SOLVED:

I had my end stops configured as active-low rather than active high. DOH.

For others following this that may learn from it, here is my incorrect code:

; Endstops
M574 X1 S1 P"xstop"                                    ; configure active-high endstop for low end on X via pin xstop
M574 Y1 S1 P"ystop"                                    ; configure active-high endstop for low end on Y via pin ystop
M574 Z1 S1 P"zstop"                                    ; configure active-high endstop for low end on Z via pin zstop

HERE IS THE CORRECT CODE:

; Endstops
M574 X2 S1 P"xstop"                                    ; configure active-high endstop for low end on X via pin xstop
M574 Y2 S1 P"ystop"                                    ; configure active-high endstop for low end on Y via pin ystop
M574 Z2 S1 P"zstop"                                    ; configure active-high endstop for low end on Z via pin zstop

@Phaedrux Yes. If i boot up the machine from powered off and send M501 as the first thing I do, it loads the values from the override files and you can see the Z value change.

@dc42 Thanks David. That is how I understood it as well. So what am I missing?

Bump, any other ideas?

@droftarts
Nope, i don't think that is it. I pasted it in BBEdit, and it looks clean. I think the form code snippet tool added those {1}'s.

@droftarts said in RRF3.01-RC12 Not Loading Config-Override.g on startup?:

@KeeganB Try sending M98 P"config.g" and see if you get any errors. Not sure of the effect of those '{1}' lines at the end of the config.g.

Interesting. Those {1} values don’t show up in the dwc editor. They only appeared when I copied and pasted. I wonder if that’s the issue.

I’ll try pasting to a text editor, cleaning those up, and then saving a new config.

I'm happy to post my config, bed, override, and etc files.

I highly doubt my M500 parameters are an issue. As I said, after running M500 the override is updated properly.

I just finishing re-doing my config.g to move my SeeMeCNC Orion (delta) over to RRF3.

After finishing the config.g, I can set my z=0, run through a few G32's, get a good calibration, and then persist in via M500.

The config-override.g is created and every time I G32 and then M500, the values are properly updated.

All works fine after that, UNTIL... I reboot the machine.

It doesn't seem to be loading the values from the override file on startup. It sets the Z height to the value from my M665 in config.g. so when I home it, it adds the z distance it travels to get home to the starting Z value from config.g so I end up with a Z height value when homed that is too high (usually about 15mm as that is the distance I drop the carriages at the end of my home-delta.g file.)

I DO have an M501 at the end of my config.g. The only line after that is "T0"

Thanks!
