Hi All, I am trying to use a prescription weed map in a Trimble gfx 750 running Precision IQ and latest version firmware14.6.
The only way the prescription performs correctly with the trimble rate and section control is if i use the magic tool in reverse.
Example…
No spray on weed Zone.
80L/Ha on NO weed Zone.
This will apply correctly unless the prescription has a donut shape or polgon around an application area then the map will not turn on the sections as required in the centre of the donut.
larger zones with NO donut shaped application maps will work.
I did try just reversing the rates on the application zones before exporting and the prescription would not section control or rate control at all.
Single zone prescription have not worked in PIQ,
Any Trimble settings or advice in exporting from PIX4D fields would be great.
The PIX4D field process in generating the maps has been great.
Thanks
Tim
Hi,
did you try to create a prescription map that has no zone for the 0 rates and also no 0-rate zones?
Like this:
Based on info from trimble you should have an option though to treat 0-rate zones:
“For the current display generation (GFX350, 1060, 1260) as well as the GFX750, it is possible with the current software versions (from PiQ 14.60 onwards) to activate a function in the settings that allows the creation of exclusion zones from application zones with zero rates.”
Also did you checkthat you have the VRA unlock?
Thankyou for your reply
All the the trimble settings seem correct and aslo have a valid prescription unlock.
All the maps I have ingored Zero rate geometry.
. The latest firmware 14.6 is a test pilot program and test pilot needs to be activated to change application control preferences.
thankyou for your help.
would be great to here from anyone using trimble prescriptions and PIX4D for a work flow.
Thanks Julius
Hi,
If you paid for the VRA module, they should tell you what prescriptions to use. Hopefully you can escalate it.
What if you add a very small amount of liquid instead of 0? can you try with 0,1?
Feel free to share your prescription, we can send a prescription to test if it works.
The latest, the screen has a valid prescription unlock ( i use the same screen for VR spreading)
tried a map at low rate 1L in the zero zone sections all stay ON.
The best i can do Red zone 0L/Ha. Green Zone 80L/Ha
the map will work becuse all of the green zone are connected or one area. section will NOT turn on inside the yellow circle.
Thanks
Hi,
please share it with us, we will share another file to see if it works
Can you also share with us the exact Implement & Brand you are spraying with. It might also be a limitation of the actual spraying hardware that you use.

Testing on Trimble GFX 750 runing PIQ. Sprayer is a tow behind JTA with trimble FieldIQ controller
I also have a millier nitro 7380 with Trimble GFX750 runing raven spray controller. it does not have the prescription map unlock so i havent test on it.
Thanks, it seems you mixed the files, the .prj belongs to a different file.
