Got my system to home all with no issue. When running bed leveling I'm getting this error. I'm sure something in config is off.
Warning: the height map has a substantial Z offset. Suggest use Z-probe to establish Z=0 datum, then re-probe the mesh.

Please share your homing files and bed.g as well.
The offset warning means you may not be homing with the probe or loading a heightmap before homing.
The skipping point message just means that the probe can't physically reach points on the bed that you've asked it to probe. You can either ignore it, or adjust the M557 so that you're only asking it to probe points it can reach.

90 points probed, min error -0.608, max error 0.005, mean -0.318, deviation 0.144At what point do you get that error?
Can you post your slicer start gcode?
Can you take a screenshot of your heightmap being displayed?

@Phaedrux
It's at the end of the run. I believe at the around the last probe point it flashes that error. Last time didn't generate a map.On the other note, you mention redefining my mesh. Looking at the errors the probe is having issues at 200x. Should I adjust the M557 to

Your mesh range should be your axis minima and maxima values added with the G31 X and Y values.
M208 X-5.5 Y-10
M208 X235 Y235
G31 P25 X-48 Y-10
M557 X20:215 Y20:215For X- the probe is on the left side, so it can reach all the way to the X minima. In other words, the probe can reach all the way to the left side of the bed. How far from the edge is up to you. Let's try 10mm.
M557 X10
For X+ the probe can only ever reach 48mm away from the right side. So X235 + (-48) = 187. Let's say 180.
M557 X10:180
For Y, same thing, it's on the front side of the nozzle and can reach all the way to the Y minima. So Y10
M557 Y10
For The Y max, it can only ever reach 10mm away from the edge. So Y235 + (-10) = 225.
M557 Y10:225
Putting it all together.
M557 X10:180 Y10:225 P5
I used P5 here instead of a S value. P has the firmware choose 5 equally spaced points between the min and max values giving a 5x5 grid.
S defines an exact spacing, which means you have to find a spacing that maximizes the available size yourself. Easier to just tell it how many points to use.

Thank you, it's up and running. My current mesh
With a glass bed
Only other issue I'm getting is a,
Directory 0:/macros/ not found
Not sure why,
and I no macros in that folder. I wonder is somewhere in my configuration it's calling for a macro? -
Do you have a macros folder in the root of the SD card?
-
No, there was no macros folder so I added one.
