Butterfield, MN | Envizio Pro with SwitchPro, assuming the software on both is up to date (E-Pro certainly is), 1000 would be the speed cal number I'd use, since it should be using GPS speed, which is generally very accurate. If the SwitchPro is not up to date, it will ignore the 1000 speed cal and continue to bring in speed from an external sensor, if that's present. I think the most up to date SwitchPro software is 1.70 or 1.80. Either of those versions would be new enough to use GPS speed over CAN.
If the SwitchPro software is new enough, speed should be accurate, and the width entered in should be accurate, I'd start to think outside of the box. I don't ever remember seeing this issue on an Envizio Pro with internal GPS before, but I do remember seeing an issue with old Phoenix 300 receivers where the elevation was way off. If you think about how this system knows that it's mapping on the face of the earth, which is nearly spherical, it can happen where the elevation it figures out is miles below or above the surface of the ground. When that happens, it has the effect of making it so your guidance lines end up being too close together or too far apart, making a decent overlap or skip as you apply back and forth. You could test this theory by dragging a chain on the ground at the center point of the machine, turn around and drive back next to it on the next swath. Then measure the distance between the two lines that the chain drug and see if it measures out correctly for to the swath width you have entered in. If it doesn't, I'm not really sure what to do. I don't think the software on those internal receivers can be updated, so if it is using the internal receiver, the only idea I'd have is to try connecting up to a different external receiver and set up the outputs correctly to work with this system (GGA, VTG, ZDA at 10 Hz). | |

Raven Envizio Pro over applying solution.
