Detective needed

Using 057y firmware and 065 web control via Chrome – working well together for some considerable time.

Trying several times to print a new x-carriage in ABS, with zero success.
Always using SD drop to transfer the file, then do an SD print.
Usually manual head(240) and bed(120) heating whilst doing the Z axis setting.
Mostly the printer moves to the start position, with the bed light on and temperatures pretty steady, typically at 218 and 112 (this morning's run) – absolutely no action.
Tried an old ABS file on the SD card (thin wall test), and that ran until the whole head sagged with the heat.
I had previously made a spare x-carriage so I replaced that.

Suspected an SD card fault, so deleted all files, re-formatted, and copied back a selection of files ( including that thin wall test)
Tried again this morning with the same results – moved to the start position, then just sat there with the bed heater light on, and the temperatures not moving from 218 and 112
NOTE the bed temp set in the Gcode (below) was 110, and the heater light was on.
Thinwall test started to run OK – until the head sagged again.

Decided to run same the x-carriage file whilst writing these notes. No initial warming – just go straight to the file – and the bed heater NEVER came on – started moving and extruding when the head was hot. See the temp chart below.

Suggestions?

Initial part of the G code file which always goes wrong

G21 ; set units to millimeters
M107
M190 S110 ; wait for bed temperature to be reached
M104 S230 ; set temperature
G21 ; set units to millimeters
G90 ; use absolute coordinates
M83 ; use relative distances for extrusion
G1 Z5 F200 ; lift nozzle
G1 X2 Y50 F2000; Go to wait for warm position
G10 P0 S220 R0 ; Set extruder temperature
T0; Select extruder
M116; Wait for all temperatures
M109 S230 ; wait for temperature to be reached
G90 ; use absolute coordinates
M83 ; use relative distances for extrusion
G1 F2700.000 E-4.00000

Initial part of the old G code file for the thin wall test

G21 ; set units to millimeters
M107
M104 S235 ; set temperature
G21 ; set units to millimeters
G90 ; use absolute coordinates
M83 ; use relative distances for extrusion
M140 S105; Set bed temperature
G1 Z5 F200 ; lift nozzle
G1 X2 Y50 F2000; Go to wait for warm position
M116; Wait for all temperatures
G10 P0 S205 R0 ; Set extruder temperature
T0; Select extruder
M116; Wait for all temperatures
M109 S235 ; wait for temperature to be reached
G90 ; use absolute coordinates
M83 ; use relative distances for extrusion

M190 is not supported by the Duet firmware. Use M140 followed by M116 instead.

Interesting.
Sli3er put that in - not me.
I think I may have put in the G10 command in the middle of the custom G code.

Will try later - trying currently to sort out the sagged hot end

Sli3er still inserting the M190 - any idea where that has come from? I have not updated it at all, and I cannot find mention of M190 in any of the AppData stuff
It certainly never appeared previously.

Hot end tightened and levelled up - now printing some more replacement parts in PLA (after I manually corrected the new M190's)

I believe that Slic3r will only insert it's own temperature settings at the start if the custom start G code does not contain any relevant temperature setting commands and the temperature is not set to 0 in the settings.

Greg,

Seeing that slic3r seems to generate M190 codes, I've implemented this in firmware 0.59beta, which you can find at [dl.dropboxusercontent.com].
