How do I view the results from the BLTouch probing on my Ender 3?

I have set up all the firmware and installed the BLTouch fine and it works as expected. But how am I able to see the results of the G29 9-step probes so I can view them in a mesh visualiser?

I don’t have an OctoPrint print server, as I know this comes with a Plug-in.

G-code M420 V will show the mesh heights of the currently loaded mesh.

You can use a console to send the command and retrieve the values.


I used Pronterface terminal emulator and connected the printer via USB! Simple really when you figure out how!
