Survey won't record, or the design comes out wrong

No RTK Fixed yet Most likely

Check: The card reads GPS: FLOAT (or DGPS, GPS), or RTK: Unstable.

Fix: Wait for RTK Fixed. If it doesn't come, see Stuck on Float.

The receiver reports RTK as DGPS

Check: An amber line under START SURVEY says RTK Filter is ON and this receiver reports DGPS. Turn off RTK Filter (Settings > Survey) to survey with it. Tap here to open Settings.

Fix: Only for receivers that label a true RTK fix as DGPS (John Deere StarFire SF-RTK): see DGPS instead of RTK.

No GPS, or the feed stopped

Check: The card shows GPS: STALE — position not updating or GPS position has not updated for Ns. Check the receiver, or drive a few feet.

Fix: See No GPS in the app.

Field Survey or Levee: no benchmark yet

Check: A window says Drop a benchmark first.

Fix:

1. Park on something you can find again, such as a gate corner or a culvert end.
2. Tap Drop Benchmark Here, the green button at the bottom right of the window.
3. Keep the machine still while it averages (5 seconds).
4. Tap Start in the sidebar.

The fix dropped below RTK Fixed Most likely

Check: The GPS badge isn't a green RTK any more. The RTK Filter paused logging; it starts again by itself when the fix is steady.

Fix:

1. Stop, or slow right down, and wait for the badge to turn green RTK.
2. Check the base and the correction link.
3. Keep away from trees and buildings while surveying.

You're driving slower than the recording interval

Check: Points come slowly when you crawl. Recording Interval (first row of the SURVEY box in Settings, default 10 ft) is the minimum distance between points.

Fix: Keep moving, or shorten Recording Interval: tap the number on its row and type a smaller one (1 ft at least).

RTK dropped on those stretches

Check: The gaps line up with where the GPS badge left green.

Fix: Drive back over them with RTK Fixed. In route surveys, short gaps are joined with a straight dashed line; check the dashed stretch looks right on the profile before designing.

Not enough points

Fix: A field survey needs at least 10 points. Tap Start and keep driving. Or tap Cancel to leave without saving.

Leaving would lose the survey

Check: The app says Finish field survey first, or asks Discard N unsaved points? when you tap Cancel.

Fix: Tap Finish & Save (or Stop) to keep the survey. Cancel never saves.

The save itself failed

Check: The app says Save failed: … (route survey) or Failed to save survey to disk (Levee).

Fix: Tap Save again. If it still fails, check free storage and the storage permission: see Files won't save.

The survey has fewer than 2 points Most likely

Check: Read Points, the second number in the bar across the top of the survey screen.

Fix: Record a longer survey. Or tap Load in the sidebar and pick a saved one.

The RTK Filter dropped every point

Check: Points stayed at 0 while you drove.

Fix: See points aren't logged.

Depth Offset is negative or wrong Most likely

Check:

1. Open the design window: tap Slope-IQ in the sidebar of the survey screen.
2. Read DEPTH OFFSET, the first card along the bottom of the window.

1

Fix:

1. Tap + under DEPTH OFFSET until the value is right, or tap the number and type it.
2. Look at the chart: the orange design line should now sit below the dashed terrain line.
3. Tap Implement Slope, the green button at the bottom right.

The outlet is at the wrong end

Fix: See wrong outlet below.

Blade height was wrong when you surveyed

Check: The whole terrain line is shifted. See Grade looks off on your own survey.

Auto outlet picked the wrong end

Check: The app takes the low end of the survey as the outlet. Flat ground can fool it.

Fix:

1. In the design window, find the button at the top right that reads Outlet: Auto.
2. Tap it once. It turns orange and reads Outlet: Reversed, and the design line flips to drain the other way.
3. Check the chart, then tap Implement Slope.

1

In Terracing the button reads Reversed or Auto Flow. In the guided setup before the design, answer the water-flow question carefully.

Ditch depth limits are shading only

Check: The chart shades the stretch red as Over Max but doesn't move the line.

Fix, any of these:

• Change DEPTH OFFSET or MIN GRADE % with the + and − buttons.
• Use a fixed outlet depth: tap OUTLET DEPTH at the top (BestFit only).
• Draw the line yourself: tap the Guided or Freeform tab.

Tiling is different: it enforces a hard depth window.

You chose Start Fresh Job

Check: When you implement a revised design on a job with progress, the app asks Apply Revised Design? with two choices.

1 2

Fix: Next time, tap Keep My Progress to keep the worked surface and coverage. Old designs and jobs stay on the tablet, so an earlier job can still be reopened. A design saved under a name that already exists gets V2, V3 so nothing is overwritten.

Auto Nudge is off Most likely

Check: Look at the Auto Nudge switch in the top bar of the grade screen, next to the GPS badge.

Fix: Tap the switch so it turns green. With it on, Pass + and Pass − replace Nudge Up and Nudge Down in the sidebar; you get one pair or the other. The same switch is in the GRADING box of Settings.

Tiling and Excavation don't use Auto-Nudge

Fix: They're single pass by design. Use Nudge Up and Nudge Down.

Forming with a plain XYZ file

Fix: No proposed elevations means no cut/fill and no Auto-Nudge. Use an XYZP or AGD file. See Land Forming problems.

Passes = deepest cut ÷ Max Cut Per Pass

Check: Read Est. Passes in the green box on the design summary bar, under the cards. Max Cut Per Pass starts at 2 in.

1

Fix: raise the cut per pass before you implement (3 to 4 in suits loose soil):

1. Tap Implement Slope. The Auto-Nudge window opens.
2. Set a bigger max cut per pass there with its + button.
3. Tap Enable Auto-Nudge.

To change the starting value for every job, set Max Cut Depth (in) in the GRADING box of Settings.
