Help with retraction. Retraction not working

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?

It's in the g-code
I have checked that...

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

Paskal

@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?

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 280C

I'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?

@Paskal
Have a look on line 10, that should be H1. The line is overwriting the tunning of line 4.
So there is no M307 set for H1. Maybe RRF sets standard values, but I don't know.
You should also perform tunning for H1.
