Temps are set to 0C When using start print macro

[Awesome4all]

OrcaSlicer Version

1.9.0

OS version

Windows 10

Additional system information

CPU:Ryzen 5 5600x RAM:32GB DDR4 3200Mhz GPU:ROG STRIX 3060ti

Printer

Ender 3 v2 Neo running Klipper

How to reproduce

1. Open Orca Slicer
2. Click Create New Project
3. Select the the Creality ender 3 v2 system profile
4. save as new profile
5. edit start gcode to START_PRINT EXTRUDER_TEMP=[nozzle_temperature_initial_layer] BED_TEMP=[bed_temperature_initial_layer_single]
6. save profile
7. add any new model
8. press slice plate

Actual results

After slicing the plate under color schemes, change to temperature. it shows 0c.

Expected results

After slicing the plate under color schemes, change to temperature. it shows 240c.

That looks wrong, I have my Voron set like so:

PRINT_START HOTEND={first_layer_temperature[initial_extruder]} BED=[first_layer_bed_temperature]

Also, even so your variables might be correct, the single major problem from Ender folks coming from Cura is that their macros are incomplete. Meaning, PRINT_START does not have the nozzle and bed variable set so the macro does not know what to do with that information. This is more an user/printer/klippepr issue than slicer issue itself.

Nope the issue still occurs.

also i initially started on prusa slicer and then to orca slicer and then to klipper+orca

I have both print_start and Start_print `[gcode_macro print_start] gcode: {% set BED_TEMP = params.BED_TEMP|default(60)|float %} {% set EXTRUDER_TEMP = params.EXTRUDER_TEMP|default(220)|float %} POWER_ON_PRINTER G4 P10000 ; wait for printer to turn on G90 ; use absolute coordinates M83 ; extruder relative mode M140 S{BED_TEMP} ; set final bed temp M104 S{EXTRUDER_TEMP} ; set temporary nozzle temp to prevent oozing during homing G4 S10 ; allow partial nozzle warmup G28 ; home all axis BED_MESH_CLEAR BED_MESH_CALIBRATE G1 Z50 F240 G1 X2 Y10 F3000 M190 S{BED_TEMP} ; wait for bed temp to stabilize M109 S{EXTRUDER_TEMP} ; wait for nozzle temp to stabilize LINE_PURGE

[gcode_macro start_print] gcode: {% set BED_TEMP = params.BED_TEMP|default(60)|float %} {% set EXTRUDER_TEMP = params.EXTRUDER_TEMP|default(220)|float %} POWER_ON_PRINTER G4 P10000 ; wait for printer to turn on G90 ; use absolute coordinates M83 ; extruder relative mode M140 S{BED_TEMP} ; set final bed temp M104 S{EXTRUDER_TEMP} ; set temporary nozzle temp to prevent oozing during homing G4 S10 ; allow partial nozzle warmup G28 ; home all axis BED_MESH_CLEAR BED_MESH_CALIBRATE G1 Z50 F240 G1 X2 Y10 F3000 M190 S{BED_TEMP} ; wait for bed temp to stabilize M109 S{EXTRUDER_TEMP} ; wait for nozzle temp to stabilize LINE_PURGE`

either way the slicer still wont show that im printing at 240 c

im trying to print petg

[Awesome4all]

it looks like this: but needs to look like this:

Please export and share a gcode file

I figured it out when putting the start macro in orca you have to match it with the start macro in klipper so for this section in klipper {% set BED_TEMP = params.BED_TEMP|default(60)|float %} {% set EXTRUDER_TEMP = params.EXTRUDER_TEMP|default(220)|float %} i originally had PRINT_START EXTRUDER=[nozzle_temperature_initial_layer] BED=[bed_temperature_initial_layer_single] PRINT_MIN={first_layer_print_min[0]},{first_layer_print_min[1]} PRINT_MAX={first_layer_print_max[0]},{first_layer_print_max[1]} what needed to be changed was the EXTRUDER and BED section to EXTRUDER_TEMP and BED_TEMP to match the prams.EXTRUDER_TEMP and the prams.BED_TEMP section

thank you for you help

Yup, but again this isn't an OrcaSlicer problem. Your Klipper macro was previously set with custom variables names instead if the variables commonly used by Klipper printers. It was the first thing I mentioned, Ender folks with this same problem appears often on discord.
