@Phaedrux Is there a line of code that creates a boundary as a safegard? Maybe I have to increase it? It seems something else is preventing it from going all the way.

@Phaedrux So I lowered my x to 205 and it is no longer giving me an error, but it isn't going all the way to the end of the bed? There is plenty of room, but it just keeps stopping short. Do I need to change a different value?

@oliof I have attached it.

Does anyone know why my BL Touch is not able to probe the end of the bed? I will attach photos of where it stops.

Thank you in advance!

@ScubaDoge

I am running into this error.
1/11/2023, 1:39:19 AM Warning: Skipping grid point X=210.0, Y=170.0 because Z >probe cannot reach it
Warning: Skipping grid point X=210.0, Y=210.0 because Z probe cannot reach it

If your probe offsets in your G31 are correct then there's no way the probe can reach the coordinates specified for your mesh.

G31 P500 X-40 Y-12 Z-1.6 ; set Z probe trigger value, offset and trigger height
M557 X10:230 Y10:230 S40 ; define mesh grid

The M557 points try to put the probe over the specified spot.
If the probe is 40mm to the left of the nozzle, then you can easily get it to X10, but to get the probe to X230 means the nozzle must be at X270, which is bigger than your stated X maxima.
Same applies in the Y direction.
Check your offsets using the method here

Then drive the head to the furthest points in X that you can safely reach with the probe and mark the points with some tape or a marker.
Then drive the nozzle to these points and take note of the positions. These will be your min max for M557.
Repeat the process for the Y directions.
You should end up with something like M557 X3:187 Y3:215 (assuming you leave a few mm from the edge of the bed) if your offsets are in fact X-140 and Y-12.

Owen thank you for that. It seems to be working a lot better now after those adjustments. I am trying to understand however why it isn't probing farther to the right. When I was running marlin, it would probe the exact center on its center home. When it probes with this software the nozzle is center not the probe. Do I have something set wrong?

@Phaedrux

Genius!

That definitely made a difference, and the height map looks a lot better.

If I have probe offsets for marlin, could I also use the same values with duet?

Also, I did notice it was skipping points on the bed.

I am running into this error.

I am trying to set up my printer with a genuine bl touch and it just seems to ignore my offsets and print in mid air. I get the following error when running g29.
