Hey Guy's
Can you give me some help? I included pictures.
I have a large robot platform with big 12v motors. An ez-b V3 Sabertooth 2 x 10
Here is my problem. I tried all the advice on the forums related to this topic. So far nothing has worked perfectly. The motors will turn, forward and reverse but will not stop in the movement panel. I tried every possible Dip Switch setting from Sabertooth. I feel the problem is that I do not know if the wires are connected properly from the ez-b to the Sabertooth. S1 Blue wire to ez-b D0 S2 Yellow wire to ez-b D1 On the Sabertooth, do I need to connect the 0V and 5V to the ez-b? If so which port?
Ah then I guess it powers off the motor power? Won't hurt to keep the +5 connected to ez-b though
Hi DJ
I changed it this way and it worked:
DIP Switchs 1 On 2 Off 3 Off 4 Off 5 Off 6 On S1 Yellow wire to White signal wire to EZ-B D0 S2 Yellow wire to White signal wire to EZ-B D0 0V to EZ-B D0 ground 5V to EZ-B D0 Positive
This configuration controls both motors in the Sabertooth panel. It also powers the EZ-B board. The motors are at full speed. I would like to slow them down or use ramping. Is there a way to do this?
I included pictures so that the next person may not be as frustrated. Please disregard the one motor wire that came out while moving the board. Thanks
Hi Guy's
Everything I read said not to connect the positive to the EZ-B. It did not work that way. So the Sabertooth powers the EZ-B with +5V at digital Port D0. I am using a small 12V 5.4ah battery for testing. I will need something with a higher amp hour rating for the robot. It currently is all aluminum with large motors and chain drive. It is 32 pounds right now, but will be about 75 pounds completed.
I am concerned that a larger battery will send to many amps back to the EZ-B. And the powered at 5V will not provide anough for sensors etc.
Maybe I should go with a different setup like: Sabertooth 2x25 or PhidgetMotorControl HC
Hi Moses58.
How did you end up hooking up the Sabertooth?
I think I understand it better-- a digitial port goes to S1 (and another to S2 (?)). Can the Sabertooth's ground go to any digital port's black lead? There are a few places on the EZ-b board that seem to take ground wires.
Also, did you end up powering the EZ-b with the Sabertooths 5V output or use a spearate power source? I see that 7.2 V is recommended in the EZ b manual.
thanks,
Frank
Hi Frank
There is not much information on other motor controllers with EZ-B.
Yes the EZ-B is powered by the motor controller.
I kind of gave up on the robot plateform.
It did not respond to speed control.
The motors are very large.
The robot is very heavy.
Could cause damadge or injury if it got away
Thanks
Moses
