When I try to load a height map using G29 S1 , I get the following error
Error: Failed to load height map from file heightmap.csv: number expected at line 3 column 201

Please post your heightmap.csv file.

I should also have stated that I'm using 1.18beta1

Any Idea what is happening with the height map file. I installed Beta 2 but it is the same thing

[dc42]

That's a long bed! My guess is that the large number of points along it (27) is causing the file line length limit to be exceeded. For now, try a larger grid spacing to reduce the number of points along the X axis.

Thanks that solved the problem went from 20mm grid to 40mm

Fixed in 1.18beta3. Max number of points along the X axis is 25 in 1.18beta2 and earlier.
