This number?
I will watch it closer when I hook it up
I took this video as a summary of the settings. I will be the first to admit that most of it is just a guess on my part.
One other question is I have the spark fun sensor that’s on the parts list for the pcb, am I wrong in thinking that’s for roll? What do I set that as, cuz anything I have tried hasn’t worked.
Open to any suggestions
You don’t have any correction at nmea(gps) input? You should use at least egnos.
And it’s 1hz. It should be set at least at 5hz.
What gps are you using?
I am using the arduinosimplertk2b
But don’t have the sec gps for rtk yet.
Could you try to increase “lowmax rpm” at 60-90
You should also check how much you can pump up min pwm , take a look at the excel file Math made.
Like @Kaupoi said it seem that your receiver is at 1hz, that make also your wheel sensor update only once per second, you will not have good performance with these settings.
So since you are using an SimpleRTK2B the first step is to update to firmware 1.13 and configure it the output at 10 hz.
here for the steps to update the firmware
here to see how loading configuration files or changing settings yourself.
There are configuration files available on this forum, search for 1.13.
Personally I always change it manually, I have a list of changes to make for rover and base.
Be sure SBAS is enable in v1.13 if you are not RTK
what if it will have RTK some times? I plane on using a base station when im planting, but not for spraying or tillage, do i still enable SBAS?
Thanks for the help.
you can keep SBAS evry time for the rover
if you make your base you need to removed the SBAS
Hey Mueller.
Tried the same gears for the steering wheel / motor on our jd 6r.
Looking at the videos above, sounds a bit noisy.
My experience was that the 3d printed gear wont hold up against the metal gear.
May be a good start to get going but looking at it closer, the teeth are not real gear-teeth.
Redesigned it in straight spur gears. Not perfect, but waaay smother. May be helpfull.
Good work, keep it up.
Greetings.
Hi Lui
Thanks for the tip,
it is noisy in the video, I still need to do some work making the bracket sturdier, Im hoping that will help.
did you print that motor gear on the original design part with pla or with a flexible material like tpu? I used sainsmart TPU and in my experience it is quite strong and durable. But I need more time for testing.
what material did you use on your design? how many perimeter layers and infill %?
Looks good.
Tried the original design in petg.
Maybe should have givin it a go with tpu…
Printed my redesign in petg aswell. 100% infill, 0.2mm layer heigth.

Nice concept to adapt gear, could you share it on steerring mount files ? John Deere
as information
The Tpu is like rubber i it is very soft and strong very hard to grind, wear .
The combination of steel and TPU is not noisy and the small teeth is to catch a small adherence but the most important it to make pressure like friction type concept to do like tyre on the road
as example , this summer a video on the cab you can ear the noise of PWM to electric motor and steering rotation and sorry but the noise of suspention seat (7000hr) is boring
Wow ok. Really missed the point of it, sorry.
Will post in thread for steering mount files.
Also will give it another go with tpu on other JDs here on the farm.
Cheers.
Update ;
The aluminum gear didn’t hold up, so I printed the gears that lui shared with us. Thanks for that!
I printed and mounted the surface in the corner and I have a wireless keyboard and mouse.
Questions ;
When it’s driving straight it seems to have 6-10 or so inches of “play” I’m not sure if the gps or the steer setting are the reason. Possibly a bit of both.
Right now I’m using the arduinosimplertk2b with no correction, but did enable sbas.
Now I just need to spend some time cleaning with the wiring and probably move onto the next tractor and make a base station.
Looks good.
Had a similar issue.
Checked the WAS values, if 0° is actually about 0°ish. By driving straight in manual mode.
Checked the values for antenna position in aog.
Checked the values for Minimum PWM and Low Max PWM. So the system is able to correct small errors.
What brought in the most peace was placing the antenne a bit forward in the end.
Using the dual gps with the code from @MTZ8302 it is easy let the esp32 calculate the antenna position ahaead of the physical position.
Not sure if this is the correct way of doing it, but may help.
This is most likely i willl look into it.
I have heard alot about the dual antenna, but im not clear on what the main advantages are?
more accuracy? does it calculate roll? I’m just not clear what makes it worth the extra time/money/setup
I can’t move the gps much farther ahead. Lol
Thought I would take some pictures of the install, might help someone else along the way.
I really like the breaded wire loom, it really makes the job look more professional.
Maybe some one can rename this thread, 6125r install.
As it ended up being a summary of the problems and answers I had along the way.
