You need an S parameter (e.g. S4) on the last G30 to tell it that you want to do 4-point bed compensation. Otherwise it looks OK to me.

Isnt G32 supposed to triger auto bed leveling?
It just opens the automatic calibration results and does nothing.

Check the GCode Console page of DWC for error messages.

just did

G32
Bed equation fits points [60.0, 0.0, 0.000] [60.0, 190.0, 0.000] [160.0, 190.0, 0.000] [160.0, 0.0, 0.000]

It does not say its an error.

Yours, 1.20

My bed.g
M561 ; clear any existing bed transform

I did remove the M557 from the config.g, and also did a re-check on "whats new" for the firmware .. maybe I missed something?

It sounds like it isn't actually running bed.g. Is it in the right place and with exactly the right name? It's easy to put a comma before the 'g' character instead of a period. If you put a M117 command at the start of it to display a message, does the message get displayed?

It was in the right place (sys folder), I created it via web interface/system editor.

Dont know how, but now it works. I put M117 TEST MSG at the start, sent G32 code, the message was displayed and the auto leveling was done.

I noticed that te latest firmware generates the last G30 with only an S and not S4 at the end...

Why is that?

That's OK, S or S0 will default to the number of probe points.

I was asking myself a very similar question, so i tought why not just ask here.
Is there any reason not to use M500 at the end of my bed.g? Nobody is recommending this, but don't i need to save my probed points into my config-override.g?

Hope thtats the right place to ask.

The height map is automatically saved in a different file, heightmap.csv. You can use the G29 S1 command to load it in future instead of probing again.
