Mesh Grid - Result is not ok
-
i dont understand the example from the wiki
https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motorscan you give me some help
thank you
-
New Automatic Calibration Results
what i can do to make it better without to buy new hardware is it possible ?
thanks
-
-
It looks like you had a large probing error at one particular point (the red one). Is it repeatable? Is there anything special about that point?
-
Which firmware version are you using?
-
-
No nothing particular on this point
Every mesh grid The same point
I use the last Firmware 2.02
I have read that i can use The E1 for a second z motor Drive? Is it correct ? So i can use The Wiki link Fromm dc42 ?
-
This is my 3dPrinter
-
Nothing?
I dont be forward still same Problem.
-
so i have made some changed
2 indepedet motors for Z ( ZA and E1 )

But here you have only performed bed level with the leads crews. Not any mesh, i.e. G29. At least I don't see that in bed.g file.
There is something seriously wrong.... Why are the x and y coords of you sample points not in a grid? Isn't that that the plot straight from above?it must the perspective...
Why do you deploy for the ir sensor? -
Hi
Thanks for your answerAlso i have to add this code in bed.g
; mesh probe
G29 S0My english is not The best can you give a advise
-
i think i found the problem i have insert bed leveling with mesh
now i have only mesh

-
Does your bed surface have a bit of a reflectiveness to it? Can you try probing your bed with a piece of plain white printer paper on it? I'm thinking maybe the IR probe isn't getting a good reading from your bed surface.
-
I have The buildtak Vertex
I will Test it tommorow
If its reflectiveness what i can use to probing?
-
You can try adding an A and S parameter to your M558 command to try and increase probing consistency.
M558 A10 S0.003this will cause the probe to probe up to 10 times if the consistency of two consecutive probe results are within 0.003mm of each other.

Like this

@lui2004 Yes

Ok i i will test now

Try increasing your dive height perhaps? I'm not super familiar with the behaviour of the IR probes.
I can't tell from the number grid if that's an improvement or not. Does the image look more consistent?
-
Is there any direct lighting around your machine? is your machine around any natural (outside) lighting? I have read that florescent lighting and possibly LED lighting can cause issues.
