Can you post the commands or macros you are using the create the heightmap? Does a simple g29 work to create heightmap.csv?

Yes, the heightmap.csv is saved, but not with the new name. Loading the map from Console with the full path also works OK.
Here's the macro, I think I found it here somewhere:; 0:/macros/primeline.g ; Home axes, wait for temps, create heightmap, and wipe a primeline ; Determine if we need to Home first or not if !move.axes[0].homed || !move.axes[1].homed || !move.axes[2].homed G28 ; Home all axes G90 ; Absolute Positioning.

G1 X110 Y110 F3000 G30 G29 S1 [P{"0:/sys/" ^ heat.heaters[0].active ^ "C_heightmap.csv"}] ; Load bed mesh for the slicer set bed temp. if result > 1 ; If the file doesn't exist, perform mesh and save. M291 P{"Creating a height map for the bed temp of " ^ heat.heaters[0].active ^ "C."} T10 M150 R255 B255 P128 S10 M116 ; Wait for temps G29 ; Perform mesh now.

It sounds like you upgraded from an older version but for some reason the permissions were not correctly set. Please open a terminal on your Pi or connect over SSH and run this
sudo chown -R dsf.dsf /opt/dsf. Then you should be able to save the heightmap again.I just tried to save a custom heightmap using
G29 P"foo.csv"and it worked as expected. -

Well, that was my first ideal also, so I setup everything from scratch, same result, before I posted here
All the files where uploaded from DWC, so I assume they have their rights set correct.
The problem is: saving the heightmap works itself from DWC's Console, but not from the Macro above.
I realize that the topic is misleading, but I can't change it. To sum it up:- Saving a heightmap with a different name (G29 P"foo.csv" from Console works fine, no issues
- Reading and saving a heightmap from within a macro leads to
[error] G29: Failed to save height map to file : Access to the path '/opt/dsf/sd/sys/' is denied.

@Tapetenhobel The square brackets are not needed so I'd remove them. But thanks for reporting this problem, I can confirm there is at least an issue with G29 (S0) when you attempt to save to a dynamic filename. That will be fixed in the next build but your macro shouldn't be affected anyway. I just tried G29 followed by G29 S3 and it worked as expected on my setup (without square brackets).

check the linux permission and ownership of that folder and the folders leading up to it

@chrishamm
OK, I will give it a try and report back. Thanks -
@chrishamm
OK, obviously removing the square brackets fixed it. Out of curiosity, why are the brackets a problem on SBC? -
G29 S0 (or G29 without parameters) does not support a filename parameter. See https://duet3d.dozuki.com/Wiki/Gcode#Section_G29_Mesh_bed_probe. This facility was supported when G29 was first introduced into RRF, but was removed subsequently because it required additional RAM. Use G29 S0 followed by G29 S3 to probe and save the height map to a named file.
