i have never used that function. i cant see it in the gcode using search

the gcode was made with S3d. ive added the start of the gcode file

current firmware is Firmware Name: RepRapFirmware for Duet 2 WiFi/Ethernet
Firmware Electronics: Duet WiFi 1.02 or later
Firmware Version: 2.02(RTOS) (2018-12-24b1)
WiFi Server Version: 1.22
Web Interface Version: 1.22.6

it did this on a previous 1, dont remember what firmware it was. tried firmware update to resolve it

ive been having this error come up at times.

the print will start correctly then part way will keep printing but no longer extruding.
i can not see a tool change, i have printed this gcode file successfully before on this printer.

@bustable

I have been trying to get my bed setup with duet for some time
every time i run it i get different different results. none resulting in a good print.
sometimes the probe barely touches the bed and triggers, sometimes it has to push in and i head a clunk.
running magball arms/smart effector with genuine e3d volcano

i have changed it from 20mm probing to 90mm and it didnt improve the results

this is my G31 command
G31 P100 X0 Y0 Z-0.1 0_1533473644711_config.g

this is what the calibration comes up with, this time, it varies between times.

i havent used my Delta for a while with duet and now im trying to use it again, the bed is all out of whack.
using smart effector

running the bed calibration and now it seems to have thrown the Z height out. it thinks it is 2-3mm lower than it actually is. if i go to 0 it grinds the belts.

how can i reset this, i cant seem to see it in the duet doco

I have recently installed the Duet wifi, smart effector and haydens arms but can not get it to probe correctly.

I can get it to either crash into the bed or to begin probing in mid air but not to slow down and begin probing correctly.
i have attached a video to show what is happening
