If you mean the service tool from the teensy, yes.
Its on valtra/massey (1) and panda 115200 (p)

1257

what frame number are you controlling? cAD131C?
Can you steer the wheels in both directions?

1258

I am controlling CAC1C13. Directly from Tony’s code

When I activate the steering in AGO, the wheels turn to the center.

no matter where they were before.

1259

it’s no true!!!
frame ‘0xcac xx xx’ is frame back from PVED valve
controlling frame is ‘0xcad xx xx’. What frame number you controlling give me a full number (id).

1260

im sending 0x0CAD131C and receiving 0x0CAC1C13
in 0x0CAC1C13 im only receivig this data

D1 and D2 should be the current WAS.
D3 is the valve state.
correct?

1261

correct!
soo, it looks like something is wrong with the sensor or the wheel angle sensor wiring.
Check the voltage from the sensor. Maybe it’s broken!

1262

the dealer repaired it 4 months ago because the “speed steer” was not working because there was no was signal. now it has a was signal again, and the “speed steer” is working. the handler has calibrated the WAS

1263

Do you know where exactly I can measure the sensor?

1264

@CommonRail Tony wrote at the beginning of this thread

So then to steer the tractor, there is two simple steps:

  1. Tell everybody on the CAN-BUS you are the navigation controller and you are alive.
  2. Then send non stop at approx 40-80msec intervals the desired set curve, and if you intend to steer or not.

From there the steering controller (tractor) will the tell you (the navigation controller), What the desired set curve is, What the current curve (WAS) is, and if it is ready for steering commands or not (manual lockout etc).

Is it possible that I still have to do this “activation sequence”?

1265

hello @CommonRail in the HH menu

Ch1 and Ch2 should both be yes or only OSPE valve (YES)

if i have CH2 (nav controller present; to yes - getting error code 15993)

or should CH1 only be (yes - OSPE pressent)

1266

sensor is connected to the PVED.

1267

Does this mean that the sensor he replaced (in the axle) is not involved?

1268

i don’t know

1269

Hey, Does anyone have a all in one triple can pcb they want to sell i cant seem to find anywhere with all the right parts etc.
i am wanting to steer a fendt 924

1270

Where in the world are you?

1271

new zealand

1272

I can send anything you need, just send me a message.

Bonjour Commonrail, j’ai un Fendt 724 Profi + que je souhaite autoguidĂ© via le CAN, j’ai dĂ©jĂ  achetĂ© un PCB4,5 et je voudrai savoir quelle carte teensy 3 CAN acheter pour piloter mon tracteur ?
d’avance merci. Cordialement Phil

1275

PCB4.5 has a CANBUS on it already. Also, you should ask questions in English here, otherwise you assume someone else will translate it for you.

1276

How I can engage autosteer on massey 7624.
Everything else working fine. But tractor own headland button dont work. Can someone point me right direction.
