Extruder temperature drops after print start

[Saentis]

I'm new to the Duet 2 Wifi and I'm coming across a problem that I haven't come across in my searches.

I like to print at 215ºC and that's the temperature I've set in Cura. When I start a print, it gets up to that temperature and is able to get the first few layers of the brim when it stops extruding. I check the temperature and it's at ~160ºC. It looks like the active and standby temps change to 1ºC?

These are my temp settings in Cura:

Here's a video of it happening: https://app.box.com/s/0cst60mf3wstonf1fhc12uu0khpcqmfh

Can you post the gcode file this happens with?

[Saentis]

Yes, here's the gcode I tried printing in the video.

Try to print with disabled fan.

Actually forget about that. I didn't check the provided sample.

M190 S65
M104 S215
M109 S215
M82 ;absolute extrusion mode
; start_gcode
M117 Start Clean        ; Indicate nozzle clean in progress on LCD

all good up to here

M104 S[extruder0_temperature] 
M109 S[extruder0_temperature] 
M109 R[extruder0_temperature]

This is probably your problem. Check the start gcode that you have in Cura and delete or comment out these lines

That seems to have fixed it. Thanks!
