Warning: the height map has a substantial Z offset
-
maybe something to do with not having to probe the bed every time before i print

G1 S1 Z310 F3500 ; move Z towards the switch until it triggers
G1 Z-4 F900 ; move Z back 10mm
G1 S1 Z6 F600 ; move Z slowly towards the switch until it triggers
G1 Z-4 F900 ; move Z back 10mm
G1 S1 Z6 F400 ; move Z slowly towards the switch until it triggersIt's saying you may have an offset because it's using an endstop to home the Z axis before loading the heightmap. If the endstop position is perfectly set then you don't have an issue, but it will still warn you.

You sure?
I thought the offset warning was based on the contents of the height map file alone.
I tried to verify that but I couldn't figure an easy way to add a significant offset to each value in the file and then load it.

@Phaedrux so there is nothing i can do to get rid of the warning,, if not is it still using my heightmap as intended
-
You can get rid of the warning and any potential offset by using the z probe to home the z axis. (Provided your z probe z offset in g31 is correct).
If your first layers are good, then yes your height map is being applied and all is good.

@Phaedrux i only use the z probe only when i change something with my printer like a new bed or i switch out the nozzle to make sure everything is still good
-
@downshift64 could i go back to the board software that didnt have this warning
-
Is the warning that obtrusive?
-
@Phaedrux no just everything worked great before i upgraded the board just wanted to go back to that, that way i know everything works as it should
-
right now i dont know if its following the height map or the z min i set it to

Do two test prints. Once with G29 S1 active, and again with G29 S1 commented out. You should be able to tell if it's working as intended.
I don't think going back a firmware version to avoid a warning message is such a great idea. You also give up any bug fixes and improvements. But to each their own.
All the warning is saying is that the Z0 point wasn't established by a probe before the heightmap is loaded. As long as the Z0 point of the endstop is the same now as it way when the heightmap was created, you should have no issues. The reason the probe is preferred is that it's getting a current reading from the actual bed surface each time. No if your endstop is accurate and the build quality good (as it would appear yours is) then the endstop method is fine.
