With ^ this map i still get the
Error: G29: Failed to load height map from file 0:/sys/heightmap.csv: failed to parse grid parameters -
@sbNielsen The main reason for it not loading is that you need to set radius to -1.
You don't need anything on the first line after "RepRapFirmware height map file v2", if these have been copied from somewhere else and are not accurate.
However, there's also a couple of mistakes. You need 18 X axis points, to go from 0 to 1700mm, other wise it goes from 0 to 1600. Also, the spacing is 100 for both axes, not 10. So first three lines should be:
RepRapFirmware height map file v2 axis0,axis1,min0,max0,min1,max1,radius,spacing0,spacing1,num0,num1 X,Y,0.00,1700.00,0.00,900.00,-1,100.00,100.00,18,10And you need to add an extra probe point value on each line of the probed points.

Strange, even though I get the error message, that it failed to load, I can still preview the map in the 'height map' tab.
And it corresponds correctly with the coordinates and the expected value.
Does that mean that it is loaded anyway or?

@sbNielsen No, the Height Maps plugin just shows the points, it doesn't load it. Use either
G29 S1or in DWC go to Control > Dashboard > Machine Movement and click on the 'Compensation and Calibration' drop down menu. I guess the plugin parses the file in a different, and less exacting, way from the firmware.Ian

@sbNielsen Did you update your firmware from the old release candidate (3.5.0-rc.1++) you are currently running?

No will do it now! -

Damn it, I change things to quick and then I fuck it up, sorry!
It works now! The main issues was the missing 18th column in the grid..
I feel stupid and happy haha, thank you for your help and patience!
