Error : "extruder" not hot enough

[unkempt cairn]

Is it normal that I have two extruder temperature showing ?

I'm having issue when printing : "extruder" not hot enough. My printer used to work fine until recently.

I did : PID_CALIBRATE HEATER=extruder TARGET=210
PID parameters: pid_Kp=29.179 pid_Ki=2.138 pid_Kd=99.576
The SAVE_CONFIG command will update the printer config file
with these parameters and restart the printer.

But I still get that same error when launching a print ; "extruder" not hot enough . Anyone knows what I can do ?

In SSH Biqu I do see two Extruder, one with extruderTMC and the second is written simply extruder.

My gcode is : PRINT_START EXTRUDER=[first_layer_temperature] BED=[first_layer_bed_temperature] CHAMBER=[chamber_temperature]

[shut mural]

notice the different symbols next to each entry? the lower "extruder" is some separate sensor, possibly a TMC driver sensor depending on the model of your toolhead PCB (eg EBB 2240)

the error is likely unrelated to these sensors. a klippy log would be helpful to investigate further.

Show more of the console output

What does it say BEFORE the extruder not hot enough?

[unkempt cairn]

Thanks guy's, I will report later today. When a launch a print, it starts to QGL and heats up bed & nozzle but then stops saying : "extruder" not hot enough. Maybe there is something I need to change in SSH

[crisp pawn]

I’m 75% sure that some step of your print_start is failing, and the rest is just the aftermath of that failure

[unkempt cairn]

Here is my print.cfg file

[unkempt cairn]

It works again ! 🙂

[unkempt cairn]

I have an error when saving PROBE_CALIBRATE, do you know why ?

[crisp pawn]

I mean, according to the message, your save_config block is corrupted

oddly, in the config you posted earlier, its also blank, so I'm not quite sure what its mad about specifically

[unkempt cairn]

I'm getting "extruder" not hot enough, again

Maybe I need to do something in SSH/Biqu ?

[crisp pawn]

No, you need to read what the console is saying

“Probe triggered prior to movement”

That’s a hard abort on your qgl , and therefore your entire print start

What you need to figure out, is WHY the probe is aborting like that

Could be that the probe is dragging on the bed because that corner of the gantry is too low (a higher horizontal_move_z can help with that) or it could be a bad wire acting up….

What probe are you using?

[unkempt cairn]

I'm using a high temp Prob. I'm launching a new print, to see what happends

[crisp pawn]

I don’t know what that means

What actual probe is it?

Like the probe

The device used for qgl and meshing

Nothing to do with temperatures

I guess I should elaborate on that: the actual temperature error is entirely spurious

That is only happening because of this other problem, during qgl. Qgl aborts. Then as a result of that the print_start aborts. Since print start aborts, the hotend never gets its target set

So fix the qgl issue, and the rest takes care of itself

[unkempt cairn]

I'm using the TAP system, doest this reply to your question ?

[crisp pawn]

The original reply didn’t say anything about tap. 😛

The new one does!

(And yes, the new answer answers my question)

[unkempt cairn]

TAP system 🙂

[crisp pawn]

So ya, first thing to check is whether tap is dragging on the bed during qgl

[unkempt cairn]

How could that possibly lead in showing : "extruder" not hot enough

[crisp pawn]

I answered that, in detail

Start at “I guess I should elaborate “

I explained exactly why a tap/qgl error is the real problem, and the extruder error is just chaotic aftermath

[unkempt cairn]

After turning the print OFF for several minutes, I am not having this "extruder" not hot enough error showing.. It is now printing again...

I just broke the piece that locks the filament... Is this piece mendatory, can it work well without ,

?

[shut mural]

it's needed to properly tension the extruder

you'll need to replace it

[unkempt cairn]

To tension the filament or extruder ?

Shiiit 🙁 I must replace it, it won't work good without ?

[crisp pawn]

Without that, the extruder gears wont grab

[shut mural]

do you have another ABS capable printer?

[unkempt cairn]

Ahh! I must disable the whole thing again. I'm having too much issue with the Voron, mega time consuming! 🙁

[unkempt cairn]

I know a guy in Paris who can help me re-print something

[shut mural]

ok. if you struggle to get parts we have a network of volunteers who can help out, let us know

[unkempt cairn]

In Paris, France ?

