Long term reader of the canbus topic but havent ever contributed, so here goes!
I have been working on connecting to a Claas Lexion 760 via canbus for steering. The steering seems to be similar to the Claas tractor CAN profile but slightly diffrent.
Originally the steering angle on the tractor profile is read from 0CAC1E13 but on the combine seems to be replicated on 0CA1C13, It doesnt have the same range of values as the tractor but this is easily fixed.
My problems come when trying to work out what is needing to be sent back to the combine for steering, which ID should I be using and or how do I work this out?
Okay,getting back to this.
Went through the instructions above and no change.
The steering switch is on and lit up and the quick steer is working so presumably power to the valve.
Connected the teensy via usb and opened serial monitor and have the following.
In the data of that screen shot see the 3rd data number is 61, that must be 16 before anything can happen. Try working through that list above when looking at this number and see if it changes.
Anyhow I now have Autosteer working!
With Agopen set to button and easysteer engaged the button on the pcb engages auto steer.
The tractor armrest button doesn’t engage auto steer but lights up when engaged and will disengage when pressed.
Any steering wheel movement also disengages.
Didn’t try to engage through headland management which I believe has worked for some but what are other options?
Okay thanks for all the help and advice, I will probably use the tablet button to get setup and started then look into getting the armrest button working in the winter when I have a bit more time.
Out at the dealers today, we got nowhere with this. Tried all 3 buses on x16g, especially wkbus, and no steer codes to match the INO at all. Even using the flow view in savvycan, nothing looked like a WAS. This was with the valve engaged BTW, and even with it steering in the factory SBAS autosteer.
Thanks, we did pretty much the same. The one I was in was the one with all the screens, command joystick, etc. The steer valve, I believe, is enabled on the arm and this brings up a screenshot full of options, one of which us a steer box you have to tick, and autosteer-engage button is beside it. As this one was steer equipped, there’s an auto-steer option on the monitor too that brings up your fields etc but I presume that wouldn’t be there unless unlocked.
So, it had all the toys, but no sign of the AC/AD drive codes. Full captures at the link above. Going to try a T.175 tmrw to see if thats any different.
Hello,
I would like to equip a maxxum case from 2017 with agopengps. here are some photos of the steering solenoid valve and connectors.
Do you think I can do a canbus assembly?
