Help Orca slicer : doesn't set extruder temperature

claustro

Hi guys,
I would like to try Orca slicer but I am having a problem with it.
If I start the gcode the bed is heated but the print starts with the extruder at ambient temperature.

this is the code generated

 EXECUTABLE_BLOCK_START
M486 S0 A"Cubo_id_0_copy_0"
M486 S-1
M73 P0 R10
M201 X9000 Y9000 Z100 E5000
M203 X30000 Y30000 Z720 E3600
M204 P9000 T9000 ; sets acceleration (P, T), mm/sec^2
M566 X420.00 Y420.00 Z24.00 E300.00 ; sets the jerk limits, mm/min
M190 S60 ; set bed temperature and wait for it to be reached
G10 S205 ; set nozzle temperature
;TYPE:Custom
G28 ; home all axes

G1 X170.854 Y150.136 F21000
G1 Z.2
G1 E1 F1800
;TYPE:Inner wall
;WIDTH:0.449999

Start Gocode

G28 ; home all axes

End Gcode

M104 S0 ; Extruder heater off
M140 S0 ; Bed heater off
M106 S255 ; Fan at 100 to cool nozzle and bed
G91 ; Relative positioning
G1 E-2 ; Retract filament 2mm
G1 Z20 F400 ; Raise nozzle 5mm from printed part
G90 ; Absolute positioning

Any idea if this is a problem with my setup or a slicer bug?

Thank you

I usually preheat the nozzle and bed before I print. I'm guessing that you don't preheat your nozzle and let the gcode do it for you. The printer will wait for the bed to heat up to 60 with M190 S60. But the G10 S205 after that won't be waited for. You can edit the gcode and add M116 after G10 S205 and it should wait for 205C to be reached before it continues. I'm sure there's a better way around it.

@claustro I know I'm very late here but I experianced some problems with Orca too. It may help somebody (probably me) in the future.

I use this in the start gcode in the slicer:

set global.tool_temp_initial={first_layer_temperature[initial_extruder]}
set global.bed_temp_initial=[first_layer_bed_temperature]
M98 P"/macros/print_scripts/start2.g"

My start2.g looks like that than:

; ##################### Custom Start G-Code

;M118 S"---------------------------------------- start2.g"

M118 S"Wait for the bed to reach temp"
M190 S{global.bed_temp_initial}


M290 S0 R0		; Set the babysteps back to zero
M118 S"Home all"
G28	            ; Home All
G1 X0 Y70 F5000 ; Move out of the way

; Wait till the corner sensor has reached 80% of  the bed
M118 S"Wait till bed corner has 80% temp"
M98 P"/macros/print_scripts/bed_wait_till_80percent.g"

; Clean the nozzle
;M118 S"Clean the nozzle"
;M98 P"/macros/print_scripts/nozzle_clean.g"

; Autoz plugin
;M118 S"AutoZ" 
;M98 P"/macros/autoz/autoz.g"

;M118 S"Stepper current high"
M98 P"/macros/print_scripts/xy_current_high.g"

;M118 S"Load hight map"
G29 S1	; Load height map and activate bed compensation (done by autoz.g)
; Unload
;G29 S2


; set hotend temperature and wait for it to be reached
;M118 S"Set first layer temp"
M109 S{global.tool_temp_initial}

;G1 E18 F500 ; extrude into the meltzone (revo)


; #### Nozzle CLean
G90         	      	; absolute positioning
G1 X220 Y259 Z15 F7000	; Move next to the brush
;M118 S":: Clean"
G1 Z5.00				; Drop to the cleaning hight
G91 	   		        ; relative positioning
; Start cleaning moves
;G1 X30 F5400
G1 X-45

G1 X-45
G1 X22
G1 Z7			; Raise nozzle and finish cleaning
G90            	; absolute positioning
M400



;M118 S"Purge Line"
M98 P"/macros/print_scripts/purge_line.g"

The benefit is that my config in the slicer is as agnostic as possible and I can switch the slicers far faster without syncing the "start g-codes" in the slicers.

Cheers, Chriss
