A10 part cooling fan

Hi,

I have a rev b A10. My part cooling fan stopped working.
If i measure the voltage when it is at 0% it reads 24.3 but when i put it to 100% it reads 19.3.

Any idea what has happened?

Thanks

Re: Titan extruder retraction noise

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 t...

Re: Titan extruder retraction noise

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.

Re: Auto fan

Well, i know it's importance, but when there is no printing happening, it is just making noise. While the ABL is running and waiting for the bed to heat up for e.g it is not neccessary to have it running. The Anycubic i3 mega works this way by default. It turns the hotend fan only when the hotend ha...

Re: Titan extruder retraction noise

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

Re: Titan extruder retraction noise

Hi,

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

Auto fan

Hi,,
Anybody has ever tried to use the auto fan feature of marlin?
For this i guess i need to configure the hotend cooler fan pin as auto fan pin

I would like to have my hotend cooler fan (not the part cooler) to run only when printing/reached a certain temperature only.

Thanks,
István
