Help with retraction. Retraction not working
-
Hello, I have a problem with the extruder. I have set the retraction speed 80mm / s z-hop 0.4mm retraction length 7mm.
I tried to change the speed in the slicer. The test tower printout is the same. I also tried setting the retraction in the config. And the same prints. It seemed to ignore the change.!

Which slicer are you using?
Also 7mm is a lot for direct drive 2mm max -

You have limited the extruder speed to 60mm/s....
Also the extruder acceleration is to low... -
This is an old setting, I forgot to upload the new one I have there.
I use Prusa slicer. I tried to give the acceleration like thisM203 X15000.00 Y15000.00 Z300.00 E5400.00
M566 X600 Y600 Z20 E3600
M201 X1000 Y1000 Z100 E5400M207 S7 F5400 Z0.4

So you are trying to set up firmware retraction?
Have you enabled the option in the slicer? -
Yes, retraction is disabled in the slicer. And is run set up firmware retraction.
-
@Paskal
You can trigger retraction by sending G10 in DWC and unretract by G11.
Is that working? -
Yes, retraction works in the printer web interface
-
@Paskal
Can you provide a current config?
I have found an issue with heater setting in the old one. -

Have you checked the slicer G-code?
Can you provide a sample? -

@Paskal
Where do you set the retraction settings?
I have base values in the config. And I overwrite them with the g-code of the filament settings.
Have you set them manually in DWC before starting a print? -
I have retraction settings in the config.g

Not in the old one.....
-
you still need to enable retraction in the slicer and then tick the box for firmware retraction.
The slicer then inserts G10 and G11 when retraction is required.
Otherwise, how will the firmware know?Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF

It's in the g-code

Part of the problem is the extremely long retraction, extremely low speed values for Z, and using Z hop. Z hop will always lead to a lot of stringing.
Try this for your settings
M566 X700 Y700 Z60 E3000 ; set maximum instantaneous speed changes (mm/min) M203 X6000 Y6000 Z600 E6000 ; set maximum speeds (mm/min) M201 X900 Y900 Z200 E3000 ; set accelerations (mm/s^2) M207 P0 S1.5 R0 F3600 T2600 Z0 ; retraction M572 S0 S0.05 ; pressure advance -

I changed the settings as recommended. I attach a photo, it seems better to me

Ok, now try calibrating the extruder: https://duet3d.dozuki.com/Guide/Ender+3+Pro+and+Duet+Maestro+Guide+Part+4:+Calibration/40#s165
-
Okay, I'll try. I calibrated it on PETG. But now I have PLA there, so I'll try again
-
@Phaedrux After calibration the result is the same. I tried to add length + speed and no change.
-
Photo of your extruder setup?
Is everything assembled correctly?
Do you have some fresh PLA to test with? -
@Phaedrux
As I mentioned yesterday, there is an issue in the provided config. Look at the configuration of H1.; Heaters M308 S0 P"bedtemp" Y"thermistor" T100000 B3950 ; configure sensor 0 as thermistor on pin bedtemp M950 H0 C"bedheat" T0 ; create bed heater output on bedheat and map it to sensor 0 M307 H0 A167.0 C982.2 D5.1 S1.00 V23.1 B0 ; enable bang-bang mode for the bed heater and set PWM limit M140 H0 ; map heated bed to heater 0 M143 H0 S120 ; set temperature limit for heater 0 to 120C M308 S1 P"spi.cs1" Y"rtd-max31865" ; define temperature sensor number 4 as a PT100 M950 H1 C"e0heat" T1 ; create nozzle heater output on e0heat and map it to sensor 1 M307 H0 B1 S1.00 M143 H1 S280 ; set temperature limit for heater 1 to 280CI'm not sure if it is already corrected or not. Nor what RRF is interprets in such a case.
But I know that higher temperatures lead to ozzing. -
Here is a photo of the hotend. Shouldn't the M143 have anything to do with it stringing or confusing?
