All temeratures are 0 as soon as first layer starts / Slicer-Start Macro-Klipper interdependency

hey!

I use orcaslicer and a vanilla klipper printer and have not tuned in everything yet.
i.e. I have the problem that all temps are reduced to zero after initial warm up and print start.

I believe it has something to do with the start_print macro but wonder about it.

Can you please let me know a place where to go?
Im not sure if this is the right place here since I suspect rather a configuration issue in conjuction with the use of Orca than a Klipper problem.

Happy to hear your feedback about my macrosin case you find obvious flaws. Thank you!

Not quite vanilla.

The klippy.log is quite short (except the bedmesh coordinate: almost 1000 lines).
There is no heating up and/or cancelling to find.

Please start a print again, when the issue occurs, do a M112 and attach the new klippy.log to your next post. Also the Gcode file that you want to print and/or the start print script from OrcaSlicer.

yes sure, will do.
It is short because I set up the system fresh just before and this was the first print.

here is the gcode file:

adapterplate_2024_PETG_54m30s.gcode (973.2 KB)

This is the start Gcode in the slicer:

START_PRINT EXTRUDER_TEMP=[first_layer_temperature] BED_TEMP=[first_layer_bed_temperature]
CHAMBER=[chamber_temperature]

M104 S0 ; Stops OrcaSlicer from sending temp waits separately
M140 S0

Here I reproduced the error and this time executed M112 after “Temp extruder too low” notification popped up.

klippy (1).log (1.4 MB)

START_PRINT EXTRUDER_TEMP=[first_layer_temperature] BED_TEMP=[first_layer_bed_temperature]
CHAMBER=[chamber_temperature]

M104 S0 ; Stops OrcaSlicer from sending temp waits separately  # <--------
M140 S0                                                        # <--------

You turn them off yourself.

This occurs:

Unknown command:"CHAMBER=0"

This in the gcode file

START_PRINT EXTRUDER_TEMP=250 BED_TEMP=80
CHAMBER=0

should be one line

START_PRINT EXTRUDER_TEMP=250 BED_TEMP=80 CHAMBER=0

So in the slicer

START_PRINT EXTRUDER_TEMP=[first_layer_temperature] BED_TEMP=[first_layer_bed_temperature] CHAMBER=[chamber_temperature]

Nice :+1:
Commented this out and removed excess line breaks. Works!!

Regarding chamber unknown command. I still had chamber_heater in the configuration. So I had to rename this one and this error is gone as well.

I copied the slicer start G codes from somewhere. I think Orca is having this as a recommendation. Didn’t give it a lot of thought but obviously it was completely wrong.

That’s the problem with copy random scrips.
Check what they do before using them.

Well it’s the oem recommendation for this printer type in conjunction with Orcaslicer. I think that’s why I didn’t second guess the code. Really strange. Will double check since it really doesn’t make sense now when I look at it. The scary part is that I could have sworn that it worked quite good last week with the same slicer settings :man_shrugging:

Thanks again, really great feeling to have a good working machine.

PS: I have one last Linux issue and in depth questions regarding lsmod and kernel modules.
Where is a good place to go for these Linux-3D print-armbian questions?
