removing a warning height map message

@stephen6309 said in removing a warning height map message:
@fcwilt I used them to make it easier to set them. I just changed to a chimera, and only had to edit that file with the new offsets and run it, since I also use them in the macros to set my G31. Don't like to edit config.g, too many times a typo foobared it.
Got it.
I deal with that sort of thing, where the values are not likely to change, by putting the needed commands in a separate g-code file in the sys folder.
For example I put all of the Z probe configuration commands in a file name probe_config.g. I include a M98 P"probe_config.g" command in any other file that is about to use the probe, so the most recent settings I edited into probe_config.g are applied. No need to re-boot the printer, just edit the file and the changes will be used.

hi sorry for lte response, but i'm on delta , and i use Homedelta.g, but this warning message come when i launch a print job, and only on my delta printer ... not on my CR10...and on this my mesh is 6 month old... so i'm not understanding why....

You may just need to add a single G30 at the center of the bed right before the heightmap is loaded to eliminate the warning.

@phaedrux
prusa slicer start gcodeG28 ; home all axes G1 Z5 F5000 ; lift nozzle G29 S1Well there you go. G28 will call home delta, which uses the tower endstops to set position. Then you load the heightmap which was created by the probe.
I suggest you add a single G30 after the G28 and before the G29 S1. That should get rid of the warning.

@phaedrux you're right ! just trying now, and your solution remove my warning mess...
Many thanks for help

Many thanks for helpThat single G30 sets what is called the Z=0 Datum. The practical result is, once set, moving to Z=0 should have the nozzle just touching the bed, or nearly so.
You needed to do that before creating heightmaps and before loading heightmaps.
That insures that the Z=0 position was consistent and accurate during creation and loading.

@sebxtreme You have G29 S1 in config.g, remove it.
-
In theory, if your delta homed height is set perfectly, it should give the same Z0 result as the probe (assuming it's trigger offset is also set accurately), but it's far easier to just let the probe dictate the bed position.

@phaedrux yes the G30 give the same height of my config each time . many thanks.
