Probably DuetControlServer issue.

No problems creating or saving files from DWC2, even heightmap.csv. It just seems to be G29 that can't do it.
Running latest DSF.

yep this is a bug - not sure when it will be squished but its a known issue.

I'll try and track it down.

Yeah I guess that you can't tell the firmware to NOT do any file operations on G29 so when it fails to save to the onboard SD card and can't (because it doesn't exist), it errors out and doesn't even save the heightmap to RAM. That means you can't even do an M374 (which is handled by the DSF) or a G29 S3 (because it's not in RAM and because it's NOT handled by the DSF but should be).

I'll let you guys deal with it.

@dc42 Would you be OK with an RRF pull request that skips file io for gcodes when UsingLinuxInterface() is true?

@dc42 Pull request https://github.com/dc42/RepRapFirmware/pull/321
Skips file I/O for heightmap ops when UsingLinuxInterface() is true.

@chrishamm : Pull request https://github.com/chrishamm/DuetSoftwareFramework/pull/64
Fixes up the G29 S3 and M375 processing for Height maps.

With both pull requests, heightmap ops should be fully operational.

@gtj0 would you please elaborate a little on how to "deploy" these changes? or x1,000,000 better.. do you have a bin for Duet 3 version v0.6 (MB6HC) that has the heighmap fix in it?

@triumphantduke All of the changes required to make this work have been merged into the codebases and I believe that @dc42 and @chrishamm are close to doing the next release. I hesitate to post binaries because of this. If you want to build it yourself, you'd need to build the v3-dev branch of RepRapFirmware and the master branch of DuetSoftwareFramework.
