Advanced Filtration after printing / z-motors not being shut off
Hello,
I'm facing two issues with the Core One. Maybe someone has an idea:
1) After printing, the advanced filtration just stops, even though I set it to 10min filtration after printing. Does this depend on the filament type printed?
E.g. PLA: no filtration, ASA filtration
2) After printing, the z motors are not shut off. It's a whispering which is always present after printing until I disable all motors via the menu.
Many thanks in advance! 🙂

1. Correct, by default it only does this for certain materials (like PA/Nylon for example). If you go to the Chamber Filtration menu and scroll down, you can switch on "Filter All Materials"
2. I'm not sure what that is. If it is indeed coming from the motors then it is not normal.

RE:
Not sure the Z motors are turned off by default when a print ends…I would’ve thought that with a heavy print on the bed, if the z motors were disabled completely that would cause the bed to drop on its own.
Im not at my computer right now but if you check prusaslicer custom gcode -> end print it will tell you there what gets disabled when a print ends…I could well be completely wrong though 😂
what I know for sure though, if you disable all motors, it really doesn’t take much pressure near any one of the z screws to lower that part of the bed, and obviously when you do that the z alignment needs recalibrating…so Im guessing the z motors are left on so that re-alignment isn’t needed very often.

Yeah its as I suspected, in the end print gcode is this line :
M84 X Y E ; disable motors
So that's everything except Z disabled, I'm guessing for the reason I mentioned earlier regarding the Z-alignment.
If the noise is bugging you, you could add a 'Z' alongside X, Y & E, but you'll probably tilt the bed just removing the print from the plate, so unless you want to be recalibrating Z every print I'd leave it alone.

That's an interesting find. I don't recall any noise coming from the Z-axis motors (or maybe I'm getting old). As soon as my print finishes I have a listen. Makes sense what you are saying.

You won't hear anything until the heatbreak fan stops, which takes a fair while...mine makes a bit of noise, but nothing overly irritating.
There's a chance the noise that @dt_prusa is hearing is actually electronic noise coming from the driver chip on the main pcb.
