Just want to make sure I understand how to use the grid map
-
You can load the previously probed map with G29 S1 after homing, no need to re-do the map every time. So this is typically what you'd put in your start Gcode.
You normally only do a full G29 when the bed surface has changed, or some other maintenance happened on the printer.

I used the M122 and there is nothing for bed probes heights. When I click the view map I see the map of my bed. I must be missing a step somewhere to save the probe data. Any idea what it is?
-
The bed probe heights in the M122 report refer to bed probing with G32, so ignore them. Just look for the "Bed compensation in use:" value. If you can view the height map in the web interface, then the height map file is present on the SD card.
-
So if I have the map just issue a G29 S1 in my start up gcode and the map will load?
-
Yes.
-
I have the map loaded. Run the G29 S1. My Z steppers should move a bit shouldn't they? They are not, any ideas
-
If you are using bed compensation, your Z steppers should move a bit when you print.
After running G29 S1 you can run M122 and check the "Bed compensation in use" value.
-
Bed is not moving at all except for lowering to change level. M122 says Bed compensation in use: mesh
-
Would you notice it if the bed was moving only slightly?
-
Nope, Have a point there
