I'm trying to find out where the parameter "bed_temperature_initial_layer_single" is defined. After digging around in the dark, I stumbled upon a similar parameter "hot_plate_temp_initial_layer" in the filament definition screen, but cannot find "bed_temperature_initial_layer_single".
Also, in general, how do you find where parameters are defined (without just stumbling around)? There are magnifying glass search things, but none of them worked.
Helped me again. Thanks Accomplished_Fig6924
Your welcome. Glad I can help.
You helped me out a bunch a few days ago. I've been more successful printing since. Now I was working on my start macros in Klipper and the variable passing in Orcaslicer. Was having issues and then I saw this post and it all clicked. Now I have a working start_print macro with Orcaslicer passing in the nozzle and bed temps.
The new version has the enhanced gcode editor with the parameter browser. Try and use it to find the parameter
where can i find the parameter browser?
I'm trying to get klipper to work but i can't send the initial layer temp parameter for the hotend i get the error could not parse, while the bed parameter gets passed on...
Top left of the gcode editor is a little button.
ok, i see that in the browser the parameter nozzle_temperature_initial_layer has brackets at the end, while in the many guides i'm looking into there are not... should i put something in those brackets?
bed_temperature_initial_layer_single does not have them in the browser and it's in fact working...
Thanks!
Ok no looking at the generated gcode the temperature is specified well it'a a macro issue thanks anyway
Thanks i found it! stil hasn't soved my problem but it's something
Did you get your problem solved?
Yes... my problem was that i was able to pass the parameter to the PRINT_START from orca to klipper, but the PRINT_START macro ended calling the KEMP macro for creating the mesh and doing the purge line, my mistake was that the KEMP macro needs the parameter too.
i hope this is clear, if not i can pass to you my start.cfg so it's easyer to understand once i'm home (but don't just use it; i could be not suitable for your printer)
Thank you. Yes that was clear. I was curious because I had just got mine working.
Thought I would share it in the hopes of helping someone else.
Orca passes the heat temperature variables to print_start/start_print like this...
START_PRINT BED=[textured_plate_temp_initial_layer] EXTRUDER=[nozzle_temperature_initial_layer]
PURGE_LINE # call purge_line macro
Klipper's START_PRINT macro grabs the heat variables from the OrcaSlicer like so...
M118 --- Starting START_PRINT macro ---
{% set BED_TEMP = params.BED|default(60)|float %}
{% set EXTRUDER_TEMP = params.EXTRUDER|default(195)|float %}
M118 --- Setting bed temp to {BED_TEMP} ---
ETC. .........
I added some M118 commands so I could see what was going on in my Fluidd/Mainsail console.
The OrcaSlicer variables "BED" and "EXTRUDER" are entered under the print settings in OrcaSlicer. The values of these variables are included in the gcode OrcaSlicer generates. Then the START_PRINT macro assigns the values of "BED" and "EXTRUDER" to "BED_TEMP" and "EXTRUDER_TEMP" in the Klipper START_PRINT macro.
My START_PRINT looks like this...
[gcode_macro START_PRINT]
gcode:
M118 --- Starting START_PRINT macro ---
{% set BED_TEMP = params.BED|default(60)|float %}
{% set EXTRUDER_TEMP = params.EXTRUDER|default(195)|float %}
# Heat bed for probing
M118 --- Setting bed temp to {BED_TEMP} ---
M190 S{BED_TEMP}
# wait 5 minutes before bed mesh
G4 S300
# Use absolute coordinates
G90
# Home the printer
G28
# If you are using QGL:
#QUAD_GANTRY_LEVEL
#G28 Z
# If you are using Z-Tilt:
#Z_TILT_ADJUST
# If you are generating a new bed mesh:
M118 --- Generating new adaptive bed mesh ---
BED_MESH_CALIBRATE ADAPTIVE=1
## NOTE: The adaptive meshing feature requires exclude_object ##
## and may require 'Label Objects' to be enabled in the slicer ##
## To mesh without it just use BED_MESH_CALIBRATE ##
# If you are loading an existing mesh:
#BED_MESH_PROFILE LOAD=default
# Move the nozzle near the bed
G1 Z5 F3000
# Set and wait for nozzle to reach printing temperature
M118 --- Setting Nozzle temp to {EXTRUDER_TEMP} ---
M109 S{EXTRUDER_TEMP}
# added below dholden-24MAY2024
# wait 1 minute
#G4 S60
# Start printing!
# send message to Fluidd console
M118 --- Finished START_PRINT macro ---
Wow very detailed... Thanks for sharing!
Think your going to want to search bambu and prusa place holders as they all inter mingle with orca. I have yet to find a good list from orca specifically, just find it leads me to a bambu page.
Like for instance, I copied over my klipper slicer start from prusa to orca and it just worked, no going in and finding placeholders which was nice.
You will probably have to search for your specific settings, sorry. Just hover over the boxes and the placeholder should pop up.
