//GB:" - "//:GB" tags) and regular unmodified Sabertooth library.

    Nice work, the Sabretooth drivers seem to be growing in popularity.

    @RufusDufus,

    could you please confirm that the input declarations I posted at #1057 could be used for a 2DOF setup? The goal is to simplify the connection between arduino and MM via piggybacking of the two

    thanx!

    @outrunner, I don't think it will be as straight forward as that. I had to bypass standard arduino libraries in a number of places and changing pins may affect other timers and things - it's been a while since I looked closely at the code though.

    You're welcome to give it a try though - it will either work or it won't.

    EDIT: To answer your question in post 1057 why it wasn't written to work as piggy back - simply because the MM wasn't the first driver it was developed for so it was just configured to use the pins already setup for other drivers. :)

    hello guys, I put those two videos made smc3utility, I would like to know from you what would you change these settings or if all goes well.

    i has replace my potentiometers with new hall effect pot. and i have some problem to make it reverse. i have change the motor wire (from monster shield to motor) but it still move incorrectly, did it can change some code for make it reverse ? @RufusDufus

    @luky_90 increase the PWMmax as far as you can until green line follows blue line as close as possible... as long as motor and driver can handle without overheating.

    What you have done is so far correct and it should have changed the direction of the motor. Don't! swap the PSU connections to the Monster shield. Do you have 5V and ground going to the right pins on the hall effect pot, it won't work if they are incorrect?

    Hi All!

    Can anybody send me the correct Simtools interface setup for the current version of smc3?
    Or any link where I can download the presets for simtools?

    Thanx,
    George

    Simtools Setup

    Setup for Simtools is very straight forward:

    [A<Axis1>][B<Axis2>][C<Axis3>]

    Set for 10bit binary output

    Baud rate 500000 , N , 8 , 1 (10ms delay)

    That looks correct to me. As long as you have the proper com port it should be good.:thumbs
