So this is a head scratcher one for me. I am still using ARC 2020.01.05.00 first off. Im trying to get the robots drive system to make left or right turns, but I can only do forward and reverse. I have a EZB-V4, I have a SSC32 to the EZB. Ive tried a DE 2x12RC motor controller and then a Sabertooth 2x15 motor controller. Both exhibit the same results. On the SSC32 I have setup V14 for F/R and V18 for L/R. Here is where it really gets wierd.... when in the test setup mode of the Continueus Movement panel,when i click on the verious test buttons, I can get the proper motor directions, but once I save it and go to use the movement panel, I can get only forward or reverse, no matter which of the four directional buttons i click on. And the real topper.... Ive tried both motor controllers hooked up to a 3 channel RC car system and all directions work perfectly fine. So has anyone dealt with this same issue? Ive used the movement pannel on other robots and never seen this happen before.
So last night I ordered a new Sabertooth, the 2x12A non RC version. Decided it would be best than trying to get the RC version to work which still wasn't happening for me. So will see what happens next
So my newer Sabertooth 2x12 motor controller arrived today. I must say, I am Not impressed with how it works. It pretty much worked like the 2x12RC version. I am using the sabertooth control function, connected to D0, and configured it for 9600, per DE spec sheet. What I found is that whether I am clicking on the arrows or using the speech req, it gives the same results....the two drive motors will sometimes move in sync, sometimes move independent, sometimes ony one side moves. When I go to adjust the sliders, the motors go from slow to fast or the motors will change direction. Sometimes the stop won't work and i have click on the release button to get them to stop. I have had this same result with 9600,38.4k,or 19.2 baud rates also. Also , are there no other controls to adjust in the Sabertooth control?
@RoboHappy..... You are not impressed because you either don't understand how it works or you don't have it set up properly.... I have a few non-RC version 2 x 5s and a few 2 x 12s and they all work brilliantly for me.... ARC is flexible so if you can't figure out how the sabertooth movement control works then simple use the custom Movement Panel and write your own...
@DK- I do understand how it works, that is why I am not happy that it is not working correctly for me. I also went back to the servo movement panel( thats the custom one correct?) and could not get anything to operate stable. I did discover that the 38.4k baud setting seemed to work just a little better, but was still not perfect. Maybe you could show me what you do to get yours to work?, I am baffled with this, it should be easy. I had better luck with those Parallax HB25's way back, which are not made anymore. I do like the Sabertooth, so I really want to get this going, its holding up my big project right now. FYI- I am not using ARC yet, still want to use ARC first.
The servo Movement Panel is not the custom movement panel... The Custom Movement Panel is the Custom Movement script under Scripting... It's a separate control... This is very simple to figure out.... Read the sabertooth manual.... that's how I figured it out... Learn how (and what) to send serial commands (Under the custom movement script)... I won't do this for you or anyone else but I am happy to point you in the right direction. I figured this out myself so you can too.... Besides you will learn and understand a lot more if you do it yourself....
Why is anyone using the custom Movement Panel for the sabertooth? Does the sabertooth control not work well enough?
Yes the built in sabertooth panel works well (last time I used it, anyway). However I personally use the custom Movement Panel because I fully understand the sabertooth and I can fully customize my robot's movement abilities as needed.... Speed control, speed ramping et al....
I was hoping for a more plug n play approach, and no the regular Movement Panel does not appear to work with my sabertooth (hence the reason for this thread in the first place).
