Saving levelling map with G29 S3 does not work

[grizewald]

If I try to save the current levelling map to a specific file name with:

G29 S3 P"mesh70.csv"

I get an error returned and no file is created. The error message is:

Error: G29: bad or missing parameter

I'm using firmware 2.03 on a Duet2 WiFi.

Am I missing something or is this a bug?

The reason I want to do this is that the way my bed warps changes with the bed temperature, so I wanted to create two levelling maps, one at 50°C and another at 70°C and load them as appropriate with filament specific G code.

You need to update your firmware to 2.04

From GCode manual.
S3 Save height map (supported in RepRapFirmware 2.04 and later)

HTH Paul.

That was right in front of me when I was reading the documentation as well.

Thanks.
