[Phaedrux]

Why is mesh levelling disabled in tfree and then reenabled in tpost?

[duetlover]

This is default configuration of E3D Tool Changer bundle.

[Phaedrux]

Can you try commenting out those lines? I'm not sure why it would be desirable to disable and re-enable mesh compensation during a tool change.

[duetlover]

I already tried commenting all G29 in tfree and tpost wihtout success

[Phaedrux]

Can you upload all of the tool files. (drag and drop into the post window show do it)

[duetlover]

Job starts with T2, I see bed compensation running

then T3 becomes active.
gcode file :

T3

G91
G1 Z5 F600
G90

As you can see I use G91 / G90 afteer T3 selection.
Could this explain that after this bed compensation doesn't work ?

Thanks

I don't think so.

I do think maybe there is a command to disable compensation in your tool changes, but I can't see the files to check.

Here it is.

I can see bed levelling on T2 (the fist tool used).
When switched to T3, no bed levelling.

Thanks !

Do you get any errors if you send M98 P"config.g"?

G29 S1 is commented out (turned off) in your tpost3.g (and your tpost2.g you just uploaded!!!) whereas it is not commented out (turned on) in your tpost1.g.

In addition to that, like @Phaedrux said, some of your tfree files have G29 S2 still active. Going from T0 to some other tool, you are disabling mesh compensation via tfree0.g, but then because it is G29 S1 is commented out in T2 and T3 it wont turn back on.

[Phaedrux]

Tfree1 tfree0 still has

;mesh levelling off
G29 S2

And you've commented out all the G29 S1 to turn them on. Just remove all references to G29 in your tool files.

[duetlover]

@Phaedrux said in Bed mesh compensation not applied to all the tools:

M98 P"config.g"?

=> no error

I will test with all G29 commented.

But as I told you I only use T2 and T3.

How could G29 in T0 or T1 could affect my print ?

All the more the print starts with T2 and bed levelling is active for this first tool.

Keep you updated !

How high (in millimeters) is the object you are printing when the printer changes from T2 to T3?

[duetlover]

The change to T3 is done at about 3 mm.

I also thought at M376 H15

but the bed levlling is stopped before.

Thanks

[Phaedrux]

You have T-1 in your config to deselect all tools, so perhaps that's when the tfree files are getting called.

Removing all references should tell us.

[duetlover]

T-1 and ALL G29 commented => same results...

When T2 is selected again after T3 bed levelling is running again.

I do not know, I'm sorry. It looks OK to me.

Just conjecture, but G10 and the taper command couldn't possibly be causing this right? I see no reason for that to be the case...

G10 P3 X-0.5	Y36.7	Z-35.26				; T3

I recognize Z-35.26 is necessary.

@sylvain could you try commenting out M376 H15?

Worth a shot.

Also, are you sure you've got G29 S1 enabled somewhere else now? Should be in the slicer start gcode or start.g at least.

[duetlover]

Commenting M376 solved the issue !

Thanks !
