Actually, I think I have found the answer.

M581 seems to be the way. It is well documented in https://duet3d.dozuki.com/Wiki/Gcode

I understand that Duet has the capability to run Gcode triggered from a hardware input via an unused endstop port

I want to wire some hardware buttons to stop, pause and resume my CNC job

Can someone point me in the right direction to find information about this?

Peter

Can we please have the current co-ordinates shown on the "Move" page

There is plenty of room on the screen

Can someone tell me how to set a static IP for my Duet 3D. I have seen similar threads from other users with the same problem but nothing seems to work for me.

I have tried loads of different methods I have read online but whatever I do, the IP address stays at 192.168.1.28 which is set by DHCP

This is the relevant bit of my config.g

; Configuration file for Duet WiFi (firmware version 1.21)
; executed by the firmware on start-up
;
; generated by RepRapFirmware Configuration Tool v2 on Fri Mar 01 2019 11:38:38 GMT+0000 (GMT)

; General preferences
G90 ; Send absolute coordinates...
M83 ; ...but relative extruder moves

; Network
M550 P"My CNC" ; Set machine name
M552 S1 ; Enable network
M587 S"" P"****" I192.168.1.9 J192.168.1.1 K255.255.255.0 ; Configure access point and IP addresses. You can delete this line once connected
M586 P0 S1 ; Enable HTTP
M586 P1 S0 ; Disable FTP
M586 P2 S0 ; Disable Telnet

As far as I understand, this should set the IP to be 192.168.1.9 but it doesn't work

Can someone help please?

Peter
