I’m building an RC lawnmower using 2 Jazzy wheelchair motors powered with 24 v (two 12 v lead acid batteries). I’m using a Sabertooth 2x32 motor controller and a FlySky FS-CT6B transmitter/receiver. I have channel 1 (left/right) on the receiver wired to S2 on the controller. Channel 2 (forward/reverse) is wired to S1. I’m getting the forward/reverse motion on the motors, but no left/right motion. I’ve performed diagnostics on the controller using DEScribe software and see no signal to S2. I’ve changed to servo wires and have tried switching the transmitter/receiver to channels 3 & 4 and get the same result. Before I send the controller back to Dimension Engineering, can anyone tell me if I’m overlooking something? Seems to me that this should be a simple setup.
You need to set the DIP switches correctly on the Sabertooth itself to enable mixing. Be sure of every DIP switch setting. You should not need to change any software.
Thanks for the reply. I’ve got the dip switches set for RC as directed - #1 off, all others (incl. mixed) on. I’m assuming I should see opposite directions on the motors in response to a left/right servo movement (channel 1). But I get no response at all. I’m assuming the controller is bad. Do you agree?
There are ways to figure that out. Take a look at the DIP wizard here: dimensionengineering.com/da … DIPWizard/
Normal RC -> radio control -> battery -> mixing -> linear control -> radio transmitter
Gives: #1 and #3 down
Thanks again for the quick reply. I’ll try the dip switch settings you suggest.
At the same time, check that the Sabertooth is wired correctly to the receiver, with two servo cables.
Both red wires go to 5V, both black wires go to GND (0V), and each of the signal wires go to S1 and S2. The receiver should not be powered separately.
Check that all wires are properly inserted and have contact with the terminals.
Will do.
Kena…Just finished mine using the same equipment. I have the schematic I drew up with the DIP settings too. Let me see if I can figure out how to post it!
I was able to post the schematic on my post. Look at Remote Control Lawn Mower.
Hello from Germany, I also use a Sabertooth 2x32 driver.
the driving mode works beautiful but I dont understand the user modes. I will make á funktion, that stops both motors if a sensor recognizes a abstacle.
the sensor gives a 5V signal and this signal I give to an Input into the sabertooth, but I dont understand how to setup a user mode diagram in describe software
Apologies for the late reply @coolkuh hopefullly you found the answer, but creating a circuit which can provide the appropriate signal to the Sabertooth isn’t as easy as programming an inexpensive microcontroller which can act as intermediary between the sensor and the Sabertooth.
that must be thought transference.
I haven’t continued working on the project since 2018 and just 2 days ago when I was cleaning up I saw the vehicle standing there and now I have reactivated the two batteries that were now deeply discharged.
In general I will use the Sabertooth again but I no longer need the function from back then.
I have to get completely familiar with the subject matter again.
Indeed, and there were a LOT of other thoughts I had to ignore which were not related 
Hello again
Now I’m hooked on the old project with the Sabertooth driver again.
Unfortunately, the help in the describe software is not as comprehensive as one would hope.
I need some information, a tutorial or video on how to edit these user modes and what you can do with them.
Could someone help me with this?
Thank you
Oh sorry - I didn’t write that at all - it’s about the describe software ;o)
I don’t understand these user modes.
How do I handle and edit them?
Hmm… still not sure which software you mean (for which product?). Can you provide a link to the software’s download page?
To confirm, you have a Kangaroo board connected to either the Sabertooth or SyRen motor controlller?
If not, then you really only need to care about the motor controller’s configuration.
Oh okay.
Then I find all the settings I need. I connected the motors directly to the Sabertooth
Thank you
