Ok ... thx

Hi please how to run PID tuning for BED ?
M303 T0 S205 runnig hotend, but not bed.

Here is a photo of the hotend. Shouldn't the M143 have anything to do with it stringing or confusing?

@Phaedrux After calibration the result is the same. I tried to add length + speed and no change.

Okay, I'll try. I calibrated it on PETG. But now I have PLA there, so I'll try again

@Phaedrux said in Help with retraction. Retraction not working:

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

I have retraction settings in the config.g

four_square_cons.gcode

Yes, retraction works in the printer web interface

Yes, retraction is disabled in the slicer. And is run set up firmware retraction.

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

M207 S7 F5400 Z0.4

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.!
Extruder BMG with E3D V6 directdrive.

It is Configconfig.g

P300 -> P1400 ( +100 )

P1500 -> P2400

Is it right for the test?

Thanks, I'm going to check out some script.

If I understand correctly M201 xy600 and M566 xy600

That's exactly what I was looking at, but I don't know what the appropriate settings are for my engines and printer.

Hi,
I have a problem tuning my printer. This is a Hypercube Evolution with 17 hs4401 engines. Settings here. Hotend is E3D V6 with BMG.
Thank you for the advice.
