Am I using the G30 command correctly?
-
I noticed with my printer (with 3 Z axes) that when I execute G32 (to get the bed straight) and then do a mesh, the measuring points are always below the grid and a warning appears in the console.
Yesterday I discovered that if after aligning the 3 axes I make a G30 in the middle of the bed and then run the mesh, the measuring points are on the grid (with minor deviations, of course).My question would now be do I have to do a G32 (align Z axes) and a G29 S1 also a G30 before each print start or would e.g. another G28 Z in the middle be enough?
thanks in advance

Hi,
You need to do a single G30 in the center of the bed
- before creating a height map with G29 or G29 S0
- before loading a height map with G29 S1
- after leveling the bed with G32

Thank you, that's a clear statement that I know exactly how to use the G30
