M565 value

My printer says it's using -0.7 for M565 and that seems to work.

I've checked MatterControl setup and I don't see an M565 in the start g-code, I also don't see anything -0.7 in a M503 dump of the EEPROM.

In the source I see
#define Z_PROBE_OFFSET_FROM_EXTRUDER .9

It looks like it's stored in EEPROM and just not displayed with M503?

I would have expected it to be the Z value of M206

 

I'll check again when I get home but I'm pretty sure the source in the zip file I referenced has EEPROM enabled. It also defaults probe to -0.9, I'll power up the printer and without going into MC check the value in Pronterface which I know is not configured to set M565.

If it does work as I think it does it explains why they reworked it in v1.1.0 because it's working entirely different than other stuff that requires M500 to save into EEPROM after its value is set. What you described in the V1.1.0 thread is how that stuff is supposed to work. You can override but unless you issue a M500 it will not be saved and revert back to saved values on next reset.

 

Just verified on a clean bootup (no MatterContol) M565-0.7, it is saved to EEPROM but M503 does not display it.

EEPROM is enabled in the Robo configuration.h at least in The R1+ file in support.

//define this to enable EEPROM support
#define EEPROM_SETTINGS

That would make M565 the only setting I know of that automatically updates EEPROM instead of waiting for M500 to do it.

 

Yes I saw that discussion in the new version thread. If I didn't already have too many experiments on my plate I'd compile and give that one a shot but for once I think I'll just wait till it goes stable first.
