    I have 8 of these cards, I got them in the lot, a lot less of their price, you say you can not be connected in parallel as the moto-monster?

    For sure @SeatTime can not be connected in parallel mode... :) Could you please describe to us briefly what you mean? MMs can be used as a single driver or dual motor driver, SaberTooths do not support single driver configurations - 2x__ Sabertooths are only dual motor drivers.

    Were did I talk about connecting them in parallel? I know they are cheap, just like MMs and it took me allot of work to get sets of MMs to actually work - Your choice, your hair.

    about your boards disconnecting when you move fast the motors... i remmember that someone reported this error, and it was related to a lack of power in the psu... how many are you using?, maybe one psu per board

    or try to limit the amount of power each board takes.

    best regards

    Yes, for now I adjusted with the PWMmax 200, instead of 255, as I had done, and should be even better in very heavy shock never fall off.

    Finally completed everything:

    [​IMG]

    Many pieces printed in 3d, as a support potentiometers

    [​IMG]

    All electronics is placed under the seat:

    [​IMG]

    And of course, put an emergency stop button, to press for any problems.

    We catch up soon with 4dof project :D

    PS: i broke a motor of 2dof :( I think switch the 120W motors with 350W soon...

    New 350W motors arrived with the sabertooth 2x32A, will replace those 120W (will still be a 2dof, then in the future maybe I will turn it into 3dof by adding another 350W motor) bought by simukit (a special thanks to Wanegain, for many Info that gave me)

    [​IMG]

    [​IMG]

    I would use a 1200W 50A power supply I already had

    [​IMG]

    Mounted on the cockpit, they are solid!

    [​IMG]

    Printed gears for potentiometers

    [​IMG]

    [​IMG]

    And I also printed the cranks for motors, it's in PLA+ at 100% infill, weight 92gr one, I just hope they hold, otherwise I already have aluminum to do them, only I do not know where to find a 19mm drill bit to drill them XD

    [​IMG]

    Soon with the first tests :D

    Sweet lookin motor's....Where did those come from ? Looks like your perimeters are a touch fast or slightly under extruded.

    When Printing Solid Solid Objects you really want to ensure your actually getting 100% infill with a Big of Extra filament added.......jump up your retraction to deal with the potential zits and pimples if you dont have your retraction number's down pat.

    What filament ? PLA .....have you tried any PETG ? Its stupid strong filament, try it out on your next order.

    It's PLA+, I also noticed that gap, however at the moment they seem to be fine, I did some tests, I installed the code for smc3 on the Arduino, I find it very good

    https://www.xsimulator.net/communit...ket-serial-pid-motor-driver-w-softstart.9277/

    But the motors are too abrupt, they rush even in the slightest movements, I also tried connecting the potentiometers without reduced, so with 1:1 ratio, but it does not change anything. I think I have to add smoothing in smc3

    What's the gear ratio on those worm gears?

    A high Kd value helped me with the same problem. And Kp not so high, are good too.

    These are the motors, have a lot of torque!

    https://simukit.com/moteurs/8-moteur-350w.html

    I'm also trying with ks at 20, and it goes much better, I also have to try to increase kd

    Anyway, I think now I print gears for potentiometers with a ratio of 1:1, I find it better than with 2,5:1.
