Bed mesh compensation not applied to all the tools
-
Can you upload all of the tool files. (drag and drop into the post window show do it)
-
Job starts with T2, I see bed compensation running
then T3 becomes active.
gcode file :T3 G91 G1 Z5 F600 G90As you can see I use G91 / G90 afteer T3 selection.
Could this explain that after this bed compensation doesn't work ?Thanks

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.
Board: Duet 2 Ethernet (2Ethernet)
Firmware: RepRapFirmware for Duet 2 WiFi/Ethernet 3.1.1 (2020-05-19b2)tpost1.g tpost0.g tfree3.g tfree2.g tfree1.g tfree0.g tpre3.g tpre2.g tpre1.g tpre0.g tpost3.g tpost2.g
I made severall tests again.
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.
-
Tfree1 tfree0 still has
;mesh levelling off
G29 S2And you've commented out all the G29 S1 to turn them on. Just remove all references to G29 in your tool files.

@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?
-
The change to T3 is done at about 3 mm.
I also thought at M376 H15
but the bed levlling is stopped before.
Thanks

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.

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

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 ; T3I recognize Z-35.26 is necessary.
@sylvain could you try commenting out M376 H15?

@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.

Commenting M376 solved the issue !
Thanks !

Very interesting! @Phaedrux if this is truly the cause, I wouldn't say this is expected behavior correct? Expected behavior would be G10 tool offsets having no impacts on mesh taper?
-
@sebkritikel I'll check with DC42 as I really have no idea.

For what its worth, I just tested it on my machine and can confirm G10 Z offsets will interact with with taper values set via M376, similar to what slyvain is seeing.
Duet2 Wifi+Duex5
3.2-beta2 (2020-10-05b2)Set M376 H15
With T0, with no offsets in G10, moved over built plate at Z=6mm. Could see ballscrews moving for compensationPut an artificial offset on T1 (IDEX) of G10 P1 Y.22 U.00 5 Z-20
Selected T1, bed moved down to account for Z-20 offset. Still read 6mm.
Moved T1 over build plate - no ballscrew/stepper movement for bed compensation.
Homed all axes, reset T1 offsets to G10 P1 Y.22 U.00 5 Z.3
Moved T1 over build plate (at Z=6mm), could see ballscrews/stepper moving for compensation.

Happy to have contribute to find a bug

@dc42 this comment should summarize the thread, while tested on an IDEX machine, should be easy to verify on a toolchanger.
