Is there already a posibility/configuration/setting to mark a larger area in the back of the vehicle in manual mode, not only the narrow band of the sprayer?

Yes, I made the section/tool thicker in order to see it better. Also added an additional color along side of the sections for a different color as a maker for what could be overspray or wind drift. Variable rate can pick this up and adjust if needed. Once you get the glcolor and glvertex figured out, you can draw what ever you want from a reference of the patch list. A trailing disk has some more math that gets fairly complicated but Brian already has the trailing tank and trailing tool built in. Should not be too bad.

Good luck @richardklasens

Been trying to reply to your private message but looks like you have it disabled.

To answer your question re how I've been bypassing the orbital.

To make sure the valve works I completely removed the orbital from the system. In my attempts to get the two running together I've simply been T'ing off all the ports. The valve would make the wheels slightly twitch but that was it.

I'm looking at getting a SV10-34 valve to incorporate with my SV10-57C. The SV10-34 has 3 ports. By default (de-energised) it allows flow from port 1 (pump) to port 2 (orbital) and when energised allows flow from port 1 to port 3 (SV10-57C). This should solve my problem as the oil will no longer be able to flow back through the open centre of the orbital.

I don't think I have power beyond on my tractor- it is old (1984 Massey Ferguson 2640).

Nice tractor! I like these bastards!

In my tractor (Massey Ferguson 6160) your solution would’nt work because i need oil flow from the orbitrol to the transmission Low pressure circuit. As @LarsVest has mentioned, i’ll create a extra T-line directly to the tank from the steering valve. The T-line from the orbitrol goes to a pressure reduce valve back to 17bar, so in my opinion when steering on GPS, the oil flow in the valve should be enough (oil take the path of the least resistance) for autosteering. I’ll post some pictures when finished. Thanks for your answer, will be happy to see some shots from your setup!

I am not sure about your hydraulic system ArBe but I think your tractor uses a hydraulic double pump that could look like the one I have attached.

So when you block the oilflow with the SV10-57C, then the oil can only pass trough the security pressure relief valve (must be somewhere on the line from pump to orbitrol but probably direct after pump or in the flange that bolts to the pump) at the max bar setpoint (could be 180 bar) and that generates heat in the oil.

You could put in an adjustment valve before the orbitrol and block the line partly to your wanted/necessary pressure to move your wheels.

Or get a unloading relief valve (princip is given here Hydraulics Unloading Valve Basic Principle and Symbol | Hydraulic Valve) the valve could connect to your inlet port on SV10-57C and then call for pressure when needed or else let all oil pass freely to orbitrol

Maybe this one could work https://www.hydraforce.com/Pressure/Pre-pdf/6-170-1.pdf

@LarsVest.

Let's see if I understand this correctly.

I would place a T in the pump line going to the Orbital. The T would take a feed from the Pump and feed the SV10-57C and port 1 of the RV10-28. Port 2 would go to the Orbital.

As the SV10-57 is closed centre the oil flow would be blocked by default building pressure which opens the relief valve causing oil to flow to the Orbital. When the SV10-57C calls for oil the relief valve closes and oil flows through the SV10-57C.

Edit: Have attached a simple pic showing possible plumbing configuration.

The pic is correct, this way the pressure can be set as low as possible to reduce the heat generated in the system, (but still enough pressure to move wheels)

It seems that I can´t find the correct valve to make the better (more complex system but with free flow to orbital) you see in fig. 3.15 in the earlier link.
Perhaps someone has the name of the right valve. This one is maybe ok PD10-34 with 170 psi bias spring https://www.savery.co.uk/products/hydraforce/selector/PD10-34-3B-N-170

Then you have to add a non return valve on the line to SV10-57 and another T to feed the pilot port of PD10-34
You should also add a small pressure reservoir to maintain steady pressure on pilot line for a little longer when SV10-57 is not in use ( It compensates for the leakage in the system )

So use the RV10-28 or the CB10-30 or both?
Click to expand...
Only one of them. the simplest way is RV10-28

Edit: I think CB10-30 should be replaced with PD10-34 with 170 psi bias spring, like this: https://www.savery.co.uk/products/hydraforce/selector/PD10-34-3B-N-170 But I still hope someone can enlighten us, because I have seen one like it used in a system from one of the other autosteering companies, but cant´t find it again.

More info to ArBe 10. aug 19: While harvesting rye grain with my JD 1075 from 86 I had time to think about your system:
You maybe already have a electric on/off valve to shift between orbitrol and proportional valve, so keep using it, to only block oil to orbitrol when autosteer is on. The excess oil (when using autosteer) from RV10-28 should be T-ed back to orbitrol
OR replace both RV10-28 and on/off valve with this one, it combines the two https://www.savery.co.uk/products/hydraforce/selector/SVRV10-26C-4B-N-12DS

thank you kent_stuff.
I will continue trying to modify the vehicle settings and the programm. Need some time get more familiar with c#. Do you have a github repository for your modified code?
Click to expand...

When I started working on this in the spring, I did not even know what C# was, or how to edit it. Last programing I did was in Fortran. I don't know if they even make Fortran any more. Big learning curve. Studied Brian's work and made small changes to see what each did. Lot's of errors. Wife says, "Can you call them and ask them?" I just laughed. No, I do not have a github for the code. I'll try to paste some of the edits here or attach a file.

Good evening, i would like to use ESP32 with the cofeetrac sketch but any time i try to send data from esp32 to AOG using UDP i get nothing. Mine esp32 is in the same network of my computer i disabled firewall but nothing, AOG says "ops NC". Any solution?
 
#3,934 ·
You might want to run a program to monitor network traffic, such as wireshark, to determine if your tablet is seeing the UDP packets from the ESP32. You would run wireshark while running AOG. There will likely be a lot of traffic you're not interested in so you could apply a filter like "host x.x.x.x" where x.x.x.x is the IP address of your ESP32.

Hi,


I'am looking in the actual version of AOG for the steering wizard.
Has it been removed?

yes.

just have a look at steer actual at the main window. and make settings according what you see. (steer to the left shoult be negative)
 
#3,940 · (Edited)
Correct. Inside it's just a motor. Probably has a position/speed encoder too. The electronics inside will be less useful unless you can figure out the interface, but the motor itself is just a motor, and any other sensors inside are just sensors (analog or digital). It might even have a PWM motor driver you can interface with. Post pics of the guts of it when you take it apart.
