Replaced The Hot End, Now Having Loading Issues.
I replaced the hot end of my MK3+. Autoload wouldn't work, so I went to Settings > Move Axis > Extruder and manually inserted the filament. It was printing nicely but ran out of filament on the spool and just continued on. It didn't stop. Obviously, I've messed something up in my hot end replacement. Think both problems are related. Any ideas?
Best Answer by Robin_13:
Did you get the magnets wrong in the head assembly? There is a test location on the display for testing the sensor. I don't see the same display as you posted. If you have a volt meter, you can test the sensor and voltages on the three contacts. Red and black wires are power. If you measure between the black and white, when you install the filament you will see a change?

You probably wired the sensor up wrong check the wiring both ends also take a photo of the wiring both ends so we can check

It seems to be installed correctly. Maybe I bumped the wire on the motherboard when replacing the hot end wires. I'll check it after I'm done with my current print.
RE: Replaced The Hot End, Now Having Loading Issues.
Well, still having issues with this. It's continuing to print when it runs out of filament. I've replaced the IR sensor and cable.
Filament sensor is on.
In sensor state, I don't have IR, but I do have "Fil. Sensor" as a "1" and there's no filament in the printer.
Any ideas?

Thanks for the reply. I didn't touch the magnets so I didn't even think about it... however it's worth a check. I'll check it out and report back. Thanks.

No worries! Appreciate the input! Glad to get it sorted out and up and printing again.
RE: Replaced The Hot End, Now Having Loading Issues.
Glad you found the issue. At least the suggestion of the magnets helped to find the issue. I almost made that mistake when I rebuilt my head weeks ago. I also had an issue with the ball sticking. At the time, I replaced all my parts with ASA printed ones.
