MB6HC can't delete heightmap.csv?
-
Hi all,
I can't seem to get my Z probe to act right, and in the process of trying I've discovered that using the "G29 S2" command+modifier does not seem to have any effect on the heightmap file.
Will it simply remain in the folder and display in DWC until I can delete it manually from the SD card? (i'm in standalone mode).
Or perhaps using "G29 S2" at the start of a file would simply make that print ignore any heightmap?
The height map itself is a whole separate issue, I'm thinking my IR probe might just never play nice with the coating on my glass bed. No matter what I do, it throws wacky numbers at me like full 1+mm differences that I can tell are just not there.
This led to me wishing to delete the heightmap and try my print with a manual bed leveling job, and this predicament
Here's my config.g if that helps

G29 S2 just disables the heightmap. It doesn't delete it. If you want to delete it you can delete it in the system folder in DWC.
One way to test the IR probe is to use a plain piece of paper on the bed and do the measurements. Some bed surfaces are just not going to work with IR probes.

Just found the plugin to turn off, that will do the job for now, I suppose.
Has anyone else had this experience with coated glass and an IR sensor?

Why do you think you need to turn off the plugin?
Having a heightmap file causes no issues if it is not loaded with G29 S1.

@terbospaghetti if you send M122, you'll get a load of info about the current state back. About half way down there will be a bit that will say
Mesh comp in use: noneorMesh comp in use: mesh
That will tell you if the printer is currently using the heightmap -

The IR sensor doesn't work well with glass beds having any sort of transparent coating. The problem is that the coating is never uniform, so the proportion of light reflected from the surface vs. light reflected from whatever is below the glass varies. Using matt black paint on the surface below the glass (or matt black paper under the glass) helps, but is not a complete solution.
