Describe your issue:
Klipper not retaining pressure advance settings and it’s not taking the temps from my slicer, it’s staying on the default temperature. I’ve been trying to get a calibration cube to print with Klipper now for 2 weeks and am about ready to chuck the entire printer in the river I’m so frustrated with it. klippy(1).log (714.6 KB)
Seriously if anyone has a step by step troubleshooting guide that they like please let me know, I’m just at my wits end. I’ve been able to get a bed mesh created but that’s about the only useful thing I’ve been able to get Klipper to do.
…
So I’m completely new to Klipper I’m using Cura, I just have START_PRINT to call the start print macro. I have the defaults in the START_PRINT Macro and that’s what gets loaded everytime. I suspect Cura isn’t passing something correctly and it’s probably user error. I cobbled together the macro I’m using from stuff online.
Here is the macro:
[gcode_macro START_PRINT]
gcode:
{% set BED_TEMPERATURE = params.BED_TEMP|default(75)|float %}
{% set EXTRUDER_TEMPERATURE = params.EXTRUDER_TEMP|default(210)|float %}
{% set OFFSET=params.OFFSET|default(0)|float %}
# Wait for bed to reach temperature
M190 S{BED_TEMPERATURE}
# Home the printer
G28
# Load Mesh Bed Level
G29
# Move close to the coordinates origin
BED_MESH_PROFILE LOAD=default
G1 Z2.0 F240
G1 X2.0 Y10 F3000
# Start bed heating
M117 Heating bed
M140 S{BED_TEMPERATURE}
# Use absolute coordinates
G90
# Reset the G-Code Z offset (adjust Z offset if needed)
SET_GCODE_OFFSET Z={OFFSET}
# Wait for bed to reach temperature
#M190 S{BED_TEMP}
# Start nozzle heating
M117 Heating nozzle
M104 S{EXTRUDER_TEMPERATURE}
# Set and wait for nozzle to reach temperature
M109 S{EXTRUDER_TEMPERATURE}
# Prime line
PRIME_EXTRUDER
M117 Printing
Is the entire start code in CURA. I used to have a bunch of other stuff in there for Marlin because I was using a different flavor of it than the stock creality. I should still have it somewhere if you need to see it.
Thank you, that part seems to have worked, if I can pick your brain about one more thing, settings like pressure advance don’t get saved. And while I can calibrate my z offset it doesn’t load it correctly even though it’s saved in the file. My call looks like this:SET_GCODE_OFFSET Z={z_offset} but when I try to run a print, it says it can’t parse it. If I comment out that line, it works, but doesn’t use the z offset even though it’s saved in the generated section as z_offset. I assume there’s a syntax error but I don’t know what it is.
This is because your START_PRINT macro is setting the z offset to 0. You need to pass the desired offset to START_PRINT using the OFFSET parameter just like you did with the temperature parameters.
START_PRINT is a custom macro that you chose to use, not part of Klipper. For a comprehensive list of parameters that it cares about all you have to do is read the macro.
I would like a full list of parameters klipper can access. I have what I need with the macro. But I would prefer to solve my own problems with the documentation rather than constantly ask for help. I have yet to find a list of parameters that klipper can reference in macros. As I suspect I’ll be creating more custom macros once I become more comfortable with Klipper. Appreciate your help though.
I think @flowerysong misunderstood what you were requesting because “parameters” in this context usually refers to the variables/arguments that can be passed to and used by a macro. And since those are defined in the macro and can be anything you want, there obviously is no list of them except in the macro itself.
