Mesh Bed Compensation Effectiveness
-
Hi,
To check I download that file, opened it and copy the contents into a file name test.csv on one of my printers and viewed it.
It was a complete "circle".
Thanks.

@fcwilt I wonder if it's being limited by my bed maxima. What do you have?

It's a mini-delta. I use 160mm as my diameter.

your not above the fade height when you take those measurements?

Hi,
I don't know what the "fade height" is - never heard that term.

Taper height
https://duet3d.dozuki.com/Wiki/GCode#Section_M376_Set_bed_compensation_taperThanks. I had not seen that before.

Interesting so far but back to one of my original questions.
Is there anyway to determine what a height map might look like when mesh compensation is working?
Or is there any documentation that describes in greater detail the workings of mesh compensation?
So far I have not be able to determine if it is doing anything on this printer. Dial indicator measurements have been the same with and without mesh compensation. Curious.

Given that the output of a mesh is just a csv... hand edit it to have some reasonable slope, but large, values, save it, reboot.
Activate mesh and do your dial again.
Maybe??

@fcwilt Are you sure it's being applied?
If you run M122 there should be a line saying
Bed compensation in use: mesh
Do you explicitly load the heightmap anywhere with G29 S1?
-
And to be clear, there are several things that DE-activate mesh... like G32 (which is in my print start script, for a smart effector)... so be sure a G29 S1 is in your "print start" (and that you've done one yourself when you dial to check).

That's a very good idea. I will try that.
Thanks.

Well at the start of the print the DWC reports mesh compensation is in effect.
Before taking my measurements with the dial indicator I have verified the state using the DWC.
Thanks.
