M581 in RRF3

chas2706

I have set up an external trigger to execute an e-stop on button press.
This is giving me two problems:

When enabled in config.g I get random e-stop occurrences. ( I have a normally open switch connected to gnd and in on io2.in).
In the documentation for M581 it says:

"When M581 is executed, if the T parameter is present but the other parameters are omitted, the trigger inputs and edge polarities for that trigger number are reported. "

Here is my config for M581:

M581 P"^!io2.in" T0 C0 ; configure active-low endstop to perform an e-stop and let it trigger at any time without restrictions

When I enter M581 T0 in the console I get this :

If I disable the M581 command in config.g I can print without problems,
BTW my endstops are configured and wired in the same way without issues.

@chas2706 I'm a long way from my printer with only my 'phone to hand so can't say for sure how mine are configured but try taking out the ^
