SMC3 Sabretooth TEST version

why use 2 or more Arduino when you can on one Arduino + 2 Sabertooth 2x32, and more even 8 pieces.
I found a solution for 4dof here https://www.xsimulator.net/communit...ket-serial-pid-motor-driver-w-softstart.9277/
but only had to fix the code for 4dof.
all thanks! sorry for my English

You'll have to do more than just add motors to the sketch if you want it to run properly. Your smart move would be to go with the sketch noorbeast suggested or to use two arduinos but suit yourself.

must easier and better with 2 uno's

Good luck. I don't see the point, anyway each to his own. If you should have successfully coded a working scetch honestly let us know.

Everything works fine. To connect 2 Sabertooth 2x32 need, In packet serial mode, DIP switch 5 sets the packet serial address. The ON position sets address 128, and the OFF position sets the address to a user-definable alternate 129.
In SMC3 sketch uncomment the line 1549-1585 for 3 motor work.

From the thread you have quoted: "UPDATE Beta5 to Beta 6 on Nov 12, 2016 - commented out motor3 to optimize serial execution speed and because it likely won't be used anyway since only one motor channel on a second sabertooth can be used.

Anyway let us know if you got 4 motors or more working with just one Ard. We are here because we never give up

Hi.
connected yesterday 3 of the motor. everything works fine.
1 Arduino uno and 2 Sabertooth 2x32. 13 pin for Sabertooth 1 (address 128) for motor (1,2) and 13 pin for Sabertooth 2 (address 129) for motor (3). DEscribe 115200.
in the sketch Sabertooth ST[2] = { Sabertooth(128, mySerial), Sabertooth(129, mySerial), };
simtools work fine [A<Axis1>][B<Axis2>][C<Axis3>] Baud rate 500000

Yes I use SimTools 1.3

Did you ever stop and ask yourself why someone would make the effort to add the necessary code for a third motor only to comment it out? Does it work, yes. Does it work fine, only if you don't mind signal clipping.
Most people that can afford to build a rig can afford one more uno too in order to gain additional processing power but again suit yourself.

Ok. I also have SimTools 2.0 Pro. I use both versions.
as the simulator will be ready, I will show the video

fine, but then open a new thread in the appropriate forum. Thanks.

I wrote a sketch which can drive 3 Sabertooth 2x32 (6 motors) on one Arduino. As they are communicating using serial, it's not a big deal to have up to 6 motors on one Arduino (not Uno because I always keep an analog input to set the global power of motions).

That's great but were talking specifically about the SMC3 sabertooth sketches. I agree though its no problem driving 6 motors with an arduino . In fact you can drive up to 48 motors from a Mega if you want to but it all depends on how robust the PID control is and therefore how much time it takes to execute for each motor.

Does this Version also works in Mode 2? I Just cloned my sabertooth setting arduino but want the additional Operate in Mode 2 with the cheap Motor driver
