#Error : "extruder" not hot enough

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]

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.

What does it say BEFORE the extruder not hot enough?

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

It works again ! 🙂

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

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

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

“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

#

The new one does!

#

(And yes, the new answer answers my question)

#

TAP system 🙂

crisp pawn
#

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

unkempt cairn

#

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

#

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 ,

?

#

it's needed to properly tension the extruder

#

you'll need to replace it

unkempt cairn
#

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! 🙁

#

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

#

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

Its a Voron 2.4 r2 (from 2024)
