Help with retraction. Retraction not working

Carlo

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

config.g

You have limited the extruder speed to 60mm/s....
Also the extruder acceleration is to low...

Paskal

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 this

M203 X15000.00 Y15000.00 Z300.00 E5400.00
M566 X600 Y600 Z20 E3600
M201 X1000 Y1000 Z100 E5400

M207 S7 F5400 Z0.4

So you are trying to set up firmware retraction?
Have you enabled the option in the slicer?

Paskal

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?

Paskal

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?

Paskal

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

Paskal

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.
