Migrating to Orca Slicer: Experiencing issues with the Start_Print G-code

[shiftynick]

Hey Everybody,

 

I am attempting configure my print start g-code in orca slicer, I'm migrating from SuperSlicer.  

The issue that I'm facing is that my extruder is not heating to the filament print temp set in Orca and is staying at the bed meshing temperature of 225.  Here is my print_start g-code:

'M104 S0 ; Stops PS/SS from sending temp waits separately
M140 S0
PRINT_START EXTRUDER=[nozzle_temperature_initial_layer] BED=[bed_temperature_initial_layer_single]'

 

Here's a link to my printer files: https://github.com/shiftynick184/My-Voron-2.4r2

I'm sure that I'm missing something silly but was hoping that you might have an idea or be able to point me in the right direction? 

Sincere THANK YOU in advance.

In your Print_Start macro you assign BED_TEMP and HOTEND_TEMP from the slicer to be called bed_temp and hotend_temp within the macro.

{% set bed_temp = params.BED_TEMP|default(100)|int %}
{% set hotend_temp = params.HOTEND_TEMP|default(225)|int %}

But you are having Orca Slicer export them as BED and EXTRUDER so the start macro doesn't actually get any value to assign to the variables it is using. I think the easiest fix would be to change your Orca Slicer g-code line to:

PRINT_START HOTEND_TEMP=[nozzle_temperature_initial_layer] BED_TEMP=[bed_temperature_initial_layer_single]

I don't know what the available Orca Slicer variables are so I can't verify that part of your custom g-code but if you check the end of a .gcode file that you have, there should be a long list of settings like this:

. . .
; first_layer_acceleration = 1000
; first_layer_bed_temperature = 100
; first_layer_extrusion_width = 0.42
; first_layer_height = 0.25
; first_layer_speed = 20
; first_layer_temperature = 245
. . .

Ty uncommenting the M104 and M140 commands there.
