Error loading and generating heighmap.csv

[Marcossf]

Hi everyone,

We have this error trying to active the mesh bed leveling:

Error: G29: Failed to load height map from file heightmap.csv: Unknown heightmap field: axis0

The file is present and we tried to delete and get a new probe map but the problem remains.

heightmap contains the matrix points obtained with the G32 (bed.g macro) but it seem there is a format? problem reading the data.

If we issue a new G29 S0 to get a new map file, the printer hangs at the finish, after the last point probed, the general status is IDLE but unresponsive and need to reset it to get it back alive.

Once reseted, the new heightmap.csv is there but it fails when enabling it again. This is the file created:

Tryed to get a G29 S3 p"file.csv" but the file.csv isn't made. Just hangs.

SBC mode, Duet 3 MB6HC + 1LC + 1XD version 3.4.0rc2

What to try for troubleshoot it? New bug?

[Phaedrux]

Can you share the results of M122 and M122 B# where # is the canbus address of the expansion boards?

Also please share your config.g

[Marcossf]

@phaedrux Our config.g its very complex and related to other files with a lot of variables and I think it doesn't give additional information.

All the axis are driven by 1XD boards, connected to OM closed loop external drivers and servos except the printheads which are driven by 1LC boards. In the +3.4 beta7 this was working fine. Prior to that, it was affected by the CANbus delay when probing, but resolved by David from this beta version. With the latest RC all works except this issue, at least the things tested so far.

I think, now the G29 command has a bug in the 3.4Rc2, that may be related to the modifications @dc42 did to solve this issue: https://forum.duet3d.com/topic/27248/3-4-rc1-1xd-probe-problem-after-update/3?_=1646900775328

M122 from the 6HC board, six 1XD and three 1LC doesn't shows any hint of failure. All movements works as expected except this error making or reading the mesh bed level file.

[Phaedrux]

Can you test with this build?

[Marcossf]

@phaedrux I'll try asap and back with the results.

[Marcossf]

@Phaedrux @dc42 With the version 3.4RC2+2 it doesn't work either. We drop the version files thru DWC and updated sucessfully all boards, while using SBC not standalone mode.

DSF and DWC are still in version: 3.4-b3. Are the parts that we still didn't updated.

Sending a simple code like this:
G28
G29 S2
G29 S0
Does the home OK, erase all mesh corrections OK, probe the area OK.

BUT, after the last probe point and retract the probe, the printer goes idle but it hangs up. The send button in DWC keeps doing circles and it's unresponsive until we reset it.

After reset, boot fine, and there is the heightmap file saved, but notifying at start console there's a error loading heightmap.csv described up there.

All remaining funcionality works well.

We need to get out this printer to customer asap (max. March18th) so we are concerned. If mesh bed leveling doesn't works properly the printer can't be delivered.

@marcossf said in Error loading and generating heighmap.csv:

DSF and DWC are still in version: 3.4-b3. Are the parts that we still didn't updated.

Those should be running 3.4 RC2 at least. I think this may be part of your problem. Are you able to update them using sudo apt update and sudo apt upgrade?

[Marcossf]

@phaedrux Right now i'm doing that. Soon back with the results.

Thx!

[Marcossf]

YES! That was the problem. I'm sorry for such stupidity

The heighmap file was done right and readed properly at boot. Waiting for a final stable version, hope soon!

Thanks! Have a good weekend.
