Titan extruder retraction noise

[iherbak]

Hi,

Does anybody has titan extruder on the A10. It gives me hell of a noise on retraction. What could be the issue?

Thanks,

Hi, you can check if the motor can run normally.
If it is audible, you can replace the driver board to reduce it.

HI,

The motor is fine, with a standard extruder. I'm already replaced the steppers with TMC2208.
What else should i check?

Hi,

It is 5.4mm currently. The sound it gives me is like something is resonating.

when you replaced the drivers did you properly define the new drivers in marlin recompile and flash the correct settings to the printer?

Yes it is always making the noise. Yes the firmware has TMC2208_standalone for the drivers, and i also had to reverse the e0 direction as well.

With the stock extruder / and the geeetech metal extruder no such things happening. At very low retrraction 2mm it is better but that amount is just not enough to stop oozing.

As far as i can remember i set the vref to 0.8 on the extruder and a little bit below 0.8 for the XYZ.
It is kinda hot but can be touched with bare hands.

I already thought on putting back the old driver for the E0 to see if there is any difference.

i ran at 0.8v for a while and it was getting very hot like burn on touch hot i reduced them all to 0.7v to resolve that.
had filament melting inside the feeder causing issues as well.

OK I'll reduce the vrefs and see if it helps

I did the vref adjustment. Still the same issue see/hear the video i made https://youtu.be/PQlDJpYJjz4

looks like the spring tension is to low to keep a hold of the filament and its just spinning on the filament not even performing the retraction.

Will take a look. The tension is obviously good enough for printing as it does the job fine.
In the meanwhile i just disassembled the whole thing and only left the big wheel in.
Still the retraction is giving me the same noise. So it is not related to the tensino, nor the filament os the filament guide parts.

Still have no idea why it is giving me noise
