; Input/Output
M950 J1 C"e1stop"
M581 P0 S0 T2 R0

Hi,

Well in the M950 you have J1 which specifies the pin number.

In M581 you have P0 which specifies a different pin number - I think.

yeah, i think you either need to use J0 or P1 to refer to the same pin in both M950 and M581 respectively.

i.e. if you have previously created J0 then stick with J1 and switch to P1 to mathc.

OT: https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_M581 seems to be out of date with respect to 3.1.1
