How to call the scan function G38.2 in GrblHAL

[GrblGru]

Sorry, I'm a little confused right now. Therefore maybe my stupid question.

I just wanted to test the function G38.2 with GrblHAL and I get the error message 20 "Unsupported or invalid g-code command found in block". My search for "g38.2" on this forum was unsuccessful.

Can someone tell me what is wrong with the command "G91 g38.2 z-10.000 f100" ?
GrblHAL provides this important function ... or ?

If your driver/board combo does not support a probe input the G38.x is not available. You may use the $pins command to check.
FYI in the Web Builder probe input is a selectable option.

Hmm, I'll have to check this out as the map file has the probe pin defined:

// Define probe switch input pin.
#define PROBE_PORT         	PIOB
#define PROBE_PIN        	13  // Due Digital Pin 21

Sorry, my mistake. Just flashed the due again. Probe' is now available. G38.2 does not give the error now either. Must still wire everything. Will try everything tonight.

Thanks a lot for your great help. :)

Sorry that I have to bother you again.
I now have a STM32 blue pill here and am testing the probing.
It works also so far well. When I look at PRB with $# after the measurement it looks good.

But I don't get a "[PRB: ..." message at runtime. I suppose that I can set it somewhere, but I can't find it.

It is enabled by the extended $10 setting flags (on by default when $10 = 511).
If you send $$=10 you get this output:

    0 - Position in machine coordinate (1)
    1 - Buffer state (2)
    2 - Line numbers (4)
    3 - Feed & speed (8)
    4 - Pin state (16)
    5 - Work coordinate offset (32)
    6 - Overrides (64)
    7 - Probe coordinates (128)
    8 - Buffer sync on WCO change (256)
    9 - Parser state (512)
    10 - Alarm substatus (1024)
    11 - Run substatus (2048)

Thanks again. You are the best. :)