[shut mural]

even in paris, yes

[unkempt cairn]

Really ? Could you hock me up with them please

I use a CW2, is it bad ? Do I need to upgrade to motor pancake ?

[shut mural]

how old is the printer? there have been a few revisions of that part

[shut mural]

i've put out a call to the volunteers. someone should be in touch with you soon. you will need to confirm versions as above.

[unkempt cairn]

Its a Voron 2.4 r2 (from 2024)

[unkempt cairn]

Thank you! 🙂

[unkempt cairn]

I'd need to print this part : https://www.printables.com/model/315315-voron-clockwork-2-improved-latch

[shut mural]

check your DMs- you should have had a message from nico

[unkempt cairn]

I broke the HDMI port of my Pi... I am unable to launch my Voron 2.4, is it normal ?

[shut mural]

i can't think of a way those could be connected- what is your toolhead CAN connected to?

[shut mural]

are you using a usb can adapter like u2c?

[unkempt cairn]

I need to find a special plastic rail, the default ones for MG9H are too thick and makes it impossible to slide the MG9H into the tap rail... Do you know a special design to 3D print to make a mg9H slide perfectly into the tap rail ?

[shut mural]

not really a klipper issue any more.

but you don't need the plastic to get the carriage onto the rail- just slide the bare carriage down very carefully on its own

#voron_tap would be a more appropriate channel to continue

[unkempt cairn]

I've already killed 2 MH9H trying to do it without an adapted plastic rail

I'm still getting Error : ''extruder'' not hot enough. When launching a print, it warms up and suddently stops... I have no idea why, I will do firmware updates and report back later 😉 thx

[crisp pawn]

Do you have working qgl yet?

[unkempt cairn]

Yes I have QGL leveling working

[crisp pawn]

Then what does the console say before the extruder temperature error?

[unkempt cairn]

Nothing, it just warms up, the regular drill. Until is finish and is ready to start prin, then it crash aat this point.

I'll double check tonight

[latent sphinx]

Do you have a verify_heater section in your config ?

[crisp pawn]

Wrong error

Extruder not enough is related to the min_extrude_temp

Which generally comes up as a result of problems with start code

[unkempt cairn]

I'm discovering that my printer tends to slightly disconnects itself

Error during homing probe: Communication timeout during homing

[shut mural]

esoterical has a troubleshooting page on this error: https://canbus.esoterical.online/troubleshooting/timeout_during_homing_probing.html#timeout-during-homing-andor-probing

it would be useful to see a current klipper log too

the opening lines of that page are quite important- if this is happening all the time then something else is possibly at play

[unkempt cairn]

Is this klippy log enough to find out where the issue is coming from ?

[shut mural]

the log doesn't appear to contain the errors above (or anything much at all in terms of printer activity).

it does raise some questions though, like why you have microsteps set to 128 on X and Y, and why you have a 15x15 bed mesh- both things a CB1 will struggle with

[unkempt cairn]

15x15 bed mesh ? My bed size is 350x350, so I need to change it to 350x350 ? Yeah I remember struggling finding the correct microsteps and ended using 128 (which worked good). I think I have lots of issues, getting a bit confusing

[shut mural]

15 points by 15 points. not millimeters.

128 microsteps is a heck of a lot, dropping them to 32 and turning interpolate on will have the same result whilst reducing CPU workload

[unkempt cairn]

Can you briefly tell me what must I do ? To change the 15x15 mesh point and change 128microsteps to 32 ? I once tried to reduce the 128 to 32 microstep within my printer.cfg config but I had issues

[shut mural]

ignore the mesh for now.

what issues did you have- be specific

[unkempt cairn]

I only have this random issue is happends most of the time saying : error "extruder" not hot enough. It stops after doing QGL & Heating up, maybe just before or after the final mesh

[shut mural]

what is the error that appears just before "extrduer not hot enough

[unkempt cairn]

So the mesh might be causing the issue... I'm trying to figure out what is causing this error

[shut mural]

look in the console in mainsail- there will be some error preceding the not hot enough one

[unkempt cairn]

Usually none. I tripple check tomorrow when attempting a print again

[shut mural]

open a #request_help ticket when the error happens again

[unkempt cairn]

The last error i had : Error during homing probe : Communication timeout during homing

I need to try again few time cause its not consistant

[unkempt cairn]

I'm using TAP

[shut mural]

Stick to yesterdays ticket please
