Filament sensor wiring error

Jan 20, 2018 11:23 pm

Hello!
I just built my mk3 kit, when i go through the wizard i get a filament sensor wiring error. I've reseated all the connectors and checked continuity of the wires to ensure none of them were broken during assembly. anyone have any idea what could be going on here? Thanks!

Some sensors have been DOA, others have overheated massively and mine even went up in smoke after having been working. Contact support via the shop chat.

Wiring looks correct. Aside from bench testing the sensor, better to contact Support and have them send you a new one. Fingers crossed it isn't the Einsy board!

Just received my kit yesterday, built it today. Same error. What was the outcome for your printer?

I am about to reach out to support.

Thanks
Doug

Has anyone worked out how to disable the sensor temporarily? There's a menu function, but it seems to be unwilling to act if the sensor wiring error occurs. I'd be happy to bypass the sensor and get up and running while Tech Support works on this.

I'm in the same boat. Got my kit built today, "filament sensor wiring error". Triple checked the wiring, took the sensor out and gave it a good eyeballing, etc.

Can't get selftest to pass to get my printer up and running.

Just disconnect the sensor... Mine was malfunctioning... Prusa sent me a new one, but i`m using the printer without the sensor... the new one is on the bag ...
The self-test fails but you can print... :D

Replacement sensor fixed the issue for me.

Is the only answer to ask for a replacement? I have exactly the same problem . I also had to replace the PINDA probe cable because the connector was three pin not four pin.
