Loading heightmap error invalid grid

Patrick95

Hello everyone,
I have created an heightmap using my own script. When I try to load it via
G29 S1 P “heightmap.csv”
I get the error
Error: G29: Failed to load height map from file 0:/sys/heightmap.csv: invalid grid.
Attached is the heightmap.csv. I am using RepRapFirmware 3.5.2 and a Duet 3 6HC Board. I have also tried the whole thing with a simple heightmap with only zeros and 9 points, with v1 as version, actually pretty much everything. The number of rows and columns are also correct.
What is the problem?
Many thanks in advance

@Patrick95 You need the number of points on each axis, ie the last two parameters on line 3. Should be 11,11 rather than 0,0.

@Patrick95 Also, it's a rather weird looking map! Most of the outer points are negative, then jump to inner points that are positive, at a huge slant. Intentional?
