# Generating height map with Rep Rap

I recently did a G29 (run mesh calibration) and my printer did a 25 point probe and reported back the stats to the console. After this I went to the height map section and it says "height map not available" and no stats can be used here.

So I tried to load the height map using G29 S1 and am getting:

G29 S1 Error: G29: Failed to load height map from file heightmap.csv: Could not find file '/opt/dsf/sd/sys/heightmap.csv'

Does anyone know what I am doing wrong? Below is info about my control board and firmware.
