Mesh Compensation in Gcode Start?

gumby

I have been using my homebrew delta machine, and I am still fuzzy on the mesh comp commands.

Here is what I have been using on my start gcode in my slicer:

G28 ; home all axes
G30 ; Probe Z height
G29 ; Probe Bed comp
G1 Z5 F5000 ; lift nozzle
M80 ; start pump

So here is my question. I saw running M561 cancels mesh comp. So, do I need a command other than my G29 to enable it? I was running a large circular shape, and my nozzle was getting way too close on one side, so that made me think maybe the G29 command only created the mesh file, but did not enable it. Does anyone here have insight on this topic?

Thanks in advance.

G29 by itself will run the mesh probing and enable it.

Thank You!

I wasn't sure... Then I can check that off the list and figure out what else it must be.
