Ejecting during filament loading
So, I've serviced my Core One this weekend, added the Core One Plus addons, removing the filtration unit due to heat creep problems. Firmware updated to latest 6.4.0. So far so good.
Now, when loading filament, the process works as expected, the sensor on the Nextruder side senses the filament. Changes the text, I press continue...
.. but when I continue, the printer wan'ts to eject. What's going on here?
If I bypass the wizard and simply move the E-dimension, everything works perfectly, I'ts just loading and unloading that seems off. As mentioned, the sensor seems to sense both when the filament is loaded and when it's unloaded.
The filament sensor passes calibration.
Tips would be greatly appreciated!

Right, or maybe the side sensor produces an intermittent signal? It seems likely that it is the root cause, since it is the only part in the filament path that got modified during the Core One + upgrade.

Wondering if the side filament sensor is getting stuck closed. Try disabling the sensor as a test.

RE:
Something about this new design is slightly off. On occasion I'm finding the tip of the filament is not lining up with the Bowden tube on the other side of the steel bearing and I have to twist slightly to insert it. I definitely don't see the point at all of this switch as well. The mod that moved the opposing magnet further away worked better.
The only reason I replaced it, is because I'm a completionist.
RE: Ejecting during filament loading
In the photographs provided the side filament sensor is showing "off" which means that the printer thinks the filament has run out and is prompting you to change the spool. You will need to troubleshoot why the side sensor is not detecting the presence of the filament.

RE: Ejecting during filament loading
Happened to me too two days ago. I found in internet that this happens if the side filament sensor is empty (no filament) and you try to load the filament, then it eject instead purge (don't ask me why...). In my case I didn't have a filament loaded but I wanted to do a cold pull.
RE: Ejecting during filament loading
I had the same thing happened to me! It was because I was doing a cold pull with no filament in the side sensor.
I was loading directly from the top of the head by removing the tubing.
I didnt know that side sensor was needed for cold pulls or loading in general.
